title: Graphpaper Background with XAML and Path Markup Language
body: <p>for some hours im trying to create a graphpaper background for a ListView. For a better understanding I'll describe what I mean. I want to realise it with XAML.
  Until now I finished the little rectangles with 10px margin, but I need another grid, with bigger lines which have a margin of 100px and I don't really understand the Path Markup Language.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>    &lt;DrawingBrush x:Key="ListBackgroundBrush" Viewport="0,0,10,10" ViewportUnits="Absolute" TileMode="Tile"&gt;
      &lt;DrawingBrush.Drawing&gt;
          &lt;DrawingGroup&gt;
              &lt;!--  Linien alle 10 Pixel --&gt;
              &lt;GeometryDrawing Geometry="M0,0 L1,0 1,0.1, 0,0.1Z" Brush="#EAEAEA" /&gt;&lt;!-- Wagerecht--&gt;
              &lt;GeometryDrawing Geometry="M0,0 L0,1 0.1,1, 0.1,0Z" Brush="#EFEFEF" /&gt;&lt;!--  Senkrecht --&gt;
  
              &lt;!-- Linien alle 100 Pixel Senkrecht  --&gt;
              &lt;GeometryDrawing Geometry="M0,0 L1,0 1,0.2, 0,0.2Z" Brush="Red" /&gt;
              &lt;!-- Linien alle 100 Pixel Wagerecht --&gt;
              &lt;GeometryDrawing Geometry="M0,0 L1,0 1,0.2, 0,0.2Z" Brush="Green" /&gt;
          &lt;/DrawingGroup&gt;
      &lt;/DrawingBrush.Drawing&gt;
  &lt;/DrawingBrush&gt;    
  &lt;ControlTemplate TargetType="ListView"&gt;
                  &lt;Border CornerRadius="2" Background="{StaticResource ListBackgroundBrush}" BorderThickness="1,1,1,1" BorderBrush="#E1E1E1"  SnapsToDevicePixels="True"&gt;
  &lt;/ControlTemplate&gt;
  </code></pre>
  
  <p>Thats what I did until now, but I dont know how to modify the Geometry Parameters to make the margin between the lines bigger.</p>
  
  <p>I'll be happy about every answer!</p>
