gridview自定义删除操作的实现代码

发布时间:2020-03-23编辑:脚本学堂
本文介绍下,在asp.net中gridview实现添加一行删除列,删除前弹出通知提示的实现代码,供大家学习参考。

在GridView中新添加一行“删除”列,删除前弹出提示等,具体实现代码如下。

1,前端代码:
 

复制代码 代码示例:
<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>

2,后端代码
需要弹出删除前的确认框,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。
 

复制代码 代码示例:
//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;";
 }
}
