vb2005 Datagridview 使用问题

form1的代码为：
Public Class Form1

    Private Sub StudyBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
        [color=#00FF00]Me.Validate()
        Me.StudyBindingSource.EndEdit()
        Me.StudyTableAdapter.Update(Me.StudyDataSet.study)

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: 这行代码将数据加载到表“StudyDataSet.study”中。您可以根据需要移动或移除它。
        Me.StudyTableAdapter.Fill(Me.StudyDataSet.study)
    End Sub

    Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
        Form2.show()
    End Sub
End Class[/color]
form1中的datagridview是直接拖动数据源上的表到窗体上实现的。
form2的代码为：
Imports System.Data.OleDb
Public Class form2
    Private connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\datagridview\datagridview\study.mdb"

    Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
        Dim SQLString As String = "INSERT INTO study VALUES('" + txtID.Text + "','" + txtName.Text + "',  '" + txtSex.Text _
                          + "', '" + txtAddress.Text + "' )"

        '调用编辑数据的模块
        Dim count As Integer = EditData.Insert(connStr, SQLString)
        If count > 0 Then
            MsgBox("添加数据成功！", MsgBoxStyle.OkOnly, "添加数据内容")
        End If
    End Sub
End Class

怎样才能实现当在form2中新增数据点击“确定”按钮后，form1中的datagridview中实现动态更新。看的眼睛好痛

补充：VB ,  控件
