  • asp.net mvc create a c# class in an ascx file for design purposes

    - by Julian
    Hi, I am developing a web application using asp.net mvc. I have come across the need to Temporarily create a class in the ascx/aspx file. This class will replace the Model during the development of the page. It will also hold some test data for the user to have the chance to see some results. Once we are happy with the layout on the screen, I will inherit the correct Model class through the Control tag. Can you please advise if this is possible and how to do it? This does not work: <% class Modelo { public Guid Guid { get; set; } public string Name { get; set; } } %> Thanks in advance, Be happy - Julian

  • .NET and P2P - writing a P2P messenger

    - by brovar
    Hi there, Does anyone have any advice how to write such app? Or maybe knows some nice tutorial? I would like to use System.Net.PeerToPeer namespace, but everything I can find about it is MSDN which I can't read without getting mad. Or maybe using "old-school" TCP/IP would more efficient? I will appreciate every piece of advice. Every sample code I will shower with gold ;) And please, don't send me back to Google for I have searched for a long time for sth useful - maybe inaccurately but time is running out and I really need some help.

  • How to dispose NHibernate ISession in an ASP.NET MVC App

    - by Joe Young
    I have NHibernate hooked up in my asp.net mvc app. Everything works fine, if I DON'T dispose the ISession. I have read however that you should dispose, but when I do, I get random "Session is closed" exceptions. I am injecting the ISession into my other objects with Windsor. Here is my current NHModule: public class NHibernateHttpModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += context_BeginRequest; context.EndRequest += context_EndRequest; } static void context_EndRequest(object sender, EventArgs e) { CurrentSessionContext.Unbind(MvcApplication.SessionFactory); } static void context_BeginRequest(object sender, EventArgs e) { CurrentSessionContext.Bind(MvcApplication.SessionFactory.OpenSession()); } public void Dispose() { // do nothing } } Registering the ISession: container .Register(Component.For<ISession>() .UsingFactoryMethod(() => MvcApplication.SessionFactory.GetCurrentSession()).LifeStyle.Transient); The error happens when I tack the Dispose on the unbind in the module. Since I keep getting the session is closed error I assume this is not the correct way to do this, so what is the correct way? Thanks, Joe

  • Asyncronously receiving data in an ASP.NET MVC application

    - by Mitciv
    I'm looking for the best way to constantly check if data has been sent to our ASP.NET MVC application from a server. I would like to asynchronously check for data and update the view when data has been read. I'm currently using a TcpClient to make a connection, and making the connection in the inherited custom base controller. Currently though I have to refresh the page for the updating of the view to take place. Would there be a proper AJAX solution? or do I need to move the connection to the ActionMethod?

  • Referencing code in VB.NET

    - by akramnik
    I'm not at all familiar with VB.NET or ASP. I need to create a simple page which makes a call to a remote web service. I used the wsdl utility which comes with the DotNet SDK to generate a service proxy and write it to a VB file. Unfortunately I have no idea how to reference this code in either my ASPX file or the code behind VB file so I can create an instance of the proxy. Edit: I should have qualified this by noting that I'm not using visual studio. I just coded up a .aspx with a .vb behind it and dropped it into an IIS location. Is there a way to do what you're suggesting outside of VS?

    Hi all, I've create an asp.net MVC 2 project, it works fine!!

  • A checklist for fixing .NET applications to SQL Server timeout problems and improve execution time

    - by avgbody
    A checklist for improving execution time between .NET code and SQL Server. Anything from the basic to weird solutions is appreciated. Code: Change default timeout in command and connection by avgbody. Use stored procedure calls instead of inline sql statement by avgbody. Look for blocking/locking using Activity monitor by Jay Shepherd. SQL Server: Watch out for parameter sniffing in stored procedures by AlexCuse. Beware of dynamically growing the database by Martin Clarke. Use Profiler to find any queries/stored procedures taking longer then 100 milliseconds by BradO. Increase transaction timeout by avgbody. Convert dynamic stored procedures into static ones by avgbody. Check how busy the server is by Jay Shepherd.

