Keyboard focus to DataGrid

Question

I have a WPF DataGrid and want to set the focus to the first item so that the user can navigate with the keyboard in the list of items, when the dialogue is opened the first

Answer 1

Ok, I found a solution. This works for me

Keyboard.Focus (GetDataGridCell (dataGridFiles.SelectedCells[0]));

private System.Windows.Controls.DataGridCell GetDataGridCell (System.Windows.Controls.DataGridCellInfo cellInfo)
{
  var cellContent = cellInfo.Column.GetCellContent (cellInfo.Item);

  if (cellContent != null)
    return ((System.Windows.Controls.DataGridCell) cellContent.Parent);

  return (null);
}

Now, I got the right focus and can navigate with keyboard.
