Wpf contentcontrol binding not updating

We use a similar naming convention for this scenario as we did with view location. Because your View Models may be registered by an interface or a concrete class we attempt to generate possible interface names as well. Locate For View first checks your View instance’s Data Context to see if you’ve previous cached or custom created your View Model.

The final important thing the View Model Binder does is determine if it needs to create any conventional property bindings or actions.

To do this, it searches the UI for a list of element candidates for bindings/actions and compares that against the properties and methods of your View Model.

Rx UI bindings does not work that way; you have to provide a Data Template for them to work: No it's a legitimate bug with the View Model View Host and the Combobox in WPF land Essentially if a Item Template is set and it's a Content Control (which View Model View Host is) it'll call into https://referencesource.microsoft.com/#Presentation Framework/src/Framework/System/Windows/Controls/Combo Box.cs,871 It will then grab the Item from the control, set the Item Template for a new hosted control, and then set the View Model to be the previous View set on the control. A MVVM framework that integrates with the Reactive Extensions for . Mac, Xamarin Forms, WPF, Windows Forms, Windows Phone 8.1, Windows Store and Universal Windows Platform (UWP).

NET to create elegant, testable User Interfaces that run on any mobile or desktop platform.

This transformation effectively assumes you have a folder (namespace) for the different views by removing the word “View” from the end and appending the context instead. One of the functions of Locate For Model is to inspect your View Model to see if it implements IView Aware.

If so, it will call it’s Get View method to see if you have a cached view or if you are handling View creation explicitly.The View Model Locator is only used by the WP7 version of the framework.It’s used by the Frame Adapter which insures that every time you navigate to a page, it is supplied with the correct View Model.If not, then it passes your View Model’s type to Locate For Model Type.The out-of-the-box convention is pretty simple and based on a number of patterns we’ve used and seen others use in the real world.See the section below on property binding conventions. Micro prefers View Model-First development, there are times when you may want to take a View-First approach, especially when working with WP7.
