Every now and then we receive requests / inquiries which wordings may vary, but basically all come down to the same thing – my chart space is limited, how to optimize the content of the ChartArea so my data does not look so squashed? One possible solution that works in some scenarios is to hide the legend altogether. Today we will propose another option for those of you who are looking for a less “radical” remedy – display the ChartLegend as a ToolTip on demand. Actually, this is quite easy to achieve with the ToolTipService class provided by WPF /...

We all know that animations are making our applications look more slick. As Silverlight and WPF are platforms that have great support for animations, we want our Silverlight and WPF applications to be more animated and look better.     Today I will show you how to add animations support to the Telerik RadWindow control using one of the most powerful approaches in WPF and Silverlight for extending the functionality of existing components – the attached behavior. We will create two attached properties that take care to run the animations when needed. The good thing is that you can use this approach for...

With our Service Pack release coming soon, we introduce a complete change set for RadNumericUpDown both in Silverlight 3 and WPF that should resolve most of the little issues the Q2 version has. Even though we have introduced several minor breaking changes that are inevitable, we have taken a decision to include all these changes in our Service Pack release due to the increased demand for easy and simple input control.

As you may already know, since the invention of the chart control there are some cornerstone cases when most of the implementations do not perform well. One of these is the arrangement of labels on the horizontal axis and especially when placed in a limited space(overlapping labels). This problem is clearly visible on the image below: Several ways to work around this problem have been developed and during the last months we put efforts to implement most of them. Our recent Q2.2009 release of RadChart for WPF/SL offers the following AxisX properties: LabelStep - when set to n, this property will make only...

RadChart data binding provides a simple and consistent way for applications to present and interact with data. In many cases the data that you work with is a collection of objects and you need the UI to update automatically whenever the datasource gets updated. WPF and Silverlight provide a built-in implementation of a data collection that implements the INotifyCollectionChanged interface and achieves the desired effect. However, when you try to blend the ObservableCollection<T> implementation with some LINQ queries, the situation gets a bit more complicated and most probably the out-of-the-box result will not match your expectations. Let us take the...
