Once the initial binding occurs, changes to the value of an element's Favorite property does not cause the item to show up or disappear from the Favorites Listbox as is desired for the reason noted at the beginning of the post. To work around this I've tried firing both Events when the Favorite property is changed to get the UI to update, but neither worked and I'm confused why not. This may be the unusual thing that is causing things not to work for me.I have a telerik Rad Tree List View which is populated by a C# Data Table class. How do you expect UI to update, when you are doing operations on completely unrelated object instance?All i want is to refresh the Rad Tree List View UI when items are removed or added to the Data Table (i dont care about when item properties change for now). Please consider changing the following declaration: public class Test : Observable Collection, the type of the child element should not be like the collection type itself.
The end result is that changing any individual's (or team's) hours is reflected in the parent.Okay, so the Display Member Path isn't working at all, i have tried all day to fix it and nothing i found on the internet works...I tried to do all of the stuff only with the code and it still didn't work...Hence the solution with the readonly backing field.If doing like that you will not be able to assign a new Observable Collection and you won't break the binding by assigning a new object to the backing field.
