<div dir="ltr"><div><div>Hi Fabio,<br><br></div>I'd like to share how i implemented similar behavior of TDbCtrlGrid, so maybe you can be interested. If not just ignore.<br><br></div><div>First i create a TFrame in Lazarus put the controls that i need to be there.<br>
<br></div><div>In the control i want to display the instances of the frame i create at runtime according to a configuration<br><br></div><div>This way i have the easy of use of Lazarus designer with a lot of flexibility.<br>
<br></div><div>I created an control (<a href="https://code.google.com/p/luipack/source/browse/trunk/luicontrols/jsonmediators.pas">https://code.google.com/p/luipack/source/browse/trunk/luicontrols/jsonmediators.pas</a> ) that does the above. The frame class (TJSONBooleanRadioButtonViewFrame) is hardcoded but it can be decoupled by using an interface.<br>
<br></div><div>To implement TDbCtrlGrid like control with this approach seems easier then you are trying:<br><br></div><div>- Define an interface with what you need to configure the DbCtrls like<br></div><div> IDbCtrlItem = interface<br>
</div><div> SetDatasource(Datasource: TDataSource);<br></div><div> end;<br></div><div>- Create a control that has a TFrameClass property<br></div><div>- When the TFrameClass is set, check if implements IDbCtrlItem<br></div>
<div>- At runtime create as many TFrameClass instances as needed configuring them at initialization through the IDbCtrlItem interface<br></div><div>- Bind to dataset events and update the controls accordingly<br></div><div>

</div>On second thought the LCL method is not very flexible.<br>
I added a general designer event.<br>
