Question

好的。这是第一次，我有一个非常基本的问题。

我有一个外部XML存储过的地方。让我们说桌面。

XML看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>

-<Incidents>
    <Incident>    
        <IncidentNumber>4</IncidentNumber>    
        <Summary>4</Summary>    
        <Reason1>4</Reason1>    
        <Reason2>4</Reason2>    
        <Reason3>4</Reason3>    
    </Incident>    
</Incidents>

它有更多＆＃34;事件＆＃34; s，但我想缩短它。

在XAML中，我试图在ListView上显示这些数据，如下所示：

<ListView x:Name="lst_data" Height="290" Margin="10,29,10,0" VerticalAlignment="Top" Width="484" BorderThickness="1" BorderBrush="#FFDADADA" HorizontalAlignment="Center" ItemsSource="{Binding Source={StaticResource IncidentProvider}}">
            <ListView.View>
                <GridView>
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=//Incident/IncidentNumber}" Header="Number"/>
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=//Incident/Summary}" Header="Summary"/>
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=//Incident/Reason1}" Header="Reason 1"/>
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=//Incident/Reason2}" Header="Reason 2"/>
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=//Incident/Reason3}" Header="Reason 3"/>
                </GridView>
            </ListView.View>
        </ListView>

这在某种程度上起作用，但只带来并显示第一条记录，而不显示其余记录。我尝试了在这个网站上找到的其他东西（比如把XML放在项目目录中或者使用Grid Listview上的DataContext驻留），没有用。

我做错了什么或错过了什么？

非常感谢你们抱歉这些基本问题。＆lt;

Answer 2

如果你使用普通的Binding.Path应该绑定到DataContext对象的属性，该属性应该是XmlElement所以只需尝试{Binding Name}

Listview仅显示XML中的一条记录
