其实repeater的ItemCreated和ItemCommand事件也蛮好用的。

<asp:repeater id="rptsortimgUp" runat="server" OnItemCommand="rptsortimgUp_ItemCommand" OnItemCreated="rptsortimgUp_ItemCreated">
                                        <itemtemplate>
                                            <a href='<%# DataBinder.Eval(Container, "DataItem.f_url") %>' target="_blank"><img width="16" height="16" hspace="3"
                                align="absmiddle" src='/Images/FileIcons/icon_<%# DataBinder.Eval(Container, "DataItem.f_type") %>.gif' border="0"><%# DataBinder.Eval(Container, "DataItem.f_name") %></a><span style="font-size:11px">
                                                [<%# DataBinder.Eval(Container,    "DataItem.f_size", "{0:N0} Bytes") %>]</span>
                                            <asp:ImageButton ID="ibnsortimgUpDelete" ImageUrl="/Images/icon_delete.gif" Width="13" Height="13" ImageAlign="AbsMiddle" CommandName="Delete" CommandArgument='<%# DataBinder.Eval(Container, "DataItem.f_id") %>' causesvalidation="False" runat="server">
                                            </asp:ImageButton>
                                        </itemtemplate>
                                        <separatortemplate>
                                            |
                                        </separatortemplate>
                                    </asp:repeater>
