![]() The feature-rich ListView and GridView controls work out of box. It's important to understand the differences between these types of controls before you decide which one to use. ![]() Which collection control should you use? A Comparison with ItemsRepeater A common use case for GridView is a photo or product gallery. GridView works better for collections that have images as their focal point or whose items can be read from side-to-side or are not sorted in a specific order. Data is stacked horizontally until it fills a column, and then continues with the next row in the column. The GridView control presents a collection of items in rows and columns that can be scrolled vertically. Instead, consider using a DataGrid control. If you need to display collections in multiple columns or in a table-like format, you should not use ListView. A few common use cases for ListView include lists of messages and search results. ListView works better for items that have text as a focal point, and for collections that are meant to be read top to bottom (for example, alphabetically ordered). The ListView control displays data stacked vertically in a single column. ![]() That is, they all should perform the same action when they're clicked (for example, to open a link or browse). And both can be bound to existing dynamic data sources or to hard-coded data that's provided in the XAML itself or the code-behind.īoth controls are flexible to use in a variety of scenarios but, overall, they work best with collections in which all items have the same basic structure and appearance, as well as the same interaction behavior. Both are easy to implement and provide basic UI, interaction, and scrolling while being easily customizable. ListView and GridView controls provide many benefits as you work with collections. We may refer to classes like ListView or ListViewItem, but the List prefix can be replaced with Grid for the corresponding grid equivalent (GridView or GridViewItem). In this article, discussions about list view apply to both the ListView and GridView controls, unless otherwise specified. For example, it tends to be easier and more comfortable for people to reach a control when it’s located in the middle or bottom area of the display, so it’s especially important let people swipe to navigate back or initiate actions in a list row.ListView and GridView both derive from the ListViewBase class, so they have the same functionality but display data differently. Enable interactions that support the way people usually hold their device.Adapt seamlessly to appearance changes - like device orientation, Dark Mode, and Dynamic Type - letting people choose the configurations that work best for them.Help people focus on primary tasks and content by limiting the number of onscreen controls while making secondary details and actions discoverable with minimal interaction.To help your design feel at home in iOS, prioritize the following ways to incorporate these features and capabilities. ![]() Great iPhone experiences integrate the platform and device capabilities that people value most. iOS provides several features that help people interact with the system and their apps in familiar, consistent ways. People typically have multiple apps open at the same time, and they appreciate switching frequently among them. At other times, people can spend an hour or more browsing the web, playing games, or enjoying media. Sometimes, people spend just a minute or two checking on event or social media updates, tracking data, or sending messages. In addition, people often want apps to use their location and input from the device’s accelerometer and gyroscope, and they may also want to participate in spatial interactions.Īpp interactions. Multi-Touch gestures, onscreen keyboards, and voice control let people perform actions and accomplish meaningful tasks while they’re on the go. While people are interacting with the device, their viewing distance tends to be no more than a foot or two. People generally hold their iPhone in one or both hands as they interact with it, switching between landscape and portrait orientations as needed. iPhone has a medium-sized, high-resolution display.Įrgonomics. Using these characteristics and patterns to inform your design decisions can help you provide an app or game that iPhone users appreciate.ĭisplay. People depend on their iPhone to help them stay connected, play games, view media, accomplish tasks, and track personal data in any location and while on the go.Īs you begin designing your app or game for iOS, start by understanding the following fundamental device characteristics and patterns that distinguish the iOS experience.
