Microsoft 70-515 : TS: Web Applications Development with Microsoft .NET Framework 4

You are developing a Web page.
The user types a credit card number into an input control named cc and clicks a button named submit.
The submit button sends the credit card number to the server.
A JavaScript library includes a CheckCreditCard function that returns a value of true if the credit card
appears to be valid, based on its checksum.
You need to ensure that the form cannot be used to submit invalid credit card numbers to the server.
What should you do?

• A. Configure the input control to run on the server. On the submit button, add a server-side OnClick handler that calls CheckCreditCard and rejects the form submission if the input is invalid.
• B. On the form, add an onSubmit handler that calls CheckCreditCard and cancels the form submission if the input is invalid.
• C. Configure the input control and the submit button to run on the server. Add a submit_OnClick handler that calls CheckCreditCard and rejects the form submission if the input is invalid.
• D. On the input control, add an onChange handler that calls CheckCreditCard and cancels the form submission when the input is invalid.

You create an ASP.NET page named TestPage.aspx that contains validation controls.
You need to verify that all input values submitted by the user have been validated by testing the
Page.IsValid property.
Which page event should add an event handler to?

• A. PreLoad
• B. Init
• C. PreInit
• D. Load

You create a Web page that contains drop-down menus that are defined by using div tags in the following code.
<div class="dropdown-menu"> <div class="menu-title">Menu One</div> <div class="menu-items" style="display:none;">
<div><a href="#">Item One</a></div>
<div><a href="#">Item Two</a></div>
</div> </div> <div class="dropdown-menu">
<div class="menu-title">Menu Two</div>
<div class="menu-items" style="display:none;">
<div><a href="#">Item Three</a></div>
<div><a href="#">Item Four</a></div>
</div> </div>
You need to write a JavaScript function that will enable the drop-down menus to activate when the user
positions the mouse over the menu title.
Which code segment should you use?

• A. $(".dropdown-menu").hover( function () {
  $(".menu-items", this).slideDown(100);
  },
  function () {
  $(".menu-items", this).slideUp(100);
  }
  );
• B. $(".dropdown-menu").hover( function () {
  $("this.menu-title",).slideDown(100);
  },
  function () {
  $("this.menu-title",).slideUp(100);
  }
  );
• C. $(".dropdown-menu").hover( function () {
  $(this)".slideDown(100);
  },
  function () {
  $(this).slideUp(100);
  }
  );
• D. $(".dropdown-menu").hover( function () {
  $(".menu-items").slideDown(100);
  },
  function () {
  $(".menu-items").slideUp(100);
  }
  );

Which control allows you to bind to data items that are returned from a data source and display them?

• A. Data Web Server Control
• B. DetailsView Web Server Control
• C. DataList Web Server Control
• D. ListView Web Server Control

You are developing an ASP.NET Web page that contains input controls, validation controls, and a button
named btnSubmit.
The page has the following code-behind. (Line numbers are included for reference only.)
01 public partial class _Default : System.Web.UI.Page
02 {
03 protected void SaveToDatabase()
04 {
05
06 }
07
08 protected void btnSubmit_Click(object sender, EventArgs e)
09 {
10
11 }
12 }
You need to ensure that all data that is submitted passes validation before the data is saved in a database. What should you do?

• A. Add the following method override.
  protected override void OnLoad(EventArgs e)
  {
  base.OnLoad(e);
  if (Page.IsValid) this.SaveToDatabase();
  }
• B. Add the following method override.
  protected override void OnPreRender(EventArgs e)
  {
  base.OnPreRender(e);
  if (Page.IsValid) this.SaveToDatabase();
  }
• C. Add the following method override.
  protected override void OnInit(EventArgs e)
  {
  base.OnInit(e);
  if (Page.IsValid) this.SaveToDatabase();
  }
• D. Add the following code segment at line 10.
  if (Page.IsValid) this.SaveToDatabase();
