Public Property Href As String

Visual Basic (Usage)	Copy Code
Dim instance As LegendItem Dim value As String   instance.Href = value   value = instance.Href

public string Href {get; set;}

Return Value

A value that represents the destination URL of a legend item. To use an absolute URL start the string expression with either "http://" or "www.". If the string does not start with either of these prefixes it will be treated as a relative URL.

Setting this property will automatically result in a client-side image map being created, and a map area will be created with the HREF attribute set to the specified anchor or URL. This map area will also use the dimensions that correspond to the relevant chart element. For example, if the HREF property is set for a data point then html code similar to the following will be generated at run-time:

<img id="Chart1" USEMAP="#Chart1ImageMap" src="ChartPic_000002.jpg?6735e83b-f0cd-4225-8be4-047695a61040" border="0" />
...
<MAP NAME="Chart1ImageMap">
<AREA SHAPE="rect" HREF="http://www.healthquotes.ca" COORDS= "69,120,106,309">
</MAP>

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.

Attributes of the map area(s) can be specified by using the MapAreaAttributes property (e.g. TARGET=_Blank).

This property allows you to set special keywords to display different types of Chart-related data. For more information, refer to the Using Keywords topic.

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.

Note: This property is applicable to the entire LegendItem.
