主题：求助 选定动态控件的当前行,控件颜色加深

  If Typeof e.Sender Is WinForm.TextBox Then
        For Each c As object In e.Form.Children
            If Typeof c Is WinForm.TextBox Then c.BackColor = SystemColors.Control
        Next
        If e.Sender.BackColor = Color.FromARGB(72, 71, 73) Then
            e.Sender.BackColor = Color.FromARGB(42, 41, 43)
        Else
            e.Sender.BackColor = Color.FromARGB(72, 71, 73)
        End If       
    End If

            如果我选中第一个,变了颜色, 选了第二个,第二个变颜色的同时第一个灰复原来的颜色,怎样写代码?

请老师指教!
