The bug presented in http://ko.infragistics.com/community/forums/p/80433/406341.aspx is still present. See attached sample.
I have to use CLR 3.5. The application cannot be upgraded.
Hello Ehaisiuc,
You are right. The issue exist in version 12.1, because the mentioned fix is include in WinForms_2013.2, WinForms_2013.1, WinForms_2012.2. (take a look on the latest information in that forum thread)
Please upgrade to one of our latest version where the issue is fixed. The product lifecycle of your version is expired. More details you could find on http://ko.infragistics.com/help/product-lifecycle/. It mean that we are not able to make any changes in version 12.1
Let me know if you have any questions.
