    Survey: What do you want to see in upcoming RadTips episodes?

    It's been a while since I posted my last RadTips episode. In fact, with recent conference travel, the new Telerik.com web site, and preparations for the Q3 2008 release I've hardly had time to get anything recorded. But now that all that is in the past it's time to get rockin' with some fresh content. For those of you who don't know, RadTips is a screencast I do on a regular basis which provides quick tips that you can use with the RadControls for ASP.NET AJAX. Each episode focuses on a specific RadControl feature and is fairly short (approximately 5 - 10 minutes),...

    SQL Server 2008 Error: 'Saving changes is not permitted.'

    Tonight I ran into the following error message when using a freshly installed version of SQL Server 2008 in a new project. Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created. The error appeared after I created a new table, set up it's primary key column, clicked save, and then tried to modify and re-save the table again. The reason this error dialogue is being...

The following posts will use this feature to build running applications. - OpenAccess comes with 2 possible ways to generate the persistent model: Forwad Mapping: Write the persistent classes first and let then OpenAccess generate the database schema.

    Animation with RadChart for WPF.

    Hi everyone, My name is Velin Angelov. I am a member of Telerik's Charting team and here I am going to write about a feature of the RadChart for WPF which you might find useful while having fun with it. RadChart for WPF was shipped with the 2008.Q3 release and one feature all of the charts have in common is being animated. From this point on there are three options: You are absolutely happy (as you probably will) with the default animation settings provided by RadChart. In this case you simply keep on coding. You totally disagree with the way RadChart is animated and...

    Look Ma, I’m on TV!

    Seems I’ve gotten my 15 minutes of fame after all (more like 5). During PDC’08 Todd and I had the chance to meet with Adam Kinney from Microsoft and talk about one of the coolest new telerik products – the WPF Charts and Gauges. The video is now up on Channel 9 and can be accessed here. In the mean while we pulled off our first release and the charts and gauges are now a part of the WPF controls suite.

    Can your grid control do this?

        In “First Look at Silverlight 2” Scott Gu showed how easy is to change the visual appearance of a Silverlight application using the standard features of the Silverlight Grid control: While reading the blog, it occurred to me that it would be very easy to achieve similar effects with RadGridView for WinForms. With the latest version of RadGridView you can change the row layout using different view definitions in a very simplistic and easy way:     Using parts and ideas from Scott’s article, I compiled a small application that gets a list of article from digg.com via web services and shows them in RadGridView...
