    David Kelley has made some updates to the HackingSilverlightCodeBrowser.

    A couple of bits of news. I did a number of updates to the HackingSilverlightCodeBrowser here: 

    including things like MEF and IsolatedStorage.

    David Kelley has posted about Isolated Storage and how to save name value pairs.

    In its most simple form Isolated Storage allows you to save name value pairs and retrieve them at some other time the next time your app runs. Granted we could get into XML and text files etc but I'm going to stick with just name value pairs.

    On the Robust Haven site there is a great, very detailed post explaining Isolated Storage and how to use it in Silverlight with a generic repository.

    Isolated storage is a file system. It is called "isolated" because it is rooted to a specific directory which provides the sandbox required for browser security. [...]

    Creating a base generic repository allowed me to centralize common IsolatedStorageFile operations that would be needed any time I wanted to save, retrieve, or delete any type of object from Isolated Storage in my application while still being strongly typed.

    In this post Jeremy Likeness explains what happens if the user is running on their desktop and offline and demonstrates his OfflineCatalog which comes to help in such situations.

    This MEF catalog behaves like the DeploymentCatalog with a few exceptions. First, it will save any XAP file to isolated storage whenever it retrieves one, and second, if the application is OOB and offline, it will automatically load the XAPs from isolated storage instead of trying to fetch them from the web.

    Instead of building my own catalog from scratch, I decided to cheat a little bit and use some of the existing catalogs "under the covers."

  • Silverlight 3 – Open, Edit and Save a Text File to a Location outside the Isolated Storage

    0 comments  /  posted by  Silverlight Show  on  Feb 03, 2010 (4 months ago)
    In this article of Suprotim Agarwal you can see how to open, edit and save a Text File to a Location outside the Isolated Storage.

    I see a lot of question on the forums asking how to edit text files kept on their machine and then save these files back to a desired location using Silverlight. In Silverlight 2, you had to use the Isolated Storage to save a file locally on the user’s machine. The SaveFileDialog is a new dialog control in Silverlight 3 which allows the user to specify a file name and location to save a file. This control can be invoked only through a user interaction. Let us a see a simple demonstration of using the OpenFileDialog and the SaveFileDialog control.

    In this post Gill Cleeren takes a look at Silverlight’s Isolated Storage and shows what can be done with this handy option.

    Isolated storage does not differ that much from cookies. It’s basically a file store for Silverlight: Silverlight applications can store in the Isolated Storage files during a session and retrieve them in a later session. Isolated storage is a per-user per-application storage, meaning that when userA works with SilverlightAppA, he’ll have a different isolated storage from userB working with the same application. Isolated storage information is not deleted when you clear your temporary internet files, it can be deleted through the Silverlight configuration.

    In this article Damon Payne discusses the out of browser support in Silverlight 3, and also MEF and Isolated Storage.

    Silverlight 3 ships with out of browser support which is a particularly useful feature.  Combining OOB with the ability to detect network status can allow your users to consume your Web app without a connection.  Combining both of these features with Isolated Storage and the right design approach can provide a seamless Occasionally Connected application experience using Silverlight 3.

    In part II of this article Malcolm Sheridan demonstrates how to save data locally using isolated storage and then updates the database using RIA services once you’re back online. If you remember in Part I he showed you how easy it is to detect network changes using Silverlight. 

    Well here is part II. I thought it would be nice to use the networking capabilities of Silverlight to either save changes locally using IsolatedStorage when there is no network connection, and when the network is restored, propagating those changes up to the database using RIA Services. This is a very simple application, but I’m trying to show you what is possible.

    In this project Sergey Barskiy implements an Isolated Storage based database for Silverlight.

    The usage of this software is very simple. You create a new database by Calling CreateDatabase. You can add tables to the database by calling db.CreateTable<T> where T is the type of entity to be stored in table rows. You can save database by calling Save, and open the database by calling OpenDatabase. This database supports version changes, so you can update your application and still be able to open the database. You can look for basic use of this database by examining test Silverlight application.

    Peter Bromberg has posted a sample in which he provides a Silverlight Navigation Application that requires the user to enter their user data as a condition of being able to navigate.

    A DataForm is used which is bound with 2-way databinding and a UserSettings class with Validation Attributes. DataContractSerializer is used with IsolatedStorage.
