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
