My form A will call another TCustomForm from a DLL and place it on a panel in the main program.
But when I do this my dbgrids don't behave like they should. I can't navigate with my up_key and down_key.

I know that if rewrite the code and shows the tcustomform in the dll as showmodal the dbgrids behave perfect.
How can I do this when the form is hooked to the panel in the mainform too?

In Main (where I call the form):

ShowDllIRForm(MainForm.Handle).ParentWindow := MainPanel.Handle;
ShowDllIRForm(MainForm.Handle).Show;


In DLL (returns the form):

function ShowDllIRForm(hApp: THandle): TCustomForm; stdcall;
begin
 Application.Handle := hApp;
  if not assigned(IRForm) then
    IRForm := TIRForm.Create(Application);
  result := IRForm;
end;
