During a recent webinar, a question was asked about whether you can create a half circle gauge.  I recently covered this in my “Introducing RadGauge for WPF” webinar, but thought it would be good to have a quick blog post as well.  Below you will see a RadialGauge which contains two RadialScales placed along the left and right of the gauge.  This is actually very easy to produce since the RadialGauge is simply a container, you can place a number of scales inside of the gauge.      Here is the XAML for the screenshot...

The XmlDataSource control is a data source control that presents XML data to data-bound controls. The XmlDataSource control can be used by data-bound controls to display both hierarchical and tabular data. The XmlDataSource control is typically used to display hierarchical XML data in read-only scenarios. Because the XmlDataSource control extends the HierarchicalDataSourceControl class, it works with hierarchical data. The XmlDataSource control also implements the IDataSource interface and works with tabular, or list-style, data.  Page developers use the XmlDataSource control to display XML data using data-bound controls. The XmlDataSource typically loads XML data from an XML file, which is specified by the DataFile property. XML data can also be stored directly...

I’m happy to announce two new episode of RadTips, a series of screencasts offering tips and tricks for using Telerik's RadControls. If you've missed previous episodes, be sure to check them out on Telerik TV. Each is only a few minutes long and covers a specific feature of the RadControls. Grouping with the RadGrid In this episode I show ASP.NET AJAX developers how to using the built-in grouping feature of the RadGrid.

  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...
