You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will contain an enumeration named OrderState. The OrderState enumeration will contain the following four values:

Processing
Cancelled
Confirmed
Closed

The client application must be able to set the state of an Order entity to only the following two values:

Cancelled
Closed

You need to create the data contract for OrderState. Which code segment should you use?

You create a Microsoft ASP.NET application by using the Microsoft .NET Framework
version 3.5.You create a Web form by using ASP.NET AJAX.You write the following
client-script code fragment to handle the exceptions thrown from asynchronous postbacks.
(Line numbers are included for reference only.)
01 <script type=”text/javascript”>
02 function pageLoad()
03 {
04 var pageMgr =
05 Sys.WebForms.PageRequestManager.getInstance();
06
07 }
08
09 function errorHandler(sender, args)
10 {
11
12 }
13 </script>
You need to ensure that the application performs the following tasks:
Use a common client-script function named errorHandler.

Update a Label control that has an ID named lblError with the error message.
Prevent the browser from displaying any message box or Javascript error.
What should you do?

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the following service contract. (Line numbers are included for reference only.)

01 [ServiceContract]
02 public interface IMyService
03 {
04 [OperationContract]
06 List<string> GetData(int index);
07 }

You need to ensure that the GetData operation can be accessed by using the URI in the following manner:

GetData/1 for the index value 1
GetData/2 for the index value 2
..
GetData/n for the index value n

Which code segment should you insert at line 05?

You create a Microsoft ASP.NET application by using the Microsoft .NET Framework
version 3.5.You write the following code segment to create a client-script function. (Line
numbers are included for reference only.)
01 function updateLabelControl(labelId, newText) {
02 var label = $find(labelId);
03 label.innerHTML = newText;
04 }
The client script function uses ASP.NET AJAX and updates the text of any Label control in
the Web form.When you test the client script function, you discover that the Label controls
are not updated. You receive the following JavaScript error message in the browser: “‘null’ is
null or not an object.” You need to resolve the error.What should you do?

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You have successfully defined a service contract named IManageOrders. You write the following code segment.

public class OrderImpl : IManageOrders {
public void MarkOrderClosed(int orderId){
try {
…
}
catch (SqlException exc){
throw new FaultException<DataFault>(new DataFault()); }}}
[DataContract]

public class DataFault {
}

You need to create a fault contract for the MarkOrderClosed method on the IManageOrders service contract. Which code segment should you add?

You create a Microsoft ASP.NETWeb application by using the Microsoft .NET Framework
version 3.5.You add the following code fragment to an AJAX-enabled Web form. (Line
numbers are included for reference only.)
01 <asp:ScriptManager ID=”scrMgr” runat=”server” />
02 <asp:UpdatePanel ID=”updPanel” runat=”server”
03 UpdateMode=”Conditional”>
04 <ContentTemplate>
05 <asp:Label ID=”lblTime” runat=”server” />
06 <asp:UpdatePanel ID=”updInnerPanel”
07 runat=”server” UpdateMode=”Conditional”>
08 <ContentTemplate>
09 <asp:Timer ID=”tmrTimer” runat=”server”
10 Interval=”1000″
11 OnTick=”tmrTimer_Tick” />
12 </ContentTemplate>
13
14 </asp:UpdatePanel>
15 </ContentTemplate>
16
17 </asp:UpdatePanel>
The tmrTimer_Tick event handler sets the Text property of the lblTime Label control to the
current time of the server.You need to configure the appropriate UpdatePanel control to
ensure that the lblTime Label Control is properly updated by the tmrTimer Timer control.
What should you do?

You create a Microsoft ASP.NET application by using the Microsoft .NET Framework
version 3.5.You write the following code fragment. (Line numbers are included for reference
only.)
01 <asp:UpdatePanel ID=”upnData” runat=”server”
02 ChildrenAsTriggers=”false” UpdateMode=”Conditional”>
03 <Triggers>
04
05 </Triggers>
06 <ContentTemplate>
07 <!– more content here –>
08 <asp:LinkButton ID=”lbkLoad” runat=”server” Text=”Load”
09 onclick=”lbkLoad_Click” />
10 <asp:Button ID=”btnSubmit” runat=”server” Text=”Submit”
11 Width=”150px” onclick=”btnSubmit_Click” />
12 </ContentTemplate>
13 </asp:UpdatePanel>
14 <asp:Button ID=”btnUpdate” runat=”server” Text=”Update”
15 Width=”150px” onclick=”btnUpdate_Click” />
You need to ensure that the requirements shown in the following table are met. What should you do?
