Hello again I have to support programically custom TDBGrid and TcxGridSite. I added mapping to the BorlandControls/DBGrid for custom DBGrid and to the Developer Express Controls/QuantumGrid/Site...
Derived or not it doesn't work. I'm sure the classname is correct. I've triple checked it. I just tried to use ClickColumnHeader on my DBGrid, its says in log that "an error occured".
