Und das ViewModel:
| C#-Code: |
using System.Linq;
using RAE.Client.Extensions;
using RAE.Client.Model;
using RAE.Client.Session;
using RAE.Data.Models;
using WpfBase;
namespace RAE.Client.ViewModel
{
public class ShowTaskOverviewViewModel:BaseWorkspaceViewModel
{
public ShowTaskOverviewViewModel(int windowId) : base(windowId)
{
if (DataManager.IsAdmin)
{
DataManager.Repository.GetAllEmployesCompleted += (s, e) =>
{
Persons = new ThreadSafeObservableCollection<Model.EmployeeModel>();
if(e.Employees != null)
e.Employees.ForEach(p => Persons.Add(p.ToModel()));
};
DataManager.Repository.GetAllEmployeesAsync();
}
else
{
DataManager.Repository.GetAllEmployesByEmployeeCompleted += (s, e) =>
{
Persons = new ThreadSafeObservableCollection<Model.EmployeeModel>();
if (e.Employees != null)
e.Employees.ForEach(p => Persons.Add(p.ToModel()));
};
DataManager.Repository.GetAllEmployeesByEmployeeAsync(DataManager.CurrentUser);
}
this.DisplayName = "Aufgabenübersicht";
Tasks = new ThreadSafeObservableCollection<RAETask>();
}
public ShowTaskOverviewViewModel(int windowId,Employee emp)
: base(windowId)
{
_persons = new ThreadSafeObservableCollection<Model.EmployeeModel>();
this.DisplayName = "Aufgabenübersicht";
}
private EmployeeModel _currentItem;
public EmployeeModel CurrentItem
{
get { return _currentItem; }
set { _currentItem = value;FillTaskForEmployee(); OnPropertyChanged(() => CurrentItem); }
}
private ThreadSafeObservableCollection<Model.EmployeeModel> _persons;
public ThreadSafeObservableCollection<Model.EmployeeModel> Persons
{
get { return _persons; }
set { _persons = value;OnPropertyChanged(() => Persons); }
}
private ThreadSafeObservableCollection<RAETask> _tasks;
public ThreadSafeObservableCollection<RAETask> Tasks
{
get { return _tasks; }
set { _tasks = value;OnPropertyChanged(() => Tasks); }
}
private void FillTaskForEmployee()
{
Tasks.Clear();
_currentItem.Tasks.ToList().ForEach(p => Tasks.Add(p));
OnPropertyChanged(() => Tasks);
}
}
}

Wenn ich auf eine Row klicke erscheinen zwar die RowDetails aber nur die Header.
Es werden keine Daten angezeigt. Die Namen der Propertys passen aber alle.
Sieht jmd auf den ersten Blick, wo der Fehler liegt ?
Grüße
