WPF application using MVVMCROSS

阅读更多关于 WPF application using MVVMCROSS

问题 I recently came across MVVMCROSS which I think is a very good idea to solve cross platform issues. So I was tempted to port over an application I was working on and my entire libraries to make them more portable. Now I am trying ti bind my viewmodels to the views and I am facing several issues and questions... I have seen the examples of how navigation works and how to start the first view which works fine. However, for my application I cannot use this.. My main view consists of a menu bar at

Android MVVM Cross v3 - How to Create a ListView with alternating row colours

阅读更多关于 Android MVVM Cross v3 - How to Create a ListView with alternating row colours

问题 I'd like to create a ListView that has an alternating background colour for each row. I'm new to Android development in general, never mind Xamarin and MVVMCross as well :) There are some examples of doing this in the Android world and the Xamarin world, but I can't figure out how to set this up in an MVVM Cross way. My understanding is that I will need to implement this in the Android specific view code and to do that I will need to set some adapter on the ListView that can programatically

Who should create view model instances in MvvmCross

阅读更多关于 Who should create view model instances in MvvmCross

问题 Just to make it clear: I know MvvmCross is very flexible about where and how view models can be created. My question is more about proper separation of concerns, to simplify design of complex cross-platform applications. Consider we have an app with customer list and customer details.

问题 I am attempting to create a bindable RadioElement to use in a MonoTouch.Dialog implementation in MvvmCross, and following the pattern in https://github.com/MvvmCross/MvvmCross-Tutorials/tree/master/DialogExamples/DialogExamples.Touch/BindableElements (as suggested in MvvmCross Monotouch.Dialog binding data to a table), I created the following class: public class MvxBindableRadioElement : RadioElement, IBindableElement { public IMvxBindingContext BindingContext { get; set; } public

How to use MvxCachingFragmentActivity?

阅读更多关于 How to use MvxCachingFragmentActivity?

I'm trying to work with navigation with only Fragments, for tombestoning, saving total navigation stack and paramaters, etc. (working with Xamarin.Android and MVVMCross) I think MvxCachingFragmentActivity contains all needed parts. But I can't seem to get it to work and I can't find any example project that works with FullFragging. Closest thing is the example from Cheesebaron https://github.com/Cheesebaron/MvxFragmentsAndHamburger , after removing some comments to load the ViewModels it worked but not for FullFragging and total NavigationStack recovery after activity has been destroyed.
