Question

I’m using Prism v4 , and MVVM.
In my viewmodel i have:

private TB_COMPANY tb;
    public TB_COMPANY Tb {
        get {
            return this.tb;
        }

        private set {
            if ( this.tb != value ) {
                this.tb = value;
                this.RaisePropertyChanged(() => this.Tb);
            }
        }
    }

In my Page, i have a datagrid (i tried with a listview too, don’t work!):

<DataGrid ItemsSource="{Binding Tb.TB_ADDRESS.RL_ADDRESS_PHONE}" .../>

RL_ADDRESS_PHONE is a list of phones of the company…
So, in some moment i add phone to the list:

private void MyCommand() 
{
    ...
    Tb.TB_ADDRESS.RL_ADDRESS_PHONE.Add(
        new RL_ADDRESS_PHONE
        {
            TB_PHONE = new TB_PHONE 
                       { 
                           NU_PHONE = _txtTelefone, 
                           ST_TYPE = _txtTipoTelefone 
                       }
         });
    ...
}

But nothing happens to the UI…
But in the Debug, the list is fullfiled….
What should i do to update the UI?

Answer 1

The RL_ADDRESS_PHONE property of TB_ADDRESS must implement INotifyPropertyChanged as well. If it is a List, you should use ObservableCollection which implements INotifyCollectionChanged which is necessary for the behaviour you are trying to achieve.

Also, as a piece of advise – have a look into the design guidelines and naming convention of the C# language, you can find it in the msdn (while it says .net 1.1, it still applies for any following versions of the framework).
