OnClientItemSelected

The OnClientItemSelected client-side event occurs immediately after certain item is selected.

The event handler receives two parameters:

1. The instance of the DropDownList firing the event.

2. An eventArgs parameter containing the following method:

   • get_item returns the item, that has just been selected.

Use this event to respond to the newly selected item:

ASPNET

	
<script type="text/javascript">
    function OnClientItemSelected(sender, eventArgs) {

        var item = eventArgs.get_item();
        alert("You selected " + item.get_text() + " with value " + item.get_value());

    }
</script>
