Hi.
I'm using the RadCarousel Control.
I have a List<BitmapImage> and when I add a BitmapImage to this list, I add a Image, with the BitmapImage as source to the RadCarousel.Items

But, instead of showing the actual image. It's showing a dot.

I've tryed to attach a sample project that reproduces my problem but I couldn't.
So follows my code:

XAML:
<Window x:Class="radcarouseltest.MainWindow" 
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        Title="MainWindow" Height="350" Width="525" 
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    <StackPanel> 
        <telerik:RadCarousel Name="carousel" FlowDirection="LeftToRight" VerticalAlignment="Center"  
                             HorizontalAlignment="Center" HorizontalScrollBarVisibility="Disabled"  /> 
        <Button Content="LoadImages" Click="Button_Click" /> 
    </StackPanel> 
</Window> 
 

CS:
using System; 
using System.Collections.Generic; 
using System.Windows; 
using System.Windows.Controls; 
using System.Windows.Media.Imaging; 
using Microsoft.Win32; 
 
namespace radcarouseltest 
    /// <summary> 
    /// Interaction logic for MainWindow.xaml 
    /// </summary> 
    public partial class MainWindow : Window 
    { 
        private const String ExtensionFilter = "(*.jpg)|*.jpg|(*.gif)|*.gif|(*.png)|*.png|(*.tif)|*.tif|(*.tiff)|*.tiff"
        private List<BitmapImage> imageList; 
        public MainWindow() 
        { 
            InitializeComponent(); 
            imageList = new List<BitmapImage>(); 
        } 
 
        private void Button_Click(object sender, RoutedEventArgs e) 
        { 
            OpenFileDialog dialog = new OpenFileDialog { RestoreDirectory = true, Filter = ExtensionFilter, Multiselect = true }; 
            if (dialog.ShowDialog() == true
            { 
                foreach (string fileName in dialog.FileNames) 
                { 
                    BitmapImage myImage = new BitmapImage(new Uri(fileName, UriKind.Relative)); 
                    imageList.Add(myImage); 
                    updateCarousel(); 
                    carousel.SelectedItem = carousel.Items[imageList.Count -1 ]; 
                     
                } 
            } 
        } 
 
        private void updateCarousel() 
        { 
            carousel.Items.Clear(); 
            foreach (BitmapImage img in imageList) 
            { 
                Image myImage = new Image(); 
                myImage.Source = img; 
 
                carousel.Items.Add(myImage); 
            } 
        } 
    } 
 

Thanks

Hello David Lino,

In your case it will be probably better (and easier) to use RadCarouselPanel. Otherwise, you will have to create DataTemplates in RadCarousel in order to show the images.
RadCarouselPanel has a Children property which is a collection of all children that are displayed by the panel and you can use the Add () method of Children to insert items. However, this collection accepts only UI Elements, thus obliging you to use Images, for example, instead of Bitmap Images. 
I am sending you a sample project that shows how to add Images in RadCarouselPanel. 

I hope that helps. 

PS: You are allowed to attach project files only when sending a support ticket. 

All the best,

The problem is that I want to use other features available only on RadCarousel, like SelectedItem property and so one.

Is there a way to insert Image on a radCarousel?

Can you give me a snippet of code showing how to create the DataTemplates  to show a single image like these?

Thanks

Hi David Lino,

I have re-coded the sample project so that it is using RadCarousel. I hope that meets your requirements. Still, if you have more questions, feel free to contact to us.
Furthermore, you may find additional information on how to style your carousel in our online documentation
