    It could be that you put a label in the middle (in invisible mode), at the moment of loading the information if nothing was found, shown as visible (label) and the Liistview as invisible

    I think yes. You could have a label with "EMPTY LIST" that has IsVisible binded to ListViewItem.Count (Also listview should have the IsVisible property binded with ListViewItem.Count...), then, if Count > 0, Label is not visible (and list is visible). if Count == 0, Label is visible and ListView is not visible... hope to be clear also without a line of code...

    @AlessandroCaliaro I understand the logic but can you give an example?

    ok @ScottJean-Philippe

    https://github.com/acaliaro/TestBindingWithListView

    here you can find a demo (born for other things but added your problem).

    You found 3 items in your listview. If you press "Description", you will popup a dialog. Select Delete so you delete the row. Delete all rows. The "The list is empty" label will appears.

    Let me know Have a nice day

    Hey guys... This thread is old, but maybe it'll help someone: What I end up doing was

    if ((MyList.ItemsSource as List<MyType>).Count == 0)
                    {
                        MyList.IsVisible = false;
                        EmptyMessage.IsVisible = true;
                    }
    

    Where the ListView MyList and the Label EmptyMessage defined in the xaml, and MyType is the type of the items used to create MyList.

    It works perfectly fine for me :smile:

    Is anybody looking for more MVVM based implementation, here is how you do: Have one HasItems property in your ViewModel which contains the list. Set the HasItems = Items.Any(); whenever refreshing the list items, bind the IsVisible of list directly to HasItems and inversely bind the label of StackLayout with HasItems. <ListView x:Name="ItemsListView" IsVisible="{Binding HasItems}" And here is empty view: <StackLayout IsVisible="{Binding HasItems, Converter={StaticResource cnvReveresBoolConverter}}" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">

    cnvReveresBoolConverter is my custom converter which reverses the bool value, you can use data triggers.

    <StackLayout IsVisible="False"> <StackLayout .Triggers> <DataTrigger TargetType="StackLayout " Binding="{Binding HasItems}" Value="False"> <Setter Property="IsVisible" Value="True"/> </DataTrigger> .......
