The RadListView control is obsolete and will be removed in Q2 2026.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 Load on Demand

Updated on Mar 11, 2026

Loading a large data set on a mobile device has its challenges. One of the most popular approaches is using incremental data loading when the items need to be visualized. The ListView does this by using its load-on-demand functionality.

Configuration

The following properties control the LoadOnDemand feature:

IsLoadOnDemandEnabled(bool)—Used to enable the load on demand mechanism of the ListView.
IsLoadOnDemandActive (bool)—Used to control the loading indicator that is rendered when the data is retrieved asynchronously. Set it to True when an async operation is running and items are loading. Set it to False when the items are loaded.
LoadOnDemandMode—Used to set the loading mode. You can select between:
- Automatic—The data is requested automatically when you scroll near the end of the ListView.
- Manual—A button is rendered at the end of the ListView. The data is requested explicitly by pressing the button.

Methods to Load Data on Demand

Three options to load the data on demand, regardless of whether you use the Automatic or Manual loading mode:

Create a ListViewLoadOnDemandCollection instance as a source and pass it to the ListView Items Source property.
Subscribe to the LoadOnDemand event and add the loaded data to the source.
Use the LoadOnDemand User Command and add the loaded data to the source.

All three approaches for loading items on demand in the ListView work with both the automatic and manual LoadOnDemandMode.

Using LoadOnDemandCollection

To load items on demand, you can use the ListViewLoadOnDemandCollection and set it as an ItemsSource for the ListView. The ListViewLoadOnDemandCollection accepts an action in the constructor and this action is later executed by the ListView in a non-UI thread when new items are requested.

Using LoadOnDemand Event

Another way to handle loading more items is to use the LoadOnDemand event. This event is raised on a UI thread, so in the event handler you can add items right away or asynchronously:

In case the data is available right away, add the items to the ListView ItemsSource in the LoadOnDemand event handler.
If you require an async operation, set the IsLoadOnDemandActive property of the ListView to True. This notifies the ListView that it must display the loading indicator. Then an async call can be initiated to get the data. When the new items are ready, you must set the IsLoadOnDemandActive property to False again to notify the ListView that the load-on-demand operation is completed.

Using LoadOnDemand Command

This approach is similar to using the LoadOnDemand event, but in this case, the load-on-demand is handled in the ViewModel through the LoadOnDemandUserCommand exposed by the ListView. In the Execute method of the command, you can add items right away or asynchronously:

If the data is available right away, add the items to the ListView ItemsSource in the LoadOnDemand command Execute method.
If you require an async operation, set the IsLoadOnDemandActive property of the ListView to True. This notifies the ListView that it must display the loading indicator. Then an async call can be initiated to get the data. When the new items are ready, you must set the IsLoadOnDemandActive property to False again to notify the ListView that the load-on-demand operation is completed. You can control the behavior of IsLoadOnDemandActive through a binding to a boolean property in the ViewModel class.

Advanced Options

You can also use the ListView options for performing advanced control over its load-on-demand feature.

Control the Number of Pre-loaded Items

This feature works in conjunction with the LoadOnDemandMode.Automatic mode of the ListView. You can control the minimum number of items loaded ahead through ListView LoadOnDemandBufferItemsCount property. By default, the property is for 10 items. When ListView requests an item in the buffer, it will trigger a new loading batch.

Change the Appearance of the Manual Load Button

This feature works in conjunction with the LoadOnDemandMode.Manual mode of the ListView. You can control the content of the Load More Button through the LoadOnDemandItemTemplate property.

Change the Appearance of the Manual Loading Indicator

This feature works in conjunction with the LoadOnDemandMode.Manual mode of the ListView.

You can control the content of the Loading Indicator through the LoadingOnDemandItemTemplate property.
