What’s New In Silverlight 3 – Element Binding
In Silverlight 3 you can now use one User Interface element as the binding object for another. This can greatly simplify your code. For example, if you wish to display the value of a slider in a text box, there is no need to create a data object to mediate their connection; you can bind the text box directly to the slider:
1: <Slider x:Name="sUnBound"
2: LargeChange="10"
3: Maximum="100"
4: SmallChange="1"
5: Value="50"
6: VerticalAlignment="Bottom" />
7:
8: <TextBlock x:Name="valueFromElement"
9: Text="{Binding Value, Mode=OneWay, 10: ElementName=sUnBound}" />
Putting this in a new application will create a slider and a TextBlock and will bind the latter to the former and no code-behind is required at all.
Much more on this in the Mini-tutorial on Element Binding.
