>I did this exactly already. But, it seems like grid's child Init method executes before grid Init method itself. So, this approach doesn't work, because, as I said, all columns are defined in design-time, I mean, each column has ControlSource property set in design-time. Threfore, if my form received the table with different structure, one of column Init method failed, I assume. I traced in the debug: it successfully goes through Load method, then immediately stops. At this point Grid.Init method isn't even executed.

Is there any way for you to write in such a way as to have the controlsources set programmtically? For example, in the framework I use (VMP) there is a method called from thr Grid Init that sets the controlsources for all the columns. If you did it this way, then the Grid could return .F. and not initialize. If it passed your test, then the default behavior would be to call the new method.

Just an idea.
