I would like a RadDropDownButton with a list of checkboxes inside. So I have tried to ways of doing it: with a ListBox and with a RadGridView as a container for that list of checkboxes.
Both ways work well, but problem is that I would like that if I check the first item (called "ALL"), all the checkboxes were checked.
So the gridview itemsource is SalesRepList (ViewModel), which is a Collection of items of the class SalesRep (Model), that has the property IsChecked as one of its parameters.
So I don't have SalesRep in the ViewModel, therefore I cannot use RaisePropertyChanged, and my checkboxes don't update it's value in the view!
All the examples I have seen so far were made binding the IsChecked to a property in the VM, but I cannot do that! (I have tried to bind the IsChecked to a property in the VM but it doesn't bind. Maybe because of the bind of the RadDropDownButton where the GridView is?
