Commented Issue: AjaxToolkit not work in IE8 [27910]

Hi, AjaxToolkit not work on IE8.

I have a page that have registered dll:
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

This page inherit from master page that have an ScriptManager in it:
<asp:ScriptManager ID="asmGeneral" runat="server" AsyncPostBackTimeout="600" EnableScriptGlobalization="True"
EnableScriptLocalization="True"
OnAsyncPostBackError="asmGeneral_AsyncPostBackError" EnablePartialRendering="true">
<CompositeScript>
<Scripts>
<asp:ScriptReference Path="~/inc/js/jquery/jquery-1.11.1.min.js" />
<asp:ScriptReference Path="~/inc/js/general.js" />
</Scripts>
</CompositeScript>
</asp:ScriptManager>


I have in a page child of master the next code just to test the Toolkit and is painting the textBox as is it:
<asp:TextBox ID="Slider1" runat="server"></asp:TextBox>
<cc1:SliderExtender ID="SliderExtender1" runat="server"
TargetControlID="Slider1"
Minimum="-100"
Maximum="100"
Steps="5" />

This work fine in all browsers with version after IE8, but in IE8 not . If can help, i have in master the next meta-tag:
<meta http-equiv="X-UA-Compatible" content="IE=7, IE=9" />

i have updated to the last version of DevExpress but it remains without work...
Comments: Hi,   Would you describe in more detail what exactly doesn't work? Do you mean that SliderExtender is not shown? Or it just doesn't work and you get console error messages? We created a sample project based on your explanation, but all still works just fine. So, it would be extremely helpful if you attach a sample project for us to investigate it on our side. Best regards, Fadil
