Microsoft TS: Web Applications Development with Microsoft .NET Framework 4 Sample Questions:

1. You create a custom server control named Task that contains the following code segment. (Line numbers are included for reference only.)
01 namespace DevControls
02 {
03 public class Task : WebControl
04 {
05 [DefaultValue("")]
06 public string Title { ... }
07
08 protected override void RenderContents(HtmlTextWriter output)
09 {
10 output.Write(Title);
11 }
12 }
13 }
You need to ensure that adding a Task control from the Toolbox creates markup in the following format.
<Dev:Task ID="Task1" runat="server" Title="New Task" />
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Insert the following code segment immediately before line 03.
[ToolboxData("<{0}:Task runat=\"server\" Title=\"New Task\" />")]
B) Add the following code segment to the project's AssemblyInfo.cs file.
[assembly: TagPrefix("DevControls", "Dev")]
C) Replace line 05 with the following code segment.
[DefaultValue("New Task")]
D) Replace line 10 with the following code segment.
output.Write("<Dev:Task runat=\"server\" Title=\"New Task\" />");

2. You are developing an ASP.NET web page named WebPage.aspx.
The page includes a user control named UserInfoControl.ascx.
You need to expose a control property named FirstName and read its value from the page.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Add the following code segment to UserInfoControl.ascx.cs: protected string FirstName { get; set; }
B) Add the following code segment to WebPage.aspx.cs: var firstName = UserInfoControl1.Attributes["FirstName"];
C) Add the following code segment to UserInfoControl.ascx.cs: public string FirstName { get; set; }
D) Add the following code segment to WebPage.aspx.cs: var firstName = UserInfoControl1.FirstName;

3. You create a Web page that contains the following code.
<script type="text/javascript">
var lastId = 0; </script> <div class="File">
Choose a file to upload:
<input id="File0" name="File0" type="file" /> </div> <input id="AddFile" type="button" value="Add a File" /> <input id="Submit" type="submit" value="Upload" />
You need to provide the following implementation.
Each time the AddFile button is clicked, a new div element is created.
The new div element is appended after the other file upload div elements and before the AddFile span.
Each new element has a unique identifier.
Which code segment should you use?

A) $("#AddFile").click(function () { var id = "File" + ++lastId; var item = $(".File:first").clone(true); $("input:file", item).attr({ id: id, name: id }); item.insertAfter("input[type=file]");
});
B) $("#AddFile").click(function () {
var id = "File" + ++lastId;
});
C) $("#AddFile").click(function () { var id = "File" + ++lastId; $(".File:first").clone(true).attr({ id: id, name: id }).insertBefore
("#AddFile");
});
D) $("#AddFile").click(function () { var id = "File" + ++lastId; var item = $(".File:first").clone(true); $("input:file", item).attr({ id: id, name: id }); item.insertBefore("#AddFile");
});

4. You are developing an ASP.NET Web application.
The application is configured to use the membership and role providers.
