Question

WPF新手，我有一个带有gridview的列表视图。

我想将ID列绑定到文本框的text属性，但我似乎无法弄清楚如何访问所选项目的各个网格列

代码如下所示

<ListView HorizontalAlignment="Left" Name="listView1" VerticalAlignment="Top" 
          SelectionChanged="onSelectedIndexChange" DataContext="{Binding Source={StaticResource xmlDoc}, Path=xmdModule}" 
          ItemsSource="{Binding XPath=//*[@ID]}">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="ID"  Width="0" DisplayMemberBinding="{Binding Path=Attributes[ID].Value}" />
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Attributes[name].Value}" />
        </GridView>
    </ListView.View>
</ListView>
<TextBlock Grid.Column="1" HorizontalAlignment="Left" Name="textBlock1" Text="{Binding Path=SelectedValue}" 
           VerticalAlignment="Top" DataContext="{Binding ElementName=listView1}" TextWrapping="Wrap" 
           TextAlignment="Left" />

Answer 1

您可以尝试 将SelectedValuePath的{{1}}设置为ListView属性：

~~ID~~

OR 尝试将<ListView ..... SelectedValuePath="Attributes[ID].Value" .....>绑定到TextBox代替：

SelectedItem.Attributes[ID].Value

Answer 2

试试这个其中AttributeName是您要绑定的元素属性。

<GridViewColumn DisplayMemberBinding="{Binding XPath=@AttributeName}" Header="AttributeName" />

请参阅此链接以参考How to bind the xml element name to a ListView column in WPF XAML file

试过并且工作正常。
