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:
listView = $find(
"<%= RadListView1.ClientID %>"
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.
