title: How to display tooltip/pop-up of all data from database in datagrid in WPF MVVM C#
body: <p>I have a datagrid on my usercontrol. Call it Students
  And I have a database that pulls student information from a table, called Students.</p>
  
  <p>In this table, there is:</p>
  
  <pre><code>ID int
  Name varchar
  Class varchar
  Age int
  Sport varchar
  House varchar
  </code></pre>
  
  <p>now in the datagrid, the Name, Class and Age are displayed. How would i make a pop-up or tooltip display the other data (House and Sport) when the mouse is hovering over a row?</p>
  
  <p>I am using MVVM principles, so no code behind. I know how to display data in MVVM standards, I just don't know how it would be that it displays the data for that specific row.</p>
  
  <p>Example: if I have row - Mike, Class A, 13, how do I hover over Mike and display the Sport and House for him?</p>
  
  <p>And would it be easier to use a pop-up:</p>
  
  <pre><code>&lt;Popup Name="myPopup"&gt;
  &lt;TextBlock Text={Binding DataStud}&gt;
  
  &lt;/TextBlock&gt;
  &lt;/Popup&gt;
  </code></pre>
  
  <p>or a tooltip in the datagrid:</p>
  
  <pre><code>&lt;my:DataGrid ToolTip="{Binding ToolTipDisp}"&gt;
  </code></pre>
  
  <p>or, is it a row specific deal in the datagrid?</p>
