How to automatically scroll to bring the selected item into the view in .NET MAUI ListView (SfListView) ?
The .NET MAUI ListView (SfListView) allows you to automatically bring the selected item into the view when it changes at runtime by using the ScrollToRowIndex method.
C#
In the SfListView.PropertyChanged event, obtain the SelectedItem index from the DisplayItems, adjust the index based on the header and group header, and pass it to the ScrollToRowIndex method.
public class ListViewBehavior : Behavior<SfListView>
{
private SfListView ListView;
protected override void OnAttachedTo(SfListView bindable)
{
ListView = bindable;
...
ListView.PropertyChanged += ListView_PropertyChanged;
base.OnAttachedTo(bindable);
}
private void ListView_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
if (e.PropertyName == "SelectedItem")
{
ListView.Dispatcher.Dispatch(async () =>
{
await Task.Delay(100);
if (this.ListView.DataSource.DisplayItems.Count > 0)
{
var selectedItemIndex = ListView.DataSource.DisplayItems.IndexOf(ListView.SelectedItem);
selectedItemIndex += (ListView.HeaderTemplate != null && !ListView.IsStickyHeader && !ListView.IsStickyGroupHeader) ? 1 : 0;
(ListView.ItemsLayout as LinearLayout).ScrollToRowIndex(selectedItemIndex);
}
});
}
}
}
