从datagridview中的选定行滚动

Question

我创建了一个代码，其中在datagridviw中搜索项目，当用户点击enter或down键时焦点设置为datagridview，我想要从所选行开始滚动staart但是它从最后选择的行开始。

我的代码：

  Private Function FindItems(ByVal strSearchString As String) As Boolean
    dgvsearchitem.ClearSelection()
 For Each myRow As DataGridViewRow In dgvsearchitem.Rows
        For Each myCell As DataGridViewCell In myRow.Cells
            If InStr(myCell.Value.ToString, strSearchString,CompareMethod.Text) Then
                myRow.Selected = True
                Return True
            End If
        Next
    Next
    Return False

End Function
 Private Sub txtitemsearch_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtitemsearch.KeyDown
    If (e.KeyCode = Keys.Enter Or e.KeyCode = Keys.Down Or e.KeyCode = Keys.Tab) And txtiname.Text <> "" Then
        dgvsearchitem.Focus()

    End If

End Sub