  • ASP.NET authentication login and logout with browser back button

    - by Eatdoku
    Hi, I am looking for a solution for user use the browser's back button to navigate to previous page once logged out. I have a web application build in asp.net and using a custom membership provider for authentication and authorization. Everything works fine except when the user click on the logout link to log out of the application and being redirect to a default cover page, if the use click on the BACK BUTTON on their browser, it will actually go back to where they were before and the data will still show up. Of course they can't do anything on that page, click on anything link they will be redirect to a login page again. But having those information display is making a lot users confused. i am just wondering if there is any way i can either clear the browser's history so use can't go BACK, or when they click on the back button and have them redirect to the login page. thanks

  • How are .NET 4 GUIDs generated?

    - by mafutrct
    I am aware of the multitude of questions here as well as Raymond's excellent (as usual) post. However, since the algorithm to create GUIDs was changed apparently, I found it hard to get my hands on any up-to-date information. The MSDN seems to try and provide as few information as possible. What is known about how GUIDs are generated in .NET 4? What was changed, and how does it affect the security ("randomness") and integrity ("uniqueness")? One specific aspect I'm interested in: In v1, it seems to be about impossible to generate the same GUID on a single machine again since there was a timestamp and counter involved. In v4, this is no longer the case (I was told), so the chance to get the same GUID on a single machine ... increased?

  • Asp.Net Program Architecture

    - by Pino
    I've just taken on a new Asp.Net MVC application and after opening it up I find the following, [Project].Web [Project].Models [Project].BLL [Project].DAL Now, something thats become clear is that there is the data has to do a hell of a lot before it makes it to the View (DatabaseDALRepoBLLConvertToModelControllerView). The DAL is Subsonic, the repositorys in the DAL return the subsonic entities to the BLL which process them does crazy things and converts them into a Model (From the .Models) sometimes with classes that look like this public DataModel GetDataModel(EntityObject Src) { var ReturnData = new DataModel(): ReturnData.ID = Src.ID; ReturnDate.Name = Src.Name; //etc etc } Now, the question is, "Is this complete overkill"? Ok the project is of a decent size and can only get bigger but is it worth carrying on with all this? I dont want to use AutoMapper as it just seems like it makes the complication worse. Can anyone shed any light on this?

  • Determine the colours used by the ASP.NET Chart control

    - by Moose Factory
    I'd like to find out which colours are used for a particular pallette in the ASP.NET Chart control. I already know there is an enum on the Chart class to set the palette, e.g. myChart.Palette = ChartColorPalette.Berry; But I'd like to know which colours belong to the palette. Before anyone asks - as I know you will - the reason I need to know the colours is because I want to create my own legend outside of the chart image. I also know that I can set my own colours on the DataPoints for the chart, but I'd rather not have to implement my own palette.

  • Avoiding the Controller with Routing Rules in ASP.NET MVC

    - by Ryan Elkins
    I've created a website with ASP.NET MVC. I have a number of static pages that I am currently serving through a single controller called Home. This creates some rather ugly URLs. example.com/Home/About example.com/Home/ContactUs example.com/Home/Features You get the idea. I'd rather not have to create a controller for each one of these as the actions simply call the View with no model being passed in. Is there a way to write a routing rule that will remove the controller from the URL? I'd like it to look like: example.com/About example.com/ContactUs example.com/Features If not, how is this situation normally handled? I imagine I'm not the first person to run in to this.

  • Storing Interface type in ASP.NET Profile

    - by NathanD
    In my ASP.NET website all calls into the data layer return entities as interfaces and the website does not need to know what the concrete type is. This works fine, but I have run into a problem when trying to store one of those types into the user Profile. My interface implements ISerializable, like the following: public interface IInsured : IPerson, IEntity, ISerializable and the concrete type in the datalayer does implement ISerializable. My Profile property in web.config is: <add name="ActiveInsured" type="FacadeInterfaces.IInsured" serializeAs="Binary" defaultValue="[null]"/> It compiles just fine, but I get a runtime error on Profile.Save() saying that the interface cannot be serialized. I have also tried it with serializeAs="Xml". I thought that if my interface implemented ISerializable it would work. Anybody had this problem before or know of a workaround?

