title: What is a simple way to set the background cell color for a CustomGrid?
body: <p>I've got:</p>
  
  <pre><code>&lt;CustomControl:GridControl ShowCustomGridLines="True" Grid.Column="2" Grid.Row="0"&gt;
              &lt;Grid.ColumnDefinitions&gt;
                  &lt;ColumnDefinition /&gt;
              &lt;/Grid.ColumnDefinitions&gt;
              &lt;Grid.RowDefinitions&gt;
                  &lt;RowDefinition /&gt;
                  &lt;RowDefinition /&gt;
              &lt;/Grid.RowDefinitions&gt;
          &lt;TextBlock Grid.Column="0" Grid.ColumnSpan="3" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center" Name="txbCaption" Text="{Binding Caption}" /&gt;
              &lt;CustomControl:GridControl ShowCustomGridLines="True" Grid.Column="2" Grid.Row="1"&gt;
                  &lt;Grid.ColumnDefinitions&gt;
                      &lt;ColumnDefinition /&gt;
                      &lt;ColumnDefinition /&gt;
                      &lt;ColumnDefinition /&gt;
                  &lt;/Grid.ColumnDefinitions&gt;
                  &lt;Grid.RowDefinitions&gt;
                      &lt;RowDefinition /&gt;
                  &lt;/Grid.RowDefinitions&gt;
                  &lt;TextBlock Grid.Column="0" Grid.Row="1" Text="П" HorizontalAlignment="Center" VerticalAlignment="Center" /&gt;
                  &lt;TextBlock Grid.Column="1" Grid.Row="1" Text="Ф" HorizontalAlignment="Center" VerticalAlignment="Center" Background="Yellow" /&gt;
                  &lt;TextBlock Grid.Column="2" Grid.Row="1" Text="%" HorizontalAlignment="Center" VerticalAlignment="Center" /&gt;
              &lt;/CustomControl:GridControl&gt;
  </code></pre>
  
  <p>I want to set the cell background of a TextBox (where Background="Yellow"). Setting the background for a TextBox doesn't help because I need to set the background color for the whole cell, even if there is no text. </p>
  
  <p>How can this be done?</p>
