Xamarin.Forms CollectionView
Introduction
The CollectionView
is a flexible and performant view for presenting lists of data using different layout specifications.
Data
A CollectionView
is populated with data by setting its ItemsSource
property to any collection that implements IEnumerable
. The appearance of each item in the list can be defined by setting the ItemTemplate
property to a DataTemplate
.
Layout
By default, a CollectionView
will display its items in a vertical list. However, vertical and horizontal lists and grids can be specified.
Selection
By default, CollectionView
selection is disabled. However, single and multiple selection can be enabled.
Empty views
In CollectionView
, an empty view can be specified that provides feedback to the user when no data is available for display. The empty view can be a string, a view, or multiple views.
Scrolling
When a user swipes to initiate a scroll, the end position of the scroll can be controlled so that items are fully displayed. In addition, CollectionView
defines two ScrollTo
methods, that programmatically scroll items into view. One of the overloads scrolls the item at the specified index into view, while the other scrolls the specified item into view.
Grouping
CollectionView
can display correctly grouped data by setting its IsGrouped
property to true
.
