I have a net 7 Win Forms project using Ultimate UI, in particular UltraWinTabControl and some editors. It works ok. Currently I try to convert it to the recently released .net 8and I have some issues with controls: tab headers don't react to mouse clicks, buttons don't react to clicks etc.All other dependencies compatible with net 7 work ok with net 8.Are ultimate UI assemblies supposed to be compatible with net 8? If not, are there plans to upgrade? Even some beta version would be ok for the time being.Thanks!Artem Kliatchkine
Hello Artem,
Thank you for your post. In order to understand the nature of the issue i set up a .net 8 sample for UltraTab and UltraButton and included packages V23.1.52 ,.When i run the sample click events are working fine for me .
Here is the screenshot for the reference. also attached my demo sample.
May be modify my sample help me reproduce the issue for further investigation.

Hello Divya,Thank you for your answer. Indeed in ytour case it seems to work in net 8, that gives hope.The code I'm working with is rather complex and extracting a clean example is not easy.Just as an extra info, when I start it in .net 8 I see this internal exception:System.InvalidOperationException: 'Type 'Infragistics.Win.AccessibleObjectWrapper+UltraAccessibleObject' has a ComVisible(false) parent 'System.Windows.Forms.AccessibleObject' in its hierarchy, therefore QueryInterface calls for IDispatch or class interfaces are disallowed.'with this call stack:It doesn't happen when the same code is built in net 7.Of course it can also be something wrong on my side.
So here is thing ,our packages are not updated yet to fully support .net8 , we are working on release packages for .net 8 and would be available sometime with upcoming release.
But meantime if we are finding any error we are trying to log it into our internal bug tracking system so that we can test the same scenario with the .net 8 when it is release.
So here are two options for you either wait for the .net 8 release or isolate your sample and try to find what exactly causing the issue. The error message you provided , I checked and we do have rowaccessibleobject class, check if any member of this class is causing the issue.
I don’t think the issue is from your side ,if everything is working with .net7 then it should be working on .net8 also its just we have to investigate and update our packages based on Microsoft update.
