In my project I use Strong Types Views. Because I find it nice structured.
public abstract class AbstractViewData: View Page ( ICollection Foo; )
public class HTML Component View Data: AbstractViewData ( string Foo2; )
I have the same structure in my code, as in the corresponding pages.And here starts the problems. I would like to use HTML.Display (o => o.Foo) could be a customer for that matter.But my Strong Types Views have not posted Metadata Model into my classes.Like: Return View ( "FooView", customer); would.Is there a way to write some code that can solve this problem for me?
My case:I am developing an application that will run for multiple clients, each client has the ability to customize field displays and error messages.My issue:I created some custom attributes which inherit from DisplayNameAttribute, RequiredAttribute etc... and in them I am pulling out the resource needed.However it is only executed the once, so if my context changes it will be pulling the incorrectly cached value instead of pulling the new value need.Has anybody attempted to try something like this with the data annotations? Or any advice such as just don't use them for this scenario?
I'm working on an ASP.NET MVC 2 project with some business entities that have metadata dataannotations attributes applied to them (Validation attributes, Display attributes, etc.).
Something like:
[Code]....
Using the metadata from different views is no problem, as long as I am using my business entities as viewmodels or as part of a viewmodel like this:
[Code]....
However, sometimes I need to code a view for editing some, but not all fields of an entity. For those fields I want to reuse the metadata already specified in my user entity. The other fields should be ignored. I'm talking about custom view models like this:
[Code]....
That's where I am running into problems. The custom view model above leads to an exception when the view is generated, because it has no password property.
The associated metadata type for type 'Zeiterfassung.Models.ViewModels.Users.UserNameViewModel+UserModel' contains the following unknown properties or fields: Password. make sure that the names of these members match the names of the properties on the main type.
Also, even if this exception did not occur, I expect to get into even more trouble with model validation on form submit because Password is marked as required in my business entity.
I can think of several workarounds, but none seem really ideal. In any case I can't change the database layout so that the password field would be in a separate entity in my example above.
i am working an asp.net mvc 2 web app using model metadata and some of the model metadata don't seem to work when using the default Html.EditorForModel().For example, when applying the DefaultValue(1) and the ReadOnly(true) attributes on a model field, the field displayed on edit view has zero for its default value and it is not read only.
I would like to separate my attribute decoration(3-4 per field) by having them someplace else so that my code looks readable.Also the arguments passed to some attributes should come from a resource file.EG:[Required("Cannot proceed without entering *field_Name*")]
I need just [Required] Possible duplicate of this question(on which i couldn't resist offering a bounty) : Default resource for data annotations.
I was wondering if anyone can point me in the right direction? I have a POCO model and I am using Code First CTP. In my application, I set the database to be recreated whenever the model changes.
I would like to write custom functionality to access the model (POCO) metadata same way as EF sees it and use that to generate some source files (using T4). I would like to access the processed model not having to worry about finding properties that hold primary keys or any other conventions (implicit or not). What is the way to go about it?
I need to create different page views for different types of users. I already asked that here: How to create pages with different permissions' views And even though Aldeel's answer works, it does not seem the best solution for me. I'll explain why. I need to show different views but it's not only like that. Each user can have access to different parts of the page.
Imagine a page 'X' with this structure
Field A Field B Field C Field D
When user U1 from group G1 visit page X the system checks the DB for that group's permission on page X. User U1 can see Field A and Field B, but only edit Field A. User U2 that is set to no group visits page X. The system checks for his permissions on page X. User U2 can see and edit all fields. When user U3 from group G2 visit page X the system checks the DB for that group's permission on page X. User U3 can see Field C and Field D, but can not edit any.
I coudn't find a way to do that instead of filling ViewData with lots of data about that specific user's permission. In my example there are only 4 fields, but in my current project I have no screen with less than 20 fields. So I guess you can see how ugly and not productive that is. The idea is similar to a social network, as I said (facebook example). When a user visiting UserX's page can only see what UserX has allowed him to.
I have 2 partial views and models for them. I want to show both views on page and i assume i need one model to pass to the page. Do i have to create all the properties again for both partial views into one model?
What I want to achieve is the ID of the property: item.Item.ID to be bound to the ID from the (route)URL. However I can't get it to work. I tried using [Bind()] attribute.
