WPF 包装XML 名单
原标题:WPF Binding XML List

我想对以下的《洗钱法》与《世界森林倡议》中的几种控制联系起来。

每一类名称都应与 com子的物品来源挂钩,然后,当一个类别被选定在 com子箱中时,我想将选定类别的产品清单与清单挂钩。

The XML:

<?xml version="1.0" encoding="utf-8" ?>
<Categories>
  <Category Name="Category1">
    <Products>
      <Product Name="Product 1"/>
      <Product Name="Product 2"/>
    </Products>
  </Category>
  <Category Name="Category2">
    <Products>
      <Product Name="Product 1"/>
      <Product Name="Product 2"/>
      <Product Name="Product 3"/>
    </Products>
  </Category>
</Categories>

等等。

将你的xml编成一个名为“类别.xml”的档案,这项工作应当做到......

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="40" />
        <RowDefinition />
    </Grid.RowDefinitions>

    <Grid.Resources>
        <DataTemplate x:Key="categoryTemplate" DataType="Category">
            <TextBlock Text="{Binding XPath=@Name}" />
        </DataTemplate>
        <DataTemplate x:Key="productTemplate" DataType="Product">
            <TextBlock Text="{Binding XPath=@Name}" />
        </DataTemplate>
    </Grid.Resources>

    <Grid.DataContext>
        <XmlDataProvider
            Source="Categories.xml" XPath="/Categories/Category" />
    </Grid.DataContext>

    <ComboBox
        x:Name="categoryComboBox"
        Grid.Row="0" Margin="8"
        IsSynchronizedWithCurrentItem="True"
        ItemsSource="{Binding}" ItemTemplate="{StaticResource categoryTemplate}" />

    <ListView
        Grid.Row="1" Margin="8"
        IsSynchronizedWithCurrentItem="True"
        ItemsSource="{Binding XPath=Products/Product}" ItemTemplate="{StaticResource productTemplate}" />
</Grid>
