PolygonHotSpot::Coordinates Property
A string of coordinates that represents the vertexes of a PolygonHotSpot object.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System::String^A string that represents the coordinates of a PolygonHotSpot object's vertexes.
Use the Coordinates property to specify the coordinates of the vertexes of a PolygonHotSpot object. A polygon vertex is a point at which two polygon edges meet. The string that you specify must be formatted with each coordinate separated by a comma. Each vertex that you specify must have both an x- coordinate and a y-coordinate. For example, the string "128,185,335,157,510,224,510,383,228,383" defines a polygon hot spot with five vertexes. The x-coordinate of the first vertex is 128. The y-coordinate of the first vertex is 185.
The following code example demonstrates how to programmatically create a PolygonHotSpot object and add it to an ImageMap control. The Coordinates property is used to specify the coordinates of the vertexes of the PolygonHotSpot object. The ImageMap control contains two other PolygonHotSpot objects that have been added declaratively. Each PolygonHotSpot object represents a geographical region on the map. When the user clicks a PolygonHotSpot object, it posts back to the server and the type and name of the hot spot are displayed in a label.
