Answer 1

对于DataList，通常使用ItemCommand事件，请参考

.aspx

<asp:DataList ID="DataList1" runat="server"
onitemcommand="DataList1_ItemCommand">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Name") %>'></asp:Label>
<asp:Button ID="Button1" runat="server" CommandName="select" Text="选择"></asp:Button>
</ItemTemplate>
</asp:DataList>
<asp:Literal ID="lblMsg" runat="server"></asp:Literal>

.aspx.cs

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
{
BindData();
}
}

private void BindData()
{
List<User> list = new List<User>();
list.Add(new User { Id = 1, Name = "aa" });
list.Add(new User { Id = 2, Name = "bb" });
list.Add(new User { Id = 3, Name = "cc" });
list.Add(new User { Id = 4, Name = "dd" });
DataList1.DataSource = list;
DataList1.DataKeyField = "Id";
DataList1.DataBind();
}

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "select")
{
lblMsg.Text = (e.Item.FindControl("Label1") as Label).Text;
}
BindData();
}
}

public class User
{
public int Id { get; set; }
public string Name { get; set; }
}
