    Selenium Extensions for RadControls (ASP.NET AJAX)

    Although I ended my Selenium adventure a few months ago, there is a final topic I’d like to cover here. This one completes my set of posts concerning RadControls for ASP.NET AJAX test automation with Selenium. The tool, the Telerik ASP.NET QA team relied on during the past couple of years, helped us catch in time most of the bugs in RadControls that never came into production! A curios fact here is that Selenium 1.0 official release is finally coming soon after many years of development! Check out the recent post on Selenium blog announcing the exciting news. ...

    Looking Forward

    Taking vacation is always nice, but that first day back in the office can be a bit overwhelming. Hundreds of emails to wade through, multiple projects needing attention, and that nagging feeling of being completely out of the loop. But I love this job and it’s good to be back. I spent the last two weeks on vacation due to the birth of my son. Pardon while I put on my proud daddy hat and gratuitously post a picture or two of little David.   Now that I’m back from my short hiatus I thought I’d give you a preview of...

    Grouping data in the RadGridView for WPF

    When you first add the RadGridView to your WPF application you will undoubtedly notice the section at the top of the control which I have outlined in red.  This area is officially called the GridViewGroupPanel, but I am just going to call it the Group Panel to save myself some typing.  The Group Panel allows the user to drag and drop column headers into the panel in order to group the data in the RadGridView at runtime.  Below you will see that I have grouped my data by the "Make" column in my grid of vehicles. Additionally, the sort order of...

    Reporting: How to set default value for a multivalue parameter

    Generally when you want to set a default value for a parameter, you use the Value property of the parameter (this.ReportParameters["MyParam"].Value), but what to set when you want all values to be selected by default  i.e you have a multivalue parameter? You can do that by providing an ArrayList containing all your values to the report parameter Value property. For consistency of the Tips & Tricks series, I am going to use the project from the Using Report parameters UI to sort by column blog post. Let's make the SortByColumn parameter accept multivalues by setting the MultiValue property to True. We...

    RadControls for WinForms and Windows 7 beta

    A couple of days ago I finally managed to get my hands on the latest hype, Windows 7, and to give it a spin. The first impression I got after installing the new OS went to the performance improvements it offered – it felt better than Vista, and the boot up time was really impressive. Then came the appreciation of the UI improvements which seem to be a natural evolution of the features Vista introduced. Win7 goodies aside, I am happy to say that RadControls for WinForms run perfectly fine on the beta – there are no hiccups, messed layouts...

    Master/Detail with RadGridView for WPF using ObjectDataProvider and ADO.NET Entities

    In my previous post, I showed how to instantiate LINQ to SQL DataContext using ObjectDataProvider in WPF. With ADO.NET Entities you can do something similar: <Grid.Resources> <ObjectDataProvider x:Key="customers" ObjectType="{x:Type local:NorthwindEntities}" MethodName="get_Customers"> </ObjectDataProvider> <ObjectDataProvider x:Key="orders" ObjectType="{x:Type local:NorthwindEntities}"...

    RadComboBox and ASP.NET AJAX 4.0 Preview &ndash; using client-side templates and webservice load on demand

    Edit: The following content applies to ASP.NET Ajax 4.0 Preview 4. Download the project that uses the latest MS Ajax 4.0 Preview 6 from Here Many of you have asked us, the ASP.NET support officers, whether RadComboBox supports templates when bound to WebService. Using the latest official .NET Framework (3.5) the answer was ‘no’. Fortunately, this is possible with the client-side templates introduced in the next version of the .NET Framework – 4.0. Currently it is in a Preview stage and you can find its roadmap here.  We have already demonstrated how to use the new client-side templates in RadTreeView and RadGrid.
