Whats the minimum I have to do to descend a new control from TCustomGrid, and get it on a form in the IDE without getting ‘Abstract Error’ within the IDE?

I have tried everything for days, but Im a bit of a delphi noob atm, zero percent success with TCustomGrid 🙁

If someone could help me out just getting a basic descendant of TCustomGrid which does nothing but implement the base TCustomGrid behavious it would be much a appreciated. Thanks.

Edit – I know how to do the basics of creating controls, I just cant do it with TCustomGrid

    “Abstract Error” usually means that there are virtual abstract functions you’ll have to implement to make the class work. For TCustomGrid, this should be the DrawCell method, as you can see here.

    For a complete detailed example on how to build an own grid based on TCustomGrid, see this tutorial.
