FarPoint.Web.Chart Assembly > FarPoint.Web.Chart Namespace > FpChart Class : EnableClickEvent Property


Glossary Item Box

Gets or sets a value that indicates whether the Click event can be used.

Syntax

Visual Basic (Declaration) 
Public Property EnableClickEvent As Boolean
Visual Basic (Usage)Copy Code
Dim instance As FpChart
Dim value As Boolean
 
instance.EnableClickEvent = value
 
value = instance.EnableClickEvent
C# 
public bool EnableClickEvent {get; set;}

Property Value

true if the Click event can be used; otherwise, false.

Remarks

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.

Example

This example creates a chart control in Spread and maps several events.
