You are developing a Windows Presentation Foundation (WPF) application.
The application's main window lists a series of controls horizontally until a control reaches the edge of the window. At that point, the series of controls continues on a new line. You need to ensure that this layout persists when the user changes the size of the window. What should you do?

• A. Place each control in a WrapPanel control and set its Orientation property to Horizontal.
• B. Place each control in a StackPanel control and set its Orientation property to Horizontal.
• C. Place the controls in a grid and define the rows and columns using star sizing.
• D. Place each control in a DockPanel control and set its Dock property to Left.

You are developing a Windows Presentation Foundation (WPF) application.
A user control responds to a click event. The click event handler sets the Handled property to true.
You need to ensure that a parent control responds to the event after the user control's handler executes.
What should you do?

• A. Add a bubbling routed event handler to the parent control.
• B. Programmatically add an event handler to the parent control and set the HandledEventsToo property to true.
• C. Add a tunneling routed event handler to the parent control.
• D. Programmatically add an event handler to the parent control and set the HandledEventsToo property to false.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a
Windows Presentation Foundation (WPF) application.
You write the following code fragment.
< TextBox Text="{Binding Path=StringMember} " / >
You need to ensure that the StringMember property of the data-bound object is updated
immediately when the user types in the TextBox control.
Which binding expression should you use?

• A. {Binding Path=StringMember, Mode=Two way}
• B. {Binding Path=StringMember, NotifyOnSourceUpdated=True}
• C. {Binding Path=StringMember, NotifyOnTargetUpdated=True}
• D. {Binding Path=StringMember, UpdateSourceTrigger=PropertyChanged}

You are developing a Windows Presentation Foundation (WPF) application.
Users can enter formatted percentages into text boxes.
The markup is as follows.
<TextBox Text="{Binding Path=Percentage,
Converters StaticResource PercentValueConverter}}" />
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 Function ConvertBack(
  ByVal value As Object, ByVal targetType As Type,
  ByVal parameter As Cliiert, ByVal culture As cultureInfo)
  As Object
  Return (Decimal.Parse (parameter.ToString ()) / 100)
  End Function
• B. Public Function Convert (
  ByVal value As Object, ByVal targetType As Type,
  ByVal parameter As Object, ByVal culture As CultureInfo)
  As Object
  Return CDec(value).ToString("P")
  End Function
• C. Public Function ConvertBack{
  ByVal value As Object, ByVal targetType As Type,
  ByVai parameter As Object, ByVal culture As CultureInfo)
  As Object
  Return (Decimal.Parse(value.ToString()) / 100)
  End Function
• D. Public Function Convert (
  ByVal value As Object, ByVal targetType As Type,
  ByVal parameter As Object, ByVal culture As CultureInfo)
  As Object
  Return CDec (parameter) .ToStrmg ("P")
  End Function

You create a Microsoft Windows Installer file for a Windows Presentation Foundation (WPF) application that requires Microsoft .NET Framework 4.
You need to ensure that the installation starts only if .NET Framework 4 is already installed on the computer.
What should you do?

• A. Set the MinVersion property to .NET Framework 4.
• B. Set the Version property of the Launch Condition to .NET Framework 4.
• C. Set the Version property of Windows Installer to .NET Framework 4.
• D. Use a custom action.
