Sys.ArgumentTypeException Error

0 (0votes)

In this blog I will explain how to overcome the error: Sys.ArgumentTypeException: Object of type 'Sys._Application' cannot be converted to type 'Sys._Application'. Parameter name: instance. This error Generally comes when we are dealing with ajax and using script manager. So to remove that error add ScriptMode ="Release" attribute to your script manager.

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="True" ScriptMode ="Release" ></asp:ScriptManager>

Happy Reading .!
