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!!

解决方案

（< div class ='full-popup'>< div class ='file-popup'>< a href ='＃'onclick ='javascript：closeHandler（）;'class ='close-full-popup'> 关闭< / a>< div class ='iframe-holder'style ='overflow：auto; -webkit-overflow-scrolling：touch;'>< iframe scrolling ='yes'>< / iframe>< / div>< / div>< / div>）。appendTo（body ）; var src =../User/ShowDocument.aspx?DocumentID=+ docId;

（。full-popup iframe）。 attr（src，src +＃view = fit）;

（document）.on（click，。close-full-popup，function（）{

What I have tried: i have put

Quote:

<asp:PlaceHolder ID="PlaceHolder1" runat="server">

in body but i did not worked !!

解决方案

("<div class='full-popup'><div class='file-popup'><a href='#' onclick='javascript:closeHandler();' class='close-full-popup'> Close</a><div class='iframe-holder' style='overflow:auto; -webkit-overflow-scrolling:touch;'><iframe scrolling='yes'></iframe></div></div></div>").appendTo("body"); var src = "../User/ShowDocument.aspx?DocumentID=" + docId;

(".full-popup iframe").attr("src", src + "#view=fit");

(document).on("click", ".close-full-popup", function () {
