Answer 1

Here is how to set the SelectedItem with the ItemSelected event handler. Add the eventhandler to your XAML file and then add the event handler to its code behind.

<!-Page.xaml-/>
<ListView x:Name="myList"   
    ItemsSource="{Binding Items}"
    SelectedItem="{Binding SelectedItem}"
    HasUnevenRows="true"
    ItemSelected="OnItemSelected"/>

// in your code behind Page.xaml.cs
void OnItemSelected(object sender, SelectedItemChangedEventArgs e)
{
   if (sender!= null && sender is ListView listview)
   {
       if (e != null)  e.SelectedItem = null;
   }
}

Answer 2

This is a solution:

 if (e.SelectedItem == null)
        {
            return;
        }
((ListView)sender).SelectedItem = null;
