Customize editors using params

The columns.editType is used to define the editor component for any particular column. You can set the columns.editType based on data type of the column.

Also, you can customize the behavior of the editor component through the columns.edit.params.

The following table describes editor component and their example edit params of the column.

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

If 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. We can restrict to type the decimal points in a NumericTextBox by using the validateDecimalOnType and decimals properties of NumericTextBox.

In the below demo, while editing the row we have restricted to type the decimal point value in the NumericTextBox of Freight column.

Provide custom data source and enabling filtering to DropDownList

You can provide data source to the DropDownList by using the columns.edit.params property.

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

Copied to clipboard
{
params: {
    query: new Query(),
    dataSource: country,
    fields: { value: 'ShipCountry', text: 'ShipCountry' },
    allowFiltering: true
    }
}

You can also enable filtering for the dropdownlist by passing the allowFiltering as true to the edit params.

In the below demo, DropDownList is rendered with custom Datasource for the ShipCountry column and enabled filtering to search dropdownlist items.

Open popup while focusing the edit dropdown list

You can open the DropDownList popup while focusing the cell by invoking the showPopup method inside the ‘focus’ event of DropDownList component.

In the below demo, we have bound the focus event for the edit DropDownList using the columns.edit.params property.

Custom editors using 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 TimePicker component while editing

Use the cell edit template feature of the Grid to render the TimePicker component in the Grid edit form. In the below sample, we have rendered TimePicker component in the OrderDate column.
