If you are using an asp:hyperlink to another page in your provider hosted app you will see the SharePointContextProvider will not be able to handle the redirect. To fix the problem you need to add a click event and call a redirect in your code behind.

For safety reasons apps are seperated from the SharePoint where they are installed on. Apps are installed on other domains and that is how the seperation works. Apps can't contact the SharePoint, because Cross-Site-Scriptingis blocking it. But there is still a way to get data from the SharePoint and with this way comes a permission concept into the app world. Permissions There is a library, called the Cross Domain Library, that allows to communicate with a SharePoint from app site. This library is aviable on every SharePoint 2013 and is easy to call. But wait.. if it is so easy to call a library that can get SharePoint data it is not saver than before. This library contains more than communication.. it authentificates the app against the SharePoint and asks for permissions. This happens right after the installation of the app. The installing user will be asked to grand permissions for the app. But how does the app know what permissions are needed? Asking for permissions is you...

The biggest innovation in SharePoint 2013 is the app-architecture. With this innovation it is possible to install applications (apps) on a SharePoint. This applications can be developed by yourself or you can buy them in the SharePoint Store. They are totally detached of the SharePoint and got their own area. They can contain own lists, have own sites with custom code and they have their own interfaces. But it is possible to communicate with the SharePoint. My first app To develop an app you need Visual Studio 2012 or above and a development SharePoint. To begin start Visual Studio as administrator and click 'New project...'. A mask opens where you can choose a template. Go to 'Templates' → 'Visual C#' → 'Office/SharePoint' → 'Apps' and select 'App for SharePoint'.

Before you create a Page Layout there are two questions: - What is a Page Layout? and - What do you need to create a Page Layout? What is a Page Layout? A Page Layout is a way to design content on sites. You can create content areas and place them with CSS. Simplified: it is like a form for list items. A site is nothing else than an item in a library, so you can see the layout, that you build, as the display form, the edit form and the new form. What do you need to create a Page Layout? You will need to download and install the SharePoint Designer 2013 , but the most important thing, to make you the less work as possible, is that you know what you want to design and what content you want to display. I recommend you to create a custom Content Type for your Page Layout. It will make it a lot easier to add all the columns you need. It is also recommended to got some knowledge in HTML, ASPX, JavaScript and CSS.
