title: WPF set Grid row tooltip
body: <p>I have a Grid in which I have a RichTextBox control for the description text and there is a ToolTip attached with that RichTextBox. Please check the below code-</p>
  
  <pre><code>&lt;Grid Grid.Row="1" &gt;
           &lt;controls:RichTextBox Text="{Binding Description, Mode=TwoWay}" 
                VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" IsEnabled="False" /&gt;                          
  
           &lt;Grid.ToolTip&gt;
                 &lt;ToolTip&gt;
                    &lt;TextBlock Text="{Binding Path=Descriptiontext}"  
                           TextTrimming="CharacterEllipsis" TextWrapping="Wrap" /&gt;
                  &lt;/ToolTip&gt;
           &lt;/Grid.ToolTip&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>And I wanted to set "ToolTipService.ShowDuration" property for ToolTip. But I am not getting a way, where to attach it. </p>
  
  <p>Can anyone suggest how we can do that.</p>
