XAML:

CODE-BEHIND:

//
// SINGLE CLICK EDITING

private void DataGridCell_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    DataGridCell cell = sender as DataGridCell;
    if (cell != null && !cell.IsEditing && !cell.IsReadOnly)
    {
        if (!cell.IsFocused)
        {
            cell.Focus();
        }
        DataGrid dataGrid = FindVisualParent(cell);
        if (dataGrid != null)
        {
            if (dataGrid.SelectionUnit != DataGridSelectionUnit.FullRow)
            {
                if (!cell.IsSelected)
                    cell.IsSelected = true;
            }
            else
            {
                DataGridRow row = FindVisualParent(cell);
                if (row != null && !row.IsSelected)
                {
                    row.IsSelected = true;
                }
            }
        }
    }
}

static T FindVisualParent(UIElement element) where T : UIElement
{
    UIElement parent = element;
    while (parent != null)
    {
        T correctlyTyped = parent as T;

        parent = VisualTreeHelper.GetParent(parent) as UIElement;
