那一行是有錯誤？什麼樣的錯誤？ –

開關的鑰匙和周圍的數據類型的字段，錯誤是說你已經添加2個資源，爲相同的數據類型。

<DataTemplate x:Key="Milestones" DataType="Milestone"> 
</DataTemplate> 

<DataTemplate x:Key="View" DataType="Milestone"> 
</DataTemplate>

感謝它的工作，但是，我很困惑與所有的鍵和DataTpe。有人可以指導我如何加載正確的和在哪裏。這裏是我的xml <里程碑名稱= 「1987」> <簡介> <前言> –

我已經按照Andy的指示和頁面加載進行了更改，但列表框是空白的。下面是代碼和XML

<Grid.Resources> 
     <!-- The DataTemplate for a <Milestone> element. --> 
     <XmlDataProvider Source="Data/Decade2.xml" XPath="Milestones" x:Key="AllMilestones" IsInitialLoadEnabled="True"/>

       <TextBlock Text="{Binding [email protected]}" /> 

     </DataTemplate>

      <StackPanel FlowDirection="LeftToRight" Orientation="Horizontal"> 
       <Image Source="{Binding XPath=./Media}" Width="250" Height="250" Grid.Column="0" /> 
       <Canvas Grid.Column="1" Background="#0071bc" Height="Auto" >