  • CruiseControl failing view compilation with Asp.net MVC 2 RTM

    - by Robert Koritnik
    Tehnologies: - CruiseControlNet - Asp.net MVC 2 RTM - enabled view compilation The problem is UrlParameter.Optional setting. I can't seem to make it work when I use this setting inside a view. When I compile inside Visual Studio, everything works fine, but when CCNet uses MSBuild to compile it it fails with following error: errorCS0103: The name 'UrlParameter' does not exist in the current context pointing to the line inside my view where this parameter is set on: Html.RenderAction(...) that sets certain route parameter(s) to optional. I tried adding <%@ Assembly name="System.Web.Mvc" %> at the top of my view, but it didn't work either. It works of course when I disable view compilation, but that's not really an option. And I also don't want to set my optional parameters to string.Empty. Anyone has any hint on this?

  • .NET 4.0 project reference 2.0 assembly

    - by jamone
    I have a project in which I'd like to use some of the .NET 4.0 features but a core requirement is that I can use the System.Data.SQLite framework which is compiled against 2.X. I see mention of this being possible such as the accepted answer here but I don't see how to actually achieve this. When I just try and run my 4.0 project while referencing the 2.X assembly I get: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. What "additional configuration" is necessary?

  • ASP.NET MVC 2 Areas 404

    - by Justin
    Hey, Has anyone been able to get the Areas in ASP.NET MVC 2 to work? I created a new Area called "Secure" and placed a new controller in it named HomeController. I then Created a new Home/Index.aspx view. However, when I browse to http://localhost/myapp/Secure/ it gives a 404 resource cannot be found. http://localhost/myapp/Secure/Home gives the same error. My area registration looks like this: public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Secure_default", "Secure/{controller}/{action}/{id}", new { action = "Index", id = UrlParameter.Optional } ); } I also tried this: public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Secure_default", "Secure/{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); } Thanks, Justin

  • Keep an object for the time the connection is running in ASP.NET

    - by vtortola
    Hi, I'm developing a web service with ASP.NET, is not an .asmx or WCF, it's a custom one, so I'm working with the Http classes (context, request, response, etc..). Session is disabled. I'm working with my own handler and module. I'd like to keep a object alive and accessible for the time the connection is alive. I mean, a request enters, I assign a DbCommand to it and that connection will use that command as long is doing things, when that connection is ended, the object should be disposed. I've thought, that I can add it to my IPrincipal implementation, then when the connection is authenticated in the module and the user retrieved, I can add that DbCommand to the IPrincipal, so I can retrieve it from wherever I want in the code, and after in the module EndRequest event, I can dispose it, but I don't know if there is a better approach to do this. What do you think? cheers

  • ASP.NET MVC 2 - Account controller not found

    - by Chris
    Hi all, I've recently created an ASP.NET MVC 2 application, which works perfectly in the development environment. However, when I deploy it to the server (123-reg Premium Hosting), I can access all of the expected areas - except the Account controller (www.host.info/Account). This then attempts to redirect to the Error.aspx page (www.host.info/Shared/Error.aspx) which it cannot find. I've checked that all of the views have been published, and they're all in the correct place. It seems bizarre that two other controllers can be accessed with no problems, whereas the Account controller cannot be found. I have since renamed the AccountController to SecureController, and all of the dependencies, to no avail. The problem with not being able to find the Error.aspx page also occurs on the development environment. Any ideas would be greatly appreciated. Thanks, Chris

