I have just finished converting the control to silverlight one week away from Silverlight 2 beta 2 release date, so I have been waiting for it !
For people to be able to compare code (quite similar) and behavior between the WPF and the Silverlight control, I have kept the same codeplex project to host the whole solution.
So the address is still the same: http://www.codeplex.com/wpfbookcontrol and the project title has been renamed to ‘WPF and Silverlight BookControls’.
The silverlight control is a bit different:
- it’s a UserControl.
- the data connection natively proposes data virtualization.
The ItemsControl control does not allow data virtualization today. As I absolutely wanted it for this silverlight version, I voluntarily did not respect the ItemsSource behavior.
As a datasource, you have to provide a very simple interface:
public interface IDataProvider
object GetItem(int index);
The control will ask you on the fly for those two methods to dynamically retrieve needed pages.
In your application, just add a reference to SLMitsuControls.
Then use it in your xaml page: in this sample, I am using a static content to defines pages.
Width=”400″ Height=”300″ Loaded=”UserControl_Loaded”>
<Button Content=”Page 0″ Click=”Button_Click” />
<Button Content=”Page 1″ Background=”Green” Click=”Button_Click_1″ />
<Button Content=”Page 2″ Background=”Yellow” Click=”Button_Click” />
<Button Content=”Page 3″ Background=”Red” Click=”Button_Click_1″ />
<local:UCBook x:Name=”book” Margin=”50″ />
Then you must implement IDataProvider and call the SetData() method.
public partial class Page : UserControl, IDataProvider
private void UserControl_Loaded(object sender, RoutedEventArgs e)
#region IDataProvider Members
public object GetItem(int index)
public int GetCount()
private void Button_Click(object sender, RoutedEventArgs e)
private void Button_Click_1(object sender, RoutedEventArgs e)
Let me remind you that you can find a good dynamic sample in this flickr application:
