Edit types in Angular TreeGrid component
5 Apr 202524 minutes to read
The Angular TreeGrid component in Syncfusion® provides various edit types that allow you to customize the editing behavior for different types of columns. These edit types enhance the editing experience and provide flexibility in handling different data types.
Default cell edit type editor
The Tree Grid provides pre-built default editors that enhance data editing and input handling within the tree grid. These default editors are designed to simplify the process of defining the editor component for specific columns based on the data type of the column within the tree grid. To configure default editors for tree grid columns, leverage the editType property of column.
The available default edit types are as follows:
| Component | Edit Type value | Description |
|---|---|---|
| TextBox | stringedit | The stringedit type renders a TextBox component for string data type columns. |
| NumericTextBox | numericedit | The numericedit type renders a NumericTextBox component for integers, double, float, short, byte, long, long double and decimal data types columns. |
| DropDownList | dropdownedit | The dropdownedit type renders a DropdownList component for string data type columns. |
| Checkbox | booleanedit | The booleanedit type renders a CheckBox component for boolean data type columns. |
| DatePicker | datepickeredit | The datepickeredit type renders a DatePicker component for date data type columns. |
| DateTimePicker | datetimepickeredit | The datetimepickeredit type renders a DateTimePicker component for date time data type columns. |
The following example demonstrates how to define the editType for tree grid columns:
<e-column field="taskName" headerText="Task Name" editType="stringedit"></e-column>
<e-column field="duration" headerText="Duration" editType="numericedit'"></e-column>
<e-column field="priority" headerText="Priority" editType="dropdownedit"></e-column>
<e-column field="startDate" headerText="Start Date" editType="datepickeredit"></e-column>
<e-column field="endTime" headerText="End Time" editType="datetimepickeredit"></e-column>
<e-column field="approved" headerText="Approved" editType="booleanedit"></e-column>If
editTypeproperty is not defined in the column, then it will be considered as the stringedit type (TextBox component) .
Customize TextBox component of stringedit type
You can customize the default TextBox component in Tree Grid edit form using its property. This customization allows you to configure various properties of the TexBox, tailoring its behavior and appearance to match your specific requirements within the tree grid. The behavior of the editor component can be fine-tuned through the columns->edit->params property.
| Component | Edit Type | Description | Example Customized edit params |
|---|---|---|---|
| TextBox | stringedit | The stringedit type renders a TextBox component for string data type columns. To customize the TextBox component, refer to the TextBox API documentation for detailed information on available properties |
params: { showClearButton : true} |
The following sample code demonstrates the customization applied to TextBox component of taskName column in tree grid:

By default, the NumericTextBox component allows entering decimal values with up to two decimal places when editing a numeric column. However, there might be cases where you want to restrict input to whole numbers only, without any decimal points. In such scenarios, you can make use of the validateDecimalOnType and decimals properties provided by Syncfusion’s NumericTextBox component.
The validateDecimalOnType property is used to control whether decimal points are allowed during input in the NumericTextBox. By default, it is set to false, allowing decimal points to be entered. However, when set to true, decimal points will be restricted, and only whole numbers can be entered.
The decimals property specifies the number of decimal places to be displayed in the NumericTextBox. By default, it is set to 2, meaning that two decimal places will be displayed. However, you can modify this value to customize the decimal places according to your requirements.
In the below demo, while editing the row the decimal point value is restricted to type in the NumericTextBox of Duration column.

You can customize the DropDownList component in Tree Grid edit form using its property. This customization allows you to configure various properties of the DropDownList, tailoring its behavior and appearance to match your specific requirements within the tree grid. The behavior of the editor component can be fine-tuned through the columns->edit->params property.
| Component | Edit Type | Description | Example Customized edit params |
|---|---|---|---|
| DropDownList- | DropDownEdit | The dropdownedit type renders a DropDownList component for string data type columns. To customize the DropDownList component, refer to the DropDownList API documentation for detailed information on available properties. |
params: { value: ‘High’ } |
The following sample code demonstrates the customization applied to DropDownList component of priority column in the tree grid:

In TreeGrid component, you have an option to provide a custom data source for the DropDownList component in the edit form. This feature allows you to define a specific set of values for the DropDownList.
To achieve this, you can utilize the columns->edit->params property. This property allows you to define the edit params for the column within the tree grid.
When setting a new data source using the edit params, you need to specify a new query property for the DropDownList. The query property allows you to define custom queries for data retrieval and filtering.
In the below demo, DropDownList is rendered with custom data source for the Priority column :

