Count: Integer;
The Count property returns the number of attribute names in the collection.
Executing the example requires a form with a button named Button1, the UiMap component named UiMap1 and the MapBox component. The map must be connected to the UiMap1 component.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
Map: IMap;
Layer: IMapLayer;
S: Integer;
Begin
Map := UiMap1.Map;
Layer := Map.Layers.FindByName("Regions");
S := Layer.AttributeNames.Count;
End Sub Button1OnClick;
After executing the example the "S" variable stores the number of attribute names of the Regions layer.
