Creates a special URL to represent post back operation for use in image maps.
Normally, image map may act like hypertext links, that is, clicking on a hot spot will jump to another URL. The GetPostBackURL method can be used to create a special URL, so that clicking will trigger a post back operation instead. This will result in a WebChartViewer.ClickHotSpot
event being fired on the server side.
The URL generated by the GetPostBackURL method should be used as the URL argument of the various getHTMLImageMap methods (eg. BaseChart.getHTMLImageMap
, etc) for generating image maps. The query parameters in these image maps will become attributes of the WebHotSpotEventArgs
In addition to the query parameters in the image map, GetPostBackURL supports an additional parameter that will be become the "cookie" attribute of the WebHotSpotEventArgs
when the event is fired.
A special URL for post back operating. This URL should only be used as the URL argument of the various getHTMLImageMap methods.
