【请教】Access数据库insert一条数据之后，datagridview不能即时更新的问题
datagridview1在form1窗体中，form2窗体有对Access数据库进行改写的button1，我能够做到点击button1之后对数据库插入一条新的数据，可是form1中的datagridview1控件却没有即时对我插入的数据进行更新。我用的代码如下：
程序代码：OleDbConnection officer_connection = new OleDbConnection();
officer_connection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=officer.mdb";
Form1 myForm1 = new Form1();//实例化form1窗体
officer_connection.Open();
OleDbCommand upd_command = new OleDbCommand("select * from 员工信息",officer_connection);
OleDbDataAdapter officer_adapeter = new OleDbDataAdapter();
officer_adapeter.SelectCommand = upd_command;
DataSet mydataset = new DataSet();
officer_adapeter.Fill(mydataset,"员工信息");
myForm1.dataGridView1.DataSource = mydataset.Tables["员工信息"] ;
officer_connection.Close();
upd_command.Dispose();还请高手指点如何修改或者如何做？
