Anyone created an overload for "ValidationMessageFor"?Basically I just want to override the Css Class Names. Looking at MVC3 Beta Sources I can see this is static readonly strings specified in System.Web.Mvc.HtmlHelper.
View 2 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 was working on migrating MVC1 app to MVC2 today and i have come across a problem while changing the ValidationMessage to ValidationMessageFor implementation.

Is this somewhat a bug in "ValidationMessageFor"
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:

I am keep having the "No overload for method 'GenerateSignature' takes 9 arguments" problem. what is wrong with this class.This code is the sample from the Oauth.net . I think it too old for my asp.net 3.5 or 4.0.

I use the class below in my code-behind to connect to my database. How would I (overload?) this class to choose between multiple connection strings (databases)?
Or should I have a separate class for each connection?

In a asp.net mvc form, im using a radiobutton set, to set a property.
<%=Html.RadioButton("Tipo", "Pizza",
CType(Model.Tipo = "Pizza", Boolean), New With {.id = "Pizza"})%>
<label for="Pizza">Tipo Pizza</label>
<%=Html.RadioButton("Tipo", "Barra",
CType(Model.Tipo = "Barra", Boolean), New With {.id = "Barra"})%>
<label for="Barra">Tipo Barra</label>
I need the CType or i get an overload error. This case seems like the most commom use of radiobutton when working with a Model property. Of course i could create a partial view or a control, but apart from that, is there a cleaner code to accomplish this?

After looking at about 200 examples on this and other sides, I combined several pieces of code that I found and created one to upload an image, give it a random name, verify that a file with that same names doesn't already exists on the server, resize the image 3 different ways; one keeping aspect ratio and two square thumbnails; and save them to different folders in the server.

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?

I do have a page that is literally overloaded with about 10 GridViews and there is a datasource for each particular one. Now, each GridView is hide inside a panel, so I only display one at a time depending on what is it that the user request. My concern is the followng: Even though I am only displaying one GridView at a time, do the others datasource are still working behind the scene on the blind side and therefore are putting a load on the server and on its performance. Or I do not have to worry about this because as long as the Panel.Visibility = False, nothing inside that panel is working.
