Question

Anyone knows how to work well with Windows Phone 7 local Database? (new Mango release, 7.1)
I am trying to make a Database (local) to hold two tables, I managed to make both of them, but I can't see why I got one error when making a query for the ObservableCollection (linq object), says doesn't have any argunments, therefore I can't pass new data from the collection to the DB... -.-'''!

Answer 1

// Define the query to gather all of the amino items.
var aminoItemsInDB = from AminoItem amino in aminoDB.AminoItems
select amino;

// Execute the query and place the results into a collection.
AminoItems = new ObservableCollection<AminoItem>(aminoItemsInDB);<-- this gives me an error! the argument!

Error: 'System.Collections.ObjectModel.ObservableCollection<AminoBlocks.AminoItem>' does not contain a constructor that takes 1 arguments

Answer 2

ObservableCollection<Person> PersonsNew = new ObservableCollection<Person>();
AminoItems = new ObservableCollection<AminoItem>(aminoItemsInDB);

Answer 3

True using ObservableCollection<Person> PersonsNew = new ObservableCollection<Person>();

your using: person=new ObservableCollection<Person>();
