After the last release, one of our infragistics ultragrids in our vb.net program running the latest release of 2015.1 Winforms began having issues loading.
Thank you for your help in advance,
Derek
Below is the exception we receive on load:

HOw fix, it canges only when summaries column last right on group, you must insert blank Column on last right on group
Hi Hung,
Yes, the issue happens when you have groups and the last column has a summary. So if you insert a blank column the issue won’t happen. I have created a private case for you, so that you will be notified when the fix is released. The case number is CAS-166472-X8D1P6 and you can view it from the following link:
https://ko.infragistics.com/my-account/support-activity
Please let me know if you have any additional questions.
Is there a way to get the previous hotfix for 14.2? We were unaware of this issue, and went live with a build of our application over the weekend.
