Public Property MapAreaAttributes As String

Visual Basic (Usage)	Copy Code
Dim instance As StripLine Dim value As String   instance.MapAreaAttributes = value   value = instance.MapAreaAttributes

public string MapAreaAttributes {get; set;}

Return Value

A value that represents the attributes of the chart element's corresponding map area.

The following sample specifies a client-side javascript function to execute when the user clicks on the first data element.

Visual Basic	Copy Code
Chart1.Series("Series1").Points(0).MapAreaAttributes = "OnClick = javascript:MyFunction()"

Setting this property will automatically result in a client-side image map being created, and a map area will be created with the attribute string appended to the <MAP> tag (that corresponds to the chart object this property is being set for).

Since the entire string is appended to the <MAP> tag multiple attributes should be separated with a space.

MapAreaAttributes can be used in conjunction with the Href property to specify map area attributes (e.g. Target= _Blank) as well as client-side event handlers (e.g. OnClick="MyEvent()").

Setting this property will have no effect if the Chart object's MapEnabled property is set to False (True by default).

IMPORTANT: To create an image map this way the RenderType property of the Chart object MUST be RenderType.ImageTag. It is possible to create an image map when using binary streaming, but another technique must be used. Refer to the Client-Side Mapping and Binary Streaming topic for further details.

Special keywords may be used when setting this property, and each keyword will be replaced with some type of data from the applicable chart element. Refer to the following table for a listing of all available keywords:

To create image maps that have user-defined coordinates use the MapAreas property of the root Chart object.

Refer to the Client-Side Image Maps topic for more information on how to implement client-side mage maps.
