Filter not working for RadCombobox

[Rajesh]

Hi,

I have created a RadCombo control and binded some values to it. I want to add filter to that combobox and applied the filter value using Filter="Contains" property as seen in the code below. When I expect the values to be filtered, it does not. Please find the screenshot attached. 

btw, I have referenced the script resource assembly i.e. axd file in the web.config (included) and is there anything wrong in that file. 
Am I missing anything ? 

  

<form id="form1" runat="server">
   <div>

    <telerik:RadScriptManager runat="server" ID="RadScriptManager1">

    </telerik:RadScriptManager>
    <table>
       <tr>
           <td><telerik:RadComboBox ID="RadComboBox1" runat="server" Width="186px"  AutoPostBack="true"  EnableLoadOnDemand = "true" Filter="Contains" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged" Label="Country:" /></td>
           <td><telerik:RadComboBox ID="RadComboBox2" runat="server" Width="186px" AllowCustomText="true" Filter="Contains" Label="Province:" OnSelectedIndexChanged="RadComboBox2_SelectedIndexChanged" /></td>
       </tr>
        <tr>
           <td>Country : <asp:Label ID="lblCountry" runat="server" Text=""></asp:Label> </td>
           <td>Province :<asp:Label ID="lblProvince" runat="server" Text=""></asp:Label></td>
       </tr>
    </table>
     <asp:XmlDataSource runat="server" id="XmlDataSource1" XPath="Countries"
           DataFile="~/App_Data/CountryRegionMapping.xml"/>

Hi Rajesh,

 
Thank you for contacting Telerik support.

I have inspected and tested the code that you shared but could not reproduce the described unusual behavior. Would you please share the code behind so we could take a look at it as well and be more helpful?

Greetings,
