Showing items as images in a WPF ListView

Question

So I have binded a List to a ListView where the List has items of type Album, where it has lots of properties including .Cover, which I is an image on disk. Well since I don't know what type of image is needed and how they have to be loaded (I only know using Image types for Winforms), I don't know the type yet.

Can someone show or post me a quick sample where it shows this sort of items being shown as images of a certain fixed size using their .Cover property?

In essence this would show:

1. What type .Cover should be
2. How to open images from disk for WPF (assuming it's different than Winforms image loading)
3. How to show them on a ListView as images of a certain fixed size, scaling the images if necessary

Answer 1

In xaml you'd define a DataTemplate in your Listview's ItemTemplate that uses an Image, binding it's Source property to a path on your file sysem.

In other words, Cover can be of type string, a file path. If you want to scale, a pretty simple way is a ViewBox, which scales all it contains. However, Image itself probably has options to do scaling.

Answer 2

1. ImageSource
2. ImageSource myImageSource = new BitmapImage(new Uri(@"file://C:... something.jpg"));

3. Specify a data template for the items in the ListView's ItemTemplate property:

   <Window.Resources>
       <DataTemplate x:Key="ItemTemplate">
           <StackPanel Orientation="Horizontal">
               <Image Width="10" Height="10" Stretch="Fill" Source="{Binding Cover}"/>
           <Label Content="{Binding Title}" />
           </StackPanel>
       </DataTemplate>
   </Window.Resources>
   
   
   <Grid x:Name="grid">
       <ListView ItemTemplate="{StaticResource ItemTemplate}" ItemsSource="{Binding Albums}" />
   </Grid>

Also getting xaml parsing error from this, anyone knows why, I really don't.

<Window x:Class="Cool.CoolWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="CoolWindow"
        Height="300"
        Width="300">

<Window.Resources>
    <DataTemplate x:Key="ItemTemplate">
        <StackPanel Orientation="Horizontal">
            <Image Width="10" Height="10" Stretch="Fill" Source="{Binding Cover}"/>
        <Label Content="{Binding Title}" />
        </StackPanel>
    </DataTemplate>
</Window.Resources>


<Grid x:Name="grid">
    <ListView ItemTemplate="{StaticResource ItemTemplate}" ItemsSource="{Binding Albums}" />
</Grid>
