Attaching the event

In the Markup

<telerik:RadGrid ID="RadGrid1" runat="server" OnCreateColumnEditor="RadGrid1_CreateColumnEditor">
</telerik:RadGrid>

In the Code behind

protected void Page_Init(object sender, EventArgs e)
{
    RadGrid1.CreateColumnEditor += RadGrid1_CreateColumnEditor;
}
Protected Sub Page_Init(sender As Object, e As EventArgs) Handles Me.Init
    AddHandler RadGrid1.CreateColumnEditor, AddressOf RadGrid1_CreateColumnEditor
End Sub

The event handler

protected void RadGrid1_CreateColumnEditor(object sender, GridCreateColumnEditorEventArgs e)
{
    GridColumn column = e.Column;
    IGridColumnEditor columnEditor = e.ColumnEditor;
}
Protected Sub RadGrid1_CreateColumnEditor(ByVal sender As Object, ByVal e As GridCreateColumnEditorEventArgs)
    Dim column As GridColumn = e.Column
    Dim columnEditor As IGridColumnEditor = e.ColumnEditor
End Sub

Examples

Attaching a custom column editor programmatically

In a CreateColumnEditor event handler, you can attach an instance of your custom editor to a column by assigning the e.ColumnEditor parameter of the handler:

protected void RadGrid1_CreateColumnEditor(object sender, Telerik.Web.UI.GridCreateColumnEditorEventArgs e)
{
    GridBoundColumn column = e.Column as GridBoundColumn;
    if (column != null && column.DataField == "ShipAddress")
    {
        e.ColumnEditor = new MyMultiLineTextBoxColumnEditor(column);
    }
    if (column != null && column.DataField == "OrderDate")
    {
        e.ColumnEditor = new MyDateColumnEditor(column);
    }
}
Private Sub RadGrid1_CreateColumnEditor(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCreateColumnEditorEventArgs) Handles RadGrid1.CreateColumnEditor
    Dim column As GridBoundColumn = TryCast(e.Column, GridBoundColumn)
    If column IsNot Nothing AndAlso column.DataField = "ShipAddress" Then
        e.ColumnEditor = New MultiLineTextBoxColumnEditor(column)
    End If
    If column IsNot Nothing AndAlso column.DataField = "OrderDate" Then
        e.ColumnEditor = New DateColumnEditor(column)
    End If
End Sub
