WPF Listbox and DataTables

Question

Hi all, 

 I am trying to bind data that's in my dataTable to a listbox with no luck. My datatable is in the business layer(I'm using 3-tier architecture) so I declare my BusinessLayer globally then when the user chooses something from a combobox I want items to be displayed in my listbox. The data in a listbox is not coming from a specific table in my database though, that is why I cannot set DisplayMember and ValueMember for my listbox. The data is just something like say SQL statement that :"select name,surname, From Patient Where Surburb = 'NewLands';" so this is not written to any table it gets retrieved when the stored procedure fires. I hope this clarifies things. So in my Business Layer I have a DataTable that uses the mentioned stored procedure and then on the code now I try to bind like this :

private void cboUnit_SelectedIndexChanged(object sender, RoutedEventArgs e)

        {

           lstUnassigned.ItemsSource = mdl.getUnassignedPatients().DefaultView;  

        }

where mdl is my business layer and getUnassignedPatients is a method that has the DataTable.

I get the following displayed as a result:

System.Data.DataRowView

 it displays this four times because the "table" I'm reading from has four values. So at least I know it reads the data but the problem is in displaying it. On my xaml I didn't set any binding etc to my listbox...

I'm pretty new to WPF  so this kind of problem throws me off since it's not even giving me a proper error.

Your help will be appreciated.
