The DefaultStyleKey property in WPF is used to specify the key that should be used to retrieve the default style for a control. The default style for a control is defined in a resource dictionary and can be customized to change the appearance of the control.
To set the Foreground property of a control's default style using the DefaultStyleKey, you can define a new style for the control in the resource dictionary with a key that matches the control's DefaultStyleKey property. For example, to change the Foreground property of all Button controls, you can define a new style in the resource dictionary with a key of "Button". Within the style, you can set the Foreground property to the desired color.
Here is an example of how to set the Foreground property of a Button control's default style using the DefaultStyleKey:
```xml
<!-- Define a new style for the Button control with a key of "Button" -->
<Style TargetType="Button" x:Key="Button">
<!-- Set the Foreground property to the desired color -->
<Setter Property="Foreground" Value="Red" />
<!-- Add any other customizations to the style -->
</Style>
```
Once you have defined the new style in the resource dictionary, you can apply it to all Button controls by setting the Style property of the control to the key of the new style:
```xml
<Button Content="Click me" Style="{StaticResource Button}" />
```
This will display the Button text in red, as specified by the Foreground property in the default style.
