GridView自定义删除操作的具体方法

首先，我们前端的代码如下：

复制代码 代码如下:

<asp:GridView CssClass="gridview" runat="server" AllowPaging="True"
                  DataKeyNames="P_ID" AutoGenerateColumns="False" 
                      RowStyle-HorizontalAlign="Center" BorderWidth="1px" PageSize="17"
                      onrowdeleting="gridViewDxjk_RowDeleting"
                      OnRowDataBound="gridViewDxjk_RowDataBound"
                      onpageindexchanging="gridViewDxjk_PageIndexChanging" >
                        <HeaderStyle CssClass="head" />
                        <PagerStyle CssClass="pager" />
                        <RowStyle CssClass="row" />
                        <EditRowStyle CssClass="editrow" />
                        <AlternatingRowStyle CssClass="altrow" />
                        <EmptyDataRowStyle CssClass="empty" />
                        <Columns>                           
                         <asp:HyperLinkField HeaderText="编辑" ControlStyle-Width="50" DataNavigateUrlFields="P_ID" DataNavigateUrlFormatString="smsModify.aspx?id={0}" Text="编辑"  >
                                <ControlStyle></ControlStyle></asp:HyperLinkField>
                                <asp:CommandField  ShowDeleteButton="true" DeleteText="删除"   >
                                <ControlStyle></ControlStyle></asp:CommandField>
                                <asp:BoundField DataField="P_ID" HeaderText="id" SortExpression="P_ID" ItemStyle-HorizontalAlign="Center"  Visible="False" >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_NAME" HeaderText="名称" SortExpression="P_NAME" />
                                <asp:BoundField DataField="P_Type" HeaderText="通知方式" SortExpression="P_Type" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_Fzr" HeaderText="姓名" SortExpression="P_Fzr" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_tel" HeaderText="通知手机" SortExpression="P_tel" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_jg" HeaderText="通知间隔(小时)" SortExpression="P_jg" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_on" HeaderText="是否开启" SortExpression="P_on" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_lasttime" HeaderText="最后发送时间" SortExpression="P_lasttime" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_memo" HeaderText="备注" SortExpression="P_memo" ItemStyle-HorizontalAlign="Center"  >                  
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                        </Columns>
                        <EmptyDataTemplate>
                        没有数据！
                        </EmptyDataTemplate>
                         <PagerTemplate>
                        <table>
                            <tr>
                            <td>
                                第<asp:Label runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>'></asp:Label>页
                                /共<asp:Label runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount %>'></asp:Label>页&nbsp;&nbsp;
                              <asp:LinkButton runat="server" CommandArgument="First" CommandName="Page" Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton>
                              <asp:LinkButton runat="server" CommandArgument="Prev" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>
                              <asp:LinkButton runat="server" CommandArgument="Next" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>
                              <asp:LinkButton runat="server" CommandArgument="Last" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>
                              <asp:TextBox runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>'  AutoPostBack="true" ></asp:TextBox>
                              <asp:LinkButton runat="server" CommandArgument="GO" CommandName="Page" Text="GO"></asp:LinkButton>
                            </td>
                            </tr>
                        </table>
                    </PagerTemplate>
                 </asp:GridView>

后端的话，由于需要弹出删除前的确认框，所以，我们需要在RowDataBound里面做点什么？同时，要想真正的删除，还需要触发RowDeleting事件，具体代码如下：

复制代码 代码如下:
