Required attribute with resource definition uses wrong language

Hi all,I'm having a problem with a multilanguage application in MVC. On my model I'm using the following:[Required(ErrorMessageResourceType = typeof(VlanResources.Errors), ErrorMessageResourceName = "Common_NameRequired")] This takes care of validation... However the messages are always in the default language. Meaning that the setting of the culture of my thread is occuring too late (I'm currently setting it in my base controller 'OnActionExecuting'). Where could I patch in to change the culture accordingly before validation takes place?Thank you for your assistance,Ivan

Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.

Required columns on list; how can I reset them to be NOT required?

Viewmodel property not set to [Required] yet getting error message saying it is?


I have a viewmodel that i use for my view

public int SelectionId{ get; set; }        
public IEnumerable<Selections> Selections { get; set; }

Notice that SelectionId is not decorated with [Required]. In my view, i use DropDownFor like this:

<%= Html.DropDownListFor(m => m.SelectionId, new SelectList(Model.Selections, "Id", "Name"), "--- Select ---")%>

It should be possible to not select anything from the dropdown, resulting in model.SelectionId = 0, which is fine. Why do i get a "SelectionId field is required" error when i Post?  If i do this:

<%= Html.DropDownList(mySelectionId, new SelectList(Model.Selections, "Id", "Name"), "--- Select ---")%>

I no longer get the error if i dont select anything, which is what i want - but no way to bind it to the id if the user does select something

thanks for any help!

ReadOnly DateTime attribute stores correct date but only retrieves DateTime.MinValue on Delete


Hey everyone,

I have a dynamic data site that stores Event data using LINQ-to-SQL. When someone requests an event, it is first stored as a PendingEvent (which is a child of Event) with a column/attribute called receivedAt, which is [ReadOnly(true)] and which is assigned in InsertEvent as shown.

        partial void InsertEvent(Event instance)
            instance.requestedAt = DateTime.Now;




This works fine. The event displays with the correct receivedAt date, and it's correct in my database. It shows up just fine on my Display, Edit, and List pages. However, if I try to delete, the receivedAt in the instance (retrieved with my debugger) in my delete function is 01/01/0001 12:00am, also known as DateTime.MinValue. My other dates appear correct.

If I remove "ReadOnly(true)" from the received at, everything works fine. Why won't "ReadOnly" allow me to have a time?
Thanks in advance,



I forgot to mention why I care. I can't submit the instance to be deleted because DateTime.MinValue is outside SQL's available datetime, so I get a SQL error. The delete also takes place in a custom dele
