    RadGrid for ASP.NET Ajax and DomainDataSource

    In July Microsoft released a preview of its upcoming Silverlight 3 RIA Services Framework which comes along with a new data source control – DomainDataSource. The DomainDataSource introduces a new way of accessing data by giving us a nice separation from the particular representation of our Data Model and more control over how the data is being retrieved or manipulated. This post will provide you with a quick walk-through on how to use the DomainDataSource with our RadGrid control. Install Microsoft .NET RIA Services July 2009 Preview As mentioned above the DomainDataSource control is part of the MS .NET RIA Services Framework, so...

    API changes introduced by the new CoverFlow control

    If you missed the buzz, the Telerik team plans to distribute a beta release introducing new controls that will be officially included in the Q3 2009 release scheduled for November 2009.

    RadScheduler for Silverlight learning series, part 4: So what is RecurrenceExceptionHelper?

    RadScheduler for Silverlight learning series, part 3: Add, Edit, and Delete Appointments

    If you've been along for the ride so far with this series, you already know that we've hooked a SQL database up to RIA Services using an ADO.Net Entity Data Model and a DomainDataService data context.  If you've missed it, check out the prior two posts (or search RadScheduler for Silverlight learning series in the Telerik Blogs site).  Now that we're here, we have three more events to handle and we've got a fully-functional RadScheduler for Silverlight hooked up to RIA services. First up, the two easy events- AppointmentAdded and AppointmentDeleted. AppointmentAdded Event This event is pretty straightforward and does not require very...

    Silverlight: RadChart for Export to Image

    Good news everyone! Exporting Silverlight charts to images has been a common request for our Silverlight chart. I’m glad to announce that the functionality is already done and checked in our development branch. This means that everything is on track for the Q3 2009 release (and maybe a beta release before that!).   But why not for Q2? Well, there are a couple of reasons. Q2 release was still Silverlight 2 based and there were technological difficulties that didn’t allow us to implement this feature. Firstly, Silverlight 2 didn’t have the writeable bitmap class which facilitates rasterizing the chart rendering and secondly...
