You are developing a Windows Presentation Foundation (WPF) application. You are writing data templates for a calendar.
You must use the Weekend template for weekends and the Weekday template for weekdays. The Window markup is as follows. (Line numbers are included for reference only.)

You need to ensure that the Weekend and Weekday templates are applied correctly to the ListBox control.
Which markup segment should you insert at line 11?

• A. <ListBox ItemTemplate="{Binding WeekendSelector} "/>
• B. <ListBox ItemTemplate="{StaticResource WeekendSelector} "/>
• C. <ListBox ItemTemplateSelector="{Binding WeekendSelector}"/>
• D. <ListBox ItemTemplateSelector="{StaticResource WeekendSelector}"/>

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application uses the background worker process (BWP).
When the user clicks a button, the background worker executes a method named DoCalculations asynchronously.
You need to implement a progress bar on the user interface (UI) that Informs the user of the progress of DoCalculations.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Call the ReportProgress method of the background worker in the DoWork event handler of the background worker.
• B. Modify the Value property of the progress bar in DoCalculations.
• C. Call the ReportProgress method of the background worker in DoCalculations.
• D. Modify the Value property of the progress bar in the ProgressChanged event handler of the background worker.
• E. Modify the Value property of the progress bar in the RunWorkerCompleted event handler of the background worker.

You are developing a Windows Presentation Foundation (WPF) application. You have a class named Orders, which contains OrderId and ShipOn properties. You place a control in the MainWindow.xaml file, as follows. (Line numbers are included for reference only.)

When you run the application, the ComboBox control displays the class name for every row.
You need to ensure that the ComboBox control displays the OrderId and ShipOn values in columns.
Which markup segment should you add at line 03?

• A. <ItemsControl.Itemlempiate>
  <DataTempIate>
  <Grid>
  <Grid.ColumnDefinitions>
  <ColumnDefinition />
  <ColumnDefinicion />
  </Grid.ColumnDefinitions>
  <TextBlock Grid.Coxumn"0" Text="{Binding OrderId}"/>
  <TextBlock Grid.Coxumn"1" Text="{Binding ShipOn}"/></Grid>
  </DataTemplate>
  </ItemsControl.ItemTemplate>
• B. <ItemsControl.ItemsPanel>
  <ItemsPanelTemplate>
  <Grid>
  <Grid.ColumnDefinitions>
  <ColumnDefinition />
  <CoIumndefinltion />
  </Grid.ColumnDefinitions>
  <TextBlock Grid.Column-"0" Text="{Binding ShipOn}"/>
  <TextBlock Grid.Column"0" Text="{Binding OrderId}"/></Grid>
  </ItemsPanelTemplate>
  </ItemsControl.ItemsPanel>
• C. <ItemsControl.ItemsPanel>
  <ItemsPanelTemplate>
  <Grid>
  <TextBlock Text ="{Binding OrderId}/ >
  <TextBlock Text ="{Binding ShipOn}/ >
  </Grid>
  </ItemsPanelTemplate>
  </ItemsControl.ItemPanel>
• D. <ItemsControl.ItemTempIate>
  <DataTemplate>
  <Grid>
  <TextBlock Text="{Binding OrderId}"/>
  <TextBlock Text="{Binding ShipOn}"/>
  </Grid>
  </DataTemplate>
  </ItemsControl.ItemTemplate

You are developing a Windows Presentation Foundation (WPF) application. A TextBlock control has DataContext bound to a static resource named Book. The ToolTip attribute of TextBlock displays the full book titles.
You create a converter named TrimTitleConverter to shorten the book titles to three words in the Text attribute of the TextBox. You add the converter to the Resources section of the MainWindow.xaml file as follows. (Line numbers are included for reference only.)

You need to ensure that the shortened book titles appear only in the Text attribute of TextBlock.
Which markup segment should you use to replace lines 06 through 09?

• A. <TextBlock
  ToolTip="{Binding Title,
  Converter-{StatlcResource ResourceKey=TrimConverter)}"
  Text-"(Binding RelativeSource-
  {RelativeSource TeaplatedParent}, Path-ToolTip}" DataContext = "{StaticResource
  ResourceKey=Book} "/>
• B. <TextB1ock
  ToolTip="{Binding Title)" Text="{Binding RelativeSource=
  {RelativeSource TemplatedParent}, Path=ToolTip,
  Converter{StaticResource ResourceKey=TrimConverter}}" DataContext="{StaticResource
  ResourceKey=Book)"/>
• C. <TextBlock
  ToolTip="{Binding Title,
  Converter={StaticResource ResourceKeyTrimConverter}}"
  Text=Binding RelativeSource-
  {ReiativeSaurce Self), Path-ToolTip}" DataContext-"{StaticResource ResourceKey-Book) "/>
• D. <TextBlock
  ToolTip-"{Binding Title}"
  Text={Binding RelativeSource=
  {RelativeSource Self}, Path=ToolTip,
  Converter={StaticResource ResourceKey=TrimConverter}}" DataContext="{StaticResource
  ResourceKey=Book"/>

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
The application contains a window as shown in the following exhibit.

You need to define a DockPanel control that fits the window.
Which code fragment should you use?

• A. <DockPanel>
  <Button Content="Left"/>
  <Button Content="Top" DockPanel.Dock="Top"/><Button Content="Bottom"
  DockPanel.Dock="Bottom"/><Button Content="Center"/></DockPanel>
• B. <DockPanel>
  <Button Content="Top" DockPanel.Dock="Top"/><Button Content-"Left"/><Button
  Content="Center"/>
  <Button Content="Bottom" DockPanel.Dock="Bottom"/></DockPanel>
• C. <DockPanel>
  <Button Content-"Left"/>
  <Button Content="Top" DockPanel.Dock="Top"'><Button Content="Center"/>
  <Button Content="Bottom" DockPanel.Dock="Bottom"/></DockPanel>
• D. <DockPanel>
  <Button Content="Top" DockPanel.Dock="Top"/><Button Content="Bottom"
  DockPanel.Dock"Bottom'7><Button Content="Left"/><Button
  Content="Center"/></DockPanel>
