What property do we use for a TextBox control to display the vertical and horizontal scroll bar?

The properties used for a TextBox control to display the vertical and horizontal scroll bar are VerticalScrollBarVisibility and HorizontalScrollBarVisibility. The VerticalScrollBarVisibility property controls the visibility of the vertical scroll bar, while the HorizontalScrollBarVisibility property controls the visibility of the horizontal scroll bar.

Can we store the ContextMenu in Resource so that we can reuse it for various control on a form?
- A.
True
- B.

Correct Answer
A. TrueExplanation
In software development, particularly when using frameworks like WPF (Windows Presentation Foundation), you can indeed store a ContextMenu in a Resource dictionary or similar resource structure to facilitate reuse across multiple controls on a form. This approach promotes efficient code management and reduces redundancy by allowing the same context menu to be applied to various controls, enhancing maintainability and consistency across the user interface.Rate this question:

Correct Answer(s)
A. Resource dictionaries
B. Window
C. Container control
D. Application level (App.xaml)Explanation
Resources can be stored in various places in a software application. One common place is in resource dictionaries, which allow for centralized storage and easy access to resources like styles, templates, and localized strings. Resources can also be stored at the window level, where they are specific to a particular window or user interface element. Container controls, such as panels or grids, can also store resources that are specific to their child elements. Resources can also be stored at the application level, typically in the App.xaml file, where they are available throughout the entire application. Additionally, resources can be stored in an Azure service, which allows for remote access and scalability.Rate this question:
