C# - How To Persist Authentication From One Web App To Another
Feb 18, 2011
So my company has an ASP.NET web app, targeting .NET 3.5. I am tasked with building a ticketing system for them. I don't really need to use any resources of the company app, except for authentication. I would like to target .NET 4.0 and use the 4.0 goodies like entity framework and mvc 3.0. If I create an application targeting .net 4 nested within the main web app in IIS, is there a way to persist authentication so they do not require a different session within the 4.0 web app?
Just going to start making a web application and was wondering which was better, or at least what are the main differences between them (as it probably matters what I am using them for)?
I am using business objects that are accessed via webservices. These objects can be loaded via the webservice and serialized to my mvc app. The mvc app can get a web reference to the objects and they can be utilized in the mvc app. However, the business objects are where the classes are defined, and where the annotations are applied.
The mvc validation seems to have no idea that there are System.ComponentModel.DataAnnotations attributes applied to this business object class.
1) Are DataAnnotations lost when objects are serialized / deserialized?
2) If in mvc I use a view model approach, and have nested objects (which themselves have public properties - decorated with DataAnnotations) can/will the mvc validation system traverse the entire object model, the model being used for my view? (so it can see DataAnnotations attributes of the nested object)?
I have an application I would like to force SSL on the login page and on the page that the CC is entered on. I would prefer to keep the rest of the application free of SSL.
I have the code working to force SSL on certain pages, and remove SSL on others. The problem I have is that if I log in with SSL enabled the user is only authenticated on the pages that are SSL. The reverse holds true as well, if the user logs in without SSL they are only authenticated on pages without SSL.
What can I do to have this persist between the two. Is this using cookies or the session?
Site.Master contiains search form using code below. After pressing submit button entered search string is reset since whole page is re-loaded. How to persist search string so that search field contains enterread value after page is re-loaded ?
I'm implementing IHttpHandler and IRequiresSessionState and I'm using context.Session but after I set up a value in Session, it's lost in the next request. What can I do to persist the values ?
I need a way to save and load the Page State in a persistent manner (Session). The Project i need this for is an Intranet Web Application which has several Configuration Pages and some of them need a Confirmation if they are about to be saved. The Confirmation Page has to be a seperate Page. The use of JavaScript is not possible due to limitations i am bound to. This is what i could come up with so far:
[code]....
I can't seem to find a way to load the Page State after being redirected from the Confirmation.aspx to the PageToConfirm.aspx.
Also, the data on this page is constantly being updated via an UpdatePanel and a Timer control (being re-databound each time). Every 30 seconds the prices displayed for the various stocks in the repeater control change.
Now, I have a linkbutton that has a click event method in the code-behind that is supposed to export the ~data on the screen~ for the user. I need to grab the current values for the list of stocks last databound to the repeater. I can't simply go grab the latest values from the database because those will have been changed in the time between the last refresh.
protected void lbtnExportStocks_Click(object sender, EventArgs e) { // No longer have the stock data used in the repeater control ExportStocksToExcel(); }
I know that ASP.NET doesn't persist the datasource for the repeater on post-back but I need to still be able to either re-construct this list of Stock entities so I can send them the CSV or I need persist it in some way.
I don't want to do anything that is too heavy handed in terms of performance because during certain days of the week this application can have some heavy usage.
What is the proper solution to this type of situation? Should I iterate through the Repeater's "Items" collection and reconstruct the Stock entities?
I am creating a simple web management studio using SMO. Is it secure enough to persist/store user information (login and password for database) using ASP.NET mechanism (e.g. formsauthentication, cookies, etc.). What will be the best practice to do this?
how to persist javascript changes on the server side.For example if I added items to a drop down list client side, how can i persist them in order to read them on the server side.By the way, Telerik control have this feature.
We've worked out some of the tasks on our website can be efficiently solved by maintaining the data using a graph structure. But we don't have much of an idea about how the graph is best persisted. Further we want to write and read simultaneously in an efficient manner in out asp.net app so it needs to handle multiple threads. It doesn't need to be super fast but it needs to be scalable to handle potentially millions of nodes.
I don't want to hack my own system and have heard of Neo4j. Lots of Java developers seem to recommend it to one another. Obviously I'm on the .Net platform and prefer to not have to switch.
What are the available options, particularly on the .Net platform?
On page1.aspx i hava a textbox with id="tb1" On page2.aspx I have a textbox with id="tb2"
page2.aspx is set as postbackurl for page1.aspx. For both labels enabl;eViewState is true. Shouldn't the text I write in page1 also appear in the label on page2? Can I implement this without looking into Request headers, and setting the text myself?
I'm building a web application that has a particular model representing some events. Users need to be able to add N number of people to a given event. Choosing people is handled by a partial view.
I'm trying to build a menu that displays when users click "add a person" to the event. Because the event hasn't been filled out completely yet, there is nothing in the database to persist between requests.
I also have validation logic on the event page.
My proposed solution is to add the form to search or add for people on the event form itself and have a submit button that sends the values that have been added back to the server, where I can store them in ViewData or Session.
Unfortunately, doing this flags the validation.
