RadComboBox OnItemRequested

[George]

I am getting an error 'Cannot create an object of type 'Telerik.Web.UI.RadComboBoxItemsRequestedEventHandler' from its string representation 'rcbPersonGroupSelector_ItemsRequested' for the 'OnItemsRequested' property.' on the Rad combo box.

This is the code used :

<telerik:RadComboBox ID="rcbPersonGroupSelector" <br>    runat="server" Height="190px" Width="420px" MarkFirstMatch="true" EnableLoadOnDemand="true"<br>    HighlightTemplatedItems="true" OnItemDataBound="rcbPersonGroupSelector_ItemDataBound"<br>    OnItemsRequested="rcbPersonGroupSelector_ItemsRequested" IsCodeSet="false" Title="Select"><br>    <headertemplate><br>            <ul><br>            <li class="PersonSelector_col1">Name</li><br>            <li class="PersonSelector_col2">AAA</li>       <br>            </ul><br>            </headertemplate><br>    <ItemTemplate><br>        <ul><br>                <li class="PersonSelector_col1"><br>                <%#DataBinder.Eval(Container, "DataItem.Name") %>                    <br>                <li class="PersonSelector_col2"><br>                <%#DataBinder.Eval(Container, "DataItem.AAA") %>    <br>            </ul><br>    <br>    </ItemTemplate><br><span class="Apple-style-span" style="color: rgb(0, 17, 25); font-family: Consolas, 'Courier New', monospace; font-size: 13px; line-height: normal; "><span style="color: blue; "></</span><span style="color: maroon; ">telerik:RadComboBox</span><span style="color: blue; ">></span></span>

I have referenced telerik.web.ui and design dlls as suggested in one of the other threads, but still getting the same error.

Please help..

Thanks

Do you use RadComboBox for ASP.NET AJAX or RadComboBox for ASP.NET?
What is the version of Telerik.Web.UI that you use?
