title: C# WPF DataGrid vertical scroll
body: <p>I see the following behavior with a WPF Datagrid.
  When there are more items then the height of the view area, the vertical scroll is available.
  When I click on the last row in the view, an automatic scroll occurs where the row that was just below the last comes into view.</p>
  
  <p>The first column of the datagrid is a checkbox.  When the user clicks on this last row, I'm not getting the event for checkbox clicks.  The checkboxes in all other rows work OK.</p>
  
  <p>I'd like to disable the automatic scroll, but can't figure how to do it.</p>
  
  <pre><code>&lt;Style x:Key="SingleClickEditing"  TargetType="{x:Type toolkit:DataGridCell}"&gt;
       &lt;EventSetter Event="CheckBox.Checked" Handler="OnChecked"/&gt;
       &lt;EventSetter Event="CheckBox.Unchecked" Handler="OnChecked"/&gt;
  &lt;/Style&gt;
  </code></pre>
