title: Click event for DataGridCheckBoxColumn
body: <p>I have a <code>DataGrid</code> in a WPF form with a <code>DataGridCheckBoxColumn</code>, but I did not find any click event, Checked and unchecked for it...</p>
  
  <p>Are these events available for the <code>DataGridCheckBoxColumn</code>? If not please suggest some workaround I could use.</p>
