c# - XAML - Update text on different property update -

so have following xaml:

<textblock text="{binding disconnecteddevices, updatesourcetrigger=propertychanged}" /> 

the view model has following properties:

public string disconnecteddevices {get; set;} public ienumerable<ideviceinformationvm> devicecollection {get; set;} 

there's method gets called raises property notified event:

public void devicecollectionchanged() {     raisepropertychanged(() => devicecollection); } 

i'd update value in textblock when devicecollection changes. i'm aware call raisepropertychanged on disconnecteddevices i'm wondering if possible update textblock on different property change event.

thanks all!

edit: suggestions using observablecollection instead of ienumerable, unfortunately, i'm not @ liberty change collection type..

the devicecollectionchanged method called whenever collection changes (tedious know...)

further edit: have gone ahead with

raisepropertychanged(() => disconnecteddevices); 

i appreciate not enough information might have been provided in question trying do, apologies that

i not sure if current code works, assuming works. why not use - observablecollection<ideviceinformationvm> instead of ienumerable<ideviceinformationvm> devicecollection wont need devicecollectionchanged event. taken care.

yes can raise

public void devicecollectionchanged() {     raisepropertychanged(() => devicecollection);     raisepropertychanged(() => disconnecteddevices);    // or raisepropertychanged("disconnecteddevices"); whichever works } 

see question, might implementation of notifypropertychanged multiple properties- wpf notify propertychanged property
