Did you know that you can add Telerik Silverlight Charts to your ASP.NET applications?

RadControls for Silverlight


  • This example shows RadChart and RadTooltip integration. RadChart creates image maps, all you need to do is provide the corresponding values to the properties of ActiveRegion object. This example shows setting ToolTip property in ItemDataBound event  handler. RadTooltipManager control provides the means to easily enhance existing tooltips.

    ItemDataBound event is fired for each ChartSeriesItem allowing customization for individual items. Note the difference in the tooltip content for items with values less than 10 and more than 30.
