I am using a drop down list which has auto-postback enabled as the option selected will enable a particular view in a multiview control. I am using the ajax update panel in order to prevent the post backs appearing to the user and showing the page being reloaded. However, the control seems to be throwing an error. The error occurs in the function "igtbl_submit()" in the file "Resource.axd" which appears to be automatically generated by .net. The exact error message that I am getting is: "Microsoft JScript runtime error: 'window.__thisForm.igtblGrid' is null or not an object"

Any suggestions
