2. XAML was developed by

Microsoft

Amazon

Apple

W3 schools

XAML (eXtensible Application Markup Language) was developed by Microsoft. It is a markup language used to define user interfaces for applications in the .NET framework. XAML allows developers to separate the design and logic of an application, making it easier to create and maintain complex user interfaces. It is primarily used in Microsoft technologies such as Windows Presentation Foundation (WPF), Universal Windows Platform (UWP), and Silverlight.

6. Which of the following are used to attract the attention of the user to a change?

Animations

Transitions

Pictures

Diagrams

Animations are used to attract the attention of the user to a change. Unlike static elements like pictures and diagrams, animations involve movement and dynamic visual effects, which can effectively capture the user's attention and highlight any changes or updates on a webpage or application. Transitions, on the other hand, refer to the smooth movement between different states or screens and can also be used to draw attention to changes. However, in this case, only animations are mentioned as the correct answer.

7. A control that responds to user input is

Key

Button

ComboBox

CheckBox

A button is a control that responds to user input by performing a specific action when it is clicked. It is commonly used in user interfaces to initiate an action or trigger a function. Unlike a key, which is typically used for keyboard input, a button is a visual element that can be clicked with a mouse or tapped on a touch screen. A ComboBox and CheckBox are also user input controls, but they have different functionalities compared to a button.

There are two types of data binding in XAML. Data binding is a technique used to establish a connection between the UI elements and the data source, allowing the UI to automatically update when the data changes. The two types of data binding in XAML are "One-Way" and "Two-Way" data binding. One-Way data binding allows data to flow in one direction, from the data source to the UI element. Two-Way data binding allows data to flow in both directions, allowing changes made in the UI to be reflected back to the data source.

9. The following are types of Triggers except

Basic Triggers

Property Triggers

Event Triggers

Data Triggers

The given options list different types of triggers, namely Property Triggers, Event Triggers, and Data Triggers. The term "except" indicates that we need to identify the type of trigger that is not included in the given options. Since the option "Basic Triggers" is not mentioned in the list, it can be inferred that Basic Triggers are the type of trigger that is not included in the given options.

10. In what panel are child elements positioned in a sequential order from left to right or from top to bottom based on the orientation property?

StackPanel

WrapPanel

DockPanel

CanvasPanel

A WrapPanel is a panel in which child elements are positioned in a sequential order from left to right or from top to bottom based on the orientation property. This means that when the available space is filled in one direction, the elements wrap to the next line or column to continue the sequence. Unlike a StackPanel, which stacks elements in a single line, a WrapPanel allows for wrapping and reflowing of elements. Therefore, a WrapPanel is the correct panel for arranging child elements in a sequential order from left to right or from top to bottom.
