Solution 2

I've solved this myself!

I replaced ScriptManager:

<asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown">
</asp:scriptmanager>

With ToolkitScriptManager:

<asp:toolkitscriptmanager runat="Server" xmlns:asp="#unknown">
</asp:toolkitscriptmanager>

Solution 1

Try This:-
add this in head tag

<meta http-equiv="X-UA-Compatible" content="IE=8" >

This will enable IE8 Standards mode
