public event MapAreaClickEventHandler MapAreaClick
The event handler receives an argument of type MapAreaClickEventArgs containing data related to this event. The following MapAreaClickEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| MapAreaInfo | Gets or sets the MapAreaInfo indicates the event source. |
Each map area on the client side corresponds to a chart element (plot area, legend, series, etc...). The RenderMapArea property should be set to true to use this event.
The EnableClickEvent property specifies whether the Click event fires.
The MapAreaClick event fires if the RenderMapArea property is true and the EnableClickEvent property is false. If the RenderMapArea property is false and the EnableClickEvent property is true, only the Click event fires. If the RenderMapArea property is true and the EnableClickEvent property is true, the MapAreaClick event fires if the user clicks on a chart element. The Click event fires if the user clicks on the chart background.
The HotSpotMode property is used if RenderMapArea is true. HotSpotMode determines the behavior when the user clicks in a map area. The options are inactive, navigate, and post back. The inactive option is useful if you wish to display a tooltip in the map area. If the HotSpotMode is set to post back, the MapAreaClick and Client events are fired. If the RenderMapArea property is false, the HotSpotMode property has no effect.
