RadPivotGrid’s development is gathering momentum and Q3 brings along a major improvement: our pivot grid control for Asp.Net Ajax already comes equipped with a powerful filtering mechanism. Let’s look straight into what this new feature offers. Filtering in RadPivotGrid supports three modes: report, label and value. 1. Report filters Report filters are applied on fields that do not participate in the grouping of the data but are still present in the underlying data source:   So, for example, let’s suppose that your data items grouped by RadPivotGrid feature a Category property with 100 unique values. Furthermore, your manager needs a report where the data should be grouped...

A few months ago, I blogged about Telerik’s ASP.NET RibbonBar control (or just ribbon for short) in general: why use it; a few words about the ribbon spec; improvements we have made and future plans we have for it. Now, few days after the 2012 Q3 release, I am blogging about our progress in this area, as well as bringing up some other lesser known features of the ribbon. What's old new in the Ribbon I did mention this in my previous post, but perhaps I did not emphasize it enough: apart from complying with the MS specs more, we introduced two major features for...

It is only a few days since the 2012 Q3 release of RadControls for Silverlight and WPF and we have something new to show you. Here in Telerik we really appreciate feedback from you, the customer. Following this feedback we revamped our ChartDataSource to include the most desired features and we also significantly improved performance. Let’s start with a few words on the ChartDataSource itself. If you are familiar with it you can safely skip this section and move directly to the goodies. The ChartDataSource is a companion control, designed to work together with our new charting solution –...

Unit tests are most effective when the System Under Test is isolated from its dependencies.  The best way to isolate your code (and make your code more SOLID) is through dependency injection. But even if you follow the rules of SOLID and inject all of the necessary dependencies in as interfaces, you are still faced with the fact that you depend on them. In order to test your code, something concrete has to be passed into the code in order for it to even compile.  Your production code will most likely use a factory to create concrete instances of the dependent interfaces, but that...

Since we introduced the RadPivotGrid for ASP.NET AJAX in Q2 2012 we have been working hard to bring new functionalities and make our next grid control the best on the market. Now with the release of Q3 2012 we are happy to tell you that we are even closer to achieve desktop-like experience in the browser. The new Telerik’s PivotGrid ConfigurationPanel is a perfect showcase of what RadControls could do and how the web could encapsulate rich client-side interactions with heavy CPU intensive backend calculations. Let’s go through the details.
