在不改变焦点的情况下将 datagridview 保存到 CSV

Question

我正在使用以下代码将我的 DataGridView table 保存到文本文件：

Dim rows = From row As DataGridViewRow In DataGridView1.Rows.Cast(Of DataGridViewRow)() _
                   Where Not row.IsNewRow _
                   Select Array.ConvertAll(row.Cells.Cast(Of DataGridViewCell).ToArray, Function(c) If(c.Value IsNot Nothing, c.Value.ToString, ""))
        Using sw As New IO.StreamWriter("Z:\SchData.txt")
            For Each r In rows
                sw.WriteLine(String.Join(";", r))
            Next
        End Using

并更新以下 table：

 While 1 = 1
            Try
                DataGridView1.Rows.Clear()
                Using stream As System.IO.FileStream = System.IO.File.OpenRead("Z:\SchData.txt")
                    Using reader As New System.IO.StreamReader(stream)

                        Dim line As String = reader.ReadLine()

                        While (line IsNot Nothing)
                            Dim columns = line.Split(";")
                            line = reader.ReadLine()
                            Dim index = Me.DataGridView1.Rows.Add()
                            Me.DataGridView1.Rows(index).SetValues(columns)
                        End While

                    End Using
                End Using
                Button107.Enabled = True
                Button88.Enabled = True
                updatingSch = False
                Return
            Catch ex As Exception
                Threading.Thread.Sleep(50)
            End Try
        End While

当我更改 table 中的值时，将调用这两个函数。问题是，它不是转到下一个单元格（当我切换、向下输入或单击另一个单元格时），而是将焦点短暂地设置到正确的单元格，但随后快速切换到左上角的单元格（第 0 行，第 1 列） 0).我怎样才能阻止它改变焦点？

这是编辑后保持在同一行的方法。

Private Sub dgv_CellEndEdit(sender As Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgv.CellEndEdit
  Dim index As Integer = dgv.FirstDisplayedScrollingRowIndex
    'do your file work then reset the row index 
  dgv.FirstDisplayedScrollingRowIndex = index
End Sub
