I was working on migrating MVC1 app to MVC2 today and i have come across a problem while changing the ValidationMessage to ValidationMessageFor implementation.
[Code]....
Is this somewhat a bug in "ValidationMessageFor"
I've successfully upgraded an web application from MVC1 to MVC2 but was wondering why the Binding redirect is required.I started have troubles with rendering views when it was removed ( strongly typed views switched model type to object ), despite have no more references to the original system.web.mvc in any project
View 8 RepliesI'm using ASP.NET MVC 3 right now with unobtrusive jquery client validation. By default, ValidationMessageFor generates a span tag with certain classes and attributes set. I would like it to generate a different template instead. For example, I might want a div tag with a certain background image.Is this possible at all, or can I just obtain the plain text error message from there so I can do my own styling?
View 1 RepliesI'm using DataAnnotations in my viewmodel class:
[Code]....
In my view I enabled client-side validation.
[Code]....
So, is this the way it's supposed to work? Shouldn't enabling client-side validation highlight non-validating elements by default, without an needing to create an associated Html.ValidationMessageFor(), if it has a DataAnnotation validation attribute?
I am looking on Music store example:
In Model we have:
[Required(ErrorMessage = "An Album Title is required")]
public string Title { get; set; }
In a View we have a Razor code:
<div class="editor-field">
@Html.EditorFor(model => model.Title)
@Html.ValidationMessageFor(model => model.Title)
</div>
My questions: Where I can find definition of EditorFor and ValidationMessageFor helpers?
What is the meaning of "=>" in the above command?
Let's say I have a property and a textbox on a view
[Code]....
I don't understand why each time I use the modelbinding validation like this
[Code]....
I still get the error displayed, But this time only by Html.ValidateSummary(). the textbox is not highlighted anymore and Html.ValidateMessageFor() doesn't display any message at all.
Is there something I should do the solve this problem? It's important because I have many form that user need to fill out. It's important to highlight the textbox to make it obvious to them.
found a way to get their validation messages to show as a tooltip instead of inline WITHOUT reinventing all validation framework over again?
View 6 RepliesI would like to use DataAnnotations in my ASP.NET MVC application. I have strongly typed resources class and would like to define in my view models:
[DisplayName(CTRes.UserName)]
string Username;
CTRes is my resource, automatically generated class. Above definition is not allowed. Are there any other solutions?
I have a simple model and view-model:
[Code]....
The view is strongly typed on AddressViewModel, and renders html elements using the xxxFor() helper methods, e.g.:
[Code]....
The html elements' names get prefixed by Address, so the name of the text element for the city ends up "Address.City" and the select element for the state ends up "Address.StateId".
I then added validation (a'la NerdDinner) - when the Address detects there is something wrong with the City it throws an exception and the controller retrieves the violations from the Address, e.g.
[Code]....
The problem (I think) is that ValidationMessageFor() looks for an error for a property "Address.City", however the error was added using the property name "City".
How does one deal with this problem - the problem being that the property name in html ends up not the simple property name that the validation logic used?
[Code]....
The model has a required attribute for the first name property:but I would like to make this happen automatically if the property has the CustomRequiredAttribute. Is there a way to override the Html.TextBoxFor() and check for the attribute on the given property? Or is there another way to accomplish this behaviour?
I'm getting close to finishing a public-facing ASP.Net app and I'm starting to weigh deployment options. I'm an ASP.Net/SQLServer veteran but noob when it comes to Azure. I'm wondering how others have felt about the learning curve to effectively migrate a local dev ASP.Net/SQLServer apps into Azure cloud. More specifically:How steep is the learning curve towards understanding administration and programming concepts, and do you think it's worth the investment?What is Microsoft's support like if I have catastrophic problems from my cloud infrastructure and my live site is down? My expectation is a large price tag for a not-so-urgent SLA.Will my non-Azure ASP.Net app require significant modification and/or coupling to run in the Azure environment?
View 4 RepliesWe already have our vb.net project in asp.net1.1 framework now we are changing the framework to asp.net4.0.But we are facing more warnings like unused local variables and function need return statement.it exceeding maximum warnings because of these kind of issues.Is there any tool to remove unused local variables.
View 1 RepliesI have upgraded my web site from 2.0 to 3.5 using VS2008 (loaded the project and selected 'yes' to the upgrade prompt), then deployed to the Live server. On the test system the website runs fine, on the Live, it fails with 'Assembly binding' (System.Core, System.Web.Extensions, and more) errors. When I commented out all the failed assemblies (just to see what happens) I got the error: 'csc.exe' cannot be found. Can anyone tell me what is wrong? 1. Is my upgrade method wrong? 2. Is there another way to upgrade? 3. How can I tell why the assemblies fail to bind?

