Setting Event Handlers via JavaScript

You can use the client-side API of the RadLinkButton 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 is an example showing how to add handler on the client:

• Adding named (non-anonymous) JavaScript function

  ASP.NET

    <script type="text/javascript">
    	function Click(button, args)
    	{
    		alert("Button was clicked");
    	}
    	function addHandler()
    	{
    		var button = $find("<%=RadLinkButton1.ClientID %>");
    		button.add_clicked(Click);
    	}
    </script>

• Adding anonymous JavaScript function

  ASP.NET

    <script type="text/javascript">
    	function Click(button, args, arg1)
    	{
    		alert("Button was clicked. arg1: " + arg1);
    	}
    	function addHandler()
    	{
    		var button = $find("<%=RadLinkButton1.ClientID %>");
    		button.add_clicked(function (button, args) { Click(button, args, "Value1") });
    	}
    </script>
