We have an old WinForms app with a .NET Advantage 2009 UltraWinGrid control. The default sort column was specified in the Design view, but now we have a requirement to save the user's sort order and restore it when relaunching the app.

We can get the last sort order in the Form_Close event with:

var gridSort = _ourGrid.DisplayLayout.Bands[0].SortedColumns[0];
SettingsFile.Save(gridSort.Key, (int)gridSort.SortIndicator);

And the correct values are stored in the Settings file, but nothing seems to restore the sort order to the grid. We have tried code like:

string columnName;
SortIndicator columnSort;
SettingsFile.Load(out columnName, out (int)columnSort);

var ourGridSort = _ourGrid.DisplayLayout.Bands[0].SortedColumns;
ourGridSort.Clear();
ourGridSort.Add(columnName, columnSort);
_ourGrid.DisplayLayout.Bands[0].SortedColumns.RefreshSort(true);

In the Form_Load, but this has no effect on the grid, it remains sorted by the original default.
