title: How to get row's and cell's index of a just edited cell in DataGrid
body: <p>I'm having problem with finding row's and cell's index of a just edited cell in <code>DataGrid</code>.
  I'm using <code>CellEditEnding</code> event to know when the cell has been edited.</p>
  
  <p>Till now I've managed to do something like this. <code>Col1</code> contains property <code>DisplayIndex</code> and that is index of selected column but I can't find in the same way.</p>
  
  <pre><code>    private void DataGridData_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
      {
          DataGridColumn col1 = e.Column;
          DataGridRow row1 = e.Row;
      }
  </code></pre>
