  Hi
  
  In C1DataGrid,
  
  I successed in changing selected row after mouse left button DOWN
  
  but I can NOT change selected CELL after mouse left button DOWN (default is the selected cell will be changed when mouse left button UP)

  This is how I change selected row by MouseLeftButtonDown event
  
  [i]private void OnC1DataGridRowPreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
  
  {
  
  var rowPresenter = sender as DataGridRowPresenter;
  
  if (rowPresenter == null || dataGridView.SelectionMode != DataGridSelectionMode.SingleRow) return;

          dataGridView.SelectedIndex = rowPresenter.Row.Index;
      }[/i]
  

  Could you give me a way to solve this problem? Thank you so much!

  Hi,

  You could take help of GetCellFromPoint method in PreviewMouseLeftButtonDown event and assign the cell obtained to CurrentCell property, as follows:```
  
  var cell = _grid.GetCellFromPoint(e.GetPosition(_grid)) as C1.WPF.DataGrid.DataGridCell;
  
  _grid.CurrentCell = cell;

  Thanks,
  Ruchir
