Gets or sets a value that indicates whether to output the image map.

Syntax

Visual Basic (Declaration)
Public Overridable Property RenderMapArea As Boolean

Visual Basic (Usage)	Copy Code
Dim instance As FpChart Dim value As Boolean instance.RenderMapArea = value value = instance.RenderMapArea

C#
public virtual bool RenderMapArea {get; set;}

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.

C#	Copy Code
FpChart1.RenderMapArea = true; FpChart1.HotSpotMode = HotSpotMode.PostBack; protected void FpChart1_MapAreaClick(object sender, MapAreaClickEventArgs e) { HitTest hitTest = this.FpChart1.HitTest(e.MapAreaInfo); this.Label1.Text = hitTest.ToString(); }

Copy Code

FpChart1.RenderMapArea = true;
FpChart1.HotSpotMode = HotSpotMode.PostBack;

protected void FpChart1_MapAreaClick(object sender, MapAreaClickEventArgs e)
{
HitTest hitTest = this.FpChart1.HitTest(e.MapAreaInfo);
this.Label1.Text = hitTest.ToString();
}
