Hi folks.

 

I am using the rad list view with grouping in my application. There are some cases when the list has empty groups (That's ok because according to the application's logic I can move items between groups). The problem is that the empty group it's not actually "Empty". It has a blank item which is not desirable behavior for me. I have a list view "item tapped" event which navigates the user to the details screen and when I tap on the empty group's item the application throws an exception because the list item is blank. I have attached a sample app according to this example and GIF files showing the issue.

 

Steps To Reproduce

 

  1. Download the zip file
  2. Open The app
  3. Add necessary Telerik dlls (Can't send dlls with the sample because of size)
  4. Tap on empty item


    Versions

    1. Xamarin Forms 5.0.0.1874
    2. Telerik Controls 2020.3 (latest)
    3. IDE Visual studio 2019

    The TabView control should support a swipe event to change the active item. Similar to the ListView with the IsItemSwipeEnabled-property.

    Currently TelerikLocalizationManager sets CurrentThread.CurrentCulture on Android and iOS taking into account the target device culture.

    If the developer has set the CurrentCulture on app level (different than the device culture), it is reset by our LocalizationManager.

    When using the __ItemStyle properties of RadListView, they are not being applied if the SelectionMode is set to None. It makes sense that the PressedItemStyle and SelectedItemStyle properties are not used, since they are not applicable if nothing can be selected. However, the ReorderItemStyle in particular should still be used.

     

    Example:

        public class ItemStyleNotAppliedExample : ContentPage
        {
            private readonly ListViewItemStyle WhiteBG = new ListViewItemStyle
            {
                BackgroundColor = Color.White
            };
    
            private readonly ListViewItemStyle YellowBG = new ListViewItemStyle
            {
                BackgroundColor = Color.Yellow
            };
    
            private readonly ListViewItemStyle RedBG = new ListViewItemStyle
            {
                BackgroundColor = Color.Red
            };
    
            private readonly ListViewItemStyle BlueBG = new ListViewItemStyle
            {
                BackgroundColor = Color.Blue
            };
    
            public ItemStyleNotAppliedExample()
            {
                BackgroundColor = Color.Gray;
    
                var items = new ObservableCollection<Item>
                {
                    new Item("Item 1"),
                    new Item("Item 2"),
                    new Item("Item 3"),
                    new Item("Item 4"),
                    new Item("Item 5"),
                };
    
                Content = new RadListView
                {
                    SelectionMode = SelectionMode.None,
                    IsItemsReorderEnabled = true,
                    ItemsSource = items,
                    ItemTemplate = new DataTemplate(typeof(ItemView)),
    
                    ItemStyle = WhiteBG,
                    PressedItemStyle = YellowBG,
                    SelectedItemStyle = RedBG,
                    ReorderItemStyle = BlueBG,
                };
            }
    
            private class Item
            {
                public string Name { get; }
    
                public Item(string name)
                {
                    Name = name;
                }

    Release 2020.3.1207 (R3 2020 minor release)

    if you look at the .nuspec file for the Telerik.UI.for.Xamarin.Documents.Flow package there is an entry in the 

    <framework> assemblies element;
    
    <frameworkAssembly assemblyName=”WindowsBase” targetFramework=””/ >
    

    This is what causes NuGet to drag the WindowsBase assembly in.

     we cannot build the iOS project - we get the following error.

    The type 'NotifyCollectionChangedAction' exists in both 'System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' and 'WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

    We are not referencing the WindowsBase assembly directly, but on analyzing the Nuget dependencies we found the following dependency chain;

    Telerik.UI.for.Xamarin (2020.3.1106.1) -> Telerik.UI.for.Xamarin.Documents.Flow (2020.3.1019) -> WindowsBase (Framework Assembly)

     it seems that WindowsBase (and PresentationCore which is also included) are not intended for Xamarin iOS or Android applications.

    We should consider splitting the Telerik.Xamarin.iOS.dll into separate DLLs so that the customers can reference only the controls they need.
