Page Inheritance In Mixed .net Forms And MVC Application?
May 27, 2010
I'm working on a web application. One of my co-workers has written some asp.net forms pages. The page classes all inherit from BasePageClass, which of course inherits from the Page class. I wish to add some MVC controllers that I've been told need to use the same logic implemented in the BasePageClass. Ordinarily, I would want to inherit the functions in the BasePageClass in the controller classes, but this breaks the inheritance heirarchy.
We have a web site with pages written in both vb and c#. We wish to move from a web site to a web application. As a web application cannot mix languages, my thought was to build two separate applications within the same solution and have the main(c#) reference the secondary(vb) and (somehow) copy the vb pages into corresponding places in the c# directory structure at build time.
I have ASP.NET Page - PageBase and some pages that inherits this page:
public class PageBase : System.Web.Page public class SomePage : PageBase
I would like to have some controls placed in PageBase that every page that inherits from this page (like SomePage example) will have it displayed as well. This works perfectly in WinForms. If I place control (in designer mode) to WinForm A, I will get it displayed in form B - that inherits from A. This is perfect for building complex solution and I need to extend my WinForm solution to web.How will I do it in ASP.NET?
We got a problem that Sessions got mixed up when open multiple tab in a single application. We could change the code that do not use session variable in a that level, but a tons of page need to be modified. We need to find a quick fix for this problem. Is any thing we can do in code level to prevent user open multiple tab in a single application? O any thing we can do to keep its own session for a single tab?
I have a page that works great until now that they wanted to add a ModalPopup based on a field value. Before the addition of this modal popup, i had a button event that would do the inserting of the data, it caused the page to validate and as long as the page passed then it would insert and move on to the next page. Now i have a ModalPopup displaying IF a certain field is empty. If they answer Yes to the modalpopup question, it takes them back to the page and sets the focus on that field. Works fine, but if they select No then i need the page to validate and insert the record and move on.I have a customvalidator for the field i need to check. I then have my insert on the main button that causes the validation. The "Yes" and "No" buttons within the modalpopup have the following setup. [Code]....
My Main submit button has the following: [Code]....
If i select NO it just goes back to the page and doesnt move forward. If i select YES and enter something the page pops up the modal again and again because i've clicked in the field and keeps asking even though there is now a value in the field. But since there is a value, i can continue on to the next page.
I have a problem with Master Page InherItance. I make master page Item and past Index in the source of Master page Item and Design of Master Page is Ok but in Web page , in Source , I whrit ,
I have a base page called let's say Login.aspx with Login.aspx.cs code behind.Now...I would like to derive page from that page for several specyfic customers. Basically nothing changes in layout (aspx file), the only think is difference in handling Page_Load event. However when I access my derived login page LoginClientName.aspx no output is rendered - my aspx file contains only:
We have a webform this is in SSL but it is giving that mixed content message that everything on the page is not covered by SSL. Is this a simple matter of viewing source on the page and tracking down any links that may be pointing to an HTTP site rather than an HTTP site? And if I need these links how do I solve this problem?
Here is what I am trying to do. I have a page with two link buttons and an updatepanel (the two linkbuttons trigger the updatepanel). I have two usercontrols which have labels with same ID's. When I click the first link button, I add the first usercontrol to the updatepanel and set the label value to datetime.now
if i click the second link button i see that the value of the label from the first control is set in the label in second user control. if the id's are different there is no problem - but in my case the usercontrols are being developed by different teams and I am integrating them in the way i mentioned - so they may have same ids.
I have a website that deliveres content from secure source (https://) after the user authenticates. I added a new page where I use an Iframe to display a pdf file. It works fine when I try it from the dev server where I do not get directed from https, but when trying from the actual site I get the error message 'Do you want to view only the webpage content that was delivered securely?' I understand this is because the Iframe source is not secure (the source file is in the root directory of the webpage) Where should I store the content for the Iframe? Can I use a local directory on the server rather than one in the root directory?
My Development Server has: Windows 7 Home Premium 64 Bit IIS 7.5 ASP.Net 4.0
When I attempt to upload 1 file under 4mb, everything works wonderful When I attempt to upload 1, 2 or 3 files with a total size under 4mb, everything works wonderful When I attempt to upload 1 file, over 4mb or When I attempt to upload 1, 2, or 3 files that total over 4mb, a problem arises! And Continue to read and not assume it's just my Web.Config file, for I did attempt to set the maximum upload size to higher than 4mb, a copy of my Web.Config is included below!
