Data source on the form idea originated from Borland Delphi. Later, Anders Hejlsberg quit Borland to work at Microsoft, where he implemented the idea of visual and non-visual components and property editors in .net

You would be even more impressed with Delphi, because after connecting your data source, your form fills with data at design-time. Lazarus and Typhon does the same.

Yes, I'm well-aware of the genesis. In my opinion, .NET + WinForms stack was a better Delphi.

And if I remember correctly, it could also do the "fill the form with data" trick.
