Background

Business requirements

In this section, you will see one or more sets of questions with the same scenario and problem. Each question presents a unique solution to the problem, and you must determine whether the solution meets the slated goals. Any of the solutions might solve the problem. It is also possible that none o' the solutions solve the problem.

Application structure

Once you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appe.ir in the review screen.

The timeline element of the app has the following layout requirements:

• the timeline must adapt to the screen size and orientation of the device.

• The timeline size must dynamically change if the window containing the content is resized by the user.

• The user must be able to scroll through the timeline horizontally when the device is in landscape mode.

• The user must be able to scroll through the timeline vertically when the device is in portrait mode.

• The timeline must begin scrolling as soon as a scroll is detected. Scrolling must continue for a short distance after the scroll input has stopped.

• Scroll bars or panning controls must always be visible.

The following image depicts the layout for the timeline section of the app when the device is using landscape orientation:

the following image depicts the layout tor the timeline section of the app when the device is using portrait orientation:

The content element of the app has the following layout requirements:

When a user selects an item on the timeline, the details for that item must display beneath or to the right of the timeline

• The content section must display one page of information. The element must be a child of the selected item in the timeline.

Layout Requirement:

You identify the following layout requirements:

General

• All user interface (Ul) elements must continuously scale when a user resizes the window.

• UI controls must be smaller and spaced closet together if there is a mouse 01 stylus available

• UI controls must be larger and spaced farther apart if the device supports touch and there is no mouse or pointer available

Timeline

• The timeline must be displayed In a horizontal layout when the device is in a landscape orientation or When the horizontal width is greater than the vertical height.

• The timeline must be displayed in a vertical layout when the device- is m a portrait orientation or when the vertical height is greater than the horizontal width.

• Each item in the past must be linked to the next item in the future

• User must be able to scroll from past events to future events 01 from future events to past events.

• The app must only allow one level of detail to be linked to each item in the timeline

New Tab:

You must optimize the app using the following guidelines:

• You must minimize the lime n takes to display content when an item on the timeline is selected.

• The app must respect memory and resource constraints for all devices.

XML coding style:

All code and markup must conform to the following style guidelines:

• Use resource dictionaries for styles that are used more than once.

• Limit the use of nested panels.

• Use built-in properties of existing panels instead of using separate style objects.

• Use the navigation structure that best models the data without exceeding the requirements of the app.
