Answer 1

你修改的是gridview绑定的数据源，更新这个数据源就好了。

1.UI

 protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        this.GridView1.PageIndex = e.RowIndex;
        int i = (int)this.GridView1.PageIndex;  
        BLL.userBLL UB = new userBLL();
        if (UB.deleteUserTBLL(i) > 0)
        {
            Response.Write("删除成功");
        }
        else {
            Response.Write("删除失败");
        }
    }

 

 

2.DAL

   public int deleteUserTDAL(string sql)
        {
            con.Open();
            SqlCommand cm = new SqlCommand(sql,con);
           
            return (int)cm.ExecuteNonQuery();
        }

 

3.BLL

       public int deleteUserTBLL(int ID)

        {
            string sql = "delete from user_tb  where userID='" +ID + "'  ";

            return (int)uDAL.deleteUserDAL(sql);

        }

删除不了信息，提示：删除失败

错来哪里呢
