Using RadCombobox to trigger Servers side events

[FireHolster]

we are using the 2011.1.519.35 version of telerik.
We are trying to build a autocomplete functionality on a Radcombobox and to make it look like a text box.

I want to pupulate the autocomplete results by using a .ashx returning me a list of strings i need to display as autocomplete suggestions.

can someone help me to trigger this via a client side event like 'onItemsRequesting'. we want to trigger only if the text eneterd is greater than 2.????

My combobox looks like

 

<telerik:RadComboBox CssClass="radtextbox" AllowCustomText="true" ID="lastOrTrustNameTextBox"

 runat="server" ShowMoreResultsBox="True" EnableLoadOnDemand="True" ShowToggleImage="false"

 Style="margin: 20px auto; display: block !important;" OnClientDropDownOpening="HandleDropDownOpening">

 </telerik:RadComboBox>
function HandleDropDownOpening(sender, args) {

 args.set_cancel(true);

 }
