OnClientContextMenuItemClicking

The OnClientContextMenuItemClicking client-side event occurs when the user clicks a menu item, but before the OnClientContextMenuItemClicked event fires. The event is called just prior to postback or url redirection and can be canceled.

The event handler receives parameters:

  1. The TreeView instance that fired the event.

  2. Event arguments with functions:

  • get_menuItem() retrieves a reference to the selected context menu item.

  • get_node() retrieves a reference to the clicked on node.

  • set_cancel() call this function to specify whether the event should be canceled (true) or not (false).

  • get_domEvent() retrieves the DOM event object of the item click.

The example below shows how to cancel the event if the text of the menu item is "Search"

ASPNET
<telerik:RadTreeView RenderMode="Lightweight" ID="RadTreeView1" runat="server" OnClientContextMenuItemClicking="ClientContextMenuItemClicking">
</telerik:RadTreeView>
