It appears that xVal fits more into a MVC model. Can it be used for traditional Web forms model?
I am currently considering MS Validation block and .NET validation framework. What other validation frameworks can I look into?
I am using ASP.NET MVC2 and to validate the forms i use xVal. It seems like the server side validation works fine, but the client side validation doesnt work or atleast doesn't show up.
The code i use looks like this:
<% using (Html.BeginForm()) {%>
div class="label"><label for="EmailAddress">Email Address</label></div>
<div class="field">
<%= Html.TextBox(Prefix + ".EmailAddress")%>
<%= Html.ValidationMessage(Prefix + ".EmailAddress")%>
</div>
<%}%>
<%= Html.ClientSideValidation<Customer>(Prefix)%>
When i remove the prefix it works fine. But when i remove it only the server side validation works.
Searching on xVal on this side i found this post that looks a bit like the same problem: [URL]
I am using xVal with NHibernate Validator and I have a hard time to validate the dates.
First, NHibernate does not have validation for Date/DateTime formatting (except Past and Future). Second, I tried xVal itself (not using NHibernate Validator) but still no chance. I need to validate the date values (let's say in a text box), to make sure it's a valid date. For instance, 13/01/2010 or 11/31/2010 are not valid dates.
I have tried creating new rules for NHibernate Validator by extending a new class, but it needs to be declared in the xVal client side too. I don't like to overwrite the existing scripts, if possible. I also used xval's [DataType(DataType.Date)] but it doesn't check if the date is valid!
I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this?
Below the code which should make the relation to the resourcefile en specify the error when the field is left empty.
[Property]
[Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")]
public virtual Double ShippingCost { get; set; }
I would like to start a debate on traditional repositories versus one built on the UnitOfWork pattern. In a traditional repository, we wrap inserts, updates and deletes in a transaction, but selects don't really need them. In addition, nhibernate configuration is typically done once per application due to BuildSessionFactory being rather expensive. We often have several repositories of this type (one per aggregate chain). We also need to have projected, ahead of time, exactly what kinds of queries we'll need in order to build the interfaces and concretes correctly. In a single UnitOfWork repository we have the ability to manage both the current session and transaction, perform several operations, and then commit any changes all at once. In such a repository we may opt to put our configuration in the constructor since (typically speaking) no more than one Action is called per request anyway, initializing it in the application doesn't seem like much of an overall gain in speed. I must admit, I'm very temped to use the UnitOfWork pattern, as the following code looks really nice to me:
Csharp Code:
using (IUnitOfWork worker = new UnitOfWork()){// session and transaction are now both set
// save changes to three itemsworker.SaveOrUpdate(item1);worker.SaveOrUpdate(item2);worker.SaveOrUpdate(item3);
// grab a fourth var item4 = worker.Criteria<Foo>().Add(Expression.Eq("title", title)).UniqueResult<Foo>();
// delete the fourthworker.Delete(item4);
// all pending operations are commited or rolled back as a single unit (if one fails, all are rolled back), and then disposed, along with the session}
My proposed UnitOfWork class is rather simple. It implements IDisposable where I use a try-catch-finally in Dispose() to attempt a tx.Commit(), doing a tx.Rollback on failure, and a cleaning everything up in the finally clause. It also exposes common things like SaveOrUpdate, Delete, GetAll, Get, and even a Critera<T>() for custom on-the-spot queries. So what are your thoughts on this? I'd really like to hear about your experience with this pattern.
I am using xVal in a ASP.NET MVC project. One of the forms has two buttons and i want to disable the client side validation when one of the buttons is clicked. Is there a way to conditionally disable client side validation in xVal?
View 2 RepliesWe have two projects. One is in MVC and the other is the traditional Asp.Net project. We are trying to share a common Master Page for both the projects. The Master page for the MVC project is already using a form tag with runat="server" attribute because it's using a traditional ASP.Net control for the navigation menu. The ContentPlaceHolder is outside this form.
UPDATE:
Found the answer here:
[URL]
<form
id="Form1"
runat="server">
.......
<asp:ContentPlaceHolder
ID="MainContent"
runat="server" />
</form>
i have been recently requested from a client to upgrade his static html web site (hosted from another provider) to a new asp.net mvc web application (hosted from my provider). The current home page rank is 3/10 and i woul not like to lose it ehwn transferring the hosting DNS to another hosting provider company.
Is it possible to keep the home page rank? I am realy not interested in all the other pages.
Also, my home page can be accessed via [URL] disadvantage when comes to SEO?
Does [HandleError] attribute in MVC replaces the traditional try catch exception handling?
As I have seen codes in controllers where the top line of code is [HandleError] also I have not seen much of try catch in the code of the application I am working on.
How do you secure a WCF web service when you are using the traditional "connection string in the web.config"?
I have added a WCF service to an application which uses a JQuery post and returns JSON. The request happens on the client side. The purpose of this service is to return search information while the person is typing text into a textbox.
