title: How to change anchor pane background in AvalonDock?
body: <p>I have a simple .xaml file for my GUI:</p>
  
  <pre><code>&lt;Window x:Class="WpfApplication5.MainWindow"
          xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
          xmlns:xced="http://schemas.xceed.com/wpf/xaml/avalondock"
          Title="MainWindow" Height="350" Width="525"&gt;
      &lt;Grid&gt;
          &lt;xced:DockingManager Background="Gray"&gt;
              &lt;xced:LayoutRoot&gt;
                  &lt;xced:LayoutPanel&gt;
                      &lt;xced:LayoutAnchorablePane&gt;
                          &lt;xced:LayoutAnchorable&gt;
  
                          &lt;/xced:LayoutAnchorable&gt;
                      &lt;/xced:LayoutAnchorablePane&gt;
                  &lt;/xced:LayoutPanel&gt;
              &lt;/xced:LayoutRoot&gt;
          &lt;/xced:DockingManager&gt;        
      &lt;/Grid&gt;
  &lt;/Window&gt;
  </code></pre>
  
  <p>All I want to do is to change the background, and I can achieve this via the Background attribute, but it is not consistent with the anchor pane as shown in the picture:</p>

  <p>How can I also change that white to gray?</p>
