• How to integrate "basic" website into Zend Framework

  - by Joel

  Hi guys, I have a website that has around 10 pages. Only one of those pages uses Zend (to integrate with Google gData). Right now, it's just all coded into that one page, but I'm wanting to learn how to use Zend Framework. How do you handle basic-relatively static php pages within Zend Framework? Do you just stick the whole individual pages into their own respective views and then have to common stuff in the layout, and not worry about a model and controller for those pages? in general, is MVC accepted and appropriate technology for general "web-design" work?

• Is it possible to use Data Annotations to validate parameters passed to an Action method of a Contro

  - by dannie.f

  I am using Data Annotations to validate my Model in ASP.NET MVC. This works well for action methods that has complex parameters e.g, public class Params { [Required] string Param1 {get; set;} [StringLength(50)] string Param2 {get; set;} } ActionResult MyAction(Params params) { If(ModeState.IsValid) { // Do Something } } What if I want to pass a single string to an Action Method (like below). Is there a way to use Data Annotations or will I have to wrap the string into a class? ActionResult MyAction(string param1, string param2) { If(ModeState.IsValid) { // Do Something } }

• Is possible to set generic type by another class?

  - by Soul_Master

  I use ASP.NET MVC for serving web application and I want to create something like the following code. <% using(HTML.Form(Model)) { %> <% HTML.CreateTextBox('txt1', x => x.Property1); <% } From the above code, Form extension method will receive object that represent type of current Model object in current View page. Next, CreateTextBox method will receive type from Form method and I can bind textbox to some property of this model. Update 1 The following code is code of CreateTextBox method that will create instance of TextBox class. public static CreateTextBox(string value, Expression<Func<object>> bindedProperty) { // T should be receive from HTML.Form method or class return new TextBox<T>(value); } Is it possible to creating some code that doing something like the above code? Thanks,

• Field annotated multiple times by the same attribute

  - by Jaroslaw Waliszko

  For my ASP.NET MVC application I've created custom validation attribute, and indicated that more than one instance of it can be specified for a single field or property: [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true)] public sealed class SomeAttribute: ValidationAttribute I've created validator for such an attribute: public class SomeValidator : DataAnnotationsModelValidator<SomeAttribute> and wire up this in the Application_Start of Global.asax DataAnnotationsModelValidatorProvider.RegisterAdapter( typeof (SomeAttribute), typeof (SomeValidator)); Finally, if I use my attribute in the desired way: [SomeAttribute(...)] //first [SomeAttribute(...)] //second public string SomeField { get; set; } when validation is executed by the framework, only first attribute instance is invoked. Second one seems to be dead. I've noticed that during each request only single validator instance is created (for the first annotation). How to solve this problem and fire all attributes?

• Understanding configuration for parallel calling in web app (IIS + MS SQL)

  - by mmcteam.com.ua

  We have an ASP.NET MVC application + IIS 7.5 + SQL Server 2008 R2. We have to load a lot of aggregate counters on the each page. We decided to use ajax and call with javascript for each counter or groups of counters and return them as JSON result. We solve the problem that user doesn't wait for page loading, page loads fast. User waits for counters loading while seeing other page content. But we thought that if we make calls from javascript - our queries will be make async, but we notice, that it is not. All our javascipt calls runs immediately, but action that they invoke are in queue. If we use Async Controller ability - all counters calculating simultaneously, but user has to wait for the longest counter calculating before page loads. The question: We want to understand what is happens if we use ajax and call two or more actions simultaneously. And how can we configuring this. (also in each action we make some queries to sql server)

• CSS file not getting downloaded in Visual Studio 2008 SP?

  - by theraneman

  Hi guys, This might sound a little wierd, but all of a sudden the CSS and Javascript files referenced in my master page are not being downloaded while the page is being rendered. I am working on a ASP.NET MVC project and things were all fine like half an hour ago! Here is what I have in head section of the master page, <link href="/Content/MyCSS.css" rel="stylesheet" type="text/css" /> <script src="/Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> I can see the CSS class intellisense while designing pages. But in the page source I do not see these files being added. I can see the css being applied in the VS designer. I have tried restarting VS, restarting my machine too. Anyone else faced this situation before. I might go crazy now.

• Point IIS at debug folder

  - by mtmurdock

  I am working on an asp.net mvc web service and an Android app that need to be able to communicate with one another. However, when running a web service/web site in Visual Studio it can only be accessed by that machine. So what I want to do is point IIS at my project's bin/debug folder, thus exposing my dev environment to my local network. I know this is possible because my work machine is set up this way, I just don't know how it is done. How do I configure IIS to load a web app from the debug directory of my Visual Studio project?

