Dialog/Form design doesn't match

StormyC — Wed, 20 May 2026 13:34:01 GMT

When using .NET8 / VS2022 and AutoCAD2025 the design for the form doesn't match with the form ultimately displayed in AutoCAD. Any clues?

I have tried WPF and WinForms, both the same.

.NET 8 introduces breaking changes in Windows forms sizing/scaling behavior.

Have a look at this document.

Prefer using WPF, layout and divide with Grid, and do not use mouse dragging to create interface elements.

Interesting - thanks. I did try to adjust some setting relating to DPI scaling but the issue appears to be: I created a new WPF Form and the Form controls are present within AutoCAD and not in the designer so this pushes everything down causing the last button to be clipped. If i add 40px to the bottom of the form it appears OK...

Ive used a fully defined grid now and added elements in .xaml as suggested. Seems to be working ok.

Thanks both for you inputs.

Finally found the fix for my particular issue it was a property on the form - this was "Font". Setting it to None makes the forms appear correct.
