Remarks
An end-user is able to select some items of the ASPxClientWebChartControl at runtime if the WebChartControl.EnableClientSideAPI property is set to true. Handle the ObjectSelected event if you want to perform some specific actions when an end-user selects a chart’s elements, or if you want to disable the selection of particular elements. Note that the currently selected element of the chart can be accessed via the ASPxClientWebChartControlHotTrackEventArgs.hitObject and ASPxClientWebChartControlHotTrackEventArgs.additionalHitObject properties.