It works well, but there is a problem because the application will be used by a number of people and I am maintaining a role based security within the applications MS SQL database. The connection string to the database is in the web.config file.
In order to run the JQuery call to the web service the user must have at least read access directly to the database. I want to allow the application to control the access, but removing all security to the WCF service opens the application up for external access by unauthorized users.
I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.
When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?
Is it possible, inside a Custom Model Binder, to fire "something" that "says" the value is invalid so it gets handled by validation part?
Basically, I am getting an exception when the value for the property is invalid.
I made a few changes to the DB in SQL server management studio then right clicked on the .edmx doc to get it to update. That seemed to work fine but when i compiled the app everything that referenced the EF seems to be broken.The Error list now contains the below error for all classes that used it.
The type or namespace name '' could not be found (are you missing a using directive or an assembly reference?)
I have an issue of static variable in an asp.net application. Let's say I have a server with 8 CPUs running windows 2008 R2 hosting an asp.net webbsite, nothing fancy here, no funny configuration.
Is the following statement true? at any single time, there's one and only one process is running and accepting requests, even in the recycling stage. The reason I am asking is: I have a static field in my class, and I want to make that's the only static instance in the website. I've heard in some circumstances, IIS is recylcing your application, and it will start a new process, but the old process is still working, thus I will have 2 static instances in memory, which defeat the purpose of static field.
One step further, let's assume there might be 2 instances in memory, can I assume there are at most 2 instances at any single time? And can I assume once the second instance is up, the first instance will NEVER accept new requests?
Another question: Recently I have a problem with an applicationdomain concept. Looks like if an application domain causes a memory leak, unload the domain will not release the memory (Umanaged leak). So to what extent Application Domain is isolated?
I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted
<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>
This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });
This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }
But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.
when I use Html.HiddenFor( model => model.OwnerId ) to create a hidden field, the value assigned to that field is zero. When I use <input type="hidden" value="<%: Model.OwnerId %>" /> to add the hidden field to the form, the value is assigned correctly.
Why would Html.HiddenFor( model => model.OwnerId ) not get the correct value from the Model object? Am I supposed to load model state somehow separate from returning the model object from the action method? Here is the view:
[Code]....
The Create action method is relatively straight forward.
public ActionResult Create( ... )
{
ViewStockItem item = new ViewStockItem();
item.ActionCode = ActionCode.Add;
if (item.OwnerId == 0)
item.OwnerId = 7;
BookOwner owner = db.BookOwners.Single(c => c.OwnerId == item.OwnerId);
item.OwnerName = owner.OwnerName;
return View(item);
}
I've been used to decorating data model classes with data annotation attributes, but the purist in me baulks slightly at including purely presentational attributes such as display format here. I am, however, quite happy to keep validation centric attributes here. One good reason I have to continue keeping all annotations etc. in the data model is that my view model aggregates data model classes, e.g.
my ViewModelBase.DetailItem<TEntity> property in the view model is just a reference to an entity class in my data model. If I wanted to move presentational annotations to the view model, I would have to quite radically revise my design to one where I duplicate data model properties in my view model and use an object mapping tool to populate view model objects based on data model objects.
[code]....
Say I got a domain model as follows: (and my repository expect an instance of this object)
[Code]....
And a view model (which my views are based on)
[Code]....
At the moment I got it like this and have my controller action manually create a new Person object from the PersonModel object before passing it on to the repository, which does not feel right.
So I tried to have PersonModel inherit from Person and pass that to the repository (also tried casting the PersonModel to a Person object first), but that don't work out.
What's the right way to have PersonModel automatically cast to Person? I want to keep this logic as my current structure allow me to keep things really loosely coupled, with the repository layer not having a clue how it's being used.
I have recently started working on ASP.NET with MVC 2 framework, and I am facing following difficulty in validating my data,
Scenario:
In my application the view (ASPX) is divided into tabs (jQuery) and each tab's content is ViewUserControl (ASCX). The main model for the view has collection of sub models for individual tabs. I use RenderPartial method to render view user control.
[Code]....
And the user control (Tab1.ascx) refers the specific model for it,
[Code]....
Now if in my Tab1Model if I put following validation
[Code]....
In the controller ModelState.IsValid is always indicates TRUE. How do I override the validation behavior such that it as well looks the items in the collection member (which holds sub models) as well.
<%= Html.ValidationMessage("FirstName") %>
I am a newbie in mvc3 and i'm wondering how to use attribute like [Display(Name="")] for model that comes from an entity data model that I provide im my "Model" folder in my mvc3 project.
I didn't provide a .cs class for each of my database tables .

First Name:--- instead of : fName:---
I have been reading about different model for development
model view control mvc
model view presenter MVP
Model view view model MVVM
i belive MVC has two big Advantage over webform 1) TDD 2) More control on HTML
MVP is bit variation in mvc model. rapid development as well as 1) TDD 2) More control on HTML (correct me if i m wrong) see the below link
