  • asp .net MVC 2.0 Validation

    - by ANDyW
    Hi I’m trying to do some validation in asp .net MVC 2.0 for my application. I want to have some nice client side validation. Validation should be done most time on model side with DataAnnotations with custom attributes( like CompareTo, StringLenght, MinPasswordLenght (from Membership.MinimumumpassworkdLenght value). For that purpose I tried to use xval with jquery.validation. Some specific thing is that most of forms will be working with ajax and most problems are when I want to validate form with ajax. Here is link for sample project http://www.sendspace.com/file/m9gl54 . I got two forms as controls ValidFormControl1.ascx, ValidFormControl2.ascx <% using (Ajax.BeginForm("CreateValidForm", "Test", new AjaxOptions { HttpMethod = "Post" })) {%> <div id="validationSummary1"> <%= Html.ValidationSummary(true)%> </div> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.Name)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Name)%> <%= Html.ValidationMessageFor(model => model.Name)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Email)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Email)%> <%= Html.ValidationMessageFor(model => model.Email)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Password)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Password)%> <%= Html.ValidationMessageFor(model => model.Password)%> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.ConfirmPassword)%> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.ConfirmPassword)%> <%= Html.ValidationMessageFor(model => model.ConfirmPassword)%> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> <%= Html.ClientSideValidation<ValidModel>() .UseValidationSummary("validationSummary1", "Please fix the following problems:") %> Both look same the difference is only validation summaryID (validationSummary1, validationSummary2). Both controls are rendered on one page : Form2 <%Html.RenderPartial("~/Views/Test/ValidFormControl2.ascx", null); %> Form1 <%Html.RenderPartial("~/Views/Test/ValidFormControl.ascx", null); %> Validation property First problem, when we have two controls with same type to validate it don’t work becosue html elements are rendered by field name ( so we have two element with same name “Password” ). Only first form will be validated by client side. The worst thing is that even if we have different types and their fields name is same validation won’t work too ( this thing is what I need to repair it will be stupid to name some unique properites for validation ). Is there any solution for this ? Custom attributes validation Next thing custom attributes validation ( All those error are when I use Ajax for on normal form validation is working without problem. ): CompareTo - Simple compare to that is done in mvc template for account model ( class attribute saying with two property will be compared ) , and it wasn’t show on page. To do it I created own CachingRulesProvider with compareRule and my Attribute. Maybe there is more easy way to do it? StringLenght with minimum and maximum value, I won’t describe how I done it but is there any easy whey to do it? Validation summary When I have two two control on page all summary validation information goes to first control validation summary element, even xval generated script say that elementID are different for summary. Any one know how to repair it? Validation Information Is there any option to turn on messages on place where is Html.ValidationMessageFor(model = model.ConfirmPassword). Becsoue for me it isn’t show up. I would like to have summary and near field information too not only red border. Any one know how to do it? Ajax submit Anyone know how to do easy without massive code in javascript to do submit via javascript. This will be used to change input submit to href element (a). Both look same the difference is only validation summaryID

  • How to figure out why .NET app runs at 32-bit on a 64-bit machine

    - by user54064
    I have a .NET app (webforms - .NET 3.5) that is running on a 64-bit server as 32-bit (I checked the IntPtr.Size result). The compilation is set to AnyCPU so I would expect that on a 64-bit machine, the app would be run at 64-bit. There are many Third-party programs incorporated into the app, could they be causing a problem? How do I figure out why 64-bit compilation is not being done?

  • .Net adding a prefix ctl00_CPHPageContents_ to control IDs

    - by eFriend
    I have an asp.net C# web forms application in .net framework 4 In my pages, when I view html source it changes control IDs to something like ctl00_CPHPageContents_txtUserID actually it is txtUserID This application was first in Framework 3.5 and IDs were generated like CPHPageContents_txtUserID So, in short, in Framework 3.5 Id was CPHPageContents_txtUserID and now in Framework 4 ID is ctl00_CPHPageContents_txtUserID which is breaking our automation tests. Can I remove this ctl00 added by Framework 4?

  • Localization of attribute values in .NET

    - by Alex Angas
    How can I localize/internationalize attribute values in .NET? My specific example is for ASP.NET web parts such as WebDisplayName, WebDescription, etc. where I inherit from the base class that uses these attributes. Also, is there any difference to doing this with attributes declared in my own classes? Thanks!