• update portlet without refreshing portal page

  - by mike

  I'm trying to create a simple agena portlet. Now I've developed a basic one using spring-portlet-mvc, it allows you to navigate to the next and previous month with thusly named links that invoke a previousMonth or nextMonth function in my controller. Now the problem I'm having is that this navigation causes my whole page to refresh. Now I was wondering what the best way to fix this was. I've been looking around a bit and it looks like jquery/ajax will do the trick, but since I don't have any experience yet with that technology I was wondering if anyone had any pointers/better ideas to solve my problem.

• Do AOP violate layered architecture for enterprise apps?

  - by redzedi

  The question(as stated in the title) comes to me as recently i was looking at Spring MVC 3.1 with annotation support and also considering DDD for an upcoming project. In the new Spring any POJO with its business methods can be annotated to act as controller, all the concerns that i would have addressed within a Controller class can be expressed exclusively through the annotations. So, technically i can take any class and wire it to act as controller , the java code is free from any controller specific code, hence the java code could deal with things like checking security , starting txn etc. So will such a class belong to Presentation or Application layer ?? Taking that argument even further , we can pull out things like security, txn mgmt and express them through annotations , thus the java code is now that of the domain object. Will that mean we have fused together the 2 layers? Please clarify

• Which is the better way to avoid magic string keys? Using string const keys in a class or using enumeration?

  - by user596314

  My idea is to avoid magic string keys in my Asp.Net MVC application. To do so, I want to create string constant keys to be shared in the application. For example, I can write TempData[MyClass.Message] or TempData[MyEnum.Message.ToString()] instead of TempData["Message"]. public class MyClass { public const string Message = "Message"; } and public enum MyEnum { Message, Others } My questions are: Which is the better way to avoid magic string keys? Using string const keys in a class or using enumeration together with ToString()?

• LINQ to SQL DB Connections not closing

  - by Joe

  I am using LINQ to SQL in an asp.net mvc application. I am calling stored procedures via ajax calls. The active connections for 2-3 users goes to 100 active connections. and then server timeouts happen. I then used IOC -autofac to resuse the same repository that has a datacontext. now tho i get an active connection on the SQL server per loggedin user plus one. I have never seen this before. Why wouldnt Lin2sql not drop a connection when not in use? would calling a stored procedure in an ajax call in a loggedin session creat an a new active connection? Could a Stored Procedure with loops and or a waitfor hold open a connection??

• How can I convince IE to simply display application/json rather than offer to download it?

  - by Cheeso

  While debugging jQuery apps that use AJAX, I often have the need to see the json that is being returned by the service to the browser. So I'll drop the URL for the JSON data into the address bar. This is nice with ASPNET because in the event of a coding error, I Can see the ASPNET diagostic in the browser: But when the server-side code works correctly and actually returns JSON, IE prompts me to download it, so I can't see the response. Can I get IE to NOT do that, in other words, to just display it as if it were plain text? I know I could do this if I set the Content-Type header to be text/plain. But this is specifically an the context of an ASPNET MVC app, which sets the response automagically when I use JsonResult on one of my action methods. Also I kinda want to keep the appropriate content-type, and not change it just to support debugging efforts.

• Authenticating model - best practices

  - by zerkms

  I come into ASP.NET from php so the reason why i ask my question is because it's totally different nature of how application works and handles requests. well, i have an exists table with user creditians, such as: id, login, password (sha hashed), email, phone, room i have built custom membership provider so it can handle my own database authentication schema. and now i'm confused, because User.Identity.Name contains only user's login, but not the complete object (i'm using linq2sql to communicate with database and i need in it's User object to work). at php applications i just store user object at some static method at Auth class (or some another), but here at ASP.NET MVC i cannot do this, because static member is shared across all requests and permanent, and not lives within only current request (as it was at php). so my question is: how and where should i retrieve and store linq2sql user object to work with it within current and only current request? (after request processed successfully i expect it will be disposed from memory and on next request will be created again). or i'm following totally wrong way?