Here is my Problem:
I have a need to upload 3 Files, 1 File being a .jpg file and the other 2 files will be .mp3 files. If I try to upload 1 file that is over 4mb or if the sum of the 3 files is over 4mb, I get a> The Regular Debug Message:

I have a question about mixed mode authentication. I've been doing some research into this, but I haven't found the answer yet, so I figured I'd just ask:
I have an internal application that requires login. Right now it's using forms-based authentication. We'd like to make it so that, if you're internal and authenticated against Active Directory, you don't need to login to the application. However, if you're coming in from the outside (or don't have an AD account), it would then require them to login via the forms-based Login.aspx page.
From my research, it seems that the only way to do this is to enable forms based auth as the default membership provider, then on the back-end do a check at Page_Load to pull their login name, match it against the .NET membership and then authenticate them automatically - am I wrong on this?
The documents I've found all seem to point to the user having to login anyway, just the login being stored in AD - instead of having the user just login once to their machine in the morning and using that to verify them and their roles in subsequent applications.
I have an ASP.NET application that can be installed with either Forms Authentication or Windows Authentication. All of my customers install using Windows Authentication. I use Forms Authentication in-house as it is easier for me to work with different clients. But enough about that.
I have a module as part of my application for Mobile Users. It displays a very simple HTML interface for low bandwith phones and air cards. It seems that some phones when going to this type of site that is Windows Authentication, it throws an error saying that you aren't authorized to view the page. From a computer, it will ask for credentials.
What I would like to do is use Windows Authentication Or Forms for my Main Application, but in the MOBILE folder, it would be nice if I could use FORMS Authentication. Can I mix the two? Can I just add a Web.Config to the folder for the Mobile Files and put FORMS Authentication?
The only other way I thought of doing this is:
1) create a seperate installable application that is always FORMS Authentication that is not part of the main application. Which sucks, as I now have to manage two applications.
2) In the main Web.Config I can set that folder to have no authentication and it will be avail to anyone, and then enforce my own authentication on the few pages it contains.
I am working on a very basic ASP.Net 2.0 website that will have a backend based on SQL Server 2005. The website has three basic pages (Home, About, and Contact) that are fully viewable by everyone. However, there is a fourth page called "Employee Login" that must present a Login/Password system to the visitor of the page. Upon successful login, a few more pages shall become accessible to authenticated users only.I need the simplest Form based authentication here however; the User Names and their Passwords are going to be coming from the SQL Database. Setting up the authentication to Form simply locks out the whole website. I need the basic pages to be login-free. Only certain pages need a login.
I have the requirement for internal users to acces our web app without loggin in manually so using windows authentication, external users need to be refered to a form based authentication.
Now I have implemented the solution [URL] ....
However I also need to employ roles for authorization. The forms side is all set up but I cannot seem to get it to work for the windows side of things, looking for implementing a mixed mode involving roles?
what is best to use in CTP 5 for inheritence. Ive heard of 3 ways of doing it. (This is indirectly addressed to Serenarules )
Table per Hierarchy ? Table per Type ? or able per Concrete Type ?
For those who wondering what the hell is that.. refer to http://weblogs.asp.net/manavi/default.aspx which is a nice blog about inheritence and polymorphism in CTP 5.
All my controllers inherit from a BaseController that has an ActionFilter attribute:
[AnalyticsData] public class BaseController : Controller {} public class AccountController : BaseController {} Some of my Actions in my controllers reuse the AnalyticsData ActionFilter: public class AccountController : BaseController { [AnalyticsData(Page="AccountProfile")] public ActionResult Profile() { // return View } }
I notice that the AnalyticsData ActionFilter only runs once. This is a good thing and I only want it to run once, but I'm wondering how that happens. If I set my breakpoint inside the OnActionExecuting:
public class AnalyticsAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { // break point set here } }
only gets hit once when AccountController serves it Profile view. How do ActionFilters and/or Attributes work that [AnalyticsData(Page="AccountProfile")] on the Action overrides/replaces [AnalyticsData] on BaseController?
I'm having a tough time implementing mixed-mode authentication (windows & forms based) for my application using IIS 7. Doing it in IIS6 is easy, but the process doesn't translate to 7/7.5 - and my research has led to me to conflicting answers, none of which.
I have redirect page called WindowsLogin.aspx, and a forms-based one called Login.aspx. I'm having difficulty enabling Windows authentication for just WindowsLogin.aspx.
I am trying to implement single sign on for users within our domain and if the are not then they get re-directed to the login screen to use forms authentication.
I have followed this tutorial below
however I get two issues firstly if I go to my forms authentication page no css or images now display and if i try to login i get an error.
If I go to the login page which should recognise me from the AD I get 401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.
