DBGrid is empty in runtime

Hello,

I'm created a form with a DBgrid. In my datamodule I created the
needed Connection (TZConnection), Query (TZReadOnlyQuery) and
Datasource (TDataSource) to fill my DBgrid.
When I enable my datasource in designtime, I see the data in the grid.
So far so good.
But when running the program, I just see an empty grid.

Any idea what is going wrong here?

Thanks

Lainkes

Datasource.enabled does not operate as expected when set
programmatically. Set it enabled at design time, and run the program.
Then you may open/close Dataset or set TDBGrid visible or not.
