Cell edit type and its params

The columns.editType is used to customize the edit type of the particular column.
You can set the columns.editType based on data type of the column.

numericedit - NumericTextBox component for integers, double, and decimal data types.
defaultedit - TextBox component for string data type.
dropdownedit - DropDownList component for list data type.
booleanedit - CheckBox component for boolean data type.
datepickeredit - DatePicker component for date data type.
datetimepickeredit - DateTimePicker component for date time data type.

Also, you can customize model of the columns.editType component through the columns.edit.params.

The following table describes cell edit type component and their corresponding edit params of the column.

Component	Example
`NumericTextBox`	params: { decimals: 2, value: 5 }
`TextBox`	-
`DropDownList`	params: { value: ‘Germany’ }
`Checkbox`	params: { checked: true}
`DatePicker`	params: { format:’dd.MM.yyyy’ }
`DateTimePicker`	params: { value: new Date() }

If the edit type is not defined in the column, then it will be considered as the stringedit type (Textbox component).

Restrict to type decimal points in a NumericTextBox while editing the numeric column

By default, the number of decimal places will be restricted to two in the NumericTextBox while editing the numeric column. Restrict to type the decimal points in a NumericTextBox by using the validateDecimalOnType and decimals properties of NumericTextBox.

In the following demo, while editing the row, the decimal point values have been restricted to type in the NumericTextBox of the progress column.

Provide custom data source and enabling filtering to DropDownList

Provide the data source to the DropDownList by using the columns.edit.params property.

While setting a new data source using the edit params, you must specify a new query property too for the DropDownList as follows:

{
    this.priorityParams = {
            params: {
                allowFiltering: true,
                dataSource: new DataManager(this.prior),
                fields: { text: 'priorityType', value: 'priorityType' },
                query: new Query(),
                actionComplete: () => false
            }
        };
}

Enable filtering for the DropDownList by passing the allowFiltering as true to the edit params.

In the following demo, the DropDownList is rendered with the custom Datasource for the priority column and filtering is enabled to search the DropDownList items:

app.component.ts
app.module.ts

Cell edit template

The cell edit template is used to add a custom component for a particular column by invoking the following functions:

create - It is used to create the element at the time of initialization.
write - It is used to create the 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 RichTextEditor component while editing

Use the cell edit template feature of the tree grid to render the RichTextEditor component in the tree grid edit form. In the following sample, the RichTextEditor component is rendered in the taskName column, so the allowTextWrap property is used as true.
