Modalpopup called from contextmenu

[Yanling]

Hi all,

I use the ajaxcontroltoolkit modalpopupextender to make a ajax popup window without refreshing the page. But when the modalpopup window is called from the options in the contextmenu (no matter it is a contextmenu in treeveiw or radgrid), the page refreshes.

Any ideas?

Thanks.

Hi Yanling,

Have you handled the OnContextMenuItemClick event of the TreeView? If this is so, the Context Menu will postback the page whenever one of its Items is clicked.

You can prevent that by handling the client-side OnContextMenuItemClicking. If you cancel the event the event (if certain conditions are met), the server-side event will not fire.

        function clientContextMenuItemClicking(sender, eventArgs) {
            eventArgs.set_cancel(true);
        }

I hope this helps.

Hi Simon,

If I use eventArgs.set_cancel(true), the server code will not run. Then the modal popup will not show.

Hi Yanling,

In this case, use call the show() client side method of the ModalPopupExtender to show it manually after canceling the OnContextMenuItemClicking event.
