这篇CFSDN的博客文章GridView自定义删除操作的具体方法由作者收集整理,如果你对这篇文章有兴趣,记得点赞哟.

首先,我们前端的代码如下:

  。

复制代码代码如下:

<asp: GridView ID="gridViewDxjk" 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 Width="50px"></ControlStyle></asp:HyperLinkField>
                                <asp:CommandField  ShowDeleteButton="true" DeleteText=" 删除"   >
                                <ControlStyle Width="50px"></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 width="100%" class="gvPage" style="font-size:12px;">
                            <tr>
                            <td style="text-align: right">
                                第<asp:Label ID="lblPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>'></asp:Label>页
                                /共<asp:Label ID="lblPageCount" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount %>'></asp:Label>页  
                              <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page" Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton>
                              <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>
                              <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>
                              <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>
                              <asp:TextBox ID="txtNewPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>'  Width="20px" AutoPostBack="true" ></asp:TextBox>
                              <asp:LinkButton ID="btnGoEx" runat="server" CommandArgument="GO" CommandName="Page" Text="GO" OnClick="btnGoEx_Click"></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:

//报警删除         protected void gridViewDxjk_RowDeleting(object sender, GridViewDeleteEventArgs e)         {             string key = gridViewDxjk.DataKeys[e.RowIndex].Value.ToString();             bool flag = bll.Delete(Int32.Parse(key));             if (flag)                 NXT_WLService.App_Code.JScript.Alert("删除成功!", this);             else                 NXT_WLService.App_Code.JScript.Alert("删除失败!", this);         } 。

  。

                 protected void gridViewDxjk_RowDataBound(object sender, GridViewRowEventArgs e)         {             if (e.Row.RowType == DataControlRowType.DataRow)             {                 LinkButton btn = (LinkButton)e.Row.Cells[1].Controls[0];                 if (btn.Text.Equals("删除"))//刪除鈕才加提示訊息                       btn.OnClientClick = "if (confirm('你确认要删除?')) javascript:__doPostBack('gridViewDxjk','Delete$" + e.Row.RowIndex.ToString() + "'); else return false;";             }         } 。

  。
