title: Lock element on the right
body: <p>I have two textboxes in my app, with a variable lenght. One is on the left, the other one on the right. By default their width is pretty little, 30 px. But as they contain a lot of numbers, the textbox on the left shifts the right one and enlarges the window (same thing when the right textbw contains too many numbers). To avoid this, I would like to stabilize the right textbox on the right, even if its width rises.</p>
  
  <p>I've tried to play with the columns size, but not.</p>
  
  <pre><code>&lt;Grid Grid.Row="2"&gt;
                              &lt;Grid.ColumnDefinitions&gt;
                                  &lt;ColumnDefinition Width="170" /&gt;
                                  &lt;ColumnDefinition Width="Auto" /&gt;
                                  &lt;ColumnDefinition Width="10" /&gt;
                                  &lt;ColumnDefinition Width="*" /&gt;                                    
                              &lt;/Grid.ColumnDefinitions&gt;
                              &lt;TextBox Grid.Column="1" MinWidth="30" Margin="0,0,0,0" Name="maxGmapWest" Text="{Binding Path=Options.MaxGmapWest, ElementName=Window, Mode=OneWay, Converter={StaticResource StringToDoubleConverter}}" PreviewTextInput="Tab1_PreviewTextInput" Width="auto" /&gt;
                              &lt;TextBox Grid.Column="3" MinWidth="30" Margin="230,0,0,0" Name="maxGmapEast" Text="{Binding Path=Options.MaxGmapEast, ElementName=Window, Mode=OneWay, Converter={StaticResource StringToDoubleConverter}}" PreviewTextInput="Tab1_PreviewTextInput" Width="auto" HorizontalAlignment="Left" /&gt;
                          &lt;/Grid&gt;
  </code></pre>
