This method works better if ListView or GridView is going to hold custom class objects, as shown in the following examples. To populate a ListView or GridView control from a data source, you set its ItemsSource property to a collection of data items. You would ordinarily use a ListView or GridView to display data from a source such as a database or the internet. Method 2: Add items by setting the ItemsSource property Add the ListView to a parent container in the visual tree (which you created in the corresponding XAML file).īoth of these options produce the same list view, as shown here: Create a new ListView and add content. Method 1: Add items to the Items collection You would ordinarily add items through XAML if you have a small number of items that don't change and are easily defined, or if you generate the items in code at runtime. You can add items to the ListView or GridView Items collection by using either XAML or code to yield the same result. Add items to a ListView or GridView control You use the ItemsSource property for this purpose. However, it's more common for the items in a list to come from a dynamic source, such as a list of books from an online database. Many of the examples in this article populate the Items collection directly for the sake of simplicity. If you set the ItemsSource property and you add an item to the Items collection in code, an exception is thrown. If you set the ItemsSource property and you add an item in XAML, the added item is ignored. You can use either the Items or ItemsSource property to populate the list, but you can't use both at the same time. Learn more about ItemsRepeater by reading its Guidelines and API documentation. Use ItemsRepeater if you have a highly customized UI that you can't create by using either ListView or GridView, or if your data source requires different behavior for each item. It doesn't have the same built-in features and functionality as ListView and GridView, so you'll need to implement any necessary features or interactions. The ItemsRepeater control also is used to display collections, but it's designed as a building block for creating a custom control to suit your particular UI requirements. Each has its own built-in UI and UX and is designed to display nearly any type of collection as is. They require no customization, but they can be customized easily. 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. ListView and GridView both derive from the ListViewBase class, so they have the same functionality but display data differently.
