Binding works in Blend but not in Unity
Posted: 29 Mar 2017, 20:34
Hi Guys,
I created a template which binds to a viewmodel. It works perfectly in Blend. It will also render in the unity editor if I eliminate the bindings and put the values in directly. In my template, I am using an ItemsControl. When I bind the values to the ViewModel it no longer works. I made sure that I am using an ObservableCollection and INotifyPropertyChanged as you demosntrated in your samples. Here goes the template:
Am I doing something wrong with the Binding? Please let me know.
Thanks
