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>
