        <local:HistoryViewModel/>
    </ContentView.BindingContext><telerikInput:RadListPicker x:Name="typeListPicker" Placeholder="Select Type" HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand" HeightRequest="40" WidthRequest="200" Margin="5"
                          ItemsSource="{Binding TypesItems}"
                          DisplayMemberPath="Value"
                         SelectedItem="{Binding Types, Mode=TwoWay}"><telerikInput:RadListPicker.ItemTemplate><DataTemplate><Label Text="{Binding Value}"
                         HorizontalTextAlignment="Center"
                         VerticalTextAlignment="Center"/></DataTemplate></telerikInput:RadListPicker.ItemTemplate></telerikInput:RadListPicker>

 private SchedulerTypeItem _types; 
  public HistoryViewModel()
        {
     
InitTypesItem();
}

   private void InitTypesItem()
        {
            TypesItems = new ObservableCollection<TypesItem>()

            {
              new TypesItem { Value = "Push" },
              new TypesItem { Value = "Pull" },
             };
        }

  public SchedulerTypeItem Types
        {
            get
            {
                return _types;
            }
            set
            {
                if (_types != value)

[Solved] RadEntry doesn't have the IsPassword property in Maui?

I am investigating the use of UI for .NET Maui and am looking for a password entry control, it seems like RadEntry doesn't support the IsPassword property that I would expect. Is this a planned feature ?

<telerikInput:RadEntry x:Name="txtPassword" Grid.Row="2" WatermarkText="Password" />

MAUI - Error

Hi,

I get this error.

To project itself ?

To telerik controls ?

How is can be solved ?

How do I setup MAUI RadListView ItemTemplate, ItemsSource in C# instead of XAML

All my efforts so far generate errors outside my code.

Here is sample (EntityEntry is a struct with Name and Id properties, Entries is a list of them):

            foreach(string key in dictionary.Keys)
            {
                Entries.Add(new EntityEntry { Name = key, Id = dictionary[key] });
            }

            Grid grid = new Grid();
            Label label = new Label
            {
                FontSize = 15D,
                FontAttributes = FontAttributes.Bold,
            };
            label.SetBinding(Label.TextProperty, "Name");
            grid.Children.Add(label);
            ListViewTemplateCell lt = new ListViewTemplateCell() { View = grid};
            DataTemplate dt = new DataTemplate(() => lt.View);

            EntitiesLv = new RadListView
            {
                Background = Colors.PaleTurquoise,
                HorizontalOptions = LayoutOptions.Fill,
                IsItemsReorderEnabled = false,
                ItemTemplate = dt,
                ItemsSource = Entries,
                LayoutDefinition = new ListViewGridLayout
                {
                    HorizontalItemSpacing = 5D,
                    VerticalItemSpacing = 5D
                },
                LoadOnDemandBufferItemsCount = 5,
                LoadOnDemandMode = LoadOnDemandMode.Automatic,
                Margin = new Thickness(10, 10),
                SelectionMode = SelectionMode.Single,
                VerticalOptions = LayoutOptions.Fill,
                VerticalScrollBarVisibility = ScrollBarVisibility.Default,
            };
            EntitiesLv.GestureRecognizers.Add(new TapGestureRecognizer { Command = ListTapped, NumberOfTapsRequired = 1 });
            EntitiesLv.SelectionChanged += EntitiesLvOnSelectionChanged;

Error occurs if ItemTemplate and ItemsSource are both set, but not if just one is.

All help appreciated.
