This issue has the same behavior in .NET 6.0 & 7.0 & 8.0 and .Net Framework 4.8.

@Ashley-Li Are you working on this bug to fix it?

[dmitrii-drobotov]

It looks like this is related to native DateTimePicker control from Windows, and there is no way to change selected color from WinForms. I checked native DTP in an MFC app and it has the same issue:

@LeafShi1 , @SimonZhao888 , @Epica3055 - please take a look at this bug and investigation done by @dmitrii-drobotov , this is a good representative of external issues.

[merriemcgaw]

Yep, this is external to Windows and I will get it covered under the Common Controls exception.

[Ashutoshsahoo164]

Hi @merriemcgaw it under the exception right? is there any exception link i can refer?

[merriemcgaw]

I will work with the office hours to get a parent exception approved. Right now we're doing one-offs for every instance where Windows doesn't let us do something. I'd prefer not to have to file a new exception every time. When it's ready I'll provide a link.

@merriemcgaw thanks for above information. could you please help us with link through which we can track this issue.

[merriemcgaw]

The exception has already been filed.

WinForms is a thin wrapper around Win32 APIs. In this case it's the CommonControls (DateTimePicker). We have multiple exceptions for this code, and any time we file a bug on Windows it's automatically rejected as legacy UI. I want to get a blanked exception for all CommonControls in the cases where WinForms has no way to impact the situation. Same thing with CommonDialog APIs.

[merriemcgaw]

The exception is filed here (internal URL)

This particular issue we can't change, and it's not a very common scenario for our users.
