RadComboBox OnClientItemsRequesting Context Problem

[Kayhan]

Hi All;

<script type="text/javascript">

 

        function ItemsRequesting(sender, args) {

            var context = args.get_context();

            context["FilterString"] = args.get_text();

            debugger;

        }

 

</script>



<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        <Scripts>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js">
            </asp:ScriptReference>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js">
            </asp:ScriptReference>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js">
            </asp:ScriptReference>
        </Scripts>
    </telerik:RadScriptManager>
    <telerik:RadComboBox runat="server" ID="RadComboBox1" Height="100px" EnableLoadOnDemand="true"
        ShowMoreResultsBox="true" EnableVirtualScrolling="true" EmptyMessage="Type here ..."
        OnClientItemsRequesting="ItemsRequesting">
        <WebServiceSettings Path="WcfDataService1.svc" Method="LoadData" />
</telerik:RadComboBox>

[ServiceContract(Namespace = "")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class WcfDataService1
    {
        [OperationContract]
        public RadComboBoxData LoadData(RadComboBoxContext context)
        {
           // Where is my context :-)
        }
    }

My problem isRadComboBoxContext context in the WebService is always null.
Does anyone know the reason?

Hi,

The issue that you describe is quite strange because your code looks alright. I tested it locally - it works as expected and the context object is not null.
Maybe this help article will give you a hint how to resolve the issue.
