In databinding, how to find which control invoked the "getter" of a property data-bound to it, when the PropertyChanged event is raised?

Question

Hi,

I am developing a Silverlight 3 application, in which I have a boolean property in my Model class (using MVVM approach) that's bound to "IsEnabled" target property of two buttons. I need to find out which button invoked this boolean property when I raise the PropertyChanged event (i.e. during databinding).

Is there something in the callstack that I can look for to figure this out? Or is there some other way by which I can do this?

TIA... Sudeep

You could check the call stack e.g.

var st = new System.Diagnostics.StackTrace();
var callingtypeOfAMethod = st.GetFrame(1).GetMethod().DeclaringType;

i hope this gets you the idea. you can get the calling control type using this.