View 2 RepliesAfter migrating my app to .NET 4 it's not starting. When i'm trying to load it in browser it endlessly loading it and nothing else happening. There is no errors or timeouts, just loading.
View 2 RepliesWhat are the inherent risk of upgrading a website from the 2.0 framework to the 3.5 framework?
I know the features given to me in the upgrade, just curious if there are any known issues that may pop up when upgrading.
I.E. Function X used to behave this way, and now behaves a new way.
some automated tools to help in migrating classic ASP to ASP.NET I tried to install "ASP to ASP.NET 1.x Migration Assistant" from the link below but it encountered a problem during installation. Has anyone used it? Any other better tools? I know everything cannot be automated but I would imagine there are some tools out there. [URL]
View 6 RepliesWe are in design phase of a project whose goal is replatforming an ASP classic application to ASP.Net 4.0. The system needs to be entirely web based. There are several new requirements for the new system that make this a challenging project:
The system needs to be database independent. It must, at version 1.0, support MS SQL Server, Oracle, MySQL, Postgres and DB2. The system must be able to allow easy reporting from the database by third party reporting packages. The system must allow an administrative end user to create their own tables in the database through the web based interface. The system must allow an administrative end user to design/configure a user interface (web based) where they can select tables and fields in the system (either our system's core tables or their own custom tables created in #3) The system must allow an administrative end user to create and maintain relationships between these custom created tables, and also between these tables and our system's core tables. The system must allow an administrative end user to create business rules that will enforce validation, show/hide UI elements, block certain actions based on the identity of specific users, specific user groups or privileges.
Essentially it's a system that has some core ticket tracking functionality, but allows the end user to extend the interface, business rules and the database. Is this possible to build in a .Net, Web based environment? If so, what do you think the level of effort would be to get this done? We are currently a 6 person shop, with 2.5 full time developers.

View 2 RepliesI know very little, and even less about .dll's. I have a fairly simple albeit old, application that references a .dll that seems to do the logic for connecting to an access backend. I don't have the source code for the dll, but I don't see any code anywhere elese to sigify the dataconnections etc. When I move the application from an old IIS6 server .net 1.0, over to a newer IIS7 server with .net 2.0osmething, I errors out (see below). When I remove the reference to the dll, the login pages comes up okay but I just can't login. So, something is up with my DLL. What do I need to do?

You have a SQL Database with legacy data.
New functional requirements stipulate that what was once a one to many relationship is now a many to many relationship. The relationship comprises a simple lookup table
How does one manage the migration of data from the old structure to the new???
I have the following script which will move the data from/to the right tables:
[Code]....
What i'm wondering is, once i have run the script to copy the data across, do people recommend that the LegacyTable.LookUpPK_ID field be deleted permanently?
We have application have been written in Silverlight using MVVM pattern. We need to move some pages into ASP.NET.
View 1 Replieswe are currently investigating a migration of an application that doesn't meet company standards. The application is built using VB6 and Shape SQL/Access. The application has about 120 reports by storing Shape SQL strings in a database which the user can modify using a wizard. Shape sql is not allowed at this company. We have investigated plain SQL, Linq, Entity Framework as alternatives... but all result in more complex solutions.
Update: Shape SQL is an ADO command to get hierarchical datasets, for further info:

Recently I moved my developing environment (Visual Studio 2005) on Windows 7. I followed the steps for migrating from IIS6 to IIS7, but when I try to start debug my web project I receive the error message:
"Unable to start debugging on web server. Debugging failed because integrated Windows authentication is not enabled."
In my project's web.config I have
<httpModules><add
name="WindowsAuthentication"
type="System.Web.Security.WindowsAuthenticationModule"
/></httpModules>
What else should I do?
We have a few settings in our web application that can be user configured. As IIS exposes helpers for configuring "Connection Strings" and "Application Settings" we decided to take use this method of configuration.
Unfortunately this works by editing the Web.config file deployed in the web application. This means that a simple upgrade process of copying over the files from a newer web application release resets all configuration settings to the default.
Possible options:
When upgrading the webapp, backup the Web.config and restore it afterwards. This is not elegant and if the latest webapp defines new default-valued properties in the Web.config then this will break Write some admin-only configuration pages on the site and store the values in the DB. This puts the control back in our hands, but it will take work to write this and obviously has bootstrapping problems with connection strings.
