Today was my first attempt at writing tests for RadControls with Watir and was surprised how easy it is. I found over the internet a good article on how to test ASP.NET applications using Watir and also referred to the Hristo Deshev’s blog post about Automating Complex JavaScript-rich Controls with Watir. If you use the approach described in it and create a watir_telerik_extensions.rb file, you will be able to create tests very quickly. See below a few tests about RadMenu, RadComboBox and RadTreeView which I have created in minutes: 1. This is a RadComboBox test which opens the drop down ...

What better source for tips and tricks for your beloved Reporting product, than a blog spot right from the kitchen where the product is ‘mixed’. As of this post, we would like to start a small series of tips and tricks that make a developers’ life sweeter. We’re not going to discuss general topics, so if you’re looking for answers for one of those questions – please review our documentation and our forums.

As I mentioned in my previous post “UI Automation/Accessibility in Silverlight 2, tools and resources summary”, UIA Verify is one of the current options for UI Automation testing of controls and applications.

So I decided to describe the tool’s features briefly and I hope you’ll enjoy the tutorial. First of ...

Our insatiable commitment to deliver more than expected in every aspect of our products resulted in me being curious, if we are as flexible as we think and whether one can always achieve his goal be it out of the box or with custom solution using our API and other controls if necessary. Hmmm what could that custom solution be – how about a custom Toolbar for our web ReportViewer. For those of you, who are unfamiliar with our Web ReportViewer , here is a short description – it is designed to render Telerik Reports within ASP.NET projects and it has a toolbar that...

When you start playing with LINQ queries over sequences of elements (e.g. getting min / max value for enumerable source) sooner or later you will come across this one -- the InvalidOperationException (“Sequence contains no elements”). The problem occurs as by default queries like IEnumerable<T>.Min(…) and IEnumerable<T>.Max(…) do not play nicely if you try to execute them on an empty sequence and just throw the exception described above. Unfortunately these methods do not have a corresponding counterpart like Single(…) / SingleOrDefault(…) that is smart enough to query the sequence if it is not empty or alternatively use the default value without raising...
