The RadListView control is obsolete and will be removed in Q2 2026. Use the RadCollectionView control instead. The RadCollectionView is a complete, ground-up rewrite of the ListView. The RadCollectionView offers improved performance, enhanced features, and a modernized approach to managing lists of data. The RadCollectionView incorporates all of the ListView's key features. More about the differences between both components and how to migrate to the new RadCollectionView is available in the Migrating the Telerik .NET MAUI RadListView to RadCollectionView article.

.NET MAUI ListView Delegate Group Descriptor

Updated on Mar 11, 2026

DelegateGroup descriptor enables you to group by a custom key (for example, some complex expression combining two or more properties) instead of being limited by the value of a single property. This descriptor exposes the following properties:

• KeyExtractor—Defines the (Func<object, object) delegate which returns the property to retrieve the group key for each data item.
• SortOrder—Defines the sort order in each group to Ascending or Descending.
