Setter for Canvas.Left and Canvas.Top readwrite in WPF but not in Silverlight 4, why?
I have the following XAML, which works fine in WPF, but not in Silverlight 4
<ItemsPanelTemplate x:Key="ContentListBoxItemsPanelTemplate">
<Canvas/>
</ItemsPanelTemplate>
<DataTemplate x:Key="ContentListBoxItemTemplate">
<Border CornerRadius="15" Width="150" Margin="3" He开发者_如何学编程ight="300">
<Border.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Color="OrangeRed" Offset="1" />
<GradientStop Color="Brown" Offset="0" />
</LinearGradientBrush>
</Border.Background>
</Border>
</DataTemplate>
<Style TargetType="ListBoxItem">
<Setter Property="Canvas.Left" Value="{Binding Left}"/>
<Setter Property="Canvas.Top" Value="{Binding Top}"/>
</Style>
And then somewhere:
<ListBox Name="ContentList"
ItemTemplate="{StaticResource ContentListBoxItemTemplate}"
ItemsPanel="{StaticResource ContentListBoxItemsPanelTemplate}" />
If I try the same thing in Silverlight I get an exception saying that the setter cannot set a read only property, but I still want to achieve the same thing in Silverlight without code.
Any suggestions?
Silverlight does not support bindings in the value of the setter. David Anson has a great workaround here: http://blogs.msdn.com/delay/archive/2009/05/07/one-more-platform-difference-more-or-less-tamed-settervaluebindinghelper-makes-silverlight-setters-better.aspx
