Windows Phone 8.1 How to search combobox list?

Question

I have a combobox list created by binding to an ObservableCollection<> read from a JSON file. The
ObservableCollection <T> source has two strings and I want to find the object within the combobox list that
matches the value of one of the strings.  I can do this using foreach but I wanted to know if there was a way e.g.  combobox.items.where(x => x.ItemId == "4").  This example returns an error so does that mean that combobox in 8.1
does not support .where and .select, etc. for searching ?

Hi,
Have a look at the below sample code 
var filter = Data.Where(dataItem => dataItem.ItemID.Equals("123"));
From your above error message, it says the property "ItemID" is not referred in a proper way.
For that to work, Your DataModel should be 
public class DataModel
private ObservableCollection<DataItem> Data { get; set; }
public DataModel()
Data=new ObservableCollection<DataItem>();
public class DataItem
public string ItemID { get; set; }