The TreeGrid component provides filtering for the DropDownList within the edit form. This feature allows to select options from a predefined list and easily search for specific items using the built-in filtering feature.
To enable filtering, set the allowFiltering property to true within the edit params. This will enable the filtering feature in the DropDownList.
In the following demo, filtering is enabled for the Priority column:

bootstrapApplication(AppComponent).catch((err) => console.error(err));Open popup while focusing in the edit cell
You can open the dropdown edit popup with a single click by focusing the dropdown element. This feature allows you to quickly access and interact with the dropdown options without the need for an additional click.
To achieve this, you can utilize the showPopup method provided by the EJ2 DropDownList component. This method can be invoked within the actionComplete event of the tree grid, which triggers when an action, such as editing, is completed. By calling the showPopup method in this event, you can open the popup for the dropdown edit.
To ensure that the dropdown column is the clicked edit target, you need to set a global flag variable in the mouseup event along with load event. This flag variable will be used to determine if the clicked element corresponds to the dropdown column.
The following sample demonstrates how to open the popup when focusing on the edit cell using the actionComplete and load events:

You can customize the DateTimePicker component in Tree Grid edit form using its property. This customization allows you to configure various properties of the DateTimePicker, tailoring its behavior and appearance to match your specific requirements within the tree grid. The behavior of the editor component can be fine-tuned through the columns->edit->params property.
| Component | Edit Type | Description | Example Customized edit params |
|---|---|---|---|
| DateTimePicker | datetimepickeredit | The datetimepickeredit type renders a DateTimePicker component for date time data type columns. You can customize the DateTimePicker component, refer to the DateTimePicker API documentation for detailed information on available properties. |
params: { value: new Date() } |
The following sample code demonstrates the customization applied to DateTimePicker component of startDate column in the tree grid:

Accessing editor components in the Tree Grid allows you to interact with the editor instances associated with cells during editing or adding actions. This feature is especially useful when you need to perform custom actions, retrieve data from the Editor, or manipulate its properties during editing or adding operations in the tree grid.
To access the component instance from the component element, you can use the ej2_instances property. This property provides access to the instance of the editor component associated with a cell.
In the below demo, you can access the editor component instance while adding or editing actions in the actionComplete event.

bootstrapApplication(AppComponent).catch((err) => console.error(err));Render custom cell editors
The Tree Grid allows you to render custom cell editors for particular columns. This feature is particularly useful when you need to use custom components to edit the data within a tree grid column. To achieve this, you can make use of the editTemplate of the column in TreeGrid component.
Custom components inside the
editTemplatemust be specified with two-way (@bind-Value) binding to reflect the changes in tree grid.
Render textArea in edit form
The Tree Grid allows you to render a textArea within the tree grid’s edit form for a specific column. This feature is especially valuable when you need to edit and display multi-line text content, providing an efficient way to manage extensive text data within the tree grid’s columns.
To render a textArea in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
When using a text area, press Shift+Enter to move to the next line. By default, pressing Enter will trigger a record update while you are in edit mode.
The following example demonstrates how to render a textArea component in the Task Name column of the tree grid. The valueAccessor property is utilized to split the text into multiple lines within the treegrid column:

bootstrapApplication(AppComponent).catch((err) => console.error(err));Prevent the enter key functionality in multiline textbox while editing
While editing a particular row in dialog or row edit mode, pressing the ENTER key will save the changes made in the specific cell or edit form. Similarly, pressing the ENTER key while performing editing with the multiline textbox will save the changes. However, in a multiline textbox, it is often desired that pressing the ENTER key adds a new line break in the text content, rather than triggering the save action.
To achieve this behavior, you can utilize the stopPropagation method along with the focus event of the textBox component. This prevents the default behavior of the ENTER key, allowing you to manually handle the newline behavior.
The following example demonstrates how to prevent the enter key functionality in multiline textbox during editing by utilizing the focus event:

bootstrapApplication(AppComponent).catch((err) => console.error(err));Render AutoComplete component in edit form
The Tree Grid allows you to render a AutoComplete component within the tree grid’s edit form for a specific column. This feature is especially valuable when you need to provide a dropdown-like auto-suggestion and input assistance for data entry in the tree grid’s columns.
To render a AutoComplete component in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
The following example demonstrates how to render an AutoComplete component in the taskName column of the tree grid. The actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:
import { NgModule, } from '@angular/core';

];Render MaskedTextBox component in edit form
The Tree Grid allows you to render a MaskedTextBox component within the tree grid’s edit form for a specific column. This feature is especially useful when you need to provide masked input fields that require a specific format, such as phone numbers or postal codes.
To render a MaskedTextBox component in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
Here’s an example of how to render a MaskedTextBox component in the Contact column of the tree grid. The actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:
import { NgModule, } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser'

The Tree Grid allows you to render a DropDownList component within the tree grid’s edit form for a specific column. This feature is valuable when you need to provide a convenient way to select options from a predefined list while editing data in the tree grid’s edit form.
To render a DropDownList component in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
The following example demonstrates how to render a DropDownList component in the taskName column of the Tree Grid .The actionBegin event is handled to update the edited value in the grid when the save button is clicked:
import { NgModule, } from '@angular/core';

