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][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TRxDBGrid.SetAutoSort(const AValue: boolean);var  S: string;  Pos:
integer;begin  if FAutoSort = AValue then    exit;  FAutoSort :=
AValue;  if Assigned(DataSource) and Assigned(DataSource.DataSet) and 
  DataSource.DataSet.Active then  begin    S :=
DataSource.DataSet.ClassName;    if RxDBGridSortEngineList.Find(S,
Pos) then      FSortEngine := RxDBGridSortEngineList.Objects[Pos] as
TRxDBGridSortEngine    else      FSortEngine := nil;   
FSortColumns.Clear;  end;end;          
Has anyone used this and got it working?

Thanks
Dave
