Drill-Down
RadChart has been deprecated since Q3 2014 and is no longer recommended for use, as it does not support modern browsers. We strongly recommend using RadHtmlChart, Telerik's modern client-side charting component. To transition from RadChart to RadHtmlChart, refer to the following migration articles:
Explore the RadHtmlChart documentation and online demos to determine how it fits your development needs.
The drill-down is a specialized Image Map where the clicked area of the chart navigates to a view with greater detail. For example, the user may click on a series in the legend or a chart series item to reveal another chart with an expanded view of that series or series item. Drill downs are implemented using the ActiveRegion property (see Image Map for more information on ActiveRegion).
In a simple drill-down example the chart series item for one area of a pie chart can be clicked on to navigate to another page in the project. The example has two pages, default.aspx and InternetSalesDetail.aspx.On Default.aspx a Pie chart displays percentage of sales for Wholesale, Retail and Internet divisions of a fictitious company.
Clicking on the Wholesale slice of the pie navigates to the InternetSalesDetail.aspx page.
In a more complex scenarios you will need to communicate between pages using query strings, Session variables or by filtering database data. Use a Click event handler for the chart or a Click event handler of a specific ActiveRegion to setup the data selection for the detail web page before navigating to it.
