Prevent Columns from being shown / hidden

[Lee]

I have to enable the header context menu on my grid as I want use it for filtering. Is there a way I can enable it but prevent the additional options in the context menu. The main one I want to remove is the hiding / showing of columns

Hello,

For more information how to customize the header context menu items refer to the below article:
http://www.telerik.com/help/aspnet-ajax/grid-header-context-menu.html
See how the menu items are accessed in the last section and after accessing them you can simply hide them by setting display false.
