Observablecollection binding not updating Nigeria sex chat online

In the XAML I have bound the Items Source to the Customer Summary Details Property.This was so I didnt have to bind to Selected Customer. The Selected Customer property has a get and a set method, and the set calls On Property Changed for the OTHER property, Customer Summary Details, letting the XAML know that the underlying collection has changed and to update.I have a CLog Entry model class which basically wraps a string.My Problem is that the list does not show any data.

Im designing an MVVM WPF app, and have a View Model which has a property called Selected Customer, of type Customer.The Observable Collection is responsible for notifying its own changes, not changes pertaining to its items.You Should Notify Property Change("Sub Cust Value") in the setter of your Sub Cust Value.I have delved into the value of the returned collection at this point, and the value within the list is the updated value, however nothing is getting reflected on the GUI, so I am puzzled as it seems the GUI is calling the get method to update it on the On Property Changed() call, but it is not reflecting visually.

UPDATE - CODE INCLUDED Sorry for not including code, I thought it would be easier to just describe but here are the main View Model properties You're not modifying the Observable Collection itself (such as adding/removing items) but the items INSIDE that collection.With that said, my collection is updating correctly, but my datagrid will not 'uncheck' the previously checked boxes, who's bound value has been changed to false. I have found a solution but it involves multithreading, which seems like an improper solution to this problem.
