• Common Navigation UI and Authorization-driven Sitemaps

    Navigation-driven Silverlight applications tend to share some common pieces of UI.  Traditionally, this has required sprinkling HyperlinkButtons throughout the application’s XAML.  For ASP.NET a number of controls intended to drive navigation exist.  These controls are driven by a sitemap, integrate well with authorization and roles (through sitemap trimming), and provide common user experiences around hierarchical application structures such as a TreeView-based list of hyperlinks and Breadcrumbs or navigation paths.  These controls provide the user with context as to where in the application/site they currently are as well as where within the application they can go.

  • Samples updated and code in comments

    Hi folks!  Just a super-quick note: in the last week, I’ve updated most of my old samples (it should be everything except for the one from my PDC talk – that one is a fair amount more work due to breaking changes in RIA Services since the Silverlight 4 Beta) that were build on the Silverlight 4 Beta and RC.

  • A "refreshing" Authentication/Authorization experience with Silverlight 4

    At the beginning of the year, as part of a series of posts about the INavigationContentLoader extensibility point in Silverlight 4, I described a way to use a content loader to do authorization before allowing a user to navigate to a page.  With the content loader, you can either throw an exception when an unauthorized user tries to reach a protected Page, redirect your users to another Page, or return a different page (e.g. a Login page) in its stead.  This makes for a fairly nice experience for your users, wherein they are taken directly to a login page (or at least a page with more information about why they cannot access the given page) when they lack the credentials to reach the page they are requesting.

  • Making printing easier in Silverlight 4

    Well, what an exciting week!  First Visual Studio 2010 is released, followed by Silverlight 4 yesterday!  Consequently, I was inspired to post about something new!  I’ve been spending some time looking at the new printing feature in Silverlight 4, and while on the surface it looks like a pretty simple and lower-level set of APIs, it’s possible to build rich frameworks on top of them for accomplishing common printing tasks.  In this post, I’ll take a look at an attempt I made (and added to SLaB) at building such a higher-level API over printing that makes printing collections of data easier.
