Witam,
W między czasie pojawił się jeszcze jeden problem ze zrozumieniem tematu. Może ktoś by podpowiedział co jest źle ?
Mam taki kod opisany poniżej :
w pliku XAML (VIEW) mam coś takiego:

W pliku modelu mam tak:
```csharp

using Modbus;
using System.Threading.Tasks;

set { _mrs1 = value; OnPropertyChanged("MSR1"); }

}
public double MED2
{

set { _med2 = value; OnPropertyChanged("MED2"); }
}
#endregion
#region Constructor
public DaneModel()
{
MED1 = 0.00; MED2 = 0.00;
DataFromOther(2); // Pobiera dane dla MRS1 = wartość1; MRS2 = wartość2;
}
#endregion
private void DataFromOther(int licznik)
{
// pobranie danych z jakiegoś źródłą (nie baza danych)
}
}
}
</CODE>
W pliku ViewModel mam tak:

}
#endregion
}
}
</CODE>
// W parencie (jakaś inna forma WPF)
mam procedurę wywołującą okno DaneAdd...
```csharp
public void MoistureControlOpen(object param)
{
int IleDanych = 2; // Ta zmienna ma docelowo być pobrana z konfiguracji.
if (IleDanych > 8) IleDanych = 8; // Zabezpieczenie przekroczenia limitu 8 danych...
View.DaneAdd daneadd = new View.DaneAdd();
daneadd.IleDanych = IleDanych; // Ile ma par danych;
daneadd.ViewModel = new MoistureViewModel();
FirstFloor.ModernUI.Windows.Controls.ModernDialog Dialog = new FirstFloor.ModernUI.Windows.Controls.ModernDialog()
{
Title = "Parametry danych",
Content = daneadd,
};
Dialog.IsEnabled = true;
Dialog.Buttons = new[] { Dialog.OkButton, Dialog.CancelButton };
Dialog.ShowDialog();
if (Dialog.DialogResult.HasValue && Dialog.DialogResult.Value)
{
// dalsza obsługa danych...
}
}
</CODE>
Wydaje mi się że to dobrze rozumiem z przykładów dostępnych na necie ale jednak jest coś nie tak.
W niektórych miejscach w pliku XAML jest wpis Text="0.00", bo nie działa mi
<TextBox Name="param1" Text="{Binding MED1}, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" TextAlignment="Right" Width="95" Grid.Column="3" Margin="0,10,0,10" Background="White" Foreground="Blue" HorizontalAlignment="Right" />
nie wiem czemu MED1 to nie jest własność MED1 z pliku DaneModel ani z DataAddViewModel.
Nie wiem w którym miejscu czegoś mi zabrakło. Jestem otwarty na sugestie.. Z góry dzięki.
Pozdrowienia dla wszystkich.
