Inno Setup remove/hide/disable the NextButton on a custom wizard page - inno-setup

Question

I would like to disable the "Next" button from my custom wizard page.
The fact is that I've no issue to change the caption of it for example, but if I set the NextButton.Enabled to False, Inno Setup show me the Welcome page instead of my Custom Page. Any Idea?
procedure CurPageChanged(CurPageID: Integer);
begin
WizardForm.NextButton.Caption := 'test'; { Works }
WizardForm.NextButton.Enabled := false ; { delete my custom page }
WizardForm.CancelButton.Caption := 'Finish';
end;
procedure CreateTheWizardPages;
var
Page: TWizardPage;
TestConnectivityButton: TButton;
begin
Page := CreateCustomPage(wpWelcome, 'Connectivity Test', '');
CurPageChanged(Page.ID);
TestConnectivityButton := TButton.Create(Page);
TestConnectivityButton.Width := ScaleX(100);
TestConnectivityButton.Height := ScaleY(30);
TestConnectivityButton.Caption := CustomMessage('TestConnectivityAccessButtonLabel');
TestConnectivityButton.OnClick := #TestConnectivityWindow;
TestConnectivityButton.Parent := Page.Surface;
end;
procedure InitializeWizard;
begin
CreateTheWizardPages;
end;

Answer 1

You have to make the changes, when you enter your custom page only – When CurPageChanged event function is called with CurPageID equal to Page.ID.
And you cannot call CurPageChanged yourself!
var
Page: TWizardPage;
procedure CurPageChanged(CurPageID: Integer);
begin
if CurPageID = Page.ID then
begin
WizardForm.NextButton.Caption := 'Test';
WizardForm.NextButton.Enabled := False ;
WizardForm.CancelButton.Caption := 'Finish';
end;
end;
procedure CreateTheWizardPages;
var
TestConnectivityButton: TButton;
begin
Page := CreateCustomPage(wpWelcome, 'Connectivity Test', '');
TestConnectivityButton := TButton.Create(Page);
TestConnectivityButton.Width := ScaleX(100);
TestConnectivityButton.Height := ScaleY(30);
TestConnectivityButton.Caption :=
CustomMessage('TestConnectivityAccessButtonLabel');
TestConnectivityButton.OnClick := #TestConnectivityWindow;
TestConnectivityButton.Parent := Page.Surface;
end;
Another option is using Page.OnActivate event instead of CurPageChanged event function.
