OnClientItemsRequested

The OnClientItemsRequested client-side event occurs after the load-on-demand mechanism has added new items to the combobox.

The event handler receives two parameters:

  1. The instance of the combobox firing the event.

  2. An eventArgs parameter containing the following method:

  • get_text returns the text that has been typed in the input field to fire the ItemsRequested event. This text is the same text that is passed to the ItemsRequested server event.

  • get_domEvent() returns the DOM event object.

Use this event to perform client-side actions once the new items are bound to the combobox:

<script language="javascript" type="text/javascript">
    function OnClientItemsRequested(sender, eventArgs) {
        alert("There are now " + sender.get_items().get_count() + " items.");
    }
 </script>

<telerik:radcombobox
    id="RadComboBox1" 
    runat="server" 
    onclientitemsrequested="OnClientItemsRequested"
    enableloadondemand="true" 
    onitemsrequested="RadComboBox1_ItemsRequested">
</telerik:radcombobox>
