Description

I want the ManualLoadOnDemandTemplate of the CollectionView for .NET MAUI to disappear when there are no more items to load. The template currently remains visible even after all data has been loaded.

This knowledge base article also answers the following questions:

• How can I disable the ManualLoadOnDemandTemplate in CollectionView for .NET MAUI?
• What property controls the visibility of the ManualLoadOnDemandTemplate in CollectionView?
• How do I stop the load-on-demand feature in CollectionView for .NET MAUI?

Solution

To remove or hide the ManualLoadOnDemandTemplate when no more items need to be loaded, set the IsLoadOnDemandEnabled property of the CollectionView to false. This property controls whether the load-on-demand functionality is active. Disabling it hides the ManualLoadOnDemandTemplate.

Here is an example:

1. Define the ViewModel

csharp

public partial class LoadOnDemandCollectionViewModel : NotifyPropertyChangedBase
{
    private bool isEnabled = true;

    public LoadOnDemandCollectionViewModel()
    {
        this.Items = new LoadOnDemandCollection<Person>(this.LoadMoreItems);

        for (int i = 0; i < 20; i++)
        {
            this.Items.Add(new Person { Name = "Person " + i, Age = i + 10 });
        }
    }

    public LoadOnDemandCollection<Person> Items { get; set; }

    public bool IsEnabled
    {
        get => this.isEnabled;
        set => this.UpdateValue(ref this.isEnabled, value);
    }

    private IEnumerable LoadMoreItems(CancellationToken cancellationToken)
    {
        List<Person> newItems = new List<Person>();
        int count = this.Items.Count;

        // Simulate a limit for loading more items
        if (count >= 30)
        {
            this.IsEnabled = false; // Disable load-on-demand
            return null; // No more items to load
        }

        for (int i = count; i < count + 10; i++)
        {
            newItems.Add(new Person { Name = "Person " + i, Age = i + 10 });
        }

        return newItems;
    }
}

2. Bind the IsLoadOnDemandEnabled property of the RadCollectionView to a property in your ViewModel, such as IsEnabled:

xml

<telerik:RadCollectionView x:Name="listView"
                           ItemsSource="{Binding Items}"
                           DisplayMemberPath="Name"
                           LoadOnDemandMode="Manual"
                           IsLoadOnDemandEnabled="{Binding IsEnabled, Mode=TwoWay}" />
