I cannot figure out why HeaderText or validation controls always fallback to default culture - even though rest of the controls are in correct culture.
I have a GridView with HeaderText specified in this way>
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
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.
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.
I'm using MVC 2.0 in an ASP.NET application using NHibernate. I have a working View, Controller and data access layer using NHibernate that is able to display and save an entity with a relationship to another mapped entity: Person -- > Location It's using the HTML helper HTML.DropDownListFor() to display a list of all Locations. The user is able to select one of the Locations from the list, and press save. The default model binder correctly sets the value of the Location on the Person entity being saved. This location is an nhibernate mapped entity, and is instantiated and has the id value that was selected in the dropdown list. Obviously, since the dropdown list that holds locations only has the ids of the locations, the rest of the values for the location are null. This is OK. I am only trying to save the Person with a reference to an existing location.
So, here comes the complication. We have a need to change the relationship between the two entities. Now the Person can have a reference to many locations. Person.Locations will be an IList My question is, how do you get the default model binder to take selections from a multiselect dropdown and populate an IList. I've managed to save collections of entities in the past using the syntax [index].PropertyName as explaing by Phil Haacked .... [URL]
The issue here is that I have only a dropdown list, and it will post back to the modelbinder a repeating key with different values:
This, unfortunately, doesn't work. the Location list keeps coming back Null. Our UI guy is using a slick JQuery pluggin to display the items in the select list, so I'd rather not have to use a different UI.
I saw a post with posibble problems with Model Binding which is mentioned here. [URL]. Whats the best approach to this? Different approaches are below. [Code]....
I have a complex page with several forms on it. The page is divided into sections, and each section has a continue button on it. The page is bound to a pageViewModel, each section addresses a different set of properties on the model. The continue button makes an ajax call to the controller, and the model binder binds it appropriately to the appropriate sections of the model. The section is refreshed appropriately. Finally, I would like to have a save button at the bottom of the page that takes all the forms, and binds all of the forms to the model. The model, at this point has all of the properties filled out, and can be processed accordingly. Can I accomplish this by some ASP MVC magic?
I am new to ASP.NET MVC and using ASP.NET MVC 2 with XVal. I am not using DataAnnotationsModelValidatorProvider and instead using NHibernateValidatorNHibernateValidator attributes. I would like to know that, when failing to provide a value for a non nullable type, how can i override the vanilla messages.There are actually two scenarios for non nullable type with model binding failure
1) when the data the user entered isn't compatible with the data type (for example, typing in "abc" for an integer field). The default message for this is: "The value [AttemptedValue] is not valid for [Property]."
2) when the user did not enter any data for a field which is not nullable (for example, an integer field). The default message for this is: "A value is required."
I know that the [Required] validator from DataAnnotationsModelValidatorProvider is treated specially during model binding failures on non-nullable types, so that you're not stuck with the vanilla message 'A value is required.'.
Also The DefaultModelBinder uses [Required] attribute for the second scenario only.Since I am not using DataAnnotationsModelValidatorProvider, I can not use [Required].Bearing in mind that I am already doing all the attribute validation and other business rules validation in my domain layer using XVal , What are my options here?
- Allow the model binding validation errors to occur, and then ignore and remove them from ModelState in my action method and refill it with my custom validation errors?
- Derive a custom model binder from and defaultmodel binder and override the onModeUpdated method ignoring all the validation?
My MVC 2 app includes a simple file upload within in a strongly typed view and I am trying to figure out how to apply model validation to the file name. Is this possible? Is there better way to do file upload within an MVC app?
The salient parts of the (prototype) controller code are:
[Code]....
The Create view code was generated with VS2010 and then modified to support file upload and client side validation:
I have a viewmodel with a property of a model class type. I set some properties in the model class to be able to show it to the user but then when I make a post, the model gets validated. How to overcome this? I don't want to enforce the DataAnnotations contraint in this case....
public class TheViewModel { TheModel TheModel { get; set;} } [code]...
I use viewModels to communicate between my controller and my view. To get model validation, i use a partial class like this :
[MetadataType(typeof(EvaluationValidation))] public partial class Evaluation { public class EvaluationValidation { [DisplayName("Title of evaluation")]
The first user control in the view is just to validate the customer and get some more details about the customer. This control is having one text box (customer name) with the button. When the user clicks the button it should validate the customer name in the client side using data annotations of customer model. if validation success then it should use some bussiness logic to verify the customer and show the customer details on the form.
The 2nd user control in the view is to get the address of the customer by searching for the house no and the postcode. This control is having 2 text box with the button.
The first user control is based on the strongly typed customer entity
The 2nd user control is bsed on the strongly typed address entity
The view with both the user control is based on the strongly typed order entity.
The issue here is with the validation. I have the validation summary in the view and client sider validation is enabled. When i click the search button on the first user control the client validation starts and throws validation error messages because when i search for the customer at that point of time i will not have values to may of the customer related fields in the order view.
The same thing happen when i click the search button on the 2nd view. It will throw client side validation for other fields.
What i want to achive is that when the user click the search button on the user control 1 then the validation should happen only to the customer name field (both in client and server).
When the user click the search button on the 2 nd user control the the validation should happen only for houseno and the postcode both in client and the server.
When the user clicks the save button on the order view all the fields in the form even the controls usere input fields should get validated. How to achive this in mvc?
With my model, I have one view model using another as its base. In my case, BaseUserModel is inherited by CreateUserModel, in order to share common properties such as Username and Password. My CreateUserModel adds to that by having ConfirmPassword, Email, SecurityQuestion, etc.
My problem is, when using the ValidationSummary() Html helper, the validation is obviously in order of the properties in my model. Basically, because of the inheritance I have going on here, the errors are not in the correct order.
Is it possible to control when or how these validation rules are added to the list? The only attribute I'm using is Required.
I make use of validation with data annotations in my model classes. How do I make sure this annotations are not violated when I validate data in my business layer, before sending it to the DAL? I guess I don't want to define the validation rules in two places (model classes and in my BLL-classes)?
I'm starting with asp.net MVC 2. Very cool.I have been reading about the data annotations validation attributes that can be set on the view model properties.It's cool but I have a scenario where I need to determine at runtime whether one of the property is required or not.How can I achieve this ? I want to have client side validation enabled too.
i am currently working on an asp.net mvc (.net 3.5 sp1) web app, that uses data annotations and client side validation. I would like to have localization enabled, thus i have implemented a localization mechanism for enabling site visitors select the locale they prefer, by overriding the Execute() controller action and setting the CurrentCulture appropriately (i get the culture to change to from the URL route parameters).
I tried implementing my model validation messages localization with no success. What i did was adding two resource files undeer my model App_LocalResoorces folder (one for my locale greek language Validation.el.resx and one for the default english language Validation.el.resx) and set the appropriate file properties ("Access Modifier" to "Public", "Build Action" to "Embedded Resource","CustomTool" to "PublicResXFileCodeGenerator" and "Custom Tool Namespace" to "ModelLocalRes". Then i added a RequiredFieldPrompt" name-value to both the resource files.
Then i tried modify the required validation attribute on my model's name metadata like this:
[Code]....
The problem is that i cannot get the localization working, since the error message gets displayed always for the english default locale, no matter the locale selected from the site visitor.
I use FileHelpers to import data from excel sheet to classes and then put it in MSSQL. Can somebody tell me if there is there a way to do model validation data imported from excel files?
point out an example or tutorial online that shows where data validation is done in the viewmodelas against the model? i saw a number of posts where that method is recommended..i dont really agree with it but i would like to see how it would work out..
