Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object
posted

Hello:

I am using Infragistics NetAdvantage ASP.NET 2010.3. I am using the Ultra Web Grid here.

It was all working fine when I had IE7 on my system. Now since our systems were updated with the  IE8 browser., I keep getting JScript runtime error when I try to access this page.

Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object

Please could you tell me what the problem. If I run the same page on FireFox, Chrome or Safari, I do not get this JavaScript

Please could you get back with me ASAP,

Regards,

Sushma
