title: Disable tabstop between columns in a WPF datagrid
body: <p>I have a WPF Toolkit datagrid with mulitple columns. I am trying to get a behaviour where you can tab into the grid using tab, then tab out again using a single tab. E.g. I do not want to tab through all the columns or cells of the grid, just once in, and once out.</p>
  
  <p>Is there a simple solution, I have tried setting the TabNavigation to Once, along with disabling TabStop (not shown in code below) and setting TabNavigation on the columns to None, but without success.</p>
  
  <p>Is there something I am missing or do I need to handle the Tab-key in code?</p>
  
  <pre><code>        &lt;my:DataGrid Name="datagrid"
                       AutoGenerateColumns="False" IsReadOnly="True"
                       CanUserAddRows="False" CanUserDeleteRows="False"
                       Background="White"
                       KeyboardNavigation.TabNavigation="Once"&gt;
              &lt;my:DataGrid.Columns&gt;
                  &lt;my:DataGridTextColumn x:Name="ID" Header="ID" Width="1*" &gt;&lt;/my:DataGridTextColumn&gt;
                  &lt;my:DataGridTextColumn x:Name="Ticker" Header="Ticker" Width="1*" KeyboardNavigation.TabNavigation="None"&gt;&lt;/my:DataGridTextColumn&gt;
                  &lt;my:DataGridTextColumn x:Name="OfficialName" Header="Name" Width="3*" KeyboardNavigation.TabNavigation="None"&gt;&lt;/my:DataGridTextColumn&gt;
              &lt;/my:DataGrid.Columns&gt;
          &lt;/my:DataGrid&gt;
  </code></pre>
