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
Hello Sushma,
Probably your code is executing too early. Try to put it after Script Manager control on the page. http://news.infragistics.com/forums/p/41012/232750.aspx#232750
