You need to register all controls that you need to load from RVF with

RegisterClasses:

RegisterClasses([TButton, TEdit]);

Do it before the first loading, for example, in the initialization section

of the main form's unit.

Unfortunately, this code cannot be executed inside OnDblClick.

When the caret is in cell, RichViewEdit creates a special child editor to

editing this cell.

Your code (specifically SelectCols and SelectRows method) destroys this

editor. And VCL does not like when the component that raised the event is

destroyed inside this event.

The solution is using PostMessage. If you need an example, I can create it.
