Find out the recipients of the OnPropertyChanged event in WPF

Question

I am doing reverse ingineering in a project written by some one else. The GUI is made in WPF and has several windows. One class has implemented the INotifyPropertyChanged interface and 2 properties fire the OnPropertyChanged event to signal the data.

My aim is to find out which control profits from this event. How can I find all controls that actually harness the information when the OnPropertyChanged event from the 2 properties is fired?

Looking for all references of the delegate did not lead to any results. There is no explicit registration of this event. I remember vaguely that this connection can be established in the XAML code in WPF using binding, but I don't know enough about WPF find this information on my own.

Any help would be greatly appreciated

Answer 1

Suppose your two properties are named FirstProperty and SecondProperty. Just look in the XAML for binding references to them like:

{Binding FirstProperty}
{Binding FirstProperty, ...}
{Binding [whatever].FirstProperty, ...}
{Binding ..., Path=FirstProperty, ...}
{Binding ..., Path=[whatever].FirstProperty, ...}

Controls that use those bindings are the one that will get the PropertyChanged event. For instance, if you find:

<TextBlock x:Name="myText", Text="{Binding FirstProperty}" />

this means that the above TextBox control will react to FirstProperty changes notified by the PropertyChanged event.
