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：

//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;";
            }
        }
