    In my application, when a user clicks on an item in the RadListview, I want a clientside JavaScript function to be called (similar to onclientclick in an asp.net control).
    How would I call a client side JavaScript function when "RadListView1_SelectedIndexChanged" event is triggered ?

    Hi,

    We have exposed a client-side event that you can intercept but I am not sure that it will meet your requirements. I suppose that you use a SelectedItemTemplate in your implementation and this presents a problem. Now in order to initiate this template a trip to the server has to be performed. This means that you can not avoid a postback. The client-side OnItemSelected event will be fired when an item is selected using the selectItem method like demonstrated below:
    function pageLoad(sender,args)
           {
                   var listView = $find("<%= RadListView1.ClientID %>");
                   listView.selectItem(0, true);
           }

    Following this approach you will avoid a postback thus the SelectedItemTemplate will not be initialized. If you want to fire some JavaScript event when selecting the item you can attach a OnClientClick event handler to the button which you use for selecting.

    Please clarify the requirements and explain why you need to call a method in the client-side so we could give you a more precise advise.
