Namespace: Kettic.AspNet.Controls
Assembly: Kettic.AspNet.Controls (in Kettic.AspNet.Controls.dll) Version: 2014.4.1129.0 (2014.04.1129.0)
SyntaxProperty Value
Type: StringA string specifying the name of the JavaScript function that will handle the event. The default value is empty string.
RemarksIf specified, the OnClientShowing client-side event handler is called before the context menu is shown on the client. Two parameters are passed to the handler:
- sender, the menu client object;
- eventArgs with two properties, get_cancel()/set_cancel(cancel) and get_domEvent (a reference to the browser event).
The OnClientShowing event can be cancelled. To do so, set the cancel property to false from the event handler (e.g. eventArgs.set_cancel(true);).
Examples
The following example demonstrates how to use the
OnClientShowing property.

var shouldDisplayContextMenu = confirm("Do you want to enable context menus on this page?"); function onClientShowingHandler(sender, eventArgs)
{
eventArgs.set_cancel(!shouldDisplayContextMenu);
}
</script>
var shouldDisplayContextMenu = confirm("Do you want to enable context menus on this page?"); function onClientShowingHandler(sender, eventArgs)
{
eventArgs.set_cancel(!shouldDisplayContextMenu);
}
