  <p>Since yesterday, I've been trying to change values of various attribute of the Telerik tags in order to remove the Columns option.  I've modified/removed, and placed back various Telerik tag attributes like FilterCheckListEnableLoadOnDemand, FilterControlAltText, etc., but it still would not remove the Columns option.  Could someone please tell me what modifications in the code need to made in order to remove the Columns Option?</p>
