我想先说一句,我才刚刚开始学习WPF。
我在我的学习项目中创建了一个小窗口,现在我试图找出最好的方法,将所选对象信息从ListView传递到按钮点击时发生的事件(在本例中,Remove)。
窗口看起来像这样:
Xaml是这样的:`
<Grid>
<Button Content="Add" HorizontalAlignment="Right" Margin="0,10,10,0" VerticalAlignment="Top" Width="50" Height="25" Click="Button_Click_Add"/>
<Button Content="Edit" HorizontalAlignment="Right" Margin="0,40,10,0" VerticalAlignment="Top" Width="50" Height="25" Click="Button_Click_Edit"/>
<Button Content="Remove" HorizontalAlignment="Right" Margin="0,100,10,0" VerticalAlignment="Top" Width="50" Height="25" Click="Button_Click_Remove"/>
<Button Content="Refresh" HorizontalAlignment="Right" Margin="0,70,10,0" VerticalAlignment="Top" Width="50" Height="25" Click="Button_Click_Refresh"/>
<ListView Name="lvEmployeeList" Margin="10,10,65,10">
<ListView.View>
<GridView>
<GridViewColumn Width="150" Header="First Name" DisplayMemberBinding="{Binding FirstName}" />
<GridViewColumn Width="150" Header="Last Name" DisplayMemberBinding="{Binding LastName}"/>
<GridViewColumn Width="150" Header="Position" DisplayMemberBinding="{Binding Position}"/>
</GridView>
</ListView.View>
</ListView>
</Grid>
字符串以及MainWindow类的相关信息:
public MainWindow()
{
InitializeComponent();
EmployeeList employeeList = EmployeeList.Load();
lvEmployeeList.ItemsSource = employeeList.employeeRecord;
}
private void Button_Click_Add(object sender, RoutedEventArgs e)
{
var newWindow = new UserInfo();
newWindow.Show();
}
private void Button_Click_Edit(object sender, RoutedEventArgs e)
{
MessageBox.Show("You have chosen to Edit");
}
private void Button_Click_Remove(object sender, RoutedEventArgs e)
{
MessageBox.Show("Removing");
}
private void Button_Click_Refresh(object sender, RoutedEventArgs e)
{
EmployeeList employeeList = EmployeeList.Load();
lvEmployeeList.ItemsSource = employeeList.employeeRecord;
MessageBox.Show("Attempting a Refresh");
}
}`
型
其中很多都是占位符函数,所以我最终可以真正处理数据。每个对象都有一个名字,姓氏,位置和后面的隐藏ID。我的计划是以某种方式获取对象ID并将其用于remove函数,但我不确定如何从ListView中的选定对象中获取该ID,然后仅在特定按钮单击事件中使用该ID。

我假设你有一个
Employee
类,如下所示:字符串
然后,您可以使用以下代码来获取
Employee
Id:型
