Question

This is a bit different to all the other questions as they all seem to refer to the head content specifically. With this one, I have a user control with the following placeholder:

<asp:PlaceHolder runat="server" ID="DiscussIncludes">    
    <script>
        var OnLastPage = <asp:Literal runat="server" ID="OnLastPageJS" />;
        var AJAXWait = false;
        var MinChars = <%=Settings.MinimumCommentChars%>;
        var AJAXURL = "<%=ResolveClientUrl("~/Handlers/DiscussAjaxHandler.ashx")%>";
        var CurrUsername = "<%=ThisUser.Username %>";
        var GravHash = "<asp:Literal runat="server" ID="GravJSRef" />";
        var RelURL = "<%=ResolveClientUrl("~/users/")%>";
        var Anch = "<%=Anchor.ToString()%>";
        var MyRep = "<%=MyRepString%>";
        var CurrReportID = 0;
        var LastPageURL = "<asp:Literal runat="server" ID="JSLastPageURL" />";
        var AllowedChars = <%=Settings.MaxCommentChars %>;
    </script>
    <script src="<%=CommonFunctions.AllocateStaticPath("/js/Discuss.js?v=" + Settings.JSVersionID)%>"></script>
    <script src="<%=CommonFunctions.AllocateStaticPath("/js/BlockUI.js?v=" + Settings.JSVersionID)%>"></script> 
</asp:PlaceHolder>

在我后面的法典中:

ContentPlaceHolder FooterControl = (ContentPlaceHolder)Page.Master.FindControl("JavascriptIncludes");
FooterControl.Controls.Add(DiscussIncludes);

这一错误:

不能修改控制收集,因为控制含有密码区块(即:%......>);

。 Add(DiscussIncludes);。 I ve Trial changing all the <%= to <%# within the place holder but no luck.

值得注意的是,这一控制在我的所有其他网页上都做了罚款。造成这种情况的想法是什么?

Answer 1

这种控制没有造成问题——如果在你把控制权附加给特定环境时发生,而且只在这种环境中出现问题。申诉网页上还有什么?

Answer 2

我在我的系统上尝试了以下工作,似乎在发挥作用。

<asp:PlaceHolder runat="server" ID="DiscussIncludes">    
    <script type="text/javascript">
        var path = <%=Common.path%>;
    </script>
    <script type="text/javascript" src= <%=Common.GetScriptPath("jquery-1.4.1-vsdoc.js")%> ></script>
    <asp:PlaceHolder runat="server" ID="JsIncludes"> 
    </asp:PlaceHolder>
</asp:PlaceHolder>

准则。

    LiteralControl include = new LiteralControl(string.Format("<script src= {0} ></script>", Common.GetScriptPath("jquery-1.4.1.min.js")));
JsIncludes.Controls.Add(include);

I get the exception if i try to add the control to DiscussIncludes. However if add the control to JsIncludes it works. JsIncludes control is a child placeholder of DiscussIncludes.
