I have a WebApplication running in customers enviroment. The customers are getting sporadicly exceptions of Type System.Xml.XmlException.
Here is the stack trace:

Any ideas how to solve this problem?
Hallo David Young,
thank you for fast reply. You are right. My grid is inside a updatepanel, which is inside a UltraWebTab, which is inside a page which is inside a master page.
My Infragistics Version is 10.2.20102.2173
Is there a known issue, which is fixed in later version? If so I try an update.OK I will check the effort replacing all UltraWebTabs with new WebTab.
My problem is, that I can not reproduce it. It only happens on the customers enviroment. So I have no test project.
Hi ThomasHepp,
It looks as if your grid is inside of an update panel in an UltraWebTab in a MasterPage? What version of Infragistics controls do you have and do you have the latest Service Release. I'd suggest upgrading to the new WebTab as the UltraWebTab will be getting retired. If you could attach a sample, we could try to debug it and see if the issue is coming from our code or you set up.
regards,David Young
