Repter行处理 CommandName 和 CommandArgument的用法

<table>
        <tr><td>姓名</td><td>操作</td></tr>
        <asp:Repeater ID="Repeater1" runat="server" DataSourceID="ObjectDataSource1" 
            onitemcommand="Repeater1_ItemCommand"

            <ItemTemplate>
                <tr id="trMem" runat="server"><td><%#Eval("Name") %></td>
                <td><asp:Button OnClientClick='return confirm("确认要启用吗？")' Text="启用" CommandName="Enabled" CommandArgument='<%#Eval("Id") %>' ID="btnEnabled" runat="server" />
