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://es.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.

I cannot do that. I have to stay on .NET 2.0 / 3.5. The app is in use on many Windows XP PCs, and there is no way I can switch them all to .NET 4.0.

Hi,

As I already explained, we are not able to make changes in version 12.1, but what you could do in this case is to upgrade your current version (to .Net4.0) and also to upgrade all machines with Windows XP using the link below :

Let me know if you have any further questions.

Got it: you can't make the change. But, at least, provide me the patch so I can apply it on the source code I have already donwloaded, so I can build the control's library myself.

I don't want to get in details but it's not feasible to update the Windows XP PCs to .NET 4.0.

Thanks,

Emanuel

I ended up using Infragistics 2011.2, which does not present the bug.

IMHO it's a shame that the last version supporting .NET 2.0 - .NET 3.5 is left with a really nasty known bug. I have another application in use, based on CAB and SCSF for WinForms that uses 2012.1 version. The bug didn't occur yet, but I will be a big pain to fix it if it does.

Hello Emanuel,

I`m not able to do that (due to company policy) except in a case, if you are owner of product key for version 12.2 or higher. Do you have a key for version 12.2 or higher ? If so, you could find the fix in the source code of that version, but if you need assistance, please do not hesitate to write me.

Please take a look on section IV. Source Code of the license agreement
