WPF Striped Gradient Code Behind VB

Posted on 2014-01-23

So I am trying to apply a striped gradient to a rectangle from the code behind.  I know how to do it from XAML:

<LinearGradientBrush StartPoint="0,0" EndPoint="1,1" SpreadMethod="Repeat">
    <GradientStop Offset="0" Color="DarkRed"/>
    <GradientStop Offset="0.5" Color="DarkRed"/>
    <GradientStop Offset="0.5" Color="Black"/>
    <GradientStop Offset="1" Color="Black"/>

 <LinearGradientBrush.RelativeTransform>
        <ScaleTransform ScaleX="0.01" ScaleY="0.01"/>
    </LinearGradientBrush.RelativeTransform>
</LinearGradientBrush>

Open in new window


But I can't figure out how go get the RelativeTransform to work.  Here is my vb:

 Dim myBrush As New LinearGradientBrush()
        myBrush.SpreadMethod = GradientSpreadMethod.Repeat
        myBrush.GradientStops.Add(New GradientStop(Colors.DarkRed, 0.0))
        myBrush.GradientStops.Add(New GradientStop(Colors.DarkRed, 0.5))
        myBrush.GradientStops.Add(New GradientStop(Colors.Black, 0.5))
        myBrush.GradientStops.Add(New GradientStop(Colors.Black, 1.0))
        myBrush.RelativeTransform = ScaleTransform.ScaleXProperty

        rect0.Fill = myBrush

Open in new window


Any help on this would be appreciated.

This did it:

   Dim myBrush As New LinearGradientBrush()

        myBrush.GradientStops.Add(New GradientStop(Colors.DarkRed, 0.0))
        myBrush.GradientStops.Add(New GradientStop(Colors.DarkRed, 0.5))
        myBrush.GradientStops.Add(New GradientStop(Colors.Black, 0.5))
        myBrush.GradientStops.Add(New GradientStop(Colors.Black, 1.0))
        'myBrush.RelativeTransform = ScaleTransform.ScaleXProperty
        Dim scale As New ScaleTransform(0.1, 0.1)
        myBrush.RelativeTransform = scale
        myBrush.SpreadMethod = GradientSpreadMethod.Repeat
        rect0.Fill = myBrush
