title: Setting the background color on a Silverlight grid and still being able to edit it
body: <p>The first column below works perfectly except I can't set the background color. The second column has the background color working most of the way except when using the arrow keys to move around in the grid, the cell isn't visually changing. What is the easiest way to just change the gosh darn background color on a text column? Extra points if there is a way to do it without going into the template column and exploding the lines of code so much.</p>
  
  <pre><code>                    &lt;data:DataGridTextColumn
                          Header="Rank ST" 
                          Binding="{Binding Path=ShortTermRank}" 
                          IsReadOnly="False"
                      /&gt;
  
                      &lt;data:DataGridTemplateColumn Header="Rank LT"&gt;
                          &lt;data:DataGridTemplateColumn.CellTemplate&gt;
                              &lt;DataTemplate&gt;
                                  &lt;Border Background="Cornsilk"&gt;
                                      &lt;TextBlock Text="{Binding Path=LongTermRank}" Margin="4" /&gt;
                                  &lt;/Border&gt;
                              &lt;/DataTemplate&gt;
