I am trying to achieve the following thing: use an svg image into a custom button.

In order to do this I created a Custom button:

public class MainButton : Button

{

 static MainButton()

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

public string Text
{
  get { return (string)GetValue(TextProperty); }
  set { SetValue(TextProperty, value); }
}

public static readonly DependencyProperty TextProperty =
 DependencyProperty.Register("Text", typeof(string), typeof(MainButton), new UIPropertyMetadata(""));


public object Image
{
  get { return (object)GetValue(ImageProperty); }
  set { SetValue(ImageProperty, value); }
}

public static readonly DependencyProperty ImageProperty =
  DependencyProperty.Register("Image", typeof(object), typeof(MainButton), new UIPropertyMetadata(""));

}

I took a svg file, opened it in inkscape and saved it as xaml file.

I opened Themes.xaml and added the created xaml image as a ControlTemplate

And the button style is:

Style TargetType="{x:Type local:MainButton}">

        <StackPanel Canvas.Top="12"
              Canvas.Left="0"
              Canvas.ZIndex="2"
              Width="80">

          <ContentControl x:Name="Img" Template="{StaticResource Home}" />

        </StackPanel>

        <StackPanel x:Name="spText" Canvas.Top="45"
                       Canvas.Left="1" 
                       Canvas.ZIndex="1"
                       Width="80">

            <TextBlock x:Name="Txt" Text="{Binding Path=(local:MainButton.Text),
                            RelativeSource ={RelativeSource FindAncestor,
                            AncestorType ={x:Type Button}}}"
                        VerticalAlignment="Center"
                        HorizontalAlignment="Center"
                        Foreground="White"
                        FontSize="14"/>
        </StackPanel>

...

As you can see I have hardcoded the StaticResource name

I want to be able to have a binding with property Image on this Template, something like

So that I can set the Image property of the button with the name of the StaticResource I want.

For example, having beside "Home" image, another one "Back" I would have two buttons in MainWindow declared like this:

Any advice is kindly taken. Thank you for your time.
