Execute LINQ Query Using Properties Of Child Entity Set
Nov 25, 2010I am having a meltdown over something that seems so simple and yet isn't working. Here's my scenario.
I have an object structure of tEvents, which contains properties of an event like a run of concerts. tEvents in turn contains an entity set of tEventOptions, which include properties like EventDate, Cancelled etc. I would like to query a list of tEvents using properties of the tEventOptions, for example filtering by date.
My pageis using a calendar object to show event dates. So I am trying to find if any tEvents in the List coming back from the database match the date of the day element being rendered in my Calendar control like so (in this snip 'data' is List and results from a db query):
[code]....
Except r, my query result var, is always true no matter what data it receives. I have tried the sub query using other properties of tEventOption and get the same 'true' result each time. I know that the data does not reflect this result so I clearly have a problem with the structure of my query, but for the life of me I cannot find a way to resolve it.

MVC :: Selectlists And Nullable Properties
Jan 25, 2010I have a ASP.NET MVC view that displays a single ServiceProvider object. In this view there is a selectlist that lists one or more ServiceProviderGroup objects and uses the Id property for the value and the Name property for the text. In this list I also show a entry with a value of -1 and text of "No Provider". When the Edit[Post] method is called the Id value from the select list maps to a nullable property (GroupId) on a ServiceProvider object. When a value other the -1 is selected from the list it works as expected. But, when the value is -1, I want a NULL reference to be applied to the GroupId property during the UpdateModel call. Within the Edit method, prior to calling UpdateModel, I have tried replacing the entry within the Controller.ValueProvider with a null reference and adding a ValueProviderResult which contains a null reference, but the UpdateModel always has an issue (InvalidOperationException).

That is true, it's not a property, it's a public field

How can I databind to these fields since they are not implemented as properties? Any suggestions? I'd like to avoid writing wrapper objects with property implementations if at all possible.