  • cloud computing in .net 4.0

    - by HotTester
    Since the launch of .net 4.0 the buzz word has been cloud computing. But very little is said and discussed about it in perspective of .net technologies. Further is it really the worth to invest or do we have sufficient current technologies that can handle what cloud computing offers ? Can you please describe it and an example would be quite helpful ! Thanks in advance.

  • A small, intra-app Object to String Serializer

    - by Rick Strahl
    On a few occasions I've needed a very compact serializer for small and simple, flat object serialization, typically for storage in Cookies or a FormsAuthentication ticket in ASP.NET. XML and JSON serialization are too verbose for those scenarios so a simple property serializer that strings together the values was needed. Originally I did this by hand, but here is a class that automates the process.

  • What do you do when a client requires Rich Text Editing on their website?

    - by George Stocker
    As we all know by now, XSS attacks are dangerous and really easy to pull off. Various frameworks make it easy to encode HTML, like ASP.NET MVC does: <%= Html.Encode("string"); %> But what happens when your client requires that they be able to upload their content directly from a Microsoft Word document? Here's the scenario: People can copy and paste content from Microsoft word into a WYSIWYG editor (in this case tinyMCE), and then that information is posted to a web page. The website is public, but only members of that organization will have access to post information to a webpage. What is the best way to handle this requirement? Currently there is no checking done on what the client posts (since only 'trusted' users can post), but I'm not particularly happy with that and would like to lock it down further in case an account is hacked. The platform in question is ASP.NET MVC. The only conceptual method that I'm aware of that meets these requirements is to whitelist HTML tags and let those pass through. Is there another way? If not, is the best way to let them store it in the Database in any form, but only display it properly encoded and stripped of bad tags? NB: The questions differ in that he only assumes there's one way. I'm also asking the following questions: 1. Is there a better way that doesn't rely on HTML Whitelists? 2. Is there a better way that relies on a different view engine? 3. Is there a WYSIWYG editor that includes the ability to whitelist on the fly? 4. Should I even worry about this since it will only be for 'private posting' (Much in the same way that a private blog allows HTML From the author, but since only he can post, it's not an issue)? Edit #2: If suggesting a WYSIWYG editor, it must be free (as in speech, or as in beer). Update: All of the suggestions thus far revolve around a specific Rich Text Editor to use: Only provide an editor as a suggestion if it allows for sanitization of HTML tags; and it fulfills the requirement of accepting pasted documents from a WYSIWYG Editor like Microsoft Word. There are three methods that I know of: 1. Not allow HTML. 2. Allow HTML, but sanitize it 3. Find a Rich Text Editor that sanitizes and allows HTML. The previous questions remain (1-4 above).

  • ASP.NET MVC 3 Hosting :: Error Handling and CustomErrors in ASP.NET MVC 3 Framework

