Question

I m 试图将数据网约束为xml:

<StackPanel.DataContext>
<XmlDataProvider Source="bill.xml" XPath="/Foods/Food"/>
</StackPanel.DataContext>

<DataGrid Width="190" Height="200" HorizontalAlignment="Center" VerticalAlignment="Top" Foreground="Black" ItemsSource="{Binding}">

<DataGrid.Columns>
<DataGridTextColumn Header="Quantity" FontSize="12" Binding="{Binding XPath=/Foods/Food/Quantity}" />
<DataGridTextColumn Header="Item" FontSize="12" Binding="{Binding XPath=/Foods/Food/Item}"/>
<DataGridTextColumn Header="Price" FontSize="12" Binding="{Binding XPath=/Foods/Food/Price}"/>
<DataGridTextColumn Header="P" FontSize="12" Binding="{Binding XPath=/Foods/Food/P}"/>
<DataGridTextColumn Header="C" FontSize="12" Binding="{Binding XPath=/Foods/Food/C}"/>          
</DataGrid.Columns>

</DataGrid>

XML:

<?xml version="1.0" encoding="utf-8" ?>
    <Foods>
      <Food>
        <Quantity>1</Quantity>
        <Item>SMALL COFFEE</Item>
    <Price>0.95</Price>
    <P>N</P>
    <C>1</C>
      </Food>
    <Food>
        <Quantity>1</Quantity>
        <Item>CHEESE CAKE</Item>
    <Price>4.50</Price>
    <P>N</P>
    <C>1</C>
      </Food>
    <Food>
        <Quantity>1</Quantity>
        <Item>SPAGHETTI</Item>
    <Price>13.50</Price>
    <P>N</P>
    <C>1</C>
      </Food>

    </Foods>

数据显示没有。

我是否误解了什么?

Answer 1

页: 1 因此,你无需在您的约束力中说明<代码>XPath的那部分内容。因此:

<DataGridTextColumn Header="Quantity" FontSize="12" Binding="{Binding XPath=Quantity}" />

Answer 2

我有同样的问题。添加xmlns=”对我来说是解决问题的。

可能需要在食品中添加xmlns=”。

不

用途