The Tree Grid allows you to render images in the DropDownList editor component. This feature is valuable when you want to display images for each item in the dropdown list of a particular column, enhancing the visual representation of your data.
To render a DropDownList in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
To display an image in the DropDownList editor component, you can utilize the itemTemplate property. This property allows you to customize the content of each item in the dropdown list.
The following example demonstrates how to render images in the DropDownList editor component using the itemTemplate within the EmployeeID column of the Syncfusion® Grid. Additionally, the actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:

bootstrapApplication(AppComponent).catch((err) => console.error(err));Render Multiple columns in DropDownList component
The Tree Grid allows you to render a DropDownList component within the tree grid’s edit form for a specific column. This feature is particularly useful when you want to display more detailed information for each item in the dropdown list during editing a specific column.
To render a DropDownList in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
The DropDownList has been provided with several options to customize each list item, group title, selected value, header, and footer element. By default, list items can be rendered as a single column in the DropDownList component. Instead of this, multiple columns can be rendered. This can be achieved by using the headerTemplate and itemTemplate properties of the DropDownList component.
The following example demonstrates how to render a DropDownList component with multiple columns within in the Task Name column. The actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:
import { NgModule, } from '@angular/core';
import { DropDownListModule } from '@syncfusion/ej2-angular-dropdowns'
import { BrowserModule } from '@angular/platform-browser'

bootstrapApplication(AppComponent).catch((err) => console.error(err));Render ComboBox component in edit form
The Tree Grid allows you to render a ComboBox component within the tree grid’s edit form for a specific column. This feature is especially valuable when you need to provide a drop-down selection with auto-suggestions for data entry.
To render a comboBox component in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
The following example demonstrates how to render a ComboBox component in the Task Name column of the tree grid. The actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:
import { FormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser'

bootstrapApplication(AppComponent).catch((err) => console.error(err));Render MultiSelect component in edit form
The Tree Grid allows you to render a MultiSelect component within the tree grid’s edit form, enabling you to select multiple values from a dropdown list when editing a specific column. This feature is particularly useful when you need to handle situations where multiple selections are required for a column.
To render a MultiSelect component in the edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
The following example demonstrates how to render a MultiSelect component in the Task Name column of the tree grid. The actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:
import { NgModule, } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser'

The Tree Grid allows you to render the RichTextEditor component within the edit form. This feature is valuable when you need to format and style text content using various formatting options such as bold, italic, underline, bullet lists, numbered lists, and more during editing a specific column.
To render RichTextEditor component in edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
Additionally, you need set the allowTextWrap property of the corresponding tree grid column to true. By enabling this property, the rich text editor component will automatically adjust its width and wrap the text content to fit within the boundaries of the column.
The following example demonstrates how to render a RichTextEditor component in the taskName column of the tree grid. The actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:

The Tree Grid allows you to render an Upload component within the tree grid’s edit form. This feature is especially valuable when you need to upload and manage files or images in a specific column during data editing.
To render Upload component in edit form, you need to define an editTemplate for the column using ng-template. The editTemplate property specifies the cell edit template that used as an editor for a particular column. It can accept either a template string or an HTML element ID.
The following example demonstrates how to render a Upload component in the Image column of the tree grid. The actionBegin event is handled to update the edited value in the tree grid when the save button is clicked:

bootstrapApplication(AppComponent).catch((err) => console.error(err));Render custom cell editors using external function
The Tree Grid provides the ability to render custom cell editors, allowing you to add custom components to specific columns in your tree grid using the cell edit template feature. This feature is useful when you need to edit cell values using custom input elements or controls.
To utilize the custom cell editor template feature, you need to implement the following functions:
-
create - It is used to create the element at the time of initialization.
-
write - It is used to create custom component or assign default value at the time of editing.
-
read - It is used to read the value from the component at the time of save.
-
destroy - It is used to destroy the component.
Render AutoComplete component in edit form
The Tree Grid allows you to render the AutoComplete component within the edit form by using the cell edit template feature.This feature enables you to select values from a predefined list during the editing of a specific column. It is especially valuable when you need to provide a dropdown-like auto-suggestion and input assistance for data entry in the tree grid’s columns.
To achieve this, you need to utilize the columns->edit property along with a defined object that specifies the necessary functions for creating, reading, and writing the auto complete component.
The following example demonstrates how to render a Autocomplete component in the Task Name column:
import { NgModule, } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser'
import { TreeGridAllModule } from '@syncfusion/ej2-angular-treegrid';

bootstrapApplication(AppComponent).catch((err) => console.error(err));Render cascading DropDownList component in edit form
The Tree Grid allows you to render the cascading DropDownList within the edit form by using the cell edit template feature.This feature is especially useful when you need to establish a hierarchy of options, such as choosing a country and then selecting a state based on the chosen country.
To achieve this, you need to utilize the columns->edit property along with a defined object that specifies the necessary functions for creating, reading, and writing the auto complete component.
In the below demo, cascading DropDownList rendered for Priority and Duration column.
