Check if FrameworkElement does have Border

I got a FrameworkElement within the eventhandler of a class. Is there a possibility to check if this FrameworkElement is an element that has a borderthickness/borderbrush property ?

Like

var element = myframeworkelement as IHasBorder;
element.borderthickness = new Thickness(1,2,3,4);

Does something like this exist ?

The properties BorderThickness and BorderBrush are defined in the Control class.

So you can try to cast your FrameworkElement to Control, and if that works, set the properties:

public partial class Window1 : Window
{
    public Window1()
    {
        InitializeComponent();

        var pnl = new StackPanel();
        this.Content = pnl;

        var button = new Button();
        button.Content = "Hi";

        pnl.Children.Add(button);

        SetBorder(button);
    }

    public void SetBorder(FrameworkElement fe)
    {
        var borderControl = fe as Control;

        if (borderControl != null)
        {
            borderControl.BorderThickness = new Thickness(10);
            borderControl.BorderBrush = Brushes.Red;
        }
    }
}
