It should inherrit everything from TWebStringgrid but
result := WebDBGrid.Cells[col,row] do not work so how to do it
It should work. What exact problem are you experiencing?
When I retest this in demo \Demo\Basics\DBGrid with code added
procedure TForm1.WebButton1Click(Sender: TObject);
begin
showmessage(webdbgrid1.cells[1,webdbgrid1.Row]);
end;
this shows the expected value.
It was an oversight for LSP but this code will compile & work.
We'll look to overcome this LSP limitation.
