I have set up my buddy class with validators. However I only want the validators to fire of the associated fields are used in that particular screen. When I split them across 2 screens I find my validation doesn't work. How do I fix this? I have had to remove the validation from some properties in order to get it to work on one screen;See the class here;#region "Buddy class" for validation
View 3 RepliesI am walked by Scott Hanselman's book through how to create NerdDinner MVC application.To validate the entity type Dinner that is generated by Entity Data Model Wizard, he extended the entity Dinner first by using partial class trick and then made a buddy class to be associated with Dinner.
namespace NerdDinner.Models
{
[MetadataType(typeof(DinnerValidation))]
public partial class Dinner { }
public class DinnerValidation
{
Required(ErrorMessage = "Title is required")]
[StringLength(50, ErrorMessage = "Title may not be longer than 50 characters")]
public string Title { get; set; }
[Required(ErrorMessage = "Description is required")]
[code]...
I have found hints that MVC 2 recognises the 'buddy class' type of property metadata, where data annotation attributes are applied to a 'buddy' metadata class, and the MetadataType on the actual entity class points to that buddy class, as below. However, as below, it seems the only attribute that makes any difference to the rendered UI is DisplayName. Why are the other attributes like DataType, Required, and ReadOnly not working? I.e. why can I enter text in a read only field? Why do I not get an error when a required field is empty? Why does the DataType attribute have no apparent effect? Why does EditorForModel not include validation messages?
[MetadataType(typeof(CustomerMetadata))]
public partial class Customer
{
public class CustomerMetadata
{
[ScaffoldColumn(false)]
public object CustomerId { get; set; }
[DisplayName("CustomerNo.")]
[ReadOnly(true)]
[Required(AllowEmptyStrings = false, ErrorMessage = "Customer No. is required.")]
public object CustomerNo { get; set; }
}
}
I find behaviour the same whether I use an explicit LabelFor and TextBoxFor for each model property, or a single EditorForModel for the whole model.
I write a class inherited from ValidationAttribute such as
[//...]
public class MyValidation:ValidationAttribute
{
//...
}
but when I use MyValidation,and EnableClientValidation,I found that it would not create client script automatically .
I have a requirement like display message to all the users in Television screen. There may be more than two Screens in those screens messages may be various. How can we display message or reports in screens using asp.net with c#.
View 1 RepliesI use Linq to Sql (although this is equally applicable in Entity Framework) for my models, and I'm finding myself creating buddy classes for my models all the time. I find this time consuming and repetitive. Is there an easy way to automatically generate these buddy classes based on the models? Perhaps a visual studio macro?

Is there a way to disable request validation on an action without having to add the line <httpRuntime requestValidationMode="2.0"/> to Web.config? I'm currently posting XML to a controller action and get the "A potentially dangerous Request.Form value..." error. Is disabling request validation the only way to get the post to work, or is there some way I can intercept and encode the value that contains XML between the view and the controller action?
View 1 RepliesI am generating dynamic screens as user requests. Anybody having any idea on how would I try localizing text (localization) in xslt?
View 1 RepliesI am a .NET / C# back end guy. I am working on a app that will have about 200 different data entry screens. For me exposing DTO as a collection for CRUD (IUpdatable and IQueryable) is the easy part, I can do it in my sleep :-). What I am trying to decide is what type of front end technology will allow me to develop these data entry screens fast. They don't have to be fancy but they are not just plain grid either and on average they have about 15 form fields and some client side data validation (no db look up) Options I am looking at are
Use ExtJS on the front and REST / JSON on the back. ASP.NET RIA but I do not know SL (Well XAML) Plain ASP.NET / MVC One idea I had was the DTO will contain the meta data about the form (As Attributes) and the form can be dynamically generated, but I do not want to reinvent the wheel if there is an easier way. I have looked at RAD software but all of them look at the DB and generate screens. I'd rather want something that can look at my DTO and generate screens.

