Question

I am creating a WPF app with a list box that I am binding to project names. As a decorative element, I want to place a small icon next to each item in the list, similar to the way Outlook does in its Personal Folders list. For starters, I am going to use the same image for all items in the list.

Here is the markup that I’ve got so far (I’ll move it to a resource dictionary after it’s working):

<ListBox.Resources>
    <ImageBrush x:Key="ProjectIcon" ImageSource="Images/project.png" />
</ListBox.Resources>
<ListBox.ItemTemplate>
    <DataTemplate>
        <StackPanel Orientation="Horizontal">
            <Image Source="{StaticResource ProjectIcon}"/>
            <TextBlock Text="{Binding Path=Name}" />
        </StackPanel>
    </DataTemplate>
</ListBox.ItemTemplate>

I’ve got an error in the image resource, but I’m not sure how to fix it. Any suggestions? Thanks.

The Source property of an Image is of type ImageSource not ImageBrush. The following should work:

<ListBox.Resources>
    <BitmapImage x:Key="ProjectIcon" UriSource="Images/project.png" />
</ListBox.Resources>
<ListBox.ItemTemplate>
    <DataTemplate>
        <StackPanel Orientation="Horizontal">
            <Image Source="{StaticResource ProjectIcon}"/>
            <TextBlock Text="{Binding Path=Name}" />
        </StackPanel>
    </DataTemplate>
</ListBox.ItemTemplate>
