title: How to make tooltip on hovering mouse over a button
body: <p>I am c# silverlight(5) beginner and not a bit know about how to make tool tip. In fact i couldnt find any option in toolbox for tool tip.</p>
  
  <p>What i have to do is to show a tooltip when mouse hover a button. Suppose if i have button like this :</p>
  
  <pre><code>&lt;Button Content="{Binding Path=Id}"
          Command="{Binding DataContext.ShowPopupCommand,
                     RelativeSource={RelativeSource AncestorType=data:DataGrid}}"/&gt;
  </code></pre>
  
  <p>Now how to create a ToolTip on this button in ViewModel.cs class ?</p>
  
  <p>Could someone please give me guidance on how to create ToolTip in c# silverlight application using MVVM approach. Any piece of code for help is really appreciated. Would be a great help. Thanks.</p>
