As you may recall from my previous blog post, we're revamping this application and bring it to the latest and greatest that is available in Silverlight today.  Coincidentally, Q2 2010 SP1 just came out today (check your accounts!) and I figured the best first place to start would be with something I removed previously- validation.

Since I redid the model for this application, I completely scrapped all of the previous validation because I knew I could now take advantage of using INotifyDataErrorInfo, which gives us a slightly more graceful way to handle asynchronous validation in our application.  I would explain all...

The RadTransitionControl can be very useful when you want to switch between controls. In this blog post I will explain two common scenarios:

1) Switching between 2 UserControls, which is applicable for both WPF and Silverlight and

2) Creating attractive navigation between pages very easy, applicable for Silverlight.

Now, point-by-point:

1)   For this approach you will need to create 2 UserControls. In the root page define a RadTransitionControl and give it a x:Name. Then, on a button click change the Content property of the TransitionControl with the chosen UserControl. 

Here you can find attached you will find a simple WPF example of the above-mentioned technique.

2) For the second scenario we need to create...

The Keyboard navigation major feature is now available with the Q2 ServicePack1 release. You can start using it immediately in WPF and Silverlight and as a result enhance your application’s Usability and Accessibility.

Try it yourself.

The API

The API is pretty straight-forward. First you should enable Key tips, for the instance of a RadRibbonBar, with simple attached property like follows.

Then you can attach key tip text to every component in the RadRibbonBar with simple line of code.

Some components need alternative key tip activation text like the RibbonGroup. Foe example one could be used for the DialogLauncher button and one for the group itself, when the group...

It has been a while since I've had a nice, lengthy, code-a-riffic post on here so I wanted to start this off right.  By the title of this post I've already given up part of the surprise- I'm revisiting the Silverlight Recruiting Application and bringing it up to date.  For those of you that don't remember (or haven't seen this series), the concept behind this application was around a real world internal use here at Telerik.  More specifically, we keep growing and therefore our HR demands have grown, requiring something more robust than a very organized use of Excel and...

We've just released JustMock Q2 2010 Service Pack 1 so feel free to log in to your telerik client accounts and download the latest bits.

You can read more information about what we've managed to fix and what we've added here.

Have a great and productive day!...

The first blog post on this topic described how to create a domain model from an existing database and set inheritance relations between the generated classes. It was also shown how to use vertical mapping. In this post however, the focus is on the flat strategy (multiple classes mapped to one table) and forward mapping.

Let's add some new classes to the model from the previous post:

The new classes - Coupe and Lomousine, will be mapped to the table of the Car class. To do that, select each of the new classes and change the "Mapped to" option in the Details Editor...

Yesterday we released the first of series of Service Packs, following our outstanding Q2 2010 release. The first drop is for RadControls for WinForms, and features a fair amount of bug fixes.

A noteworthy feature made it in Q2 2010 SP1 - and this is the ability to quickly switch from [now obsolete] RadPanelBar, RadTabStrip, RadComboBox, and RadListBox controls to their new counterparts: RadPageView and RadDropDownList and RadListControl. The idea is simple, and the transition process is quick, transparent and painless. Simply download and install RadControls for WinForms Q2 2010 SP1 and upgrade your application to use the latest version. Once you...

With the 2010 Q2 release of Telerik OpenAccess ORM we introduced a lot of new features, including forward mapping capabilities for the visual designer. This makes the life much easier when it comes to defining a domain model which contains classes in a hierarchy. Until now it was only possible to use the vertical strategy for mapping a class hierarchy but in Q2 we have enabled the flat strategy as well. Any combination of flat and vertical mapping is also supported. This leaves the horizontal strategy as the last one to be supported, probably later this year. Now let's see how those things...

The RadControls for ASP.NET AJAX courseware has just received a fresh update and now includes updates and new additions spread across all ASP.NET AJAX components. You can find the renewed PDF version of the tutorial and the zip download containing the AJAX courseware projects on this page (under the group 'Learning RadControls for ASP.NET AJAX").

Happy programming!

Last month Scott Guthrie announced a new ASP.NET View Engine called Razor. Then Microsoft released the beta of a new product called WebMatrix which was utilizing it. It also employed a new web framework called ASP.NET Web Pages. Then yours truly made a few attempts to use Telerik Extensions for ASP.NET MVC in a WebMatrix page. The end result was promising. I waited for official Razor support in ASP.NET MVC 3. Then Scott “Almighty” Guthrie announced the first preview of ASP.NET MVC 3 which includes Razor support.This week I started to see how to improve Telerik’s Razor story… This blog post shows the end result.
