GridView won't refresh when ItemsSource is changed

[Sean]

I have to change the ITemsSource for a gridview when the tab index of a tab item changes, but it is not working.

  index = index - 1;
                            Object g = tcDates.SelectedItem;
                            TabItem ti = (TabItem)g;
                            DateTime selDate = Convert.ToDateTime(ti.Header.ToString());

                            this.dgvProcs.ItemsSource = null;


                            IList<Procs> currentList = this.apptProcsVerifs[index].Appointment;
                            this.dgvProcs.ItemsSource = currentList;
                            this.dgvProcs.Rebind();




here is the model:

public class VerificationApptModel
    {
     public event PropertyChangedEventHandler PropertyChanged;
     private object selectedItem;
     private IList<Procs> _Appt;
     private int _VerificationId;
     private DateTime _ApptDate;


     public VerificationApptModel(int verificationID, DateTime apptDate)
     {
         this.VerificationId = verificationID;
         this.ApptDate = apptDate;


     }



     public IList<Procs> Appointment
    {
        get { return _Appt; }
        set {
            if (_Appt != value)
            {
                _Appt = value;
                OnPropertyChanged(" Appointment");
            }
            }
    }

     public int VerificationId
     {
         get { return _VerificationId; }
         set {
             if (value != _VerificationId)
             {
                 _VerificationId = value;
                 OnPropertyChanged("VerificationId");
             }
         }
     }

     public DateTime ApptDate
     {
         get { return _ApptDate; }
         set {
             if (value != _ApptDate)
             {
                 _ApptDate = value;
                 OnPropertyChanged("ApptDate");
             }
         }
     }

     protected virtual void OnPropertyChanged(PropertyChangedEventArgs args)
     {
         PropertyChangedEventHandler handler = this.PropertyChanged;
         if (handler != null)
         {
             handler(this, args);
         }
     }

     public object SelectedItem
     {
         get { return this.selectedItem; }
         set
         {
             if (value != this.selectedItem)
             {
                 this.selectedItem = value;
                 this.OnPropertyChanged("SelectedItem");
             }
         }
     }

     private void OnPropertyChanged(string propertyName)
     {
         this.OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
     }

    }

 

I'm really stuck.. Please help deadline approaching

Hi Sean,

In order to suggest any further, I would need some more details. Do you want to have a single instance of RadGridView and reuse it on different tabs ? What is the exact scenario that you want to accomplish? Do you get any errors ?
