I would like to make a layout with a sidebar that can have widgets from different modules. Lets say there shall always be a login widget at the top if the user isn't logged in then it shall show user info. The getting started album guide could use it to display the latest albums and so on, i hope you understand how i want to use the sidebar.
Could it be done with a config file in autoload and a small code that read that config and calls the widgets on every page load?
There are several ways of page composition in Zend Framework 2:
1. Switching between Layouts
By default, ZF2 provides you with a single layout template layout.phtml.
In real-life applications, you will probably need to have several layouts
and switch the layout for certain controller/action. In each of your layouts, you will be able to show different widgets/sidebars.
2. Partial Views
A partial view is a .phtml view template file which can be rendered by another
view template. Partial views allow to compose your page of pieces and reuse pieces
of view rendering logic across different view templates. This is accomplished through the Partial view helper.
3. Placeholder View Helper
The Placeholder is another useful view helper allowing for capturing HTML
content and storing it for later use. Thus, analogous to the Partial
view helper, it allows to compose your page of several pieces.
4. Forward Controller Plugin
With the Forward controller plugin, you are able to call an action (for example, the action rendering some widget) from another module/controller from your controller and grab the output of that action. Then you are able to incorporate that output into your page.
5. Use View Models for Page Composition
When you write action methods for the controller classes, you use the ViewModel
class as a variable container for passing the variables from controller to view template,
and for overriding the default view template name. But, actually the ViewModel class is more than just a variable container plus view template name. In fact, it is closely related to the layout and page composition.
The third big capability of the view model class is that it allows for combining several
view models in a tree-like structure. Each view model in the tree has the associated
view template name and data variables that can be passed to the view template to control
the process of rendering.
This feature is internally used by Zend Framework 2 when "combining" the layout view template and the view template associated with the controller's action method. ZF2 internally creates the view model for the layout template and assigns it with layout/layout view template name. When your controller's action method returns the ViewModel object, this object is attached as a child to the layout view model.
So, you can attach your own view models to the default view model to render the page of pieces that you want.

I am rather new to ASP.NET MVC5. I know server side controls are not working directly in MVC, but there will be some way by which we will get similar controls in MVC5 for rapid development. Can you suggest me how can I find such controls? Can you list out all such mostly used common controls for MVC5?
Thanks in advance.
There's no concept of a "control" in MVC. There's various things that function similar to Web Form controls, but it depends on what you're trying to do.
HTML Helpers are similar in that you essentially call a function that returns rendered HTML. You can extend HtmlHelper to add your own.
Child actions function as a sort of separate request within the context of the main request. They accept parameters like an action, can do all the backend stuff an action can do (query database, etc.) and return a view rendered based on a model, like a normal view.
A partial view, in general, can function as a control as it allows you to insert a snippet of HTML somewhere.
Editor templates and display templates can be used in conjunction with Html.EditorFor and Html.DisplayFor, respectively to render a form field or some sort of HTML display for a particular property on your model.
I have a standard Master-Detail Interface and I'm using Coredata and cocoa bindings.
The Master list uses a NSOutlineView and a NSTreeController, these items remain static but different details views are swapped in and out.
So, how do I set the content of the array controllers in the different detail views to correspond to the selection in the outlineview in the Masterview?
This is straight forward if all the array/treecontrollers are in the same .xib file. initially, I tried creating an Outlet from of the Treecontroller and passing this to the orther views as they are created, but I don't think this is correct.
Any suggestions?
You can use an array controller or a tree controller for as many views as you like. In your specific example, I would make the masterview owner of the tree-controller (unless you have a compelling reason to go yet another level up). Then each detail view that gets swapped-in would also have view controllers. That controller would have an assignable "tree-controller" property that would get set before its view is loaded to the value of the "master" tree-controller. Within the Nib files you can use bindings (to the tree-controller of files-owner) as you normally would.
When using an Include Page to dynamically load a custom control onto an XPage, is there a way to pass custom property values to the custom control as part of the include?
Peter, the include page doesn't load a custom control but another XPage. Pages don't have properties. However... the page becomes part of the component tree, so you have access to its contained controls using getComponent("thecomponent").getParameterMap (Off my head, might be called slightly different)
Does that help?
I am currently working on an Orchard module. This module contains an MVC application including the views. I would like to make the module as configurable as possible. One of the items that I would like the customer to configure is the way the MVC views from the module look. Part of it will be determined by the theme. But not everything. Consider the following scenario:
The module contains a view for placing an order. The view displays a form in ´normal view way´. That is field labels and input labels. But at the head of the form each customer must be able to define his own set of instructions to display. Or maybe the customer wants to put there a message for pointing the customer to some other actions.
In the most ideal way I would have a content page where the customer can put all kind of content and one specific block that is the result of the view of the module. Kind like a web part. I can´t find out if it is possible and how that is achieved.
Edit for clarification
Module creates a page like this:
TITLE
FORM
So both title and form are outputted by the module controller.
I have managed to create a layer with the condition that the url matches the page with my form.
I have added a HTML widget to this layer in the content zone with position 1 (tried 0 to).
However the pages looks like this:
TITLE
FORM
WIDGET
instead of
WIDGET
TITLE
FORM
Returning a ShapeResult from your controller action will ensure that your view is themed and benefits from widgets, which are your "kind like a web part" thingies in Orchard.
I'm trying to accomplish switching views without using a navigation controller, tab bar controller etc. I am currently accomplishing this using Cocos2d director class replaceScene method. My application will need to have around 40 view controllers, each with a few UIButtons that could take them to any other view controller.
For instance View controller 1 may have buttons that take you to view controller 2
View Controller 2 may have buttons that link to 3,4,5,12
view controller 4 may need to link to view controller 17, 5 and 3
Every tutorial and bit of documentation I've read only discusses using Navigation Controllers, Tab bars or pushing views modally. None of these solutions fits my particular requirements.
Cocos2d has the "replaceScene" method which does exactly what I need, but mixing the many UIKit controls that I need makes developing this entire project in Cocos2d a nightmare.
I'm looking for something where I can have the user tap a button which will load a specified view controller/view transition to that view, and unload the previous view controller from memory. Any ideas?
Have a root view controller which has references of your view controllers. Also make a weak reference to the root view controller in each view controller, as in a delegate pattern. If one of the view controllers wants to make a view transition, send a message to the root view controller. Let the root view controller hide the current view and unhide the next view, using an animation if you want.
Basically you are implementing a view container much simpler than UINavigationController and UITabBarController. You could probably achieve the same thing using the tab bar controller and hide the tab bar view, but I would implement a custom one.
