IMapTerritoryInfo.KeyAttributeName

Syntax

KeyAttributeName: String;

Description

The KeyAttributeName property determines the attribute name for a territory identifier display.

Example

Executing the example requires a form with the following components: the Button component named Button1, the MapBox component named MapBox1, and the UiMap component named UiMap1. UiMap1 is a data source for MapBox1. The map must be connected to the UiMap1 component.

The example is a handler of the OnClick event for the Button1 component.

Add links to the Drawing, ExtCtrls, Forms, and Map system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Map: IMap;
    TerrI: IMapTerritoryInfo;
    S: String;
Begin
    Map := UiMap1.Map;
    TerrI := New DxMapTerritoryInfo.Create;
    Map.View.TerritoryInfo := TerrI;
    TerrI.Layer := Map.Layers.FindByName("Regions");
    S := TerrI.KeyAttributeName;
End Sub Button1OnClick;

After executing the example the "S" variable stores the name of the attribute for the display of the territory info identifier.
