Am trying to use the HeaderContextMenu for RadGrid to provide application-specific options. When I try to remove all the pre-defined options using this solution - http://www.telerik.com/community/forums/aspnet-ajax/grid/headercontextmenu-add-remove-items-vb-net.aspx#1284516 , the menu is not displayed at all. Specifically, when I remove the "Columns" option.
Is there any other way to do this? Or can I add in a HeaderContextMenu of my own to a specific column?
And I also tried to display the menu on left click using this snippet
function OnColumnClick(sender, args)
{
args.get_gridColumn().showHeaderMenu(args.domEvent);
}
But the menu doesn't stay expanded. It collapses immediately after it expands. Any ideas on how to make that work?
Thanks!

Any help regarding this issue would be appreciated.
Thank you.
Try downloading the next latest internal build and run the attached sample - the problem with the columns item should no longer be present.

I used the latest build with these release notes - http://www.telerik.com/versionnotes.aspx?nb=1&id=1254 and the problem still exists. So am guessing the build with the fix is yet to be available :)
Thanks!
The build that is currently in your account should have it.

The latest build I see in my account is named "Telerik.Web.UI_2011_1_503_Trial_hotfix" and the dll included in that build does not solve the problem.
Are the builds not available as am using the trial version?
And to give you more information I get a Javascript error near the line "var h=m.findItemByValue("ColumnsContainer").get_items();" within Telerik internal scripts.
Thank you.
Could you try the attached sample - I am sending it with the latest internal build dlls.
