You are developing a Windows Forms application that contains a DataGridView control. The DataGridView is composed of several fields that capture the customer's name, address, and phone number.
You have been asked to provide data validation in a DataGridView to prevent users from leaving the name field if the name field is empty.
You need to ensure that users cannot tab out of the name field without entering data.
What should you do?

• A. Validate the name field in the CellValidating event. Set e.Cancel - true if the name field is empty.
• B. Validate the name field in the CancelRowEdit event. Set the focus on the name field if the name field is empty.
• C. Validate the name field in the CellErrorTextChanged event. Get e.RowIndex if the name field is empty.
• D. Validate the name field in the CellEnter event. Set the focus on the name field if the name field is empty.

You are developing a Windows Presentation Foundation (WPF) application. The window has the following markup. (Line numbers are included for reference only.)

You need to ensure that all ListBox controls have a border that matches the background color of the ListBox template.
Which markup segment should you insert at line 15?

• A. <Border Background="<Binding ListBox.Background)">
  <ItemsPresenter />
  </Border>
• B. <Border Background="TemplateBinding ListBox.Background)">
  <ContentPresenter />

You are developing a Windows Presentation Foundation (WPF) application to play audio files. You add a MediaElement control named mediaElementl and a Button control named btnPlayAudio to the design surface. The MediaElement control Source attribute is set to an audio file. The LoadedBehavior attribute is set to Manual.
You add the following code to the main window.
void playCommand_Executed(object sender, RoutedEventArgs e) {
mediaElementl.Play();
} You set the command of the button to MediaCommands.Play.
You need to ensure that the application will play the audio file when the button is pressed.
What should you add to the constructor of the main window?

• A. RoutedUICommand playCommand = new RoutedUICommand(); playCommand.CanExecuteChanged += new EventHandler(playCommand_Executed); this.CommandBindings.Add(new CommandBinding(playCommand));
• B. CommandBinding playCommand = new CommandBinding(MediaCommands.Play); playCommand.Executed += new ExecutedRoutedEventHandler(playCommand_Executed); this.CommandBindings.Add(playCommand);
• C. CommandBinding playCommand = new CommandBinding(MediaCommands.Play); playCommand.CanExecute += new CanExecuteRoutedEventHandler(playCommand_Executed); this.CommandBindings.Add(playCommand);
• D. RoutedCommand playCommand = new RoutedCommand(); playCommand.CanExecuteChanged += new EventHandler(playCommand_Executed); this.CommandBindings.Add(new CommandBinding(playCommand));
