datgridview问题
我用splitcontainer把form隔开两部分，左边是datagridview控件只显示id和name，右边是很多的textbox,显示详细内容如性别，生日，电话等，如何编程实现选中左边一行，右边每个textbox的内容随之改变？

Public Class Form1

Dim conn As OleDbConnection
Dim da As OleDbDataAdapter
Dim ds As DataSet
Dim flag As Boolean

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
conn = New OleDbConnection( "Provider=Microsoft.Jet.OleDb.4.0;Data Source=D:/data.mdb ")
conn.Open()
da = New OleDbDataAdapter( "SELECT * FROM 表1 ", conn)
ds = New DataSet
da.Fill(ds)
conn.Close()
Me.DataGridView1.DataSource = ds.Tables(0)
flag = True
End Sub

Private Sub DataGridView1_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.SelectionChanged
If flag Then
Me.TextBox1.Text = Me.DataGridView1.Rows(Me.DataGridView1.SelectedCells(0).RowIndex).Cells(0).Value
Me.TextBox2.Text = Me.DataGridView1.Rows(Me.DataGridView1.SelectedCells(0).RowIndex).Cells(1).Value
End If
End Sub

End Class

在选中左边一行时触发事件，根据id到数据库中把数据检索出来，分别填充到右边的textbox中。
