<body>
    <form id="form1" runat="server">
        <asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" OnItemDataBound="DataList1_ItemDataBound">
            <ItemTemplate>
                <asp:Button ID="Button1" runat="server" Text="Button" />
                <asp:Label ID="Label1" runat="server" Text='<%# Eval("ProductName") %>'></asp:Label>
            </ItemTemplate>
        </asp:DataList>
                <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=.\SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True" ProviderName="System.Data.SqlClient" SelectCommand="select * from products"></asp:SqlDataSource>
    </form>
</body>
</html>

------解决方案--------------------
使用DataList的ItemDataBound事件循环的为每一个Button添加事件

C# code

    protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        (e.Item.FindControl("Button1") as Button).Attributes.Add("onclick", "show('" + 当前的行的Label-- > id + "')");
    }
