In Windows 8, when the data item in a selected GridViewItem is replaced, the SelectedIndex value is not cleared. When incremental loading is supported, you can use these members to control data loading: DataFetchSize, IncrementalLoadingThreshold, IncrementalLoadingTrigger, LoadMoreItemsAsync. Incremental loading virtualization is supported when the data source implements the ISupportIncrementalLoading interface. Virtualization requires both of these interfaces. C# or Visual Basic apps should implement INotif圜ollectionChanged and (not IList.Visual C++ component extensions (C++/CX) apps should implement IObservableVector.Random access virtualization is supported when the data source implements the appropriate interfaces, which vary depending on the programming language: GridView supports data virtualization to improve performance with large data sets. When you set the Padding property on a GridView control, the value for right padding is ignored only the values for left, top, and bottom padding are applied. SelectionMode = None, IsItemClickEnabled = True SelectionMode = Extended, IsItemClickEnabled = False SelectionMode = Multiple, IsItemClickEnabled = False SelectionMode = Single, IsItemClickEnabled = False SelectionMode = None, IsItemClickEnabled = False Use this property to get the selected item: This table shows the ways a user can interact with a GridView, and how you can respond to the interaction. You can also change the GridView interaction mode to make items respond to a user click like a button instead of being selected. You can set the SelectionMode property to a ListViewSelectionMode enumeration value to allow multi-selection or to disable selection. Seeīy default, a user can select a single item in a GridView. If your app depends on the previous behavior, you can override pen scrolling and revert to the previous behavior.

If you use the GridView to display large sets of data, see Optimize ListView and GridView for tips to maintain a smooth and responsive user experience. In this example, the template is applied to the first item, but not the second item. If you populate the Items collection directly, the ItemTemplate is applied only if the item is not a GridViewItem. If you populate the GridView by setting the ItemsSource property, the ItemTemplate is applied to every item. For common templates you can use in your app, see Item templates for GridView. You assign the DataTemplate to the ItemTemplate property of the GridView. The controls in the layout can be bound to properties of a data object, or have content defined inline. To specify exactly how items in the GridView are displayed, you create a DataTemplate to define the layout of controls used to display an individual item. To populate the view, add items to the Items collection, or set the ItemsSource property to a data source.īy default, a data item is displayed in the GridView as the string representation of the data object it's bound to. GridView is an ItemsControl, so it can contain a collection of items of any type. It's often used when you need to show a rich visualization of each item that takes more space, such as a photo gallery. Data is stacked horizontally until it fills the columns, then continues with the next row. Use a GridView to display a collection of items in rows and columns that can scroll vertically.

In the following example, the corners of items in every GridView throughout the app are rounded to 5px. Public sealed partial class MainPage : Page The HidesIfEmpty property is set to true to hide any empty groups. The GroupStyle.ContainerStyle is used to add a border around each group, and set its minimum size and margins. The GroupStyle.Panel specifies how individual items are arranged within each group. The ItemsPanel specifies how the groups are arranged in the GridView. The appearance of individual items in each group is defined by the ItemTemplate. Here, a GridView is bound to a grouped CollectionViewSource named cvsProjects. Get the app from the Microsoft Store or get the source code on GitHub.
