Microsoft TS: Windows Applications Development with Microsoft .NET Framework 4 Sample Questions:

1. You use Microsoft .NET Framework 4 to create a Windows Presentation Framework (WPF) application.
You plan to create a custom control that contains four text input fields. Each of the text input fields within the control will contain a label.
You need to ensure that the text input fields within the control can be validated by using a regular expression Validator.
Which class should you inherit from?

A) UIElement
B) TextElement
C) TextBox
D) UserControl

2. You are developing a Windows Presentation Foundation (WPF) application. You add a TextBox control to the design surface and bind it to an underlying window resource named dsGiftCertificate. The control uses the binding XAML as follows.
<Binding Source="{StaticResource dsGiftCertificate}"
UpdateSourceTrigger = "LostFocus" Path="Coupon" />
You need to provide a custom error message in the tooltip of the TextBox when the user leaves the textbox.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Update the binding source as follows.
<Binding Source="{StaticResource dsGiftCertificate}" UpdateSourceTrigger="Explicit"
Path="Coupon"ValidatesOnDataErrors="True" />
B) Implement the IDataErrorlnfo interface. Use the indexer for the custom validation and
error message.
C) Update the binding source as follows.
<Binding Source="{StaticResource dsGiftCertificate}" UpdateSourceTrigger="LostFocus"
Path="Coupon"ValidatesOnDataErrors="True" />
D) Implement the INotifyPropertyChanged interface. Use the indexer for the custom
validation and error message.

3. You are developing a Windows Presentation Foundation (WPF) application. The application contains a converter named DateOutputConverter that formats dates. The window is defined as follows. (Line numbers are included for reference only.)

The window must display the OrderDate value found in shippedOrder. The text box must display the OrderDate formatted by the DateOutputConverter.
You need to ensure that the OrderDate is displayed and formatted correctly.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) insert the following code at line 10.
<textBox Text="{Binding OrderDate}"/>
B) Insert the following code at line 10.
<textBox Text="{Binding OrderDate,
Converter={StaticResource internationalDateConverter}}"
DataContext.="{StaticResource ResourceKey=shippedOrder}"/>
C) Insert the following code at line 07.
<m:DateOutputConverter x:Key="internationalDateConverter"/>
D) Insert the following code at line 07.
<m:DataOutputConverter x:Key"DataOutputConverter"/>

4. You are developing a Windows Presentation Foundation (WPF) application.
You are implementing a test strategy for the application.
You need to ensure that the test class can repeat user input.
From which base class should the test class inherit?

A) AutomationElementIdentifier
B) Keyboard
C) UICues
D) AutomationPeer

5. DRAG DROP
You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
The application contains a window named Window1. Window1 contains several controls of the Label, TextBox, and Button types. You create the following style in a Window.Resources element:

You need to define a style named Style2 that meets the following requirements:
Has a blue background
Uses the same settings as Style1
Can only be applied to the TextBox controls
How should you complete the style? (To answer, drag the appropriate elements to the correct locations. Each element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)
