I have a MasterDetail Page that serves as a Navigation Menu for my App (ie it navigates between MainPage to settings to aboutUs Page etc), the Master Page houses a list of the Pages. When I select an item from the list, The Detail page provides me with the Page in Question. Now I have a page that creates an instance of a object, i want to pass this created object to the mainpage and add it to the mainpage's observablecollection of objects. This implies I want to change the detailpage current content from the creating page to the mainpage, How do I go about this. Thank you.
