    We are using version 2010.3.1317.35.

    I'm currently having an issue with the Filter feature of the control on IE9. 
    It works as expected on Chrome 15 and FF7.

    Here's the exact code I am using:
    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
        <head runat="server">
            <form id="form1" runat="server">
                    <asp:ScriptManager ID="ScriptManager1" runat="server">
                    <telerik:RadComboBox ID="testRadCombo1" runat="server" Filter="Contains"
                            <telerik:RadComboBoxItem Text="AAA" Value="1" />
                            <telerik:RadComboBoxItem Text="AAB" Value="2" />
                            <telerik:RadComboBoxItem Text="AAC" Value="3" />
                            <telerik:RadComboBoxItem Text="BBB" Value="4" />
                            <telerik:RadComboBoxItem Text="BBA" Value="5" />
                            <telerik:RadComboBoxItem Text="BBC" Value="6" />
                            <telerik:RadComboBoxItem Text="CCC" Value="7" />
                            <telerik:RadComboBoxItem Text="CCA" Value="8" />
                            <telerik:RadComboBoxItem Text="CCB" Value="9" />

    On IE, the Filter feature just doesn't work and we are very frustrated with it. I spent more than an hour reading documentation and other sites and forums to find a solution and/or what I'm doing wrong before I decided to write here.

    Is there anything I'm missing here? Is there any extra configuration for IE? Is IE no longer supported? What should we do?

    Repeating: It works as expected on Chrome 15 and FF7


    Update: I've modified the aspx page by adding a meta tag as follows:

    <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

    This seems to keep the behavior compatible with other browsers, and of course, IE9.

    Wish I didn't have to do this and that it would work the same on all browsers.

    Hello Thiago,

    IE 9, FireFox 4 and Google Chrome10 are supported by controls starting Q1 2011. If you would like to ensure that our AJAX controls are compatible with the new major versions of these three browsers, you will need to migrate at least to version 2011.1.315. With older versions these browsers are only partially supported.
    Updating RadControls for ASP.NET AJAX to another version or license.
