Vertical ScrollBar

With R1 2020 SP release RadListView provides the option to set the visibility of its vertical scrollbar according to your preferences:

  • VerticalScrollBarVisibility(Xamarin.Forms.ScrollBarVisibility): Specifies whether the vertical scrollbar will be visualized. By default it is set to ScrollBarVisibility.Default which means the scrollbar behavior depends on the target platform.

Here is a quick snippet on how you can set it to ScrollBarVisibility.Always:

<telerikDataControls:RadListView x:Name="listView" 
                                 VerticalScrollBarVisibility="Always" />
var listView = new RadListView();
listView.VerticalScrollBarVisibility = ScrollBarVisibility.Always;

Programmatic Scrolling

RadListView exposes the following method for programmatic scrolling to a specific data item:

  • ScrollItemIntoView(object item): Attempts to bring the specified data item into the view.


Here is the definition of the ListView control:

        <RowDefinition Height="Auto"/>
        <Button Clicked="ScrollItemIntoViewClicked" Text="ScrollItemIntoView"/>
        <Label x:Name="label"/>
    <telerikDataControls:RadListView x:Name="listView" Grid.Row="1" ItemsSource="{Binding Items}"/>

use the following code to create a simple data for the ListView component:

private Random rnd;
public ObservableCollection<string> Items { get; set; }
public ProgrammaticScrolling()

    this.rnd = new Random();
    this.Items = new ObservableCollection<string>();

    for (int i = 0; i < 100; i++)
        this.Items.Add("Item " + i);

    this.BindingContext = this;

Create a method called ScrollToItem and inside this method use ScrollItemIntoView to navigate to a concrete item:

private void ScrollItemIntoViewClicked(object sender, EventArgs e)
private void ScrollToItem()
    var item = this.Items[rnd.Next(this.Items.Count - 1)];
    this.label.Text = "Scrolled to: " + item;

And the end result:
