主题：[求助]单选按钮。

对于单选按钮，点击了通过，出现提示框，然后选择取消，为什么通过的单选按钮仍然处于选中状态？请看红色的代码？取消选中不应该是e.Sender.Checked = False？

If e.Sender.Checked Then
    Dim r As Row = Tables("需求明细表").Current
    If r IsNot Nothing Then
        If MessageBox.show("确认现场测试通过?","博达软件管理系统",MessageBoxButtons.OKCancel,MessageBoxIcon.Question)=DialogResult.OK Then
            DataTables("临时版本跟踪表").ReplaceFor("状态", "Confirmed", "需求编号 = '" & r("需求编号") & "'")
            DataTables("临时版本跟踪表").ReplaceFor("已确认可以发布", "True", "需求编号 = '" & r("需求编号") & "'")
            Dim m As New MailSender
            m.Host = "mail.bdcom.com.cn"
            m.Account = "version@bdcom.com.cn"
            m.Password = "version"
            m.From = "version@bdcom.com.cn"
            If r.IsNull("邮件通知") = False Then
                m.AddReceiver(r("邮件通知").Replace(vbcrlf, ",").Replace(chr(13), ",").Replace(chr(10), ","))
            End If
            If r.IsNull("研发邮箱") = False Then
                m.AddReceiver(r("研发邮箱").Replace(vbcrlf, ",").Replace(chr(13), ",").Replace(chr(10), ","))
            End If
            If r.IsNull("技术支持邮箱") = False Then
                m.AddReceiver(r("技术支持邮箱").Replace(vbcrlf, ",").Replace(chr(13), ",").Replace(chr(10), ","))
            End If
            If r.IsNull("退回通知") = False Then
                m.AddReceiver(r("退回通知").Replace(vbcrlf, ",").Replace(chr(13), ",").Replace(chr(10), ","))
            End If
            m.Title = "博达软件管理系统= = = = = = =" & "需求编号:" & r("需求编号") &"<= = =>临时版本编号:" & r("临时版本编号") & "======" & "现场确认已通过,请发布版本"
            m.C & r("需求编号") &"<= = =>临时版本编号:" & r("临时版本编号") & "======" & "现场确认已通过,请发布版本"  & vbcrlf & "现场已确认好的版本路径:" & "192.168.1.35\bdcom"  & r("发布目录").Replace("[", "").Replace("]", "").Replace("/", "\")
            m.Send
            MessageBox.show("需求编号:" & r("需求编号") &"<= = =>临时版本编号:" & r("临时版本编号")  & "此版本现场确认通过,测试部将发布!","博达软件管理系统")
            r("状态") = "Confirmed"
        End If
        Else
        e.Sender.Checked = False
    End If
End If
