单击按钮时获取 object/item（动态创建的按钮）- 堆栈面板

Question

我正在循环我的客户，我需要为每个客户创建一个按钮以防万一我想删除那个特定的客户。

所以这是我的代码：

foreach (var item in customersList)
{
    Button btn = new Button();
    btn.Content = "Customer": + " " + item.Value;
    btn.Height = 40;
    btn.Click += btn_Click;

    TextBox cust = new TextBox();
    cust.Height = 40;
    cust.Text = item.Value;

    stackCustomers.Children.Add(cust);
    stackCustomers.Children.Add(btn);
}

我如何附加事件单击我的按钮，以便在单击它时获得客户？

void btn_Click(object sender, RoutedEventArgs e)
{     
    //I tried this but it is not working, unfortunatelly...
    Customer cust = (Customer)sender;
}

Answer 1

简单的方法：将客户附加到 Button.Tag 属性

Button btn = new Button();
btn.Tag = item; // .Value maybe?

// ...

void btn_Click(object sender, RoutedEventArgs e)
{
    var button = sender as Button;
    Customer cust = (Customer)button.Tag;
}

可能更好的方法：创建包含按钮的每个客户项目的可视化表示。使用 Button.Command 和 Button.CommandParameter={Binding PathToCustomer} 而不是 Button.Click.
