How to set border color of a WPF Button?

The BorderBrush property of the Button sets a brush to draw the border of a Button. You may use any brush to fill the border. The following code snippet uses a linear gradient brush to draw the border with a combination of red and blue color.

<Button.BorderBrush>

    <LinearGradientBrush StartPoint="0,0" EndPoint="1,1" >

        <GradientStop Color="Blue" Offset="0" />

        <GradientStop Color="Red" Offset="1.0" />

    </LinearGradientBrush>

</Button.BorderBrush>

 

The Background and Foreground properties of the Button set the background and foreground colors of a Button. You may use any brush to fill the border. The following code snippet uses linear gradient brushes to draw the background and foreground of a Button.

 

<Button.Background>

    <LinearGradientBrush StartPoint="0,0" EndPoint="1,1" >

        <GradientStop Color="Blue" Offset="0.1" />

        <GradientStop Color="Orange" Offset="0.25" />                   

        <GradientStop Color="Green" Offset="0.75" />

        <GradientStop Color="Red" Offset="1.0" />

    </LinearGradientBrush>

</Button.Background>

<Button.Foreground>

    <LinearGradientBrush StartPoint="0,0" EndPoint="1,1" >                   

        <GradientStop Color="Orange" Offset="0.25" />

        <GradientStop Color="Green" Offset="1.0" />                   

    </LinearGradientBrush>

</Button.Foreground>
