WPF DataTemplate Binding奇怪的问题

[zhujinqi2010]

大家好
我在DataTemplate中定义了一个Buton,然后给Button的Command调用一个路由命令，这样这个路由命令始终不会触发
但是我在DataTemplate外面定义一个Buton，同样的方式调用那个路由命令就可以了
不知道这是为什么！

<DockPanel>
<Canvas>
<thriple:ContentControl3D x:Name="Ctrl3D1">
</thriple:ContentControl3D>
<!--这里调用thriple:ContentControl3D.RotateCommand是可以触发的-->
<Button Command="thriple:ContentControl3D.RotateCommand"
CommandTarget="{Binding ElementName=Ctrl3D1}"
</Button>

</Canvas>


<local:NodeCoorator x:Name="NodeContor1" Graph="{Binding Path=.}">
<ItemsControl Background="DarkCyan" ItemsSource="{Binding Path=Nodes }">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<jas:DragCanvas/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>


<ItemsControl.ItemTemplate>
<DataTemplate>
<Border Width="30" Height="40">

<thriple:ContentControl3D x:Name="Ctrl3D2">
</thriple:ContentControl3D>

<!--这里调用thriple:ContentControl3D.RotateCommand就不能触发的-->
<Button Width="28" Height="18"
Command="thriple:ContentControl3D.RotateCommand"
CommandTarget="{Binding ElementName=Ctrl3D2}">
</Button>

</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>

</ItemsControl>
</local:NodeConnectionAdornerDecorator>
</DockPanel>

WPF还在我的学习计划中，现在只能帮忙顶了！

大家快来帮我顶顶啊，不能就这样沉了

this is because
<ItemsControl Background="DarkCyan" ItemsSource="{Binding Path=Nodes }">
you already bind an object, I guess

<Button Width="28" Height="18"
Command="thriple:ContentControl3D.RotateCommand"
CommandTarget="{Binding ElementName=Ctrl3D2}">
</Button>

the binding target is not included in Nodes
