Hello,

I would like to have a Context Menu for a Header of a RadGrid that consists of the "Columns" part of the normal Context Menu and some other options I'd like to add myself (the Menu should not have the other normal Options like "Sort Ascending" visible).
Is there an easy way to achieve that functionality for the Context Menu of the Header, or is there an easy way to implement Check Boxes for the Menu Items of the Context Menu control to look familiar to the "Columns" part of the Header Context Menu of the Rad Grid control?

Thank you very much in advance,
Robin

Hello Robin,

I believe it will be very helpful if you check out the following thread where the requested functionality is discussed:
 Customize Header Context Menu

An alternative approach would be to use the HeaderMenuShowing client side event and configure the menu per your requirements as demonstrated in the demo below:
 
<ClientEvents ... OnHeaderMenuShowing="headerMenuShowing">
 JavaScript:
function headerMenuShowing(sender, args) {
    var menu = args.get_menu();
    menu.get_items().clear();
    var newItem = new Telerik.Web.UI.RadMenuItem();
    newItem.set_text("Clicked: " + args.get_gridColumn().get_uniqueName());
    menu.get_items().add(newItem);
}

Menu / Add/Remove/Disable Items

I hope this will prove helpful.
