Briefly

I'm creating a social site in MVC5..... I've a model User where i have some of these properties fname,lname,username,email,isNew...etc

so i've set isNew to false and when i press Login Button i've a if condition:

if(isNew==true) than redirect...to Index(A.M) Home(C) ....

else redirect....to NewUser(A.M) Steps(C)...

Now when i clicked Login Button its works pretty good i mean it redirect me to Steps(Controller) NewUser(ActionMethod) now here i want to set isNew value to true but i've no idea how to do this

This is what i have tried...

public ActionResult NewUser(User model) {

using (DbAccess db=new DbAccess()) {

var original=db.users.Find(model.uid);

original.isNew = true;

//var entry = db.Entry(original);

//entry.Property(e => e.isNew).IsModified = true;

db.SaveChanges(); } return Content("Welcome"); }

i'm new to Mvc/EntityFramework/Linq so no idea how to update this bool value...

You already have User model object coming as parameter you can attach it with context and update it like:
publicActionResultNewUser(Usermodel)
{
model.isNew=true;
using(DbAccessdb=newDbAccess())
{
db.users.Attach(model);
DbContext.Entry(model).State=EntityState.Modified;
db.SaveChanges();
}
returnContent("Welcome");
}

Hi,
Add the following line and try.
varoriginal=db.users.Find(model.uid);
original.isNew=true;
db.Entry(original).State=System.Data.Entity.EntityState.Modified;
db.SaveChanges();
