  I am trying to implement a rating system. I am using visual studio 2013 c# website. I keep receiving this same error and don't know what is causing it.

  System.InvalidCastException: Specified cast is not valid.
  Line 45:                     <cc1:Rating ID="Rating"

  This is the front end of my code I have used a gridview tool with ajax rating inside it as I am bringing in a lot of data from my access 2007 database which is connected.

  I have one table called machine in my database which has the fields; id ,make ,type ,manufacturer ,customer rating ,image and rating.

  this is the front end of my code for the gridview.

  <cc1:ToolkitScriptManagerID="ToolkitScriptManager1"runat="server">
