相关疑难解决方法(0)

我是Binding和WPF的新手我最近学会了如何listBox使用Binding技术创建多列

 <ListView ItemsSource="{Binding Items}" Margin="306,70,22,17" MouseDoubleClick="listBoxSS_MouseDoubleClick" Name="listBoxSS" >           
    <ListView.View>
            <GridView>
                <GridView.Columns>
                    <GridViewColumn Header="first_name " Width="100" DisplayMemberBinding="{Binding Path=First_name}" />
                    <GridViewColumn Header="last_name" Width="100" DisplayMemberBinding="{Binding Path=Last_name}" />
                    <GridViewColumn Header="phone_number" Width="100" DisplayMemberBinding="{Binding Path=Phones[0]}" />
                    <GridViewColumn Header="notes" Width="100" DisplayMemberBinding="{Binding Path=Notes}" />
                </GridView.Columns>
            </GridView>
        </ListView.View>
    </ListView>

这是代码:

List<Student> arr = search.students();
        listBoxSS.ItemsSource = arr;

但问题是当我尝试使用添加或删除项目或清除时

 listBoxSS.Items.Clear();

我需要一个使用项目源的示例或我可以添加或删除项目或清除列表的方式.

编辑:

<ListView ItemsSource="{Binding Items}" Margin="306,70,22,17" MouseDoubleClick="listBoxSS_MouseDoubleClick" Name="listBoxSS" >
    <ListView.View>
        <GridView>
            <GridView.Columns>
                <GridViewColumn Header="first_name " Width="100" DisplayMemberBinding="{Binding Path=First_name}" />
                <GridViewColumn Header="last_name" Width="100" DisplayMemberBinding="{Binding Path=Last_name}" />
                <GridViewColumn Header="phone_number" Width="100" …
