GridView中删除某行

--------------------编程问答-------------------- string sqlstr = "delete from [reg_stu] where [stu_id]=" + stu_id;

stu_id里面有值没有？ --------------------编程问答--------------------

protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e)

    {

        int stu_id = Convert.ToInt32(GridView2.DataKeys[e.RowIndex].Value.ToString());//你获取的行ID是GridView中的行索引，和数据库同步的？ 

  string sqlstr = "delete from [reg_stu] where [stu_id]=" + stu_id;



        SqlConnection con = new SqlConnection(sqlstr);

        con.Open();

        SqlCommand cmd = new SqlCommand(sqlstr,con);

        cmd.ExecuteNonQuery();

        cmd.Dispose();

        con.Close();

        GridView2.EditIndex =- 1;

        this.bind();

 

    }
