[UWP Bug] sfListView group header size bug

[Ali Nsh]

Hi there everyone, 

Thanks for the great library for Xamarin Forms.
I noticed a little UI bug in UWP on sfListView control. After launching the app on Windows, the groups header size will render over the normal size but if you change the window size it will be fixed automatically. 

I attached the sample app to show the issue.

Hi Ali, 

 

The reported scenario occurs when setting the ItemSize in the SizeChanged event. Hence, we suggest you can overcome the reported scenario by setting the ItemSize as mentioned below, 

 

public partial class MainPage : ContentPage 

{ 

    public MainPage() 

    { 

        InitializeComponent(); 

        var lst = new List<TestModel>() 

        { 

            … 

        }; 

        listView.ItemsSource = lst; 

        if (Device.RuntimePlatform == Device.UWP) 

        { 

            listView.SizeChanged += (a, b) => DeviceDisplay_MainDisplayInfoChanged(null, new DisplayInfoChangedEventArgs(DeviceDisplay.MainDisplayInfo)); 

            listView.ItemSize = 100; 

        } 

    } 

 

    private void DeviceDisplay_MainDisplayInfoChanged(object p, DisplayInfoChangedEventArgs e) 

    { 

        if (Device.Idiom.HasFlag(TargetIdiom.Desktop)) 

        { 

            if (listView.Width < 0) return; 

            layout.SpanCount = (int)(listView.Width / e.DisplayInfo.Density / 100); 

            return; 

        } 

    } 

} 

 

Please let us know if you need further assistance.

Thanks, Setting the Item size on XAML or on the page Constructor solved the problem. 👍
