RxDBGrid Sort Question

[daveinhull]

Hi,

I'm trying to use the sort feature of the RxDBGrid, but it just keeps crashing.
When I look at the code it appears that the SortEngine is Nil, but I'm not sure how to set it up.

Code: Pascal  [Select][+][-]

1. procedure TRxDBGrid.SetAutoSort(const AValue: boolean);
2. var
3.   S: string;
4.   Pos: integer;
5. begin
6.   if FAutoSort = AValue then
7.     exit;
8.   FAutoSort := AValue;
9.   if Assigned(DataSource) and Assigned(DataSource.DataSet) and
10.     DataSource.DataSet.Active then
11.   begin
12.     S := DataSource.DataSet.ClassName;
13.     if RxDBGridSortEngineList.Find(S, Pos) then
14.       FSortEngine := RxDBGridSortEngineList.Objects[Pos] as TRxDBGridSortEngine
15.     else
16.       FSortEngine := nil;
17.     FSortColumns.Clear;
18.   end;
19. end;          

Has anyone used this and got it working?

Thanks
Dave
