Hello,
I have a page with the radgrid working.
What i wanted to do is after the render is complete, go to the header context menu object and remove some menu items that i don't want there.
When I add an OnPreRenderComplete to the code I get the 'Sys is not defined' error.
Any suggestions?
thanks.

I added a ContextMenu_PreRender(object sender, EventArgs e) and put the code in there and it worked.
Although i am still curious about the Sys error.
