於form2加form1中datagridview中的的！
我的用意是form2加载form1中datagridview中的数据，利用form2修改数据源中的数据，贴上代码，老手帮我看看，
为什么form2总是显示datagridview中的第一行数据，我要的是显示当前点击的行的数据，谢谢了。。

VB.NET code

Imports System.DataImports System.Data.SqlClientPublic Class JBZL    Inherits System.Windows.Forms.Form    Friend objconnection As SqlConnection = New SqlConnection("server=DADI-20111226ZE;database=plan;user id=sa;password=123")    Public objdataAdapter As New SqlDataAdapter    Public objdataset As New DataSet()    Private Sub JBZL_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load        objdataAdapter.SelectCommand = New SqlCommand        objdataAdapter.SelectCommand.Connection = objconnection        objdataAdapter.SelectCommand.CommandText = "SELECT * FROM bom"        objdataAdapter.SelectCommand.CommandType = CommandType.Text        objconnection.Open()        objdataAdapter.Fill(objdataset, "bom")        objconnection.Close()        DataGridView2.DataSource = objdataset        DataGridView2.DataMember = "bom"        objdataAdapter = Nothing        objconnection = Nothing    End Sub    Private Sub DataGridView2_RowHeaderMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView2.RowHeaderMouseDoubleClick        If Me.DataGridView2.SelectedRows.Count > 0 Then            JBZL_BOM.ShowDialog()        End If    End Sub    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click          End SubEnd Class

[解决办法]
你在form1里面已经连接数据库了 在form2里面只需要DataGridView2.DataSource = form1.objdataset
然后再帮定你的控件就可以了
