When I create a ContentPage in Xamarin Forms, the code behind partial class gets decorated with an [XamlCompilation(XamlCompilationOptions.Compile)] attribute. I know I can add an assembly level attribute for this, but is there any way to prevent the page level attribute being used besides explicitly removing it?
Say I decided to Skip most pages instead, I will have to go and change that attribute on every ContentPage.

You should suggest this on the xamarin uservoice site and post a comment with a link to the suggestion so others can vote on it.

I was trying to digg something on this topic before, but have no luck. What I'm trying to achieve is pretty simple, but seems to be hard to achieve :-)
I have a WP8 app (C# XAML) and I need to implement global messages (something like toasts) which could be displayed across whole application no matter of current navigation processes. Such toast message(s) should be displayed even while user is navigating between pages. To use the built in toasts is not a way (in case some other solution exists) since I'm possibly in need to have more than one message displayed at the same time (each one is independent of another) and should disappear after specified period of time.
So, my question is. Is there any way how to implement and use some kind of global view instance which sits above all pages and can be called from any page?
All I found until now is the possible ability to use PhoneApplicationFrame, but I would like rather avoid that if possible. I'm still unsure if this is even the way it can be done, but I suppose so. Do you have any alternatives or assurance this is possible and only way to achieve this goal?
Thank you all for your time and answers.
You can have UerControl for the Functionality you are looking for. It is Control that has its own Seprate Xaml and cs file. You can call it from any page into your Project. UserControl provides the base class for defining a new control that encapsulates related existing controls and provides its own logic. You have a XAML file and C# class file for a user control. The class file extends the UserControl class and adds additional behaviours and properties. The XAML file encapsulates the composing controls, the styles, the templates, animations and whatever necessary to form the UI. Since it is a just composition, it is really easy to create. for more Reference you can go here Why and how to create a User Control in Windows Phone
I have ended up rolling my own custom navigation using a single master page. As such any global controls are instantiated once at startup. Navigations are called from my viewmodels and result in usercontrols being removed and added to the visual tree as necessary (using transition animations to give the impression of page navigation) This works but im not sure whether it is best practice and would appreciate some opinions and comments on this. Certainly it solves the problem of global views described.
I tried the simple approach: editing the Contact page in the admin interface and selecting my new template within the Advanced Options section. But the form does not get displayed.
I also generated the override views:
rake refinery:override view=refinery/inquiries/inquiries/*
But looking at the app\views\refinery\inquiries\inquiries\new.html.erb file, I did not see an obvious solution to this issue.
I found this issue on github but it does not offer much detail: https://github.com/refinery/refinerycms-inquiries/issues/45
I suspect a big part of the issue is that when I change the template setting under Advanced Options, it's changing the view from the default inquiries new.html.erb to one of the standard view options. The problem is inquires extension new view is not listed as an option.
The short answer here is: you can't.
In the course of struggling with this, I came to realize that in most cases you probably don't want to be switching layouts. Not in the casual manner that I was, anyway.
What I really wanted were alternate page views. The basic web page layout and styling can be fully modified through views.
Realizing this changed my objective. I didn't need to change the layout for the inquiry pages. I needed to match the inquiry page views to my default page view. I was able to do this by overriding the inquiries extension's new and thank-you views and editing those files so that the markup and styling matched that of my default page view.
Simple enough. The only downside is it's a bit un-DRY. If I were to alter my page view, I now would likely have to repeat the changes in those two views as well.
Today is my first day working with MVC and I am trying to convert my existing Web Forms website into an MVC 4 site.
I have done some reading and am starting to understand how things work but one thing I can not figure out is for the new Layouts (replacing MasterPages) where is the equivalent to the codebehind file? In my current site I have a Master Page that defines the general look and feel but also runs some code in the codebehind to changes a few things dynamically (for localization and DB generated menu system).
So now that I am using MVC and Layouts I can not figure out where I would code all that at, can anyone please point me in the right direction?
(I know MVC does not have code behinds it uses controllers for it.)
As you Know MVC is three layer architecture.
Model
View
Controller
Model is the data entities. You need to store, or show the data.
Views are the html or presentation layer which would be rendered to users.
Controller are the code behind file all of your code would go in controller. It gets data from Models and apply business logic and then pass to views to show or get updated data from view and pass to models and then save to database.
_layout.cshtml file is present at path of ~/Views/Shared/_Layout.cshtml. It is master-page in mvc. You would see your partial-views contains
Layout = "~/Views/Shared/_Layout.cshtml";
this line at top of page. You can change master-page for any views and you can have multiple Layouts.
Layout contains many partial-views like left-navigation, Top-Navigation and content. each of which can be customized from controller.
Here are some links might help you:
MVC Tutorials
Introduction to MVC
Create a Base Controller class and make all your controllers inherit from it.
The MVC equivalent of WebForms' Master Page codebehind is then this Base Controller, where you can put code you need for multiple controllers.
How can I execute common code for every request?
You can't find any examples of what you're trying to do, because that's not how it's done in MVC. There is no equivalent to code behinds.
You're "trying to do" the wrong thing. MVC layouts are simply template files. They have no code behind, and they should have no functionality besides simple display logic.
MVC is a different paradigm from WebForms. You don't use have server-side controls like WebForms. Therefore the idea that you have content in the layout that does it's own thing violates the MVC principles.
You're basically stuck in what's known as the XY problem. That's where you are trying to achieve certain functionality X, and you believe to do that you need to do Y, so all you ask about is Y... when X is what you really need to be asking about.
Please explain the actual thing you are trying to do, and don't assume that it must be done in the way you've always done it. For instance, if you want to localize something, then ask how to localize something. If you want dynamic content somewhere, ask how to do that, but you need to be more specific about these individual problems, and not just gloss over them as you have done here.
I have dojox.mobile.ListItem inside an dojox.mobile.RoundRectList got from web service. I need to implement drag and drop functionality for the list and handle that event.
Normal drag and drop in dojo is working fine with dojo.dnd.Source. But in mobile.ListItem I dont find any links. I'm not sure whether its possible or not.
It would be great if any one provide sample code or useful link regarding.
Thanks,
Siva.
Enable the editable property on your dojox/mobile/RoundRectList and subscribe the "/dojox/mobile/deleteListItem" when removing an item.
The explanation is here and there are examples here under EdgeToEdgeList
I am having working with sandbox solution. i have one .aspx page in my solution and i have placed one button tag in that page, i need to write server side code for that button. But it is showing "The event handler 'OnClick' is not allowed in this page." . Does codebehind is not allowed in sandbox solution. Or indirectly how can i write my c# code for that button.
I know we can do it by creating one webpart and show that webpart in page using "WebPartPages:SPUserCodeWebPart" tag . But i want to confirm whether we can write codebehind for an asp page in some way or not.
Without changing the web.config file (which would not be recommended in this case), inline code or code behind files are not supported outside of the layouts folder (which you cannot deploy to with a sandbox solution).
However, you should be able to create a class and then set the inherits attribute to point to that class, instead of referring to the class in a code behind file.
