Syntax

Visual Basic
C#

'Declaration

'Usage
 
Dim instance As ColumnBase

Dim value As CellEditor

 

instance.CellEditor = value

 

value = instance.CellEditor

public CellEditor CellEditor {get; set;}

Property Value

The CellEditor that contains the information required to display the template that will be used to edit the content of the cells contained in the column as well as the activation gestures that activate the template. By default, a null reference (Nothing in Visual Basic).

Example

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.

The following examples demonstrates how to change the edit template of the cell editor for the ShipVia column to a Slider control.The following example demonstrates how to change the edit template of the cell editor for the Freight column to a custom calculator control. The C# code for the Calculate method called in the buttons' Click event simply calculates the new equation and is not provided. To shorten the code, some of the Button and KeyActivationGesture declarations have been removed.The following example demonstrates how to provide a default cell editor for columns that have an Int32 data type.
