CarouselView-Xamarin表单：未显示数据

Question

I am trying to display data using carousel view in my forms application. I am not sure what am I missing but data is not getting populated, I have followed almost all available samples but still I have not found any success. Please help me get out of this problem:

I am using the following code in my xaml file:

<forms:CarouselView x:Name="listview" ItemsSource="postIdList" HeightRequest="200" Margin="5">
                    <forms:CarouselView.ItemTemplate>
                        <DataTemplate>
                            <ContentPage >
                                <StackLayout >
                                    <Label Text="{Binding .}" FontSize="20" TextColor="Black" HorizontalOptions="Center" />
                                </StackLayout>
                            </ContentPage>
                        </DataTemplate>
                    </forms:CarouselView.ItemTemplate>
                </forms:CarouselView>

And I am trying to populate the data in the following manner in .cs file:

List<string> postIdList = new List<string>
{
 "Carousel", "Carousel", "carousel"
};

listview.ItemsSource = postIdList;

If I give a background colour for carousal view I am able to see that colour, but text is not getting displayed. Please let me know my mistake.

Answer 1

In case of a ListView, you need an ObservableCollection instead of a List. Switch it around and see if it works?

Answer 2

On your XAML you are defining a <ContentPage> inside the <Datatemplate> . Replace the <ContentPage> with a <ViewCell> or a <Grid>

Here is a great example on how to use it, you need to keep in mind that CarouselView work like a ListView, it need to have a Datatemplate.
