I am databind Listbox in MVVM pattern,I am using Entity Framework for getting data,this is how I am doing
XAML:
<ListBox Margin="0,26,860,-146" x:Name="lstuser" ItemsSource="{Binding ListBoxDS}"/>
C# code:
private ObservableCollection<Users> _lstusers;
public ObservableCollection<Users> ListBoxDS
{
get
{
if (_lstusers == null)
{
_lstusers = new ObservableCollection<Users>();
}
return _lstusers;
}
set
{
_lstusers = value;
NotifyOfPropertyChange("ListBoxDS");
}
}
public class Users
{
public int UserID { get; set; }
public string UserName { get; set; }
public string FirstName { get; set; }
}
DataContext:
public static IList<Users> GetAllUsers
{
try
{
using (var context = new ApplicationContext())
{
return context.UsersInfo.ToList();
}
}
finally
{
}
}
and in my ViewModel
var allusersList=GetAllUsers();
var users = allusersList.Where(a => a.FirstName =="some value").ToList();
foreach (var item in users)
{
_lstusers.Add(new Users { UserID = item.Id, UserName = item.Username,FirstName=item.firstname });
}
When I am ruuning my project,its not showing any item in Listbox, I am following this link I have debugged it, data is appearing in ListDS.
in your code i cant see that you add the item to your list. it should be
var users = allusersList.Where(a => a.FirstName =="some value").ToList();
foreach (var item in users)
{
ListBoxDS.Add(new Users { UserID = item.Id, UserName = item.Username,FirstName=item.firstname });
}
EDIT: then your code should work if you set the right DataContext. you can check this with Snoop at runtime.