    - by C. Miller
    So, what else is new in MVC 3? MVC 3 now has a GlobalFilterCollection that is automatically populated with a HandleErrorAttribute. This default FilterAttribute brings with it a new way of handling errors in your web applications. In short, you can now handle errors inside of the MVC pipeline. What does that mean? This gives you direct programmatic control over handling your 500 errors in the same way that ASP.NET and CustomErrors give you configurable control of handling your HTTP error codes. How does that work out? Think of it as a routing table specifically for your Exceptions, it's pretty sweet! Global Filters The new Global.asax file now has a RegisterGlobalFilters method that is used to add filters to the new GlobalFilterCollection, statically located at System.Web.Mvc.GlobalFilter.Filters. By default this method adds one filter, the HandleErrorAttribute. public class MvcApplication : System.Web.HttpApplication {     public static void RegisterGlobalFilters(GlobalFilterCollection filters)     {         filters.Add(new HandleErrorAttribute());     } HandleErrorAttributes The HandleErrorAttribute is pretty simple in concept: MVC has already adjusted us to using Filter attributes for our AcceptVerbs and RequiresAuthorization, now we are going to use them for (as the name implies) error handling, and we are going to do so on a (also as the name implies) global scale. The HandleErrorAttribute has properties for ExceptionType, View, and Master. The ExceptionType allows you to specify what exception that attribute should handle. The View allows you to specify which error view (page) you want it to redirect to. Last but not least, the Master allows you to control which master page (or as Razor refers to them, Layout) you want to render with, even if that means overriding the default layout specified in the view itself. public class MvcApplication : System.Web.HttpApplication {     public static void RegisterGlobalFilters(GlobalFilterCollection filters)     {         filters.Add(new HandleErrorAttribute         {             ExceptionType = typeof(DbException),             // DbError.cshtml is a view in the Shared folder.             View = "DbError",             Order = 2         });         filters.Add(new HandleErrorAttribute());     }Error Views All of your views still work like they did in the previous version of MVC (except of course that they can now use the Razor engine). However, a view that is used to render an error can not have a specified model! This is because they already have a model, and that is System.Web.Mvc.HandleErrorInfo @model System.Web.Mvc.HandleErrorInfo           @{     ViewBag.Title = "DbError"; } <h2>A Database Error Has Occurred</h2> @if (Model != null) {     <p>@Model.Exception.GetType().Name<br />     thrown in @Model.ControllerName @Model.ActionName</p> }Errors Outside of the MVC Pipeline The HandleErrorAttribute will only handle errors that happen inside of the MVC pipeline, better known as 500 errors. Errors outside of the MVC pipeline are still handled the way they have always been with ASP.NET. You turn on custom errors, specify error codes and paths to error pages, etc. It is important to remember that these will happen for anything and everything outside of what the HandleErrorAttribute handles. Also, these will happen whenever an error is not handled with the HandleErrorAttribute from inside of the pipeline. <system.web>  <customErrors mode="On" defaultRedirect="~/error">     <error statusCode="404" redirect="~/error/notfound"></error>  </customErrors>Sample Controllers public class ExampleController : Controller {     public ActionResult Exception()     {         throw new ArgumentNullException();     }     public ActionResult Db()     {         // Inherits from DbException         throw new MyDbException();     } } public class ErrorController : Controller {     public ActionResult Index()     {         return View();     }     public ActionResult NotFound()     {         return View();     } } Putting It All Together If we have all the code above included in our MVC 3 project, here is how the following scenario's will play out: 1.       A controller action throws an Exception. You will remain on the current page and the global HandleErrorAttributes will render the Error view. 2.       A controller action throws any type of DbException. You will remain on the current page and the global HandleErrorAttributes will render the DbError view. 3.       Go to a non-existent page. You will be redirect to the Error controller's NotFound action by the CustomErrors configuration for HTTP StatusCode 404. But don't take my word for it, download the sample project and try it yourself. Three Important Lessons Learned For the most part this is all pretty straight forward, but there are a few gotcha's that you should remember to watch out for: 1) Error views have models, but they must be of type HandleErrorInfo. It is confusing at first to think that you can't control the M in an MVC page, but it's for a good reason. Errors can come from any action in any controller, and no redirect is taking place, so the view engine is just going to render an error view with the only data it has: The HandleError Info model. Do not try to set the model on your error page or pass in a different object through a controller action, it will just blow up and cause a second exception after your first exception! 2) When the HandleErrorAttribute renders a page, it does not pass through a controller or an action. The standard web.config CustomErrors literally redirect a failed request to a new page. The HandleErrorAttribute is just rendering a view, so it is not going to pass through a controller action. But that's ok! Remember, a controller's job is to get the model for a view, but an error already has a model ready to give to the view, thus there is no need to pass through a controller. That being said, the normal ASP.NET custom errors still need to route through controllers. So if you want to share an error page between the HandleErrorAttribute and your web.config redirects, you will need to create a controller action and route for it. But then when you render that error view from your action, you can only use the HandlerErrorInfo model or ViewData dictionary to populate your page. 3) The HandleErrorAttribute obeys if CustomErrors are on or off, but does not use their redirects. If you turn CustomErrors off in your web.config, the HandleErrorAttributes will stop handling errors. However, that is the only configuration these two mechanisms share. The HandleErrorAttribute will not use your defaultRedirect property, or any other errors registered with customer errors. In Summary The HandleErrorAttribute is for displaying 500 errors that were caused by exceptions inside of the MVC pipeline. The custom errors are for redirecting from error pages caused by other HTTP codes.

