DBGrid DataSource JsonDataSet, DBGrid can't show data.

Zvoni, jesusr,

Your sarcasms are unfair, bird00101011 is using a lazarus Wiki example, so I imagine, is learning lazarus and FPC.

In the Wiki explanation, there is no mention of binding the OnCreate in the form object inspector to procedure TForm1.FormCreate(Sender: TObject); maybe the Wiki could be improved ...

As I wrote above he managed to supply a compilable project for testing.

Then he should have read the Wiki on HOW TO USE Lazarus FIRST: https://wiki.lazarus.freepascal.org/Howdy_World_(Hello_World_on_steroids)
There you have the explanation how to bind Events to procedures.

"Copy/Paste"-ers don't get any pity from me

And, since i stated he doesn't seem to be a rookie (DB with JSON), he probably did already some coding in other languages and/or IDE's, and there he would have had the same "problem"

More useful link is https://wiki.lazarus.freepascal.org/Howdy_World_(Hello_World_on_steroids), you link is incomplete.

In that page there is not once the mention of F11 to pop up the object inspector when a form is displayed, just suggestion to go thru the menu ..., F12 is mentionned many times.

As per stupidly copy pasting, that's something I do all the time to see what things have in the stomach.

First things I did when OP posted the project were :

• Extract project and load in lazarus
• Compile / run and see that the grid is not filled up as per OP complaint.
• Put break point in FormCreate and run
• See that code is not called -> check form in OI -> problem solved

Total time, few minutes, thanks to the compilable project.
