DataGridView选择行错误

Question

我用一个文本框和一个DGV构建了一个自动提示搜索。一切都很好，除此之外，我确实想要两个按钮，可以向上或向下移动一排。你必须知道，当我搜索时，我将那些不包含搜索字符串的行设置为.visible = false。

理论上它应该是这样工作的：

Private Sub tsbDown_Click(sender As Object, e As EventArgs) Handles tsbDown.Click
    With dgvMA
       If dgvMA.RowCount > 0 Then
            Dim MyDesiredIndex As Integer = GetNextVisibleCell(dgvMA.CurrentRow.Index)
            dgvMA.ClearSelection()
            dgvMA.CurrentCell = dgvMA.Rows(MyDesiredIndex).Cells(1)
            dgvMA.Rows(MyDesiredIndex).Selected = True
        End If
    End With
End Sub
Private Function GetNextVisibleCell(currentrow As Integer) As Integer
    With dgvMA
        For i = currentrow To .Rows.Count - 1
            If .Rows(i).Visible = True Then
                MsgBox(i & ": " & .Rows(i).Visible)
                Return i
                Exit For
            End If
        Next
        Return currentrow
    End With
End Function

但我的行永远不会被选中。将multi-select设置为false并且将fullrowselect设置为true。当我手动点击一行或用键盘选中它时，所有内容都会正确打印。

我做错了什么？

这应该有效：

Private Sub tsbDown_Click(sender As Object, e As EventArgs) Handles tsbDown.Click
    With dgvMA
        If dgvMA.RowCount > 0 And dgvMA.CurrentRow.Index + 1 < dgvMA.Rows.Count Then
            Dim MyDesiredIndex As Integer = GetNextVisibleCell(dgvMA.CurrentRow.Index + 1)
            dgvMA.ClearSelection()
            dgvMA.CurrentCell = dgvMA.Rows(MyDesiredIndex).Cells(1)
            dgvMA.Rows(MyDesiredIndex).Selected = True
        End If
    End With
End Sub
Private Sub tsbUp_Click(sender As System.Object, e As System.EventArgs) Handles tsbUp.Click
    With dgvMA
        If dgvMA.RowCount > 0 And dgvMA.CurrentRow.Index <> 0 Then
            Dim MyDesiredIndex As Integer = GetNextVisibleCell(dgvMA.CurrentRow.Index - 1)
            dgvMA.ClearSelection()
            dgvMA.CurrentCell = dgvMA.Rows(MyDesiredIndex).Cells(1)
            dgvMA.Rows(MyDesiredIndex).Selected = True
        End If
    End With
End Sub
Private Function GetNextVisibleCell(currentrow As Integer) As Integer
    Dim i As Integer
    With dgvMA
        For i = currentrow To .Rows.Count - 1
            If .Rows(i).Visible = True Then
                ' MsgBox(i & ": " & .Rows(i).Visible)
                Return i
                Exit For
            End If
        Next
        Return currentrow
    End With
End Function

附言：我没有检查获得下一个可见单元格的代码，但它似乎可以，行选择工作正常
