VEShape.SetZIndex Method

You are not viewing the latest version of the AJAX control. Bing Maps AJAX V7 is the recommended JavaScript control for Bing Maps. If you need this documentation, it is available in as a CHM or PDF download.

Sets the z-index value for a shape.


VEShape.SetZIndex(icon, polyshape);

Parameters

Parameter Description

icon

Optional. An integer specifying the z-index for the shape's icon (or for the pushpin if the shape is a pushpin). If this value is null or undefined the z-index is not changed.

polyshape

Optional. An integer specifying the z-index for the shape. This parameter is ignored if the shape is a pushpin. If this value is null or undefined the z-index is not changed.

Although both parameters are optional, at least one parameter must be supplied.

Z-indices define the order in which items are drawn. Shapes with higher z-indices are drawn on top of shapes with lower z-indices.

All shapes have the same default z-index. 1000 for icon and 50 for polyshape. The following table lists the z-indices for most objects.
