Why not invent something specifically for ActiveControl instead?

[Lazarus] DB aware components
Hi Folks. Is it normal that when a TDBGrid is dropped onto a TFrame (or descendant) the DataSource property cannot be assigned to a TSqlQuery dropped onto a TDataModule ? In other words, in the properties inspectior of the TDBGrid, the Datasource property shows nothing. The TDataModule is in the uses clause of the TFrame Interface. Otherwise when the TDbGrid is doppêd onto a TForm, the DataSource shows all TDataset descendants dropped into the TDataModule. It appears to be the same for all data aware components that I have tested so far. Finally, assigning the datasource at runtime appears to work. But this is a workaround.

Re: [Lazarus] DB aware components
In the same way, travelling within a TFrame components doesn't work too. When clicking over any component on the TFrame using either TAB or any other arrow key has no effect. At runtime, it works.

Re: [Lazarus] DB aware components
Same for TImageList. A TImageList is dropped onto a TDataModule, included in the interface uses, but a TToolBar does not see the TImagesList in the TDataModule. This breaks completely the porting from Delphi. I'm really very disapponted. I've made another test as explained in the Wiki page http://wiki.freepascal.org/Frames - build a new TFrame - add the unit to the project units list (otherwise it is not droppable) - drop it onto a TTabSheet of a TPageCpntrol in the main form - drop a TSqlQuery onto the TFrame: this time, the objects in the TDataModule created before, are displayed in properties of the TFrame components (database for TSqlQuery, i.e.). It's a long way to ... This way does not allow to create independent TFrames and fill them with all pertinent components and code and that's exactly what I need. All the TFrames are independent and dynamically created as the user runs thru the application.
