Sets the attribute or variable containing the geometry layer identifier for the geometry being drawn.
Generators: Android, Apple
Controls: Grid (Control Type: Maps)
You have to complete this property of the Panel Grid whose Control Type property = Maps with the attribute or variable that determines the logical Geometry Layer. In other words, this attribute/variable is the one that categorizes and builds the logical group.
For example, consider the following Transaction object:
UrbanArea
{
UrbanAreaId* - Numeric
UrbanAreaGeo - Geography
UrbanAreaGeoLayerID - Character (it may be Numeric)
}
The UrbanAreaGeoLayerID attribute stores values like "BusWay", "BikeWay" and "Avenue". This attribute can be assigned to the Geometry Layer Id Attribute property in order to build logical Geometry Layers.
Then, the Location Attribute property has to be set with the UrbanAreaGeo attribute.