  • How can you know what is w3wp.exe doing? (or how to diagnose a performance problem)

    - by Daniel Magliola
    I'm having a performance problem in a site we've made, and I'm not exactly sure how to start diagnosing it. The short description is: We have a very small site (http://hearablog.com) with very little traffic, in a crappy dedicated server, CPU is always very high, sometimes it stays at 100% for minutes, and w3wp.exe is taking most of it. A typical scenario is w3wp.exe takes 60%, and SQL Server takes about 30%. Our DB is pretty small too. Long description and more details: The site is hosted in a very crappy server by Cari.Net. From the beginning we had the feeling that the server didn't quite behave correctly, like some things would take just too long, so this could be a configuration problem from the get go. It may also be that we are getting a virtual server while we're supposed to have a dedicated one, although we have no evidence that'd indicate this, except for the fact that the server tends to be quite slow. The server is Windows 2008 Standard 64-bit, with SQL 2008 Express Hardware is a Celeron 2.80 GHz, 1Gb RAM The website is developed in ASP.Net MVC, using Entity Framework for data access. Now, this is pretty crappy hardware, but i've had other servers with these guys, with equivalent (or worse) HW, and performance is much better than this one. That said, the other servers have W2003 and SQL2005, and I'm using ASP.Net "WebForms" 2.0, no MVC, no LINQ, no EF; so I'm not sure whether going to 2008 / the other stuff means a big performance penalty is expected. I'm serving MP3 files (5-20 Mb) regularly, which is a slightly unusual load, maybe that is causing some kind of problems? Would that cause w3wp to use a lot of CPU? Disk usage seems very low. Memory is usually around 90%, but disk usage seems to indicate it's not paging much. I get tons of e-mails every day about SQL timeouts, for queries taking over 30 seconds, although all our queries are pretty straightforward (or should be, but EF may be screwing it up). This is what resource monitor looks like in one of these "sprints" of 100% CPU, in case there's anything useful there. And a snapshot of some performance counters: Now, what confuses me very much is that CPU usage of w3wp is just so high. It shouldn't be doing much really... So my questions are... Is there any way of finding out "what" it is doing? Maybe even profile it? Any performance counters I should be looking at? Is this to be expected given this hardware/software configuration? Is this could be cause by some kind of configuration failure, where would you start looking? Thank you VERY much. Daniel Magliola

  • nginx not serving admin static files?

    - by toto_tico
    First, I want to clarify that this error is just for the admin static files. This means my problem is specific just to the static files that corresponds to the Django admin. The rest of the static files are working perfect. Basically my problem is that for some reason I cannot access those admin static files with the ngix server. It works perfect with the micro server of Django and the collect static is doing its job. This means it is putting the files on the expected place in the static folder. The urls are correct but I cannot even access the admin static files directly, but the others I can. So, for example, I am able to access this url (copying it in the browser): myserver.com:8080/static/css/base/base.css but i am not able to access this other url (copying it in the browser): myserver.com:8080/static/admin/css/admin.css I also tried to copy the admin/ directory structure into other_admin_directory_name/. Then I can access myserver.com:8080/static/other_admin_directory_name/css/admin.css Then, it works. So, I checked permissions and everything is fine. I tried to change ADMIN_MEDIA_PREFIX = '/static/admin/' to ADMIN_MEDIA_PREFIX = '/static/other_admin_directory_name/', it doesn't work. This a mistery in itself that I am exploring but still no luck. Finally, and it seems to be an important clue: I tried to copy the admin/ directory structure into admin_and_then_any_suffix/. Then I cannot access myserver.com:8080/static/admin_and_then_any_suffix//css/admin.css So, if the name of the directory starts with admin (for example administration or admin2) it doesn't work. * added thanks to sarnold observation ** the problem seems to be in the nginx configuration file /etc/nginx/sites-available/mysite location /static/admin { alias /home/vl3/.virtualenvs/vl3/lib/python2.7/site-packages/django/contrib/admin/media/; }

  • Is there a compression method for compressing a group of very similar files, without archiving them?

    - by awiebe
    I want to compress a large nuber of files that have near identical headers, and also some data, however I do not wish to archive them, nor do I wish to zip them individually(because the copression ratio would be much higher if substitutions of similar blocks could be done using a single table). Does a compression method exist to do this already, or should I implement it myself. Note: Don't say "Disk space is cheap", because I may want to use this on an embedded system.

