  • How to store account-specific information in ASP.NET MVC 2

    - by PR_
    I have an ASP.NET MVC 2 web application. There are two tables like "FIRST_KIND_OF_USERS" and "SECOND_KIND_OF_USERS". Both are mapped to the default aspnet_users table via UserId column. Each of them has it's own integer primary key column like "FirstKindOfUsersId". When a user is trying to add some data to the database, for instance, "Create a new Task" I would like to add a new row in Tasks table with "FirstKindOfUsersId" value. Where should I store or get this value? At the moment I have these possible solutions: Get "FirstKindOfUsersId" value by User.Identity.Name each time; Use SESSION[] for storing these values (Where and when should I save these ones?) Use FormsAuthenticationTicket and create own custom IIdentity class. (http://stackoverflow.com/questions/1064271/asp-net-mvc-set-custom-iidentity-or-iprincipal) Which approach is better? And if I pick the 3rd one, how to save the necessary data property and at which stage?

  • ASP.NET MVC - ASPX with non-default constructor

    - by bh213
    Is it possible for a ASPX view (in ASP.NET MVC) to have non-default constructor AND use this constructor when creating this view? Example - Page will inherit from this class: public class ViewPageWithHelper<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class { public ViewPageWithHelper(Helpers helpers) { Helpers = helpers; } protected Helpers Helpers { get; private set; } } ASPX view: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="MyInjectedViewPage<MyModel>" %> <% Helpers.XXXX %> Now, I'd like to inject Helpers into view somehow - automatically. Ideas?

  • Loading the last related record instantly for multiple parent records using Entity framework

    - by Guillaume Schuermans
    Does anyone know a good approach using Entity Framework for the problem described below? I am trying for our next release to come up with a performant way to show the placed orders for the logged on customer. Of course paging is always a good technique to use when a lot of data is available I would like to see an answer without any paging techniques. Here's the story: a customer places an order which gets an orderstatus = PENDING. Depending on some strategy we move that order up the chain in order to get it APPROVED. Every change of status is logged so we can see a trace for statusses and maybe even an extra line of comment per status which can provide some extra valuable information to whoever sees this order in an interface. So an Order is linked to a Customer. One order can have multiple orderstatusses stored in OrderStatusHistory. In my testscenario I am using a customer which has 100+ Orders each with about 5 records in the OrderStatusHistory-table. I would for now like to see all orders in one page not using paging where for each Order I show the last relevant Status and the extra comment (if there is any for this last status; both fields coming from OrderStatusHistory; the record with the highest Id for the given OrderId). There are multiple scenarios I have tried, but I would like to see any potential other solutions or comments on the things I have already tried. Trying to do Include() when getting Orders but this still results in multiple queries launched on the database. Each order triggers an extra query to the database to get all orderstatusses in the history table. So all statusses are queried here instead of just returning the last relevant one, plus 100 extra queries are launched for 100 orders. You can imagine the problem when there are 100000+ orders in the database. Having 2 computed columns on the database: LastStatus, LastStatusInformation and a regular Linq-Query which gets those columns which are available through the Entity-model. The problem with this approach is the fact that those computed columns are determined using a scalar function which can not be changed without removing the formula from the computed column, etc... In the end I am very familiar with SQL and Stored procedures, but since the rest of the data-layer uses Entity Framework I would like to stick to it as long as possible, even though I have my doubts about performance. Using the SQL approach I would write something like this: WITH cte (RN, OrderId, [Status], Information) AS ( SELECT ROW_NUMBER() OVER (PARTITION BY OrderId ORDER BY Id DESC), OrderId, [Status], Information FROM OrderStatus ) SELECT o.Id, cte.[Status], cte.Information AS StatusInformation, o.* FROM [Order] o INNER JOIN cte ON o.Id = cte.OrderId AND cte.RN = 1 WHERE CustomerId = @CustomerId ORDER BY 1 DESC; which returns all orders for the customer with the statusinformation provided by the Common Table Expression. Does anyone know a good approach using Entity Framework?

  • What version of DataAnnotations is included with ASP.NET MVC 2 RTM

    - by Nick Thoresby
    I'm working on a project using Visual Studio 2008 and have moved from the the MVC 2 Preview to RTM version. We would like to use model validation such as: public class ViewModel { [Required(ErrorMessage="UserName is required.")] [StringLength(10, ErrorMessage="UserName cannot be greater than 10 chars.")] public string UserName { get; set; } } [HttpPost] public ActionResult Register(ViewModel model) { if (ModelState.IsValid){} // Always true } However the ModelState.IsValid always returns true. I have a suspicion that it might be something to do with the version of System.ComponentModel.DataAnnotations.dll that we are referencing, currently version 99.0.0.0, which seems rather odd. Does anyone know what version of this dll is included with the MVC 2 RTM for Visual Studio 2008?

