Q12
DRAG DROP
You are developing a Universal Windows Platform (UWP) app. The app will display a text box named TextBox1 and a button named Button2. If a user types in the text box, you need to ensure that the box is resized dynamically based on the size of the text. The buttons must always remain to the right of the text box and must always remain aligned.
How should you complete the code? To answer, drag the appropriate code elements to the correct targets. 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.
Answer:
Explanation:
The new RelativePanel implements a style of layout that is defined by the relationships between its child elements. It’s intended for use in creating app layouts that can adapt to changes in screen resolution.
Example:
<RelativePanel>
<TextBox x:Name=”textBox1″ Text=”textbox” Margin=”5″/> <Button x:Name=”blueButton” Margin=”5″ Background=”LightBlue” Content=”ButtonRight” RelativePanel.RightOf=”textBox1″/>
<Button x:Name=”orangeButton” Margin=”5″ Background=”Orange” Content=”ButtonBelow” RelativePanel.RightOf=”textBox1″ RelativePanel.Below=”blueButton”/> </RelativePanel>

In MainPage.xaml, you have the following markup.
You plan to implement localization for the following cultures:
de-DE
fr-CA
en-US
You create a folder within the project named Strings that contains a subfolder for each culture. Each subfolder contains a resource file named Greetings.resw. You need to ensure that TextBlock appears by using the appropriate localization. Which two modifications should you make to MainPage.xaml? Each correct answer presents part of the solution.
A. Replace x:Name with x:Phase.
B. Change “Greeting” to “Resources/Greeting”.
C. Change “Greeting” to “Greetings/Greeting”.
D. Replace x:Name with x:FieldModifier.
E. Replace x:Name with x:Uid.
F. Change “Greeting” to “Greetings.resw/Greeting”.
