Property Value

If specified, the OnClientNodePopulationFailed client-side event handler is called when the operation to populate the children of a tree node has failed. Two parameters are passed to the handler:

• sender, the menu client object;
• eventArgs with three properties:
  • get_node(), the instance of the tree node.
  • set_cancel(), set to true to suppress the default action (alert message).

This event cannot be cancelled.

<script type="text/javascript">
function onClientNodePopulationFailedHandler(sender, eventArgs)
{
var node = eventArgs.get_node();
var errorMessage = eventArgs.get_errorMessage();

alert("Error: " + errorMessage);
eventArgs.set_cancel(true);
}
</script>
