我在dataGridView中删除了一条信息｀｀，但是dataGridView还是有显示
　　我想刷新下dataGridView控件或是关闭这个子窗体然后重新加载进来｀｀
我在网上找了好久，就是没有找到相关的解决办法｀｀求路过的朋友开开金口｀
就这个问题搞了我一下午了｀｀｀

  在线等```````

用databinding试试

try
                {
                    oleConn.Open();
                    string sql = "delete * from StudentInfo where StudentNumber='"+full.id+"'";
                    OleDbCommand cmd = new OleDbCommand(sql, oleConn);
                    cmd.ExecuteNonQuery();
                    MessageBox.Show("数据删除成功");

                    Fm_学员删除 Child = new Fm_学员删除();
                    Child.FormClosed += new FormClosedEventHandler(Child_FormClosed);
                    Child.Show();
                    
                    
                }
                catch (Exception ex)
                {
                    MessageBox.Show("您的错误信息是："+ex.Message);
                }
                finally
                {
                    oleConn.Close();
                }
        }
        void Child_FormClosed(object sender, FormClosedEventArgs e)
        {
            this.Close();
        }

具体怎么加｀｀｀我刚学这个｀｀

你删完之后再执行一下dataBinding()

在更新要先清空DataGridView
