title: How to set tooltip for a ListviewItem
body: <p>I am using a <code>ListView</code> with a few fixed-size columns.</p>
  
  <p>The text in the rows may be too large to fit in the column, so I would like to make it so that when the user hovers over the <code>ListViewItem</code>, it shows a tooltip with more text.</p>
  
  <p>I tried setting the <code>ToolTipText</code> property of the <code>ListViewItem</code>:</p>
  
  <pre><code>ListViewItem iListView = new ListViewItem("add");
  
  iListView.ToolTipText = "Add Expanded";
  myListView.Items.Add(iListView);
  </code></pre>
  
  <p>Unfortunately, it didn't seem to work. How can I get <code>ListViewItems</code> to show ToolTips?</p>
