You are developing a Windows Presentation Foundation (WPF) application. You have the following style defined in the app.xaml file.
<Style x:Key="btnItalic" x:Name="styIeItalic"
TargetType="{ x:Type Button}">
Setter Property="FontStyle" Value="Itallc"/></Style>
You need to apply this style to a button named button1 in the application at run time.
Which code segment should you use?

• A. button1.Style = TryCast(Me.FindName("styleItalic"),Style)
• B. button1.Style = TryCast(Me.FindResource("btnItalic"), Style)
• C. button1.Style = TryCast(Me.FindResource("styleItalic"), Style)
• D. button1.Style = TryCast(Me.FindName("btnItalic"), Style)

You develop a Windows Presentation Foundation (WPF) application. This application is used to output data trends to customer service representatives.
A data trend analysis is performed in a function named UpdateTrendData. The trend analysis is a long-running process.
The application contains the following code segment.
Class MainWindow: Window {
private void UpdateData(object arg)
{
double data = UpdateTrendData();
... } }
UpdateData is currently invoked on the UI thread when the form is first displayed. You need to process the data in a manner that does not cause the UI to freeze. What should you do?

• A. Use this.Dispatcher.BeginInvoke to invoke UpdateData passing in the priority of Background.
• B. Use ThreadPool.SetMaxThreads(2, 2) and invoke UpdateData.
• C. Use this.Dispatcher.Beginlnvoke to invoke UpdateData passing in the priority of Normal.
• D. Use ThreadPool.QueueUserWorkItem to invoke UpdateData.

You are develping a Windows Presentation Foundation (WPF) application.
You plan to deploy the WPF application by using ClickOnce. The application will be associated to files that have an extension of .abc.
You need to ensure that when a user opens the application by double-clicking an .abc file, a TextBlock named txtBlockl displays the path of the file.
Which code should you use?

• A. txttBlock1.Text = App.Current.Properties["FilePath"].ToString();
• B. txtBlock1.Text = AppDomain. CurrentDomain.Setup Information. ActivationArguments. ActivationData \0\ .ToString ();
• C. txtBlock1.Text = DataContext .ToString ();
• D. txttBlock1.Text = App.Current.Properties["ActivationData"].ToString();

You are developing a Windows Presentation Foundation (WPF) application. The application contains the following markup.

You need to ensure that the Filter combo box is hidden when the expander is collapsed.
What should you do?

• A. Add the following DataTrtgger element to the Expander control.
  <DataTrigger Binding="{Binding ElementName=Filter, Path=Visibility}= Value="Collapsed">
  <Setter Property="Expander.IsExpanded"
  Value="False" />
  </DataTrigger>
• B. Add the following DataTrigger element to the Expander control.
  <DataTrigger Binding="{Binding ElementName=Filter, Path=isExpanded} " Value="False">
  <Setter Property="UIElementVisibility"
  Value="Collapsed" />
  </DataTrigger>
• C. Add the following DataTrigger element to the ComboBox control.
  DataTrigger Binding=" {Binding ElementName=Products, Path=isExpanded>
  "Value="False">
  <Setter Property="UIElement.Visibility"
  Value="Collapsed"/>
  </DataTrigger>
• D. Add the following DataTrigger element to the ComboBox control.
  <DataTrigger Binding= "{Binding ElementName=Products, Path=Visibility}"
  Value="Collapsed">
  <Setter Property="Expander.IsExpanded"
  Value="False"/>
  </DataTrigger>

You are developing a Windows Presentation Foundation (WPF) application for managing student information. You place a Button control named btnSort and a DataGrid control named dgStudents on the design surface of the MainWindow.xaml file. You create a Student class with two properties: FirstName and LastName. You create the following code segment in the constructor of the main window.

The DataGrid control displays the list of students unsorted.
You need to ensure that the list of students is sorted by last name.
Which code segment should you add to the click event handler of the Button control?

• A. Students.Reversed dgStudents.ItemsSource = Students
• B. Dim sortedStudents As IEnumerable(Of Student) Students.orderBy (Function (s) s.LastName) dgStudents.ItemsSource = sortedStudents
• C. Dim sortedStudents As IEnnumerable(Of Student) = Students.OrderBy(Function(s) s.LastName).ToList() dgstudents.ltemssource = sortedStudents
• D. Students.Sort() dgStudents.ItemsSource = Students
