QUESTION 1
You work as the Web developer at www.pass4sure.cc. You are developing an ASP.NET application which will be used on the intranet site of www.pass4sure.cc. All www.pass4sure.cc’s employees use Internet Explorer
on the company intranet.
Multiple controls that postback to the server for event processing are contained in a page named UserAccount.aspx. To complete processing, the event handlers of the controls require access to a database.
Whenever the UserAccount.aspx page executes a postback to the server, the browser window goes blank for a few moments while the page is being refreshed. The specific control which has the focus
before the postback was performed does not have the focus once the page is re-rendered. This tends to
be very confusing to users, and often results in users making invalid data entries.
You want to configure the UserAccount.aspx page so as to prevent the browser window from being blank after a postback. You also want to maintain the correct control focus once events are processed. You want to use the the minimum amount of development effort to accomplish these tasks.
How will you accomplish the task?

A. For controls that perform the postbacks, include the following attribute with the HTML code: RunAt=”client”
B. For controls that perform the postbacks, include the following attribute with the HTML code: EnableViewState=”True”
C. Insert the following attribute to the Page directive for the UserAccount.aspx page: SmartNavigation=”True”
D. Insert the following attribute to the OutputCache directive for the UserAccount.aspx page: Location=”client”

Answer: C

Explanation: When a page is requested by an Internet Explorer 5 browser, or later, smart navigation enhances the user’s experience of the page by performing the following:
• eliminating the flash caused by navigation.
• persisting the scroll position when moving from page to page.
• persisting element focus between navigations.
• retaining only the last page state in the browser’s history.
Smart navigation is best used with ASP.NET pages that require frequent postbacks but with visual content that does not change dramatically on return.
Reference: .NET Framework Class Library, Page.SmartNavigation Property [Visual Basic]

QUESTION 2
You work as the Web developer at www.pass4sure.cc. You have developed a financial application named PassGuide App01, which is written in Visual Basic .NET. PassGuide App01 consists of a page named AnnualFigures.aspx and a page class named AnnualFigures. AnnualFigures.aspx exists in the Finance namespace.
A www.Pass4sure.ccemployee named Andy Reid works as a developer in the IT department. One
morning you notice that FirstQuarter.aspx is not functioning correctly. You investigate the issue and find out that Andy has accidentally deleted the Page directive for FirstQuarter.aspx. You must create

a new Page directive to configure FirstQuarter.aspx to function correctly.
Choose the Page directive which you should use to accomplish the task.

A. <%@ Page Language="vb" Codebehind="AnnualFigures.aspx.vb" Inherits="AnnualFigures"%>
B. <%@ Page Language="vb" Codebehind="AnnualFigures.aspx.vb" ClassName="Finance.AnnualFigures"%> C. <%@ Page Language="vb" Codebehind="AnnualFigures.aspx.vb" Inherits="Finance.AnnualFigures"%>
D. <%@ Page Language="vb" Codebehind="AnnualFigures.aspx.vb" ClassName="Finance.AnnualFigures" Inherits="AnnualFigures"%>

Answer: C

Explanation: The Inherits attribute in the @ Page directive defines a code-behind class for the page to inherit. As AnnualFigures.aspx resides within the Finance namespace we should use Inherits=”Finance.AnnualFigures
Note: The @ Page directive defines page-specific (.aspx file) attributes used by the ASP.NET page parser and compiler.
Reference: .NET Framework General Reference, @ Page
Incorrect Answers
A: As AnnualFigures.aspx resides within the Finance namespace we should use
Inherits=”Finance.AnnualFigures
B, D: The ClassName attribute specifies the class name for the page that will by dynamically compiled automatically when the page is requested. We should not use ClassName here.

QUESTION 3
You work as the Web developer at www.pass4sure.cc. You develop an ASP.NET page named Enlist.aspx. Enlist.aspx will used by www.pass4sure.cc’s users to subscribe to www.pass4sure.cc’s e-mail lists.
The Enlist.aspx page contains an existing user control named ListEnlist. ListEnlist consists of two constituent controls, and is specified in the ListEnlist.ascx file. The TextBox control is named listNameText and the Button control is named enlistButton.
You want to include ListEnlist in the Enlist.aspx page. You do this by configuring this tag:

You now want the page to display the list name in ListNameLabel when a user subscribes to www.pass4sure.cc’s e-mail lists by providing a list name in listNameText, and then clicking the enlistButton.
Which two actions should you perform to achieve your goal in these circumstances? Choose two correct answers. Each answer presents only part of the complete solution?

A. Include this statement in the declaration section of ListEnlist.aspx:

Public listNameText As TextBox
B. Include this statement in the declaration section of Enlist.aspx: Public listNameText As TextBox
C. Include this statement in the Page.Load event handler for Enlist.aspx:
If Not Page.IsPostBack Then
listNameLabel.Text = ctlEnlist.listNameText.Text
End If
D. Include this statement in the Page.Load event handler for Enlist.aspx:
If Page.IsPostBack Then
listNameLabel.Text = ctlEnlist.listNameText.Text
End If
E. Include this statement in the Page.Load event handler for ListEnlist.ascx:
If Not Page.IsPostBack Then listNameLabel.Text = listNameText.Text End If
F. Include this statement in the Page.Load event handler for ListEnlist.ascx:
If Page.IsPostBack Then listNameLabel.Text = listNameText.Text End If
Answer: A, D Explanation:
A: We must expose the listNameText control by declaring it as public The ListEnlist.aspx file contains the listNameText control so we expose it in this file.
Note: The controls that make up a user control are called constituent controls. These controls are normally declared private, and thus cannot be accessed by the developer. If you want to make properties of these controls available to future users, you must expose them to the user.
D: If the control is reloaded in the Enlist.aspx file due to a response to a client postback we should set the listNameLabel.Text property.
Note: The UserControl.IsPostBack property gets a value indicating whether the user control is being loaded in response to a client postback, or if it is being loaded and accessed for the first time. Reference:
Visual Basic and Visual C# Concepts, Exposing Properties of Constituent Controls
.NET Framework Class Library, UserControl.IsPostBack Property
Incorrect Answers
B: The listNameText control is defined in ListEnlist.aspx, not in Enlist.aspx. C: This would only copy the text when the page is initially loaded.
E, F: We should use the Page.Load event of Enlist.aspx, not for ListEnlist.aspx.

QUESTION 4
You work as the Web developer at www.pass4sure.cc. You develop an ASP.NET page named Region.aspx. Region.aspx includes a Web user control named CountryList that contains countries in a drop-down
list box. The DropDownList control in CountryList.ascx is named CKCountry.
You want to configure a code segment for the Page.Load event handler for Region.aspx. You find though that you are unable to access CKCountry from code in Region.aspx.
