How to display List items in Listview?
提问by Bramble
I have a ListView in my aspx file like this:
我的 aspx 文件中有一个 ListView，如下所示：
<asp:ListView ID="ListView1" runat="server"></asp:ListView>
and then I have List like this:
然后我有这样的列表：
List<string> mylist = new List<string>();
Im trying to populate the ListView like so:
我试图像这样填充 ListView：
foreach(string elem in mylist)
{
ListView1.Items.Add(new ListViewItem(elem));
}
But my compiler is telling me best overload match error & cannot convert string to ListViewItem. This is a asp.net 4.0 web app. Any suggestions?
但是我的编译器告诉我最好的重载匹配错误并且无法将字符串转换为 ListViewItem。这是一个 ASP.NET 4.0 网络应用程序。有什么建议？

Try binding your ListView like the following:
尝试像下面这样绑定你的 ListView：
code-behind
代码隐藏
List<string> mylist = new List<string>() { "stealthy", "ninja", "panda"};
listView.DataSource = mylist;
listView.DataBind();
aspx
aspx
<asp:ListView ID="listView" runat="server">
<ItemTemplate>
<asp:Label Text="<%#Container.DataItem %>" runat="server" />
</ItemTemplate>
</asp:ListView>

With a ListView, you should be able to bind the data to the DataSourceof the control:
使用ListView，您应该能够将数据绑定到DataSource控件的 ：
ListView1.DataSource = myList;
ListView1.DataBind();
回答by John Weldon
ListViewItemdoes not have any constructor that takes a string.
Also ListView.Itemsis an IList<ListViewDataItem>not a collection of ListViewItem
ListViewItem没有任何接受字符串的构造函数。此外ListView.Items是IList<ListViewDataItem>不是一个集合ListViewItem
You probably want to use databinding rather than iteratively adding items anyway.
您可能想要使用数据绑定而不是迭代添加项目。
