I want to exclude some columns from searching. I set the column AllowSearching = false. The column name is still showing in the 'Search in Columns' menu unchecked. Can I hide those columns? I tried :
DirectCast(DirectCast(e.ContextMenu, Telerik.WinControls.UI.RadDropDownButtonPopup).Items(0), Telerik.WinControls.UI.RadMenuItem).Items(i).Visibility = ElementVisibility.Hidden
It hides the menu item with the column name but showing a empty item in the position. Anyway I can make it disappear?
Thanks.
