Dynamically loading JavaScript from within Sandbox
SharePoint 2010 ships with the Sandbox capability that allows you to isolate custom code and run it in a safe manner. And while it offers you some great possibilities it also has some limitations as pointed recently by Wictor. One of such limitations is no access to the Page.ClientScript which is being used to register JavaScript scripts from within Web Parts. Find out how you can work around this limitation using standard capabilities of the SharePoint 2010 framework.
SharePoint 2010 UI Tip: non-obtrusive progress messages
SharePoint 2010 ships with a new User Interface framework that allows you to easily create rich user experiences. While developing custom solutions one of the challenges is to communicate long-running operations with the user: after all there is nothing more annoying than a non-responsive UI. Find out how the new UI framework of SharePoint 2010 supports communicating the progress notifications to users.
SharePoint 2010 Application Pages and Modal Dialogs the easy way
SharePoint 2010 ships with the new Modal Dialog framework that allows you to display dialog windows in an unobtrusive and user friendly way. This is extremely important when creating user friendly solutions as it allows users to preserve their context while providing some additional information. While the new modal dialog framework is definitely a great idea, there is one thing missing in the implementation: support for communicating with custom application pages.
SharePoint 2010 Page Components in Sandboxed Solutions
SharePoint 2010 ships with the new Ribbon framework that allows you to easily extend the Ribbon with new functionality. All Ribbon extensions consist of the UI and behavior, which in simple scenarios can be specified declaratively but in more advanced scenarios would rely on a Page Component. Most samples, that show using Page Components, suggest registering them using Delegate Controls. Unfortunately this makes it impossible to use Page Component in Sandboxed Solutions which don’t support Delegate Controls. So are we forced to use the limited declarative approach or is there a solution that would allow us to register custom Page Components within Sandboxed Solutions?
Easy SharePoint 2010 JavaScript intellisense with Mavention SharePoint JSOM IntelliSense Snippets
SharePoint 2010 ships with the new JavaScript Object Model (JSOM) that allows you to create rich solutions without a single line of server-side code. Using the new JSOM you can create pretty powerful solutions especially when combined with libraries like jQuery. One downside of working with the SharePoint 2010 is the lack of intellisense. This can however be easily fixed. But do we really have to memorize the syntax and the location of all the files we need?
