title: How can you turn on word wrapping for all tool tips in Silverlight 4?
body: <p>In my Silverlight 4 application I have some long tooltips. By default these tooltips appear one one very long line. For example:</p>
  
  <pre><code>        &lt;TextBox Text="Test1" 
          ToolTipService.ToolTip="One tasdg asdg as da sdg asdg  asdg  asdg  asd gas dg a sdg a sdg a sd  a sd g asdasdgasdg    sadgasdgasdg  asdg  asdg  asd   as  a sd g a sdg      asd g asd g asd g asdgasdg     asdgasdg"/&gt;
  </code></pre>
  
  <p>What I would like to do is to make the tooltips wrap around to appear on multiple lines. One way of achieving this is to define the tooltip using a TextBlock. For example:</p>
  
  <pre><code>        &lt;TextBox Text="Test2"&gt; 
          &lt;ToolTipService.ToolTip&gt;
              &lt;TextBlock TextWrapping="Wrap" Width="200" Text="One tasdg asdg as da sdg asdg  asdg  asdg  asd gas dg a sdg a sdg a sd  a sd g asdasdgasdg    sadgasdgasdg  asdg  asdg  asd   as  a sd g a sdg      asd g asd g asd g asdgasdg     asdgasdg"/&gt;             
          &lt;/ToolTipService.ToolTip&gt;
      &lt;/TextBox&gt;
  </code></pre>
  
  <p>Having to do this for every control that I want to define a tooltip seems like a lot of extra work. Ideally what I would like to do is to define the tooltips as strings like the first example, and then have a style globally applied to all ToolTips, which would make the tooltips wrap around. So in my App.xaml, I would define something like this:</p>
  
  <pre><code>        &lt;Style TargetType="ToolTip"&gt;
          &lt;!-- Somehow make all tooltips wrap at a width of 200 --&gt;
      &lt;/Style&gt;
  </code></pre>
  
  <p>Any advice on how I might go about doing this?</p>