  • Should I use Drupal or Kohana-type framework for a web "application"

    - by Andres
    The debate is that I need a PHP Framework/Drupal with the flexibility to add custom features to a potentially large application (web and with an api). However, with a framework, like Kohana, I see myself tackling and re-inventing the wheel with the simple stuff like account management and cms stuff. Account management and quick data collection, like fast form creation, are tedious in Kohana but appear incredible simple in Drupal. On the other hand, based on my limited Drupal experience, I doubt building rapid custom "features" and allowing users to create "groups" and to manage their own roles within those groups is something Drupal can easily accomplish. To simplify, is Drupal capable of true Web Applications; where the application is a service and provides custom results to each user? Can it provide a dashboard-like interface for users to change their settings or preferences? Can it aggregate data from particular users to provide better results/info to others? If so, please point me to some knowledge :-)

  • what is a performance way to 'tree-walking' through my Entity Framework data

    - by Greg
    Hi, I have a Entity Framework design with a few tables that define a "graph". So there can be a large chain of relationships between objects in the few tables via concept of parent/child relationships. What is a performance way to 'tree-walking' through my Entity Framework data? That is I assume I wouldn't want to load the full set of all NODES and RELATIONSHIPS from the database for the purpose of walking the tree, where the end result may only be identifying leaf nodes? Or would this be OK with the way lazy loading may work at the column/parameter level? Else how could I load just the skeleton of the objects and then when needing to refer to any attributes have them lazy load then?

  • Running ASP.NET MVC application behind a proxy with different root relative path

    - by Wiebe
    Hi All, I'm having trouble with paths in a ASP.NET MVC application that's running behind a proxy. Our IIS Application root path is for example http://server/MyApp/ meaning that all urls using the application root ("~/",Url.Action("MyAction","MyController")) are resolved to "/MyApp" Now we're running behind a proxy server that forwards all requests, but changes the application root to something like this: "/Secury/Proxy/RubbishUrl/MyApp" Because the original url is only available on the client, I thought of creating a cookie with the path prefix, and insert this before each generated URL on the server. Now the question is, what's the best location in code to modify each URL that's resolved/sent to the client (to resources, controller actions, images etc)? Every path in the application is resolved with the MVC methods (Url.Content, Url.Action etc).

  • Blog engines for ASP.Net (maybe MVC) web sites

    - by J. Pablo Fernández
    I've built a web site on ASP.NET MVC and one little section of it should be a blog. I'm looking for a blog to integrate. In the worst case scenario it'd be a WordPress with a custom skin and RSS integration to the rest of the site. The best would be to have an ASP.NET MVC add-on, but I can live with ASP.NET WebForms. Do you have any recomendations on the engine? I've been checking out BlogEngine.Net and I'd like to have some other ideas to compare. Anything in particular you can point to regarding this integration?

  • google docs for asp.net mvc

    - by Yaroslav Yakovlev
    Where can I get code example of using google docs with asp.net mvc? I need to upload documents and make it possible for people to download them. Also would be just great to make it possible to see the documents like I see them on google docs and be able to edit (probably use iFrame) but would like to get working example or some tips to get started. Code pieces are greatly appreciated, upvoted and marked as answer ;-), but I~ll be enought with a good starting points. P.S. I~m aware of google have docs for their api :-). Just looking for other places to start from. Codeproject article or github repo of api used with asp.net mvc would be the best.

  • System.Web.HttpException in asp.net mvc 2 on images and javascript files

    - by Rippo
    Hi I am getting the following errors reported by ELMAH on my asp.net mvc 2 site for javascript files, images etc. System.Web.HttpException: The remote host closed the connection I have done some research and it appears that the user/bot is clicking a link on the site before the page has fully loaded. Now this error never occurs on a controller action but always on a file that is on disk. e.g. /Content/CmsImages/logo.png /Content/CmsImages/MemberImages/Photo-001605.jpg /Content/jquery.tickertype.js So this means that all static files are being routed through the mvc pipeline. What options do I have?

  • Spring MVC with several configurations

    - by Michael Bulla
    Hello, for my spring-mvc application I created several types of configuration (unittest, integration, qa, production). All the configs are in one war-file, so there is only one type of application I create. Which configuration to take should be decided by the server, where the application is running. To decide what kind of configuration should be used, I have to look into a file. After that I can decide which configuration should be used by spring mvc. For now by convention there is always the -servlet.xml used. Is there a way how to decide dynamically which config to take? Regards, Michael

  • Entity framework and database logic.

    - by Xavier Devian
    Hi all, i have a question that's being around for several years. As all you know entity framework is an ORM tool that tries to model the database to an object oriented access model. All the samples I've seen are quering directly to the database tables. So, which is the role of the views in the database now?. The views were used to model the database in a more friendly way, that is, several physical tables, one logic table. This was great for example in hidding the complex relational model on stored procedures as queryng the views inside them was much easier than reproducing the query joins over and over on each stored procedure. So the question is, why is entity framework so good if stored procedures can not take benefit of it?

