How to select entire row on clicking the row header?

[Anton]

I want to select cells in grid and select rows on clicking on rows headers.
How to implement it? I've set up SelectionUnit="Cell". Now I need in selection rows on clicking on headers.

I need in the same functionality as in standard DataGrid (SelectionUnit="CellOrRowHeader").

Quick fix:

       private void RadGridView_PreviewMouseDown(object sender, MouseButtonEventArgs e)
        {
            var source = e.OriginalSource as DependencyObject;
            if(source == null)
                return;

            var cell = source.FindVisualParent<GridViewCell>();
            if(cell != null)
            {
                ((RadGridView)sender).SelectionUnit = GridViewSelectionUnit.Cell;
            }
            else
            {
                var row = source.FindVisualParent<GridViewRow>();
                if(row != null)
                {
                    ((RadGridView)sender).SelectionUnit = GridViewSelectionUnit.FullRow;
                }
            }
        }
