    RadControls for WPF/Silverlight Q3 Beta 2 release is live!

    Hey everyone, start your morning off right by heading to your client account and downloading the new beta releases for RadControls for WPF and RadControls for Silverlight. Or you can start at Telerik Labs and work your way from there. :) In our RadControls for WPF suite, you now have access to exciting new controls like RadRibbonBar and first looks at the WPF versions of RadMenu and RadContextMenu.  Check out the browser based demo, or better yet download the beta bits and see it for yourself.  With RadControls for Silverlight, you get updates to RadTileView, RadOutlookBar, RadRibbonBar, and more- all based on community feedback...

    Quick and painless Byte Array to Image converter for RadGridView for Silverlight

    We received a question today in regards to a binding issue with RadGridView, or rather an issue with an Image in a custom cell template that the customer was trying to bind to a custom value.  They had the basic setup right: <DataTemplate>    <Image Source="{Binding ImageData}" /> </DataTemplate> But something wasn't quite working right.  After doing a little digging, we found that they weren't sending a URI to the Image but rather a byte array.  Unfortunately, the Image control in Silverlight doesn't quite know how to pick up on this so you need to convince it- with a converter. With a little bit of coding...

    Making a Step chart in RadChart for Silverlight and WPF

    So a customer emailed into our office yesterday asking about whether RadChart for Silverlight supported a Step chart type.  Well, while we do have a boatload of chart types already, Step is currently not one of them.  But a Step chart is really just a Line chart with a bit of extra work, right?  With the help of our chart wizard Manol, we were able to show that the LineSeriesDefinition could, in fact, replicate a Step chart.  But that was with setting all points manually and took a bit of thinking to make sure all the steps looked right.  So...

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

    For those of you following this series, I'm going to take a slight detour to explain one of the little bits of magic that we have been using to make loading and saving appointments very easy: RecurrenceExceptionHelper.  If you downloaded the sample application from part 3, you'll see this sitting in the Silverlight-RIA-Entity folder (aka the Silverlight portion of the solution).  The first thing you might be asking is where the need for such a class comes from.  Well, handling Recurrence rules and Exceptions are two of the more complex things that you can do when working with appointments.  When...

    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...
