Description Roland Kossow 2017-02-10 19:51:40 EST 
As soon as I open a dataset that is associated with a TeeGrid I receive an assertion error that Seletced Row < 0 ...

procedure TGridSelection.SetRow(const Value: Integer);
begin
  if Row<>Value then
  begin
    Assert(Value>=0,'Error: Selected Row < 0');

    DoChangeRow(Value);

    ResetRange;

    DoChanged;
  end;
end;

I've fixed this. The assertion is wrong (it should check against < -1 , not < 0).

"-1" means no row is selected (no cell gets selected at all).

Workaround is to compile with assertions off compiler option.

I'm very close to release a "nightly build v1.01" with this and many more fixes, I'll notify you when its available.
