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>

JavaScript

function ClientContextMenuItemClicking(sender, eventArgs) {
	var node = eventArgs.get_node();
	var item = eventArgs.get_menuItem();

	if ((item.get_text() == "Network Search") && (node.get_text() == "Printers")) {
		eventArgs.set_cancel(true);
	}
}