  • Salting example in Zend Framework

    - by Geoffrey
    Hello all, I am pretty new to the Zend framework and looking to build an application with pretty tight password security. I have been trying to follow the user guides in relation to password salting but haven't had any luck so far. I have setup my database and table adapter (As described in the documentation on the Zend Framework site but it didn't seem to finish the example (or I am not following well enough!) I have started with: $authAdapter = new Zend_Auth_Adapter_DbTable($dbAdapter, 'users', 'username', 'password', "MD5(CONCAT('".Zend_Registry::get('staticSalt')."', ?, password_salt))" ); But from here, what is done with the password salt? I just need an example and I'll be away! Does anyone have an example or point me in the right direction?? Many thanks!

  • Referencing View directory in asp.net mvc

    - by ooo
    i have some html files as part of a regular website that has been ported over to asp.net mvc. In my code i need to read and write these html files and stick them in a tinymce editor To be able to read and write this file from disk in the past i had a hard coded path but this doesn't seem to work in asp.net mvc unless i do something like this: Writing: string _urlDirectory = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; System.IO.File.WriteAllText(_urlDirectory, htmlData_); Reading: string url = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; var req = WebRequest.Create(url); var response = req.GetResponse(); StreamReader sr = new StreamReader(response.GetResponseStream()); string htmlData_ = sr.ReadToEnd(); i am moving my site from one data center to another and the directory structure is changing. instead of just changing the hard coded path to another hard coded path i wanted to see if there was a more relative way to reference these files.

  • Playing flash video with ASP.NET MVC

    - by evan
    What's a good flash player to use on an ASP.NET MVC site? The page I'm working on will need to display a number of videos on each page dynamically based on what the user searched for. I'd like each of the videos to show up as thumbnails that can be played, paused, and or enlarged to full screen. I've worked with the standard ASP.NET and used FlashControl.dll to accomplish this. Are there better ways than using a user control for MVC pages? Any tips on including video in webpages in general? Thanks in advance!

  • ASP.NET MVC Generic Controllers and Spring.NET

    - by Jason
    Hello, I am creating an application using ASP.NET MVC (2) and Spring.NET. Since most of my Controller implementations just implement the similar CRUD operations, I would like to just create a single Generic controller, as explained here: http://stackoverflow.com/questions/848904/in-asp-net-mvc-is-it-possible-to-make-a-generic-controller However, the above example doesn't take DI frameworks into consideration. What I'm thinking is to create this (warning: this is an ugly mass of code I need help with): public SpringGenericControllerFactory : DefaultControllerFactory { public IController CreateController(RequestContext requestContext, string controllerName) { // Determine the controller type to return Type controllerType = Type.GetType("MyController").MakeGenericType(Type.GetType(controllerName)); // Return the controller return Activator.CreateInstance(controllerType) as IController; } } The entries in objects.xml would look something like this: <object id="controllerFactory" type="Application.Controllers.SpringGenericControllerFactory" /> <object id="DepartmentController" factory-method="CreateController" factory-object="controllerFactory" /> Can anyone pick through this and offer advice?

  • ASP.net MVC: Getting a Partial View's HTML from inside of the controller

    - by Harry
    I have developed a simple mechanism for my mvc website to pull in html via jquery which then populates a specified div. All is well and it looks cool. My problem is that i'm now creating html markup inside of my controller (Which is very easy to do in VB.net btw) I'd rather not mix up the sepparation of concerns. Is it possible to use a custom 'MVC View User Control' to suit this need? Can I create an instance of a control, pass in the model data and render to html? It would then be a simple matter of rendering and passing back to the calling browser.

  • ASP.NET MVC, JSON & non JavaScript clients

    - by redsquare
    I need to ensure that an application I am developing is accessable and also works with JavaScript turned off. I just need a pointer to assist with the following. I had 3 'chained' select boxes and I wanted JavaScript enabled clients to have a nice Ajax experience. I can easily write the required functionality to populate the chained boxes on the change event of the preceeding select using jQuery and JSON with a WCF service. However what about the non JavaScript client? Would I wrap a submit next to the select and place these inside their own form to post back with a certain action or different querstring parameter? Can the same controller give me a partial JSON response as well as feeding the full HTML response. Can anyone point me to a good demo that utilises both JSON and normal HTTP posts to produce the same result in ASP.NET MVC. All ASP.NET MVC demo/examples I see forget about the non JavaScript enabled client.

    - by bplus
    I'm trying to create an editable grid using Asp.Net MVC 2 and Silverlight (specifically a grid that displays info from a db and allows users to update that info). So far I've managed to put a silverlight grid on an a view, using this technique However I have no way of getting the updated data from the silver light grid. Is there anyway to get these values posted back to my controller? I'm pretty new to Asp.Net MVC and I'm really only getting started using silverlight. Thanks for any help!
