Computing Values in the RadGridView for WinForms
When working with data there are a number of occasions where you may want to calculate a value for display within a grid. Did you know you can do this within the RadGridView itself?

This may be a new column that you are adding to the grid to store the value or you can override the value of an existing column by setting the Expression property.

Performance Monitor using RadChart for WinForms
I have had a few people ask me about using the RadChart in the same manner as Performance Monitor (aka PerfMon).

There are a wide variety of counters available, from CPU utilization of process threads to how many times the .NET Garbage Collector has run. The counters PerfMon allows...

WinForms RadGridView's new clothes
In our latest release – Q1 2009 – we were focused mostly on addressing known issues and minimizing the memory footprint of RadGridView for WinForms. However, we managed also to steal some time and redesign all of RadGridView’s themes. Some optimizations in our TPF framework helped us with this task. One of the heaviest operations in GDI+ is clipping. We managed to remove the clipping where it wasn’t really needed. This way we achieved two goals with a single shot: first, we got a performance boost, and second, we achieved better graphics and smoothed edges when using shapes. Our new Desert...

Telerik RadControls Enable New Breed of WinForms Apps
We have done a lot recently to make it possible for a WinForms app to get closer to the new UX trends set by the great WPF and Silverlight technologies. I know it would be hard to convince you that, but luckily I happen to have a slick new WinForms demo app to help me in this endeavor. The new RadControls for WinForms QSF comes with an animated welcome screen describing some of the unique features of Telerik WinForms suite: The fisheye bar at bottom animates so smoothly, that anytime I run the app I just can’t help myself but play with...
