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

• Question 103:

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

  The movement of a control within the application is animated.

  You need to ensure that the animated control is continually animated in one direction.

• Question 104:

  You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.

  You add a TreeView control to show the hierarchical structure of orders and order details. Each order contains an ObservableCollection named OrderDetails.

  You write the following code fragment. (Line numbers are included for reference only.)

  

  You need to ensure that the TreeView control meets the following requirements:

  

  Each order is shown as a TreeView node.

  

  The order nodes have order detail nodes as children.

  Which code fragment should you insert at line 07?

  B

• Question 105:

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

  Two styles, Blue and Green, are used for Border objects. The two styles have the same values for the CornerRadius and BrushThickness properties and different values for the Background property.

  You need to define the CornerRadius and BrushThickness settings in either the Blue or the Green style, but not both.

  What should you do?

  A. Separate Blue and Green into two files. Put the base settings in Blue and use MergedDictionaries. Ensure that the Green file is second in the list.
  B. Put Blue and Green into the same file. Put the base settings in Blue and mark Green as BasedOn Blue.
  C. Put Blue and Green into the same file. Put the base settings in Blue and mark Blue as BasedOn Green.
  D. Separate Blue and Green into two files. Put the base settings in Blue and use MergedDictionaries. Ensure that the Blue file is second in the list.
  B. Put Blue and Green into the same file. Put the base settings in Blue and mark Green as BasedOn Blue.

• Question 106:

  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=TwoWay }
  B. { Binding Path=StringMember, NotifyOnSourceUpdated=True }
  C. { Binding Path-StringMember, NotifyOnTargetUpdated=True }
  D. { Binding Path=StringMember, UpdateSourceTrigger=PropertyChanged }
  D. { Binding Path=StringMember, UpdateSourceTrigger=PropertyChanged }

• Question 107:

  You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.

  You add a property named ServiceContext to a control.

  You need the value of ServiceContext to flow to the child controls exactly like the value of the DataContext property of the FrameworkElement class.

  What should you do?

  A. Inherit the control class from the DependencyObject class.
  B. Register a dependency property. In the options settings of the property metadata, specify the Inherits option.
  C. Declare a new property. In the get and set methods of the new property, create an instance of the TraversalRequest class.
  D. Declare a new property. In the get method of the new property call VisualTreeHelper.GetParent. In the set method of the new property, call VisualTreeHelper.GetChild.
  C. Declare a new property. In the get and set methods of the new property, create an instance of the TraversalRequest class.

• Question 108:

  You are developing a Windows Presentation Foundation (WPF) application that displays opportunities from List (Of T) named Leads, where T is a class named Lead. The Lead class contains the properties Title and Revenue.

  You add a DataGrid control named dgQualifiedLeads to the MainWindow.xaml file. You set the ItemSource property of dgQualifiedLeads to Leads as follows. (Line numbers are included for reference only.)

  

  You need to ensure that CollectionViewSource is used to filter the list to display only Lead objects with revenue of more than $1,000.

  What should you do?

  A. Insert the following code at line 22. Leads.Filter = New Predicate (Of Object)(AddressOf FilterOut) Add the following code segment to the code-behind of the MainWindow.xaml file. Public Function FilterOut(ByVal item As Object) As Boolean Dim lead As Lead = TryCast(item, Lead) Return IIf(lead.Revenue < 1000D, True, False) End Function
  B. Insert the following code at line 22. Leads.Filter = New Predicate (Of Object)(AddressOf FilterOut) Add the following code segment to the code-behind of the MainWindow.xaml file. Public Function FilterOut(ByVal item As Object) As Boolean Dim lead As Lead TryCast(item, Lead) Return IIf(lead.Revenue > 1000D, False, True) End Function
  C. Insert the following code at line 22. Leads.Filter = New Predicate(Of Object)( Function(s) DirectCast(s. Lead).Revenue > 1000D)
  D. Insert the following code at line 22. Leads.SortDescriptions.Add(New SortDescription( "Revenue", ListSortDirection.Ascending))
  C. Insert the following code at line 22. Leads.Filter = New Predicate(Of Object)( Function(s) DirectCast(s. Lead).Revenue > 1000D)

• Question 109:

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

  A UserControl named usercontroll contains the following controls.

  You need to ensure that the content of the label displays "New Content!!!" programmatically from the code-behind of the application window that contains the UserControl.

  B. userControl1.Content = "New Content!!!";
  C. var label = userControl1.FindResource("label1") as Label; label.Content = "New Content!!!";
  D. DependencyProperty dp =DependencyPropercy.Register("label1",typeof(Label), typeof(Window), new PropertyMetadata("New Content!!!")); userControl1.CoerceValue(dp);
  A. var label = userControll.FindName ("label1") as Label; label.Content = "New Content!!!";

  A. Add an Ellipse element to the control. Use Ellipse.Stroke and ImageBrush with the image as ImageSource.
  B. Add an Image.Clip element to the control. Use LineGeometry within Image.Clip.
  C. Add an Ellipse element to the control. Use Ellipse.Fill and ImageBrush with the image as ImageSource.
  D. Add an Image.Clip element to the control. Use EllipseGeometry within Image.Clip.
