  You are developing a Windows Presentation Foundation (WPF) application. Users can enter formatted percentages into text boxes. The markup is as follows.

  Percentage is a decimal property.

  You need to store the percentages as their decimal values, not their display values.

  Which code segment should you use?

  A. public object Convert (object value, Type targetType, object parameter, CultureInfo culture) { return ((decimal)value).ToString("P"); }
  B. public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { return (decimal.Parse(value.ToString()) / 100); }
  C. public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { return (decimal.Parse(parameter.ToString()) / 100); }
  D. public object Convert(object value. Type targetType, object parameter, CultureInfo culture) { return ((decimal)parameter).ToString(nPn); }
  B. public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { return (decimal.Parse(value.ToString()) / 100); }

• Question 222:

  You are developing a Windows Presentation Foundation (WPF) application.

  An event triggers a workflow such that a parent control executes the event handlers before the child controls.

  You need to ensure that if a parent control's event handler encounters an error, the subsequent handlers are not called.

  What should you do?

  A. Use handlers for a tunneling routed event and mark the event as handled in the case of a problem.
  B. Use handlers for a tunneling routed event and mark the event as handled in the Finally portion of a Try-Catch-Finally code block.
  C. Use handlers for a bubbling routed event and mark the event as handled in the case of a problem.
  D. Use handlers for a bubbling routed event and set the Handled property of the RoutedEventArgs object to True in the Catch portion of a Try-Catch-Finally code block.
  D. Use handlers for a bubbling routed event and set the Handled property of the RoutedEventArgs object to True in the Catch portion of a Try-Catch-Finally code block.

• Question 223:

  You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application contains a formnamed frmMain that contains a button named btnSave.

• Question 224:

  You use Microsoft .NET Framework to create a Windows Presentation Foundation (WPF) application.

  You create a window that contains a Button control and a MenuItem control. Both controls are labeled "Add sugar." The Command properties of the Button and MenuItem controls are set to the same RoutedCommand named

  AddSugarCommand.

  You write the following code segment.

  Private Sub CanAddSugar(sender As Object, e As CanExecuteRoutedEventArgs) ...

  End Sub

  You need to ensure that when the CanAddSugar method sets e.CanExecute to false, the MenuItem and Button controls are disabled.

  What should you do?

  A. Create an event handler for the CanExecuteChanged event of the AddSugarCommand command. Call the CanAddSugar method from within the event handler.
  B. Inherit the AddSugarCommand from the RoutedUICommand class instead of the RoutedCommand class. Call the CanAddSugar method from within the constructor of the AddSugarCommand command.
  C. Add a CommandBinding object to the CommandBinding property of the MenuItem control. Set the CanExecute property of the CommandBinding object to the CanAddSugar method.
  D. Add a CommandBinding object to the CommandBindings property of the window. Set the Command property of CommandBinding to the AddSugarCommand command. Set the CanExecute property of the CommandBinding object to the CanAddSugar method.
  D. Add a CommandBinding object to the CommandBindings property of the window. Set the Command property of CommandBinding to the AddSugarCommand command. Set the CanExecute property of the CommandBinding object to the CanAddSugar method.

  Where should you store the application data?

  A. In isolated storage
  B. On the database server
  C. In the ClickOnce data directory
  D. in the App.config file of the application
  A. In isolated storage

• Question 227:

  You are developing a Windows Presentation Foundation (WPF) application that will be deployed by using ClickOnce.

  You have a file named CONTOSOEULA.docx that is part of the project.

  CONTOSOEULA.docx must be deployed during the setup of the application.

  You discover that CONTOSOEULA.docx does not appear in the Application Files settings. You need to ensure that CONTOSOEULA.docx is included in the Application Files.
