将集合绑定到StackPanel

我试过了…但我认为这不是正确的方法。我以前用DataTemplated做过这种想法。。如果我错了,请纠正我。

public class MockModel
{
   public ObservableCollection<MockNode> Nodes;

   public MockModel()
   {
      Nodes = new ObservableCollection<MockNode>();
   }
}

public class MockNode
{
   public MockNode()
   {
   }

   private string itemname;
   public string ItemName
   {
      get { return this.itemname; }
      set { this.itemname = value; }
   }
}

// Init Model
MockModel myModel = new MockModel();

for (int i = 0; i < 4; i++)
{
   MockNode mn = new MockNode();
   mn.ItemName = String.Format("Node {0}", i);
   myModel.Nodes.Add(mn);
}
// Set DataContext for StackPanel
Stack.DataContext = myModel.Nodes;

还有xaml

<StackPanel x:Name="tStack">
   <ItemsControl ItemsSource="{Binding Nodes}">
      <ItemsControl.Template>
         <ControlTemplate>
            <Button Content="{Binding ItemName}"/>
         </ControlTemplate>
      </ItemsControl.Template>
   </ItemsControl>
</StackPanel>

它确实绑定,但我只得到一个按钮而不是4个按钮。。。。

思想?
