ASP.NET从ListView获取Selected List项数据 [英] ASP.NET Get the Selected List item data from ListView

问题描述

我有一个ASP.NET Listview，它由Datatable填充。

I have ASP.NET Listview which is populated by a Datatable.

<asp:ListView ID="lvCustomers" runat="server" GroupPlaceholderID="groupPlaceHolder1"
                                                    ItemPlaceholderID="itemPlaceHolder1" OnPagePropertiesChanging="lvCustomers_PagePropertiesChanging" ClientIDMode="AutoID">

在页面的正文中，我打印出表中的值：

In the page's body I have printed out the values from the table:

<asp:Label ID="idlbl" runat="server" Visible="false" Text='<%# Eval("id") %>'></asp:Label>
<h4 class="timeline-title"><%# Eval("ActivityContent") %></h4>

在后面的代码中，我需要通过按钮单击事件将标签'idlbl'的值作为String获取。我该怎么做？

In the code behind, I need to get the value of label 'idlbl' as a String through a button click event. How do I do this?

如果Button在ListView之外，那么你需要遍历ListView的项目并在循环中获取。



如果Button在里面，那么你可以使用 ListView.ItemCommand事件 [ ^ ]并找到当前项目及其属性。

If the Button is outside of ListView, then you need to loop through the Items of ListView and fetch inside the loop.

If the Button is inside, then you can use ListView.ItemCommand Event[^] and find the current item and its properties.
