Setting Event Handlers via JavaScript

You can use the client-side API of the RadPushButton control to modify the event handlers it calls.

To handle the desired event, the user should use the respective add_(handlerFunction) to attach the desired handler (i.e. add_clicked for the clicked event), where the parameter handlerFunction should be of type function. To remove a handler that has been added previously, the respective remove_(handlerFunction) should be used.

Here follows examples showing how to add and remove handlers on the client:

Example 1: Adding named (non-anonymous) JavaScript click handler to RadPushButton.

ASP.NET

<script type="text/javascript">
	function Click(button, args)
	{
		alert("Button was clicked");
	}
	function addHandler()
	{
		var button = $find("<%=RadPushButton1.ClientID %>");
		button.add_clicked(Click);
	}
</script>

Example 2: Adding anonymous JavaScript click handler to RadPushButton.

ASP.NET

<script type="text/javascript">
	function Click(button, args, arg1)
	{
		alert("Button was clicked. arg1: " + arg1);
	}
	function addHandler()
	{
		var button = $find("<%=RadPushButton1.ClientID %>");
		button.add_clicked(function (button, args) { Click(button, args, "Value1") });
	}
</script>

Example 3: Removing JavaScript click handler of RadPushButton.

JavaScript

function removeEvents()
{
    var button = $find("<%= RadPushButton1.ClientID %>");
    button.remove_show(Click);
}
