Description

.NET version

All. Unfortunately.

Did it work in .NET Framework?

No. Unfortunately.

Did it work in any of the earlier releases of .NET Core or .NET 5+?

No.

Issue description

When the GroupBox is inheriting its ForeColor by its Parent control, the color is not correctly applied.

Steps to reproduce

  • Create a new WinForms Form.
  • Insert a TableLayoutPanel
  • Insert a GroupBox
  • Change the Backcolor of the Form to 32,32,32
  • Change the ForeColor of the Form to 240,240,240

The GroupBox should render the Text in light on dark background, but only the Frame is light. The text gets rendered in the original color:

@Olina, can you test, if this is a Framework regression? Thanks!

Contributor guide

Research direction
Investigate how GroupBox handles the ambient ForeColor property from its parent. Trace the rendering code for the text to ensure it uses the inherited ForeColor instead of the default color.
