同一个winform窗体上2个DataGridView数据绑定问题

[已解决问题] 解决于 2016-04-22 16:01

我在同一个winform窗体上放了2个DataGridView，窗体加载时想给这两个DataGridView都绑定上数据并显示，现在却始终只能显示一个，实际上都取到数据了，不知道问题出在哪儿，求助

代码如下：

 private void frmMain_Load(object sender, EventArgs e)
        {

            LoaddgvSignUpInfo();//载入1
            LoaddgvEnterSchoolInfo();//载入2
        }
        
          private void LoaddgvSignUpInfo()
        {
            string sql = "select top 50 Id,StudentName from StudentSignUpInfo";
            SqlDataReader reader = SqlHelper.ExecuteReader(sql);

            if (reader.HasRows)
            {
                BindingSource bs = new BindingSource();
                while (reader.Read())
                {
                    bs.DataSource = reader;
                    dgvSignUpInfo.DataSource = bs;//绑定datagridview1的数据
                }
            }
        }
        
         private void LoaddgvEnterSchoolInfo()
        {
            string sql2 = "select top 50 Id,StudentName from StudentEnterSchoolInfo";
            SqlDataReader reader2 = SqlHelper.ExecuteReader(sql2);

            if (reader2.HasRows)
            {
                BindingSource bs2 = new BindingSource();
                while (reader2.Read())
                {
                    bs2.DataSource = reader2;
                    this.dgvEnterSchoolInfo.DataSource = bs2;//绑定datagridview2上的数据
                }
            }
        }
