WPF custom derived control style

Question

I have a custom control derived from Button:

    class MyControl : Button{}

And suppose, this class is empty (has no members).

In t

Answer 1

The TargetType property doesn't work for classes that derive from the specified type. See this question

Answer 2

I use SetResourceReference

SetResourceReference(StyleProperty, typeof(Button));

Answer 3

For doing this completely in code this answer on another forum works

this.Style = new Style(GetType(), this.FindResource(typeof(System.Windows.Controls.Button)) as Style);

Answer 4

Check if style for Button is there in your BureauBlue.xaml and remove x:key attribute from the style if it is there

Answer 5

You override the DefaultStyleKey's metadata in your static constructor:

static MyControl()
{
    DefaultStyleKeyProperty.OverrideMetadata(
        typeof(MyControl),
        new FrameworkPropertyMetadata(typeof(MyControl)));
}

Then, in your resources, you can base its style on the button:

<Style TargetType="{x:Type lcl:MyControl}" BasedOn="{StaticResource {x:Type Button}}" />

I've tried in the past to override the DefaultStyleKey's metadata to point to the base class (Button in your case), but it doesn't seem to work.
