受保护的覆盖Sub OnInit （e As System.EventArgs）
MyBase.OnInit（e）
Dim css As New HtmlLink
Dim stylesheet As String = ThemeWrapper.GetMyTheme.TenantStyleSheet
If String.IsNullOrEmpty（stylesheet）然后退出Sub
使用css
.Href = stylesheet
。属性（rel）=stylesheet
。属性（type）=text / css
以
结束MyBase.Header.Controls.Add（css）
End Sub
受保护的子Page_Load（ByVal sender As Object，ByVal e As System.EventArgs）处理Me.Load
如果不是Page.IsPostBack那么
Dim iNoticeboardId = Request.QueryString（ NoticeboardId）
LoadDocsGrid（iNoticeboardId）
结束如果
结束子
我尝试过：
i已经把
引用：< asp：PlaceHolder ID =PlaceHolder1runat =server>
，但我做了没有工作!!
