Tôi đã tự tìm ra. Vì vậy, tôi sẽ trả lời câu hỏi của riêng tôi. Đây là mã mẫu:

[Code] 
const DB_PAGE_CAPTION='Select Application Database Folder'; 
    DB_PAGE_DESCRIPTION='Where should application database files be installed or where  your database files already are?'; 
    DB_PAGE_SUBCAPTION='In case of new installation select the folder in which Setup should install application database files, then click Next. Or select folder where previous version of application stored database files, then click Next'; 

var databasePage : TInputDirWizardPage;//this is predefined form declaration 
    CheckListBox : TNewCheckListBox; //this is new element i'm about to add to page 

procedure createDatabaseWizardPage; //creating page 
begin 
databasePage :=CreateInputDirPage(wpSelectDir, 
DB_PAGE_CAPTION, 
DB_PAGE_DESCRIPTION, 
DB_PAGE_SUBCAPTION, 
False, ''); 
databasePage.Add(''); 

databasePage.buttons[0].Top:=databasePage.buttons[0].Top+ScaleY(70);//moving predefined 
databasePage.edits[0].Top:=databasePage.edits[0].Top+ScaleY(70); //elements down. 
databasePage.edits[0].Text:=ExpandConstant('{commonappdata}\my app');//default value 

CheckListBox := TNewCheckListBox.Create(databasePage);//creating and modifying new checklistbox 
CheckListBox.Top := 40 + ScaleY(8); 
CheckListBox.Width := databasePage.SurfaceWidth; 
CheckListBox.Height := ScaleY(50); 
CheckListBox.BorderStyle := bsNone; 
CheckListBox.ParentColor := True; 
CheckListBox.MinItemHeight := WizardForm.TasksList.MinItemHeight; 
CheckListBox.ShowLines := False; 
CheckListBox.WantTabs := True; 
CheckListBox.Parent := databasePage.Surface;//setting control's parent element 
CheckListBox.AddRadioButton('New Installation', '', 0, True, True, nil); 
CheckListBox.AddRadioButton('Update existing copy', '', 0, False, True, nil); 
end; 


procedure InitializeWizard; 
begin 
createDatabaseWizardPage(); 
end; 

Xin cảm ơn tất cả mọi người! :-)