  • Can't install .NET framework 4.0 on Windows XP professional version 2002 SP3 (OS bug?)

    - by that guy
    .NET framework 4.0 install fails on Windows XP professional version 2002 SP3: I tried to run setup using "run as..." to make sure the admin rights are used ("protect my computer..." tick was deselected of course). I tried everything: installing using online/offline setup, windows update. install goes a little and then "rolls back" and says: Installation did not succeed .NET Framework 4 has not been installed because: Fatal error during installation. for more information about this problem, see the log file. the full log: http://pastebay.net/1433771 Any ideas? EDIT1: I have found this in the log: "BlockIf: You must install the 32-bit Windows Imaging Component (WIC) before you run Setup. Please visit the Microsoft Download Center to install WIC, and then rerun Setup...." So I found it, and launched "wic_x86_enu.exe" - but it said: WIC Setup error Newer version of update is already on the system. I have already installed: .NET framewrok 2.0 SP2 .NET framewrok 3.0 SP2 .NET framewrok 3.5 SP1 but I need 4.0 . EDIT2: another attempt and it's log. (this time better copy of log file): http://pastebin.com/gmGfbM9a (copy to notepad and save as .htm and open with internet browser). I have tried all the solutions I could find - and nothing helped. I have found something weird: when I formatted the hard drive and installed windows xp again - the .NET framework 4.0 installed ok, but when I plugged my 100Mbit internet cable - the operating system kind off "locked itself" and the bug returned - I could no longer install .NET framework 4.0 again. There was no reason for that to happen, for example I have windows server 2003 in local network, but I don't have active directory enabled on it or anything like that - the server just has some folders shared and thats all (all server's "features" are default). I had the second pc with the same problem - with XP on it too. This seems like the bug of Operating System to me. I couldn't find what was causing the problem. After many days I gave up: backuped everything, formatted HDD and installed Windows 7 professional 64bit. .NET framework 4.0 installed with no problem on it.

  • NHibernate: Mapping different dynamic components based on a discriminator

    - by George Mauer
    My domain entities each have a set of "fixed" properties and a set of "dynamic" properties which can be added at runtime. I handle this by using NHibernate's dynamic-component functionality. public class Product { public virtual Guid Id { get; } public virtual string Name { get; set;} public virtual IDictionary DynamicComponents { get; } } Now I have the following situation public class Customer { public virtual Guid Id { get; } public virtual string Type { get; set;} public virtual IDictionary DynamicProperties { get; } } Where a CustomerType is something like "Online" or "InPerson". Furthermore an Online customer has dynamic properties "Name" and "IPAddress" and an InPerson Customer has dynamic properties "Name" and "Salesman". Which customer types are available and the extra properties on them are configured in meta-data which is used to generate hbm files on application start. I could figure out some way to knock this together using an intermediate DTO layer, but is there any support in NHibernate for this scenario? The only difficulty seems to be that all the different "types" of customer map to the same Customer class.

  • Centrally managing 100+ websites without bankrupting a small company

    - by palintropos
    I'm mainly interested in opinions on the trade-offs between having a single central server all the websites connect to as opposed to each website mirroring a subset of the master database with all the products in it. For example, will I run into severe performance issues (or even security issues, or restrictions) making queries to an offsite database? Will we hit scalability issues we can't handle early on from the sheer bandwidth required to maintain this? If we do go with something like a script that keeps smaller databases (each containing a subset of the central master data) in sync, what sorts of issues will we likely encounter there? I would really like the opinions of people far more knowledgeable than I am regarding the pros and cons of both setups and what headaches we are likely to encounter. CLARIFICATION: This should not be viewed as a question about whether we should implement one database vs multiple databases. This question has been answered numerous times. The question is regarding the pros and cons for a deployment like this having the ability to manage all the websites centrally (one server) vs trying to keep them all in sync if they each have their own db (multiple servers). REAL-WORLD EXAMPLE: We are a t-shirt company, and we have individual websites for our different kinds of t-shirts, but we're looking at a central order management integrated with our single shopping cart (which is ColdFusion + MySQL). Now, let's say we have a t-shirt that's on 10 of our websites and we change an image for it. Ideally we would change that in one place and the change would propagate, but how would we set this up?
