I recently received a support ticket from a user who was encountering a script error while working with the UltraWebGrid in one of our older applications. The application is a WinForms application that among other things is using a WebBrower control to display a web page that the user edits. Prior to the user's machine upgrade where she was using Windows XP and IE8, the page did not report an error, however since upgrading to Windows 7 and IE9 the user encounters an error trying to update a column in the UltraWebGrid.
The error the user is receiving is as follows: Line: 11238Char: 2Error: Unable to get value of the property 'init': object is null or undefined
Do you want to continue running scripts on this page? On top of that once the error occurs, clicking the Yes or No dialog simply prompts with the dialog forcing one to go to the Task Manager and kill the application.
I've taken a look at the application to see which version of Infragistics UltraWebGrid the application (Web form) is using and it is as follows:<%@ Register assembly="Infragistics2.Web.v8.3, Version=8.3.20083.1009, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.Web.UI.GridControls" tagprefix="ig" %><%@ Register assembly="Infragistics2.WebUI.UltraWebGrid.v8.3, Version=8.3.20083.1009, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.WebUI.UltraWebGrid" tagprefix="igtbl" %>
Also I looked up the issue on these forms and found this entry stating that the issue is an IE9 bug that Infragistics was supposed to be patching at some point, however I don't know what the progress is on that effort. The article also seems to infer replacing the UltraWebGrid with a new version, however to us that really isn't an option. We need a patch fix. Here is the Forum URL:

Are there any immediate solutions (patch fixes) out there that will resolve this issue?
We are also facing similar issues using UltraWebGrid with 10.2 version on IE9 compatibility mode. I believe the fix is in 10.3 onwards. So can you please confirm if the only way to fix is to get latest version of UltraWebGrid, or is there any other solution.
I understand migrating to WebDataGrid may solve these kind of issues, but that is not an option right now.
Thanks a lot.
Hi Paul,
I'm just following up to see if you have resolved your issue.
Hello Paul,
There are known issues of UltraWebGrid under IE9 and they are fixed in NetAdvantage release v10.3.2217 and later. So I would suggest you to upgrade your product. Also, please note that your version is outdated and no longer supported as you can see in the product lifecycle page - http://ko.infragistics.com/help/product-lifecycle/.
If you have any further questions, please feel free to contact me.
