Can't set Foreground and Background colours for Checkbox

[johnt-star]

Describe the bug

Setting Foreground and Background properties have no effect on Checkbox.

Checkbox text colour remains white

This means checkboxes can;t be used on containers with white backgrounds.

Steps to reproduce the bug

1. Create a new project in VS using the Blank App (WinUI 3 in Desktop) template.
2. In MainWindow.xaml, replace the contents of StackPanel with the contents shown in screen grab below

Expected behavior

Foreground and Background properties should be customizable

Screenshots

Text remains white instead of black text on aliceblue background.

If container background is white then text is lost

You can change the resources : CheckBoxForegroundChecked, CheckBoxForegroundUnchecked, CheckBoxForegroundCheckedPointerOver, etc...

Thank you for your reply!

In my app, I am already statically setting the resources for the checkbox in a xaml file.

However, what I need is the ability to set Foreground and Background colours dynamically, from C#, based on user input.

Is there a way to do this, since the above CheckBox* properties used in the resource file are not exposed, or do I need to do some trickery in order to gain access to them?

Thanks in advance!

By code, a way can be by changing colors of elements in the Visual Tree
For example, for the Foreground, you can change the Foreground of the TextBlock (cb1 is the name of CheckBox) :

var tb = FindChildElement<TextBlock>(cb1);
tb.Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(255, 0, 0, 255));

FindChildElement can be found in MainWindow.xaml.cs (I had copied/translated it from MS samples)

Thanks again for your response.

I will look at your suggestion.

It would be nice if Microsoft provided consistent access to all the properties.

I don't think it is reasonable to think that some properties should be static and not accessible from code.

Hopefully, moving forward, the properties that can only be accessed in resource files are also accessible from C# code.
