@kirsan31 You have done a bit of work in conjunction with RDP. Have you run into this at all?

@manuz90flw This seems to be an issue with RDP. Did this work in a previous version of RDP for your product? My strong recommendation is that you check StackOverflow and answers.microsoft.com? This appears to happen for all versions of .NET Framework, so this is likely happening with the Common Controls as well. The question is whether we've always had this issue in all versions of RDP or if this is a new situation.

Hi @merriemcgaw ,

I think it's a issue with RDP. I did some other tests:

  1. VM with Windows 7 connect to windows server 2022 and I can replicate the issue KeyupWin7
  2. VM with Windows 8.1 connect to windows server 2022 and I can replicate the issue KeyupWin8
  3. Windows 10 connect to VM Windows 8.1 and I can replicate the issue
  4. Windows 10 connect to Windows server 2022 and I can replicate the issue with javascript KeyupWin10javascript

@manuz90flw The best advice I can give you at this point is to use the Windows feedback tool to file the feedback against RDP. That will allow you to engage directly with that product team and to provide any diagnostic data they might need. Unfortunately there isn't much for WinForms to do at this point, so I'm going to close this issue.
