Simple Question

Hi,

I'm fiddling around with VS Extensibility and am trying to interact with the WpfTextView.

I'm struggling slightly getting to grips with the new model. Basically all I want to do is change the selected text (equivalent to TextSelection.CharLeft(true,1); using the older TextSelection object). This should be a case of interacting with some aspect of my IWpfTextView object's Selection property. But I can't work out which. 

How do I do this with the new model?

I've 'inherited'  a website and although I'm happy with the .NET side of things I know very little about Javascript.  I've a simple validation function that isn't working.  I need to check that a date entered in a field is not after today.  The rest of the site is written in such away as to be culture aware and as such I don't have any hard coded date formats anywhere else.  Can I achieve this validation in JS without hard coding a date format?  Here's the code:

 function checkDate(src, args)
     {
         debugger
         var Received = document.getElementById('<%= txtTimeReceived.ClientID %>').value;
         var date_Received = new Date(Received);
         var currentTime = new Date();
            
     
       if (date_Received > currentTime )
       {      
           args.IsValid=false;
      

Someone help me with what I'm missing here...

I have a VERY simple file as you can see... just three tables.

The Problem is that if I do this somethign like this....

var patients = from x in db.CT_Patients
                     where x.CT_Visits...... (error here)

It doesn't display child properties for CT_Visits from CT_Patient like it should. I only get the standard LINQ queries like Select, Where, Orderby etc... What am I missing???

Thanks

I am using this book http://www.wrox.com/WileyCDA/WroxTitle/Professional-ASP-NET-MVC-2.productCd-0470643188.html
I discuss with author Project call NerDinner

there is 2 table Dinners and RVSP stored some information

author tries to retrive information from Dinners table with this function whic is written in Model Folder Class DinnerRepository:
here is:

public class DinnerRepository {

      private NerdDinnerEntities entities=new NerdDinnerEntities();

      public IQueryable<Dinner> FindUpcomingDinners() {
          return from dinner in entities.Dinners
                     select dinner;
        }
}

 public class DinnersController : Controller {
    
         DinnerRepository dinnerRepository= new DinnerRepository();

         public ActionResult Index() {
            var dinners = dinnerRepository.FindUpcomingDinners().ToList();
            return View("Index", dinners);
        }
 }

when I run this solution there is an error: The model item passed into the dictionary is of type 
'System.Collections.Generic.List`1[NerDinner.Models.Dinner]', but this 
dictionary requires a model item of type
