The following example shows how sort the view by column 'name' ascending. Sorting a column ascending is the default behavior, it needs not to be set explicitly:

  JamSystemShellView.SortBy := TShellColumns.Name;

The following example shows how sort the view by column 'name' descending:

  JamSystemShellView.SortBy := TShellColumns.Name;
  JamSystemShellView.SortDirection := sdDescending;
