GridView自定義刪除操作的具體方法

首先，我們前端的代碼如下：

復制代碼 代碼如下:
<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="編輯" ControlStyle-Width="50" DataNavigateUrlFields="P_ID" DataNavigateUrlFormatString="smsModify.aspx?id={0}" Text="編輯"  >
                                <ControlStyle Width="50px"></ControlStyle></asp:HyperLinkField>
                                <asp:CommandField  ShowDeleteButton="true" DeleteText="刪除"   >
                                <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="名稱" 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="通知手機" SortExpression="P_tel" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_jg" HeaderText="通知間隔(小時)" SortExpression="P_jg" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_on" HeaderText="是否開啟" SortExpression="P_on" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_lasttime" HeaderText="最後發送時間" SortExpression="P_lasttime" ItemStyle-HorizontalAlign="Center"  >
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                                <asp:BoundField DataField="P_memo" HeaderText="備注" SortExpression="P_memo" ItemStyle-HorizontalAlign="Center"  >                  
                                <ItemStyle HorizontalAlign="Center"></ItemStyle></asp:BoundField>
                        </Columns>
                        <EmptyDataTemplate>
                        沒有數據！
                        </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>頁
                                /共<asp:Label ID="lblPageCount" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount %>'></asp:Label>頁  
                              <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page" Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首頁</asp:LinkButton>
                              <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一頁</asp:LinkButton>
                              <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一頁</asp:LinkButton>
                              <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"  Visible="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾頁</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>

後端的話，由於需要彈出刪除前的確認框，所以，我們需要在RowDataBound裡面做點什麼？同時，要想真正的刪除，還需要觸發RowDeleting事件，具體代碼如下：

復制代碼 代碼如下:
//報警刪除
        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("刪除成功！", this);
            else
                NXT_WLService.App_Code.JScript.Alert("刪除失敗！", 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("刪除"))//刪除鈕才加提示訊息 
                    btn.OnClientClick = "if (confirm('你確認要刪除?')) javascript:__doPostBack('gridViewDxjk','Delete$" + e.Row.RowIndex.ToString() + "'); else return false;";
            }
        }
