Question

我将项目添加到了ListView中，并且这些元素都在其中。我知道这是因为我只能单击ListView的前两行，并且添加了2个Elements。

<ListView x:Name="userListview"  HorizontalAlignment="Left" Height="220" Margin="40,40,0,0" VerticalAlignment="Top" Width="200">
                <ListView.View>
                    <GridView AllowsColumnReorder="True" ColumnHeaderToolTip="User Informationen">
                        <GridViewColumn Header="User" Width="50" DisplayMemberBinding="{Binding Name}"/>
                        <GridViewColumn Header="Email" Width="150" DisplayMemberBinding="{Binding Name}"/>
                    </GridView>
                </ListView.View>
            </ListView>

和我的VB.Net代码：

users = New ObservableCollection(Of UserInformation)()

        For i = 0 To globalUserList.Count - 1
            users.Add(New UserInformation() With {
                      .Username = globalUserList(i).ToString,
                      .Email = globalUserList(i + 1).ToString})
            i = i + 1
        Next

        userListview.ItemsSource = users

预期结果应是这些项目可见且可读。

Answer 1

您正在绑定属性Name，该属性似乎不存在。

看起来应该是：

<GridViewColumn Header="User" Width="50" DisplayMemberBinding="{Binding Username}"/>
<GridViewColumn Header="Email" Width="150" DisplayMemberBinding="{Binding Email}"/>

Answer 2

它应该看起来像这样。名称有误

<ListView x:Name="userListview" HorizontalAlignment="Left" Height="220" Margin="40,40,0,0" VerticalAlignment="Top" Width="200">
    <ListView.View>
        <GridView AllowsColumnReorder="True" ColumnHeaderToolTip="User Informationen">
            <GridViewColumn Header="User" Width="50" DisplayMemberBinding="{Binding Username}"/>
            <GridViewColumn Header="Email" Width="150" DisplayMemberBinding="{Binding Email}"/>
        </GridView>
    </ListView.View>
</ListView>

ListView不显示我来自Itemsource的项目
