CodeFile="OrderDetails.aspx.vb" Inherits="OrderDetails" %>


<customErrors mode="Off" defaultRedirect="OrderError.htm">

</customErrors>

B. Set the Page attribute for the OrderDetails.aspx Web page in the following manner.



CodeFile="OrderDetails.aspx.vb" Inherits="OrderDetails" Debug="true" %>


<customErrors mode="On" defaultRedirect="OrderError.htm">

C. Set the Page attribute for the OrderDetails.aspx Web page in the following manner.


CodeFile="OrderDetails.aspx.vb" Inherits="OrderDetails"

ErrorPage="~/OrderError.htm" Debug="false" %>


<customErrors mode="On">

</customErrors>

D. Set the Page attribute for the OrderDetails.aspx Web page in the following manner.


CodeFile="OrderDetails.aspx.vb" Inherits="OrderDetails" Debug="true"

ErrorPage="~/OrderError.htm" %>


<customErrors mode="Off">

</customErrors>

Answer: C



<asp:ScriptManager ID="ScriptManager1" runat="server" />

<asp:UpdatePanel ID="updateLabels" runat="server"

UpdateMode="Conditional">

<ContentTemplate>

<asp:Label ID="Label1" runat="server" />


<asp:Button ID="btnSubmit" runat="server" Text="Submit"

onclick="btnSubmit_Click" />


</ContentTemplate>

</asp:UpdatePanel>

<asp:Label id="Label3" runat="server" />

You need to ensure that when you click the btnSubmit Button control, each Label control value is

asynchronously updatable.


A. protected void btnSubmit_Click(object sender, EventArgs e)

{

Label1.Text = "Label1 updated value";



}

B. protected void btnSubmit_Click(object sender, EventArgs e)

{



ScriptManager1.RegisterDataItem(Label3, "Label3 updated value");

}

C. protected void btnSubmit_Click(object sender, EventArgs e)

{




}

D. protected void btnSubmit_Click(object sender, EventArgs e)

{



ScriptManager1.RegisterAsyncPostBackControl(Label3);



}

Answer: B



<asp:ScriptManager ID="ScriptManager1" runat="server" />

<asp:UpdatePanel ID="updateLabels" runat="server"


<ContentTemplate>



<asp:Button ID="btnSubmit" runat="server" Text="Submit"

onclick="btnSubmit_Click" />

</ContentTemplate>

</asp:UpdatePanel>

<asp:Label id="Label3" runat="server" />

You need to ensure that when you click the btnSubmit Button control, each Label control value is

asynchronously updatable.


A. Protected Sub btnSubmit_Click(ByVal sender As Object, _


Label1.Text = "Label1 updated value"



End Sub

B. Protected Sub btnSubmit_Click(ByVal sender As Object, _





ScriptManager1.RegisterDataItem(Label3, _

"Label3 updated value")

End Sub

C. Protected Sub btnSubmit_Click(ByVal sender As Object, _







End Sub

D. Protected Sub btnSubmit_Click(ByVal sender As Object, _




ScriptManager1.RegisterAsyncPostBackControl(Label3)


End Sub

Answer: B


You create a Web form in the application by using the following code fragment. (Line numbers are



02 protected void Button_Handler(object sender, EventArgs e)

03 {

04 // some long-processing operation.

05 }


06 </script>

07 <div>

08 <asp:ScriptManager ID="defaultScriptManager"

09 runat="server" />

10

11 <asp:UpdatePanel ID="defaultPanel"

12 UpdateMode="Conditional" runat="server">

13 <ContentTemplate>

14 

15 <asp:Button ID="btnSubmit" runat="server"

16 Text="Submit" OnClick="Button_Handler" />

17 </ContentTemplate>

18 </asp:UpdatePanel>

19 </div>

You plan to create a client-side script code by using ASP.NET AJAX.

You need to ensure that while a request is being processed, any subsequent Click events on the

btnSubmit Button control are suppressed.

Which code fragment should you insert at line 10?

A. <script type="text/javascript" language="javascript">

var rm = Sys.WebForms.PageRequestManager.getInstance();

rm.add_beginRequest(checkPostback);

function checkPostback(sender, args) {

if (rm.get_isInAsyncPostBack() &&

args.get_postBackElement().id == 'btnSubmit') {

rm.abortPostBack();

alert('A previous request is still in progress.');

}

}

</script>

B. <script type="text/javascript" language="javascript">


rm.add_initializeRequest(checkPostback);




rm.abortPostBack();


}

}

</script>

C. <script type="text/javascript" language="javascript">






args.set_cancel(true);


}

}

</script>

D. <script type="text/javascript" language="javascript">




var request = args.get_request();




request.completed(new Sys.CancelEventArgs());


}

}

</script>

Answer: C


You write the following code segment to create a JavaScript file named CalculatorScript.js.

function divide(a, b) {

if (b == 0) {

var errorMsg = Messages.DivideByZero;

alert(errorMsg);

return null;


}

return a/b;

}

You embed the CalculatorScript.js file as a resource in a Class Library project. The namespace for this

project is Calculator.Resources. The JavaScript function retrieves messages from a resource file named

MessageResources.resx by using the JavaScript Messages object.

You add an AJAX Web form in the ASP.NET application. You reference the Class Library in the application.

You add an ASP.NET AJAX ScriptReference element to the AJAX Web form.

You need to ensure that the JavaScript function can access the error messages that are defined in the

resource file.

Which code segment should you add in the AssemblyInfo.cs file?

A. [assembly: ScriptResource

("CalculatorScript", "MessageResources", "Messages")]

B. [assembly: ScriptResource

("CalculatorScript.js", "MessageResources.resx", "Messages")]

C. [assembly: ScriptResource

("Calculator.Resources.CalculatorScript.js", "Calculator.Resources.MessageResources", "Messages")]

D. [assembly: ScriptResource

("Calculator.Resources.CalculatorScript", "Calculator.Resources.MessageResources.resx",

"Messages")]