I fixed it now using a hidden field in the form like so:
<%= Html.HiddenFor(model => model.Item.ID)%>
However this feels a bit icky. I'd like to know if there is a better cleaner way of doing this?
When i loading modules from different places i injected them to controller factory, but when it is trying to load strongly typed views it can't find model type that is contained in module assembly.I made new ViewEngine and now it looks in right places but it cant load strongly typed views.
So as i understand i need to show the view where to find class model. If you have any other ideas please tel me. And one more i need this problem to be solved for WebFormViewEngine and RazorViewEngine.
I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")] [Title("Enter your 10 digit user id")] property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?
I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.
I am learning MultiView control.Here are question:I added 5 views in the MultiView but all views are tight together. I can not drag and drop another control such as text boxes or labels into view area.
My ASP.NET application is using an assembly without strong name. When I run it in IE, it shows an error saying: Could not load file or assemlby 'xxxxx.' or one of its dependencies. Strong name signatuer could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045)"I use sn.exe -Vr xxxx to register that assembly to skip the strong name verification, but still it shows that error. What could be causing this problem, and what can I do next to fix it?
1) Should be 6-15 characters in length 2) Should have atleast one lowercase character 3) Should have atleast one uppercase character 4) Should have atleast one number 5) Should have atleast one special character 6) Should not have spaces
Can anyone suggest me a RegEx for this requirement?
Today I had a problem with some routing in my ASP.NET MVC 3 application (with Visual Studio 2010).So I thought I install the ASP.NET RouteDebugger and fix my route problem. After I get the package through NuGet my project doesn't build anymore: referenced assembly ' RouteDebug' does not have a strong nameI could download the source of the RouteDebugger and build (and strongly sign) it myself, but that's not the purpose of NuGet isnt' it ;)
I thought about simulating strong-typing for key-value configuration of a new project by providing fake property info via implementing ICustomTypeDescriptor.The configuration instance should provide all default config keys as properties with default values however: I noticed that VS08 intellisense doesn't include "faked" properties which are created in example similar to [URL]
I have a web site project in which my architecture is n layered architecture.I am using Micorsoft Enterprise library's validation dll.As of now this dll is not strongly named. I need to make that assembly strongly named. how can i do this.I saw some articles which depicts how to create strong named assembly by taking the vs 2008 command promtp and type sn -k publickey.snk, and then add the assembly tag to the assemblyinfo.cs. I tried to do that, but my website project dosen't have any assemblyinfo.cs file.
I have an asmx file that was created using notepad. Then I created the proxy class using wsdl.exe. Now I have a dll that I want to put it in GAC. GAC needs the DLL to have a strong name. How can I create a strong name for the web service?
I would like to state literally that I really do not want to reinvent the wheel, but as you know some times we get some unique "Must-requirement(s)" that will hinder us to re-use the open source codes.I want a proper, flawless and consistent Web Crawler. Basically, I want this Crawler (As a Web app NOT desktop app - Of course based on asp.net and C#) to grab the pages of any website and store them locally (Including resources like images and CSS...etc), download them locally and adjust any resource hyperlinks to point to the locally downloaded resources.
I saw HTTrack (http://www.httrack.com/), and it seems quite excellent, but the problem is that I want this Crawler to be a part of a system which includes other features and process. So, I really can't have this Crawler as an external tool.Main challenges:1) User should be able to specify to which level s/he wants to crawl, which means: User might specify a sub-site and want to crawl everything underneath it and not the upper level. You see ? So, there should be full crawling for the entire site and partial crawling.
2) URLs and how to deal with them? I faced some weird URLs and it was hard for me to identify the actual page because there is no file name. How to handle that? For example: (http://www.blue1.com/en/uk/Travel-info/At-the-airport/Security-control/) this is a URL of a website that is built on EPiServer (.Net based) but as can be seen from the URL that there is not actual aspx page, Therefore, how to deal with such URLs ?I have already started developing a POC using HttpWebRequest class, but frankly I am totally dissatisfied with it. It is inconsistent and the generated static content misses a lot of images and styles. Besides, the threads act up sometimes strangely.I would greatly and sincerely appreciate any input (Approaches, source codes, ideas , links...etc)P.S. I already saw: (http://www.codeproject.com/KB/IP/Crawler.aspx) and (http://www.codeproject.com/KB/aspnet/ZetaWebSpider.aspx).
I have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller,
