Var
Map: IMap;
Layer: IMapLayer;
Legend: IMapLegend;
Header: IMapLegendHeader;
Font: IGxFont;
Begin
Map := UiMap1.Map;
Legend := New DxMapLegend.Create As IMapLegend;
Map.View.Legend := Legend;
Legend.Visible := True;
Legend.BeginUpdate;
Layer := Map.Layers.FindByName("Regions");
Legend.Visual := Layer.Visuals.Item(0);
Header := Legend.Header;
Header.Color := GxColor.FromName("Red");
Font := New GxFont.Create("Arial", 15, GxFontStyle.Bold);