I have been playing with mvc for a few months now and one of the best things I thought was when there is validation errors the UPDATEMODEL method in controller is smart enough to automatically add errors to model state and return the view back to the input page with data entered and error message. Here is where I got a question - how does the controller put back the data that I entered initally? I looked for model, request and response object and none of them have the (invalid) data I entered. Here is an example of my general coding that I do:
[code]...
I have the following textbox with validation:
<asp:TextBox ID="txtInput" runat="server" Width="80px"
CausesValidation="True"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredValidator" runat="server"
ControlToValidate="txtInput"
Display="None"
ErrorMessage="Bitte füllen Sie dieses Feld aus"
Enabled="false" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator" runat="server"
ControlToValidate="txtInput"
ValidationExpression="[0-9]{1}(d)*"
Display="None"
ErrorMessage="Bitte geben Sie eine Zahl ein"
Enabled="false" />
<asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender1" runat="server"
TargetControlID="RequiredValidator" />
<asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender2" runat="server"
TargetControlID="RegularExpressionValidator" />
If I click on a button on this page (CausesValidation is set to true) then the control validates properly.
But when I put the textbox and its associated validators and extenders not directly on the page, but instead into a usercontrol then the validation-popup doesn't show anymore. It still seems to validate, because the action for the button is not triggered when the input is invalid.
I have an ASP.NET web app (with C#). In it I have a form with several fields and validators. For one of the validators I only need to validate when:
a certain textbox is empty and a certain record does not exist in the database (this is already handled).
I know I can't enable/disable the validator on page_load because something might be entered into that textbox. I also tried the following in the onclick event of the submit button but it didn't seem to work:
Validator1.Enabled = true;
Validator1.Validate();
I also tried Page.Validate() but that didn't work either...
I am inexperienced using classes so I'm sure I'm not doing things in a standard way. I have created a hierarchy: Deals,Deal, DealSlots, DealSlot that is represented by 4 corresponding vb files So I can reference like so in my aspx pages dim alldeals as class Deals some id=Deals.Deal(1).DealSlots(2).PersonID I created a Public Method GetDealData which is in Deals.vb and gets data from a database and attempts to populate the class variables.I have a test.aspx that uses this function like so:
[Code]....
I have 2 projects. A data project, which contains my database and my Entity Framework model. I have table called 'User', and then have a generated EF class for user. I am trying to add a partial class:
using System;
using System.Collections.Generic;
using System.Data.Linq;
using System.Linq;
using System.Text;
namespace Data
{
public partial class user
{
public bool isValid
{
get {
return (GetRuleViolations().Count()==0);
}
}
public IEnumerable<RuleViolation> GetRuleViolations()
{
yield break;
}
partialvoid OnValidate(ChangeAction action)
{
if (isValid)
throw new ApplicationException("Rule violation prevents saving");
}
}
public class RuleViolation
{
public string ErrorMessage { get; private set; }
public string PropertyName { get; private set; }
public RuleViolation (string errorMessage)
{
ErrorMessage = errorMessage;
}
public RuleViolation(string errorMessage, string propertyName)
{
ErrorMessage = errorMessage;
PropertyName = propertyName;
}
}
}
This is following the MVC 1.0 NerdDinner example. However, I am getting a design time error on the OnValidate method:
partial void OnValidate(ChangeAction action)
{
if (isValid)
throw new ApplicationException("Rule violation prevents saving");
}
No definining declaration found for implimenting declaration of partial method 'void OnValidate(ChangeAction action)' What am I doing wrong?
I don't know what the problem is a get the message object required??

I'm currently developping an application using MVC2 and Globalization (fr and de). I'm creating a form who use DataAnnotation on the model for validation, with localized error messages in my dataAnnotations.
Here is the trick :
I have two <input /> :
One for a required date (example : 12/05/2001) wich is a DateTime field in the model :
[Code]....
One for an optionnal hour (example : 22:30) wich is a DateTime? :
[Code]....
Erreur and LibellesSinistre are my ressources files.
I got two problems :
I can enter a date in my hour field and an hour in my date field.My error messages aren't localized.
Do I need a trick or something to make it work ?

View 1 RepliesI am trying to implement the TinyMCE Spellcheck plugin that uses GoogleSpell. The thing is I am trying to install it in an MVC environment. I started by referencing the .NET class Library DLL (MoxieCode.TinyMCE) in my project. Then, I added this code to my web.config:
<system.webServer>
<handlers>
<add name="TinyMCE" verb="GET,HEAD,POST" path="TinyMCE.ashx" type="Moxiecode.TinyMCE.Web.HttpHandler,Moxiecode.TinyMCE" />
</handlers>
<!--previously existing rules-->
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
I then added these lines to my tinyMCE.init({}); call:
plugins: "spellchecker",
theme_advanced_buttons3: "spellchecker",
spellchecker_languages : "English=en",
spellchecker_rpc_url : "TinyMCE.ashx?module=SpellChecker",
These steps are outlined in the tutorial here. I then followed instructions from this stack overflow post which recommended the following modification to global.asax to make it mvc friendly:
routes.IgnoreRoute("TinyMCE.ashx");
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
Everything seems fine accept that when I browse to /TinyMCE.ashx i get this error:
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /TinyMCE.ashx
Why can't asp.net mvc process that url?

Using MVC 3 RTM and MvcContrib/FluentHtml version 3.0.51.0, I can't get the jQuery client side validation to work. Server side validation works fine, and returns showing the correct validation summary, etc. But the form post always tries to hit the server-side post controller action when it should have stopped on the client side to display the validation error.
I tried replacing the MvcContrib ModelViewPage with the default Mvc ViewPage and it still didn't work.
