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

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 time of initialization.
write - It is used to create custom component or assign default value at time of editing.
read - It is used to read the value from component at time of save.
destroy - It is used to destroy the component.
