WP7 WrapPanel和MVVM

Question

Is there a way to populate the Silverlight toolkit's WrapPanel via binding to an ObservableCollection ? All the examples I've seen so far, including the toolkit example itself, either populate the WrapPanel programmatically or by explicitly adding each item in XAML.

Thanks for your help!

EDIT : Following Geert van Horrik's advice I tried using an ItemsControl to load the WrapPanel via binding. This is the XAML:

<ScrollViewer VerticalScrollBarVisibility="Auto"
              Height="440"
              Margin="0,12,0,0">

  <ItemsControl ItemsSource="{Binding SelectionContent}">
    <ItemsControl.ItemTemplate>
      <DataTemplate>

        <Border BorderThickness="1"
                CornerRadius="4"
                BorderBrush="{Binding BorderBrush}">

          <toolkit:GestureService.GestureListener>
            <toolkit:GestureListener Tap="OnWrapPanelTapped"
                                     DoubleTap="OnWrapPanelDoubleTapped" />
          </toolkit:GestureService.GestureListener>

          <Image Source="{Binding ImageSource}"
                 MaxHeight="48"
                 MaxWidth="48"
                 Margin="16" />
        </Border>

      </DataTemplate>
    </ItemsControl.ItemTemplate>

    <ItemsControl.ItemsPanel>
      <ItemsPanelTemplate>
        <toolkit:WrapPanel />
      </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
  </ItemsControl>
</ScrollViewer>

SelectionContent is an ObservableCollection present in this UserControl 's code behind. It consists of SelectionItem object, which implements INotifyPropertyChanged and exposes 2 public properties - ImageSource and BorderBrush .

I'm setting the DataContext for the UserControl in its constructor to SelectionContent . But this isn't working and the WrapPanel does not display anything.

You should use an ItemsControl. Then, you can set the WrapPanel as items panel.

<ItemsControl ItemsSource="{Binding MyItemsSource}">
  <ItemsControl.ItemsPanel>
    <WrapPanel />
  </ItemsControl.ItemsPanel>
</ItemsControl>
