Dec 17, 2010

Is there a way to pass a reference of a page to a helper class? Scenario: [ASP.NET 2.0 Web Application] The page is a content page which has a MasterPage. The page calls a method in the helper class and passes the page byRef as an argument. The method in the helper class tries to find a control on the passed in page and set values. Problem: Only the MasterPage is being exposed and not the page I am trying to pass. Any recommendations on passing the page so that I can set the values of the controls within it?

Using Ajax Script To Load Content From An Aspx Page On Another Server Than The Page Calling The Content

Mar 22, 2010

I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.

I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.

Content Controls Allowed Only In Content Page That References A Master Page

Mar 10, 2016

Can I ask what this error refers to, (I have had it twice now over the last couple of days and then it goes away):

System.Web.HttpException: Content controls are allowed only in content page that references a master page.

This is followed by Stack Trace:

[HttpException (0x80004005): Content controls are allowed only in content page that references a master page.]
System.Web.UI.MasterPage.CreateMaster(TemplateControl owner, HttpContext context, VirtualPath masterPageFile, IDictionary contentTemplateCollection) +9744256
System.Web.UI.Page.get_Master() +55
System.Web.UI.Page.ApplyMasterPage() +14
System.Web.UI.Page.PerformPreInit() +51
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1104

I am not using any Content Place Holder or Master Page (does the error refer to the Site.Master file because while I can see it in. Solution Explorer, I never use it. All of my aspx files look like this along the top with no reference to Site.Master:

Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="register1.aspx.vb" Inherits="register1" %>

HttpHandler Cannot Find Content Control?

Feb 23, 2011

I have an aspx page that I cannot touch. It's a shared page. However, I want to override the navigation control that the page provides and instead use the default content on my masterpage. So, I'm being asked to create an HTTP handler. This handler will intercept requests for the page and remove the control that is overriding the default content. One problem is that the Content control has no ID. I've hooked into the page's PreInit event and am attempting to traverse the control heirarchy using a recursive method that will find the control using the ContentPlaceHolderID property. However, when I go to access the page's Controls property, it shows a single control, which is my master page. I cannot seem to access any other controls on my .aspx page. Would anyone know how to be able to find the Content control?

AJAX :: Can Change The Content Of The Content Place Holder To A New Page With Asynchronous Postback

Jan 4, 2010

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.
