New WPF Features: Binding to Dynamic Objects
This is part of a series on New WPF Features
C# 4.0 allows creation of dynamic objects which is useful when you are interacting with dynamic languages. If you are unfamiliar with the dynamic concept take a quick look at this blog entry
So back to WPF. We support binding to dynamic objects.. woohoo... To begin with you need to create the dynamic object (see attached proj)
<Window.Resources>
<local:DynamicObjectClass x:Key="MyDynamicObject" />
</Window.Resources>
<StackPanel Name="BindPanel" DataContext="{StaticResource MyDynamicObject}">
<TextBox Text="{Binding Path=A}"/>
<TextBlock Text="{Binding Path=B.C}" />
<TextBox Text="{Binding Path=[(x:Int32)0]}"/>
In the loaded event , we can then set values
dynamic dynamicObj = BindPanel.DataContext ;
dynamicObj.A = "Simple Binding";
dynamicObj.B = new DynamicObjectClass();
dynamicObj.B.C = "Nested Prop Binding";
dynamicObj.AddItem("item 0");
dynamicObj[0] = "Indexer Binding";