  • WCF is throwing UnauthorizedAccessExceptyion after upgrade to .NET 4.0

    - by Andrey
    I have a pretty simple client-server ASP.NET app; communication is via WCF service. All worked perferctly inVS 2008, now I upgraded to VS2010 and every time the client code is trying to instantiate a channel to the server: new ChannelFactory<IMemberService>("Members.MemberService").CreateChannel(); it throws an UnauthorizedAccessException "Access denied". Were there any breaking changes in the new version, or do I need to add some configuration? I'm pretty stuck, any ideas would be highly appreciated! BTW, binding used is basicHttpBinding, i don't know if thats important here. Thank you, Andrey

  • Personalization in ASP.Net MVC -- friendly URLs, and skinning

    - by larryq
    Hi everyone, I haven't delved into custom generation of friendly URLs in ASP.Net MVC, and was wondering if anyone had suggestions. For example, if John Smith were to create an account on www.example.com, I'd like for his homepage to read www.example.com/JohnSmith -- along with the option for him to choose his URL. The ideal is for this to happen with no intervention on my part in the route maps. Also, does anyone have guidelines on good ways to go to customize an MVC site based on URL? Again, using example.com I'd like for John to choose a color theme and logo for his homepage, then apply it accordingly. Thanks for your tips and suggestions.

  • ASP.NET MVC Best Implementation Practices

    - by RSolberg
    I've recently been asked to completely rewrite and redesign a web site and the owner of the company has stressed that he wants the site to be made with the latest and greatest technology available, but to avoid additional costs. As of right now, I'm torn between looking into a CMS implementation and writing a new implementation with MVC. The site is mainly brochure ware, but will need to allow the visitors to submit some data through forms. There are quite a few lists and content features that are dynamic and should be treated as such. Since ASP.NET MVC is new, I don't want to bastardize the implementation if I go that way... Any recommendations on best implementation practices for a MVC website? Also, has anyone had their MVC implementation hosted anywhere that they would recommend?

  • When are ASP.NET Expression Builders most useful?

    - by SkippyFire
    I saw an example of using Expression Builders, and creating your own Custom Expression Builder Classes here: http://aspnet.4guysfromrolla.com/articles/022509-1.aspx However, I fail to see the value in using this approach. It doesn't seem much easier than programmatically setting values in your code behind. As far as I can tell, the only thing you can do with them is set properties. Maybe they would be useful for setting defaults on certain controls? Can anyone shed light on where this ASP.NET feature becomes powerful?

    i see the new feature of areas in asp.net-mvc 2. it got me thinking. why would i need this? i did some reading on the use cases and it came down to a specific point to me around how big and how broad scope should my controllers should be? should i try to have many little controllers? one big controller? how do people determine the sweet spot for number of controllers? i think mine are maybe too large (which had me questioning areas in the first place as maybe my controller name should really be an area and have a number of smaller controllers)

  • ASP.NET CompositeControl with child controls that contain children

    - by tomfanning
    I am building an ASP.NET server control which extends CompositeControl. I need fine grained control over the rendering, so I override Render() and output the child controls myself, interspersed with HTML generation code: writer.AddStyleAttribute("float", "left"); writer.RenderBeginTag(System.Web.UI.HtmlTextWriterTag.Div); writer.RenderBeginTag(System.Web.UI.HtmlTextWriterTag.Strong); writer.Write("Table"); writer.RenderEndTag(); // strong writer.WriteBreak(); tableList.RenderControl(writer); writer.RenderEndTag(); // div This works really well for user controls that just contain simple controls without children of their own. However, if I want to use something like a MultiView or an UpdatePanel I run into problems, since I can't override Render() on View or UpdatePanel without extending them, and if I do extend them the implementation would presumably have to depend on FindControl() voodoo to get references to the right controls during render. That doesn't sound like the right way to do this - is there a better way?

  • ASP.NET 3.5 Web Site stopped importing System namespace by default

    - by Alexis
    I have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default. I'm having to either place a "Imports System" line at the top of each code behind, or preface everything with "System", which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default. I've already checked to see that WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web.config contains the <add namespace="System"/> line--it does. That was my best lead. I'm tearing my hair out. Does anyone have any suggestions?
