上面那个图里面已经有了dgv1.rows.count 共3395行

这个dgv1所在的窗体是form2
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Form2.MdiParent = Me
        Form2.Dock = DockStyle.Fill
        Form2.Show()
        Form3.MdiParent = Me
        Form3.Show()
End Sub
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim s1 As String
        dgv1.Rows.Add(Form1.dgv1.RowCount - 6)
        For i As Integer = 0 To Form1.dgv1.Rows.Count - 7
            s1 = CStr(Form1.dgv1(0, i).Value)
            dgv1(0, i).Value = s1
        Next
        dgv1.FirstDisplayedScrollingRowIndex = dgv1.RowCount - 1'''''''''这里就出问题了
    End Sub

首先,抱歉我上面的说明有误,dgv1在form2里面而不是在form3里面,已经改了.

dgv1在form2的TableLayoutPanel1里面 TableLayoutPanel1的dock也是fill
我发现要么把Form2.Dock = DockStyle.Fill去掉 要么把TableLayoutPanel1的dock改成none
两种方法都没有出现这个错误 但这两个我都需要是fill
