title: Reusing a tooltip for several textboxes
body: <p>What should I write in the value of the Text property of the tooltip resource so it would show the text of each textblock dynamically ?</p>
  
  <pre><code> &lt;StackPanel x:Name="root"&gt;
      &lt;StackPanel.Resources&gt;
          &lt;ResourceDictionary&gt;
  
              &lt;ToolTip x:Key="tooltiptemplate"&gt;
                  &lt;TextBlock Background="LightBlue" TextTrimming="WordEllipsis" Text="?????"/&gt;
              &lt;/ToolTip&gt; 
  
          &lt;/ResourceDictionary&gt;
      &lt;/StackPanel.Resources&gt;
  
      &lt;TextBlock Text="Mickel" ToolTip="{StaticResource tooltiptemplate}"/&gt;
      &lt;TextBlock Text="Kim" ToolTip="{StaticResource tooltiptemplate}"/&gt;
      &lt;TextBlock Text="Jenny" ToolTip="{StaticResource tooltiptemplate}"/&gt;
  &lt;/StackPanel&gt;
