Question

I have a simple Datagrid binded to an ObservableCollection from the ViewModel. This ObservableCollection is composed by a Custom Type, say ObservableCollection.

The ComplexType only have 2 properties, and only one is editable on the screen. The other one is a bool type that depends on the first.

When I edit the first property, it gets reflected to the ComplexType and it also change the second property. But the second property is not changed on the screen.

How can I update the second property on the screen?

Try this:

public class ComplexType:INotifyPropertyChanged
{
    private object someProperty1;
    public object SomeProperty1
    {
        get{return someProperty1;}
        set
        {
            someProperty1=value;
            SomeProperty2=somefunc(someProperty1);

            If(PropertyChanged!=null){PropertyChanged(this, new PropertyChangedEventArgs(SomeProperty1));}
        }
    }

    private object someProperty2;
    public object SomeProperty2
    {
        get{return someProperty2;}
        set
        {    
        someProperty2=value;

        If(PropertyChanged!=null){PropertyChanged(this, new PropertyChangedEventArgs(SomeProperty2));}
        }

    public event PropertyChangedEventHandler PropertyChanged;
}
