You could determine is control TEdit using InheritsFrom() function of the
control. Then cast it to TEdit. Another way is used in Delphi - declare
class of type TControl and case to this type:
type
TControlAccess = class(TControl);
var
Control: TControl;
begin
Control := ...
TControlAccess(Control).Color := ...
end;
