procedure TForm1.wwDBGrid1TitleButtonClick(Sender: TObject;
AFieldName: String);
begin
ib_contact.IndexFieldNames:= AFieldName;
end;

I am copying a IP4 example that allows you order a column by clicking
on the title of the Grid. I am using IBO components (version G and
Ga), but the Grid just stops showing any information when you click
on it. The Grid is a detail grid in a Master-Detail relationship.

Any suggestions would be helpful.

Thank you in advance.
