<asp:ListBox ID="lb1"AutoPostBack="true" runat="server" />

The page contains a code-behind file. The code below is written in the file:

Private Sub BindData(ByVal sender As Object, ByVal e As EventArgs)
lb1.DataSource = CultureInfo.GetCultures(CultureTypes.AllCultures)
lb1.DataTextField = "Names"
lb1.DataBind()
End Sub

You receive an instruction from management to make sure that the user’s selection in the lb1 ListBox control is retained during postback. You thus need to determine the appropriate code that should be added. What should you do?

  1. You should consider adding AddHandler lb1.SelectedIndexChanged, AddressOf BindData to the constructor of the page.
  2. You should consider adding AddHandler Me.Init, AddressOf BindData to the constructor of the page.
  3. You should consider adding AddHandler Me.PreRender, AddressOf BindData to the constructor of the page.
  4. You should consider adding AddHandler lb1.PreRender, AddressOf BindData to the constructor of the page.

Question: You work as an application developer at Company.com. The previous developer created a Microsoft ASP.NET application that uses Microsoft .NET Framework 3.5. You check and discover that the application has a DataSourceControl named _DS1. This DataSourceControl is bound to a database table hosted on the local computer. The primary key of the table is the SKU column. The code below is written in the FormView control. (The line numbers is included for reference purposes)
01 <tr>
02 <td align=”right”>
03 <strong>Products:</strong>
04 </td>
05 <td>
06 <asp:DropDownList ID=”_dl1″ DataSourceID=”_DS1″ DataTextField=”SKU”
07 DataValueField=”ProdID” Runat=”server” />
08 </td>
09 </tr>
You have to make sure that when the ProdID field is edited, the changes are updated to the database. What should you identify?

  1. Your best option would be to insert the following code between lines 06 and 07:
    SelectedValue='<%# Bind(“SKU”) %>’
  2. Your best option would be to insert the following code between lines 06 and 07:
    SelectedValue='<%# Bind(“ProdID”) %>’
  3. Your best option would be to insert the following code between lines 06 and 07:
    SelectedValue='<%# Eval(“ProdID”) %>’
  4. Your best option would be to insert the following code between lines 06 and 07:
    SelectedValue='<%# Eval(“SKU”) %>’

1 [Contract]
2 public interface IBlogService
3 {
4 [OpContract]
5 [WebGet(ResponseFormat=WebMessageFormat.Xml)]
6 Rss20FeedFormatter GetPost();

The Web form contains an XmlDocument variable named Testxml. You have to make sure that the result of the GetPost operation is stored in Testxml. What should you do?

  1. This can be accomplished by using the subsequent code segment:
    Uri _uri = new Uri(@”http://www.Company.com/BlogService”);
    ChannelFactory<IBlogService> _fact = new ChannelFactory<IBlogService>(_uri);
    IBlogService _srv = _fact.CreateChannel();
    Rss20FeedFormatter _feed = _srv.GetPost();
    Testxml.LoadXml(_feed.ToString());
  2. This can be accomplished by using the subsequent code segment:
    string _url = @”http://www.Company.com/BlogService”;
    XmlReader _reader = XmlReader.Create(_url);
    Testxml.Load(_reader);
  3. This can be accomplished by using the subsequent code segment:

    ChannelFactory<IBlogService> _fact = new
    ChannelFactory<IBlogService>(_uri);
    IBlogService _srv = _fact.CreateChannel();
    Rss20FeedFormatter _feed = _srv.GetPost();
    Testxml.LoadXml(_feed.Feed.ToString());
  4. This can be accomplished by using the subsequent code segment:
    string _url = @”http://www.Company.com/BlogService/GetPost”;
    XmlReader _reader = XmlReader.Create(_url);
    Testxml.Load(_reader);