My second solution is to load a partial view responsible for loading the UI to add/search for a person. I could add a little code on the method in the controller that returns a partial view storing the existing data in a session variable or viewdata. Trouble is, I have to submit the form to do it--again tripping the validation!
I'm wondering if perhaps I chose the wrong tool to do this...because in webforms, there would probably be a postback and you would just perform an operation on that postback. I'd like to avoid rewriting the application in webforms and am wondering if there are ways I'm overlooking in ASP.NET MVC.
Stored procedure just drag here and method are created correspondence that stored procedure.
If i change any thing in any method in dbml file and drag any stored procedure here then All changes are lost.
Means if i change in a method in dbml file. And i drag a new stored procedure in that file then changes are lost and that particular method have its earlier formation that was by default generated by dbml file.
I am storing a key pair in Windows Store, and recently started receiving the "Keyset does not exist" error. Investigating a bit further i found out it could be two things, 1 - The private key is not stored with the persist key set attribute (X509KeyStorageFlags.PersistKeySet) and 2 - access rights to the key. I have tried both 1 and 2 with no success on one machine (in my machine it works apparently). The strange thing is that when i look into MicrosoftCryptoRSAMachineKeys (and S-1-5-18) the key remains there but only for a period of time then it is deleted which means that it is not persisting.
//If decoded then save as RSACryptoServiceProvider newCert.PrivateKey = DecodePrivateKey(privateKeyFile, pkPassword) if (newCert.PrivateKey == null) throw new System.NullReferenceException("Decoded private key resulted in a null reference. Unable to store certificate."); byte[] pfx = newCert.Export(X509ContentType.Pfx); newCert = new X509Certificate2(pfx, string.Empty, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet);
I am running this code on a WCF Service hosted on IIS, and the certificate is deleted even if i give permissions to Network Service, the AppPoolIdentity, my account, etc through MMC-CertMgr. Would anyone know why this happens?
I have a nested master page with radio button controls and one or two dropdowns (depending on the radio button chosen). The dropdown(s) contains either carriers or our customers. If the dropdown type is customer, we display another dropdown to determine what type of customer (current, former, or test). Once a carrier or customer is chosen, an action is called to "set" the customer information in the session. This all works great. The problem is trying to persist the dropdown type, customer type, and customer or carrier chosen over each action/view. Once a customer or carrier is set, the user can chose different menu options (also on the master page) to perform different tasks against the customer or carrier data. I am still fairly new to asp.net mvc and to jquery and ajax. I have racked my brain and tried several different scenarios to get this to work. I tried a master view model which got inherited by the other view models. I couldn't get that to work. Now I am trying a base controller and just setting things in viewdata, but I still can't get it to work once I move to next controller/action/view. Can someone please let me know the best practice for doing this? And or tell me where I'm going wrong? I am at a pretty critical point in this project and am running out of time. The code follows:
I bind textbox to a property of an object. After running the app, if the value of textbox is changed, I expect the object to update this property .This does not happen. I also understand that I am recreating the object from viewstate on postback, which is wrong. how to persist the state of object on postbacks all.
I am trying to figure out how to persist the playing of a Silverlight MediaElement playing within a Silverlight User Control embedded in an ASP.NET during postback.
The scenario goes:
Have a media player on a site, press play, continue navigating through site while the music continues playing.
What it does right now:
Obviously the object gets loaded anew on each postback or page redirect (even if it's back to the same page IE: default.aspx).
I've seen samples of how to persist the state of a Control on postback and even complex data through cross-page postback. But nothing that covers my specific case.
I have a website that needs to store two sets of user data into separate data stores. The first set of data is used by the SiteCore CMS and holds information about the user. The second set of data is used by a personalisation application that stores its own user data. The reason they aren't stored together in the same profile object is because the personalisation application is used across multiple websites that do not all use SiteCore.
I am able to create multiple Profile Providers - I currently have one from SiteCore and a custom provider that I have written and these both work in isolation. The problem exists when you try to configure both in the same web.config file. It seems you can only specify a single Profile object in the web.config file, rather than one for each provider. This means that regardless of which provider is being used the .Net framework sends through the profile object that is specified in the "inherits" parameter in the profile section of the web.config file.
My questions are - Is it possible to specify a different Profile object for each Profile Provider? If so, how and where is this specified?
-edit-
I should point out that there is no duplication of data in the two data sets, they are mutually exclusive (excluding email address). The SiteCore data is used solely for this website, but we have company wide profile data that spans across all of our applications, hence the need for a separate second profile object.
I know that if I re-add the control during Page_Load, the posted values will be repopulated when the page is rendered; however, this is not the case when re-adding the control during the Click event and I need to add the control during an event handler.
how can i persist gridview data after crosspage posting? It seems that every time i visit another page and get back to page the entire gridview data and page index were reset.
Now I inserted some html content inside this div on some button click(without postback) . Now when I perform a postback on some action say on server control submit button , I want the html(which I inserted via javascript) be persisted in the foo div. Right now I am thinking to take an hidden input server control and when the form will be submitted I will insert the content of foo div in that hidden control, the next time when the page loads after the postback I will fill the foo div with the content inside the hidden field. Am I going with correct approach or is their any other good approach which I should opt ?