• Using "Go To Controller" and "Go To View" in Visual Studio 2008 when controllers are in different as

  - by ElvisLives

  The title is basically the question. We decided to move our controller classes to a separate library and reference it in our asp.net mvc 2 application. It works just fine when running the application, meaning the controllers are being referenced while the application is running. But when doing development (in Visual Studio 2008) and I am in a View and try to use the context menu "Go To Controller" it can't find our controllers in the new assembly. Same with when I am inside a controller, I don't have the Context menu to "Add View" or "Go To View" anymore. Does anyone one know how to remedy this? I searched like crazy but haven't found any solutions or even half solutions. Thanks!

• Can I use breakpoints (as while debugging) while 'unit testing' ?

  - by Richard77

  Hello, I'm walking through the FrontStore series tutorial on TDD in MVC (Part 3 by Rob Conery/ASP.NET). The test I'm concerned with is the CatalogRepository_Each_Category_Contains_5_Products(). Until I get to that test, everything was working fine. Now, I've gone through every line that makes this test (including the test itself, the TestCatalogRepository, ...). I've also compared my code to that of Rob, but the test keeps failing. I also checked the source code from CodePlex, that test was not there. Now, I wonder if I can put a break point somewhere to check the local values as the test is being executed? If not, something similar? Thanks for helping.

• @Html.Label won't allow string concatination

  - by MrGrigg

  I'm building dynamic forms based on a partial view. My view inherits a model with a single property: CatalogName { get; set; }. I have tried this: @Html.Label(Model.CatalogName + "-ProductNumber", "Product Number") @Html.TextBox(Model.CatalogName + "-ProductNumber") The HTML renders like this though: <label for>Product Number</label> <input name="CatatalogName-ProductNumber" type="text" /> If I write my code like this: @Html.Label("ProductNumber-" + Model.CatalogName", "Product Number") It will render the way I expect <label for="ProductNumber-CatalogName">Product Number</label> Is this a bug with MVC? Are there any answers to why my concatenation won't work the way I want it in the label, but works fine with the TextBox?

• form data posted using linq-to-sql not showing until I refresh the page

  - by PeteShack

  I have an asp.net mvc app with a form. When you submit the form, it adds records to the sql database with linq-to-sql. After adding the records, the controller displays the form again, and should show those new values on the form. But, when it displays the form, the values are blank, until you refresh the page. While tracing through the code, I can see the records being added to the database when they are submitted, but the view doesnt display them, unless I refresh. The view is not the problem, it just displays the view model, which is missing the new records immediately after the post. I know this is kind of vague, but wasnt sure what parts of code to include here. Could this have something to do with data context life cycle? Basically, there is a data context created when the form is posted, then a different data context is created in the method that displays the form. Any suggestions on what might be causing this?

• Creating a page selector with JSP/JSTL

  - by zakSyed

  I am working on a project where I am required to build a page somewhat similar to the one you see when you visit a website like blockbuster. When you click on browse more you are taken to a page with a bar on top with different page numbers and a drop down to select the number of pages you want to view on that page. I want to include a feature like that on my page but I am not sure where to start. In my page I have list of 200 items which I want to display page by page. I was suggested to use custom tags, but is there a more simpler or efficient way to create that functionality. My web application uses Spring MVC framework and is coded entirely in Java. Any suggestions will be appreciated.

• Generate form based on selection

  - by Jay

  I'm looking to build a web application that allows a person to select a plan and fill out an application for that plan. There are multiple plans and each plan generates a different application. Some of the questions are identical such as fields related to personal information. I'm thinking of using ASP.NET MVC to build this web application. When generating the multi page application would it be best to Create partial views (sections of applications) and combine them when generating the form. OR Build some type of dynamic form generator

• javascript "window.history.forward(1);" not working.

  - by Ray L.

  Hi, I'm trying to prevent the back button from working on one of my asp.net mvc pages. I've read a couple of places that if i put "window.history.forward(1);" in my page it will prevent the back button from working on a given page. This is what I did in my page: <script type="text/javascript"> $(document).ready(function () { window.history.forward(1); }); </script> It doesn't seem to be working. Am I using this incorrectly or is this approach wrong? thanks.

• Restrict confirm message on page reload with f5

  - by Max

  In my JSP page I am using post method while submitting the page. So once I go from Page 1 to page 2. In Page 2, If I press F5 I am getting alert as "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." I knew this question is a bit sarcastic but please give me an Idea. I can't change my method from POST to GET because I need to send large amount of data. Thanks in advance... Edited: In my Page1.JSP I call onClick function in that function I call action as "/page2servlet.do". Now, In Java side I use Spring Framework. With MVC Object I return to page2.jsp. So where do the response.sendRedirect Fit.
