BeginUpdate;
The BeginUpdate method stops map rendering.
The rendering can be resumed by calling the IMap.EndUpdate method.
Executing the example requires a form, a button named Button1 on the form, the UiMap component named UiMap1 that is a data source for the MapBox component. The map must be connected to the UiMap1 component.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
Map: IMap;
TerritoryInfo: IMapTerritoryInfo;
MapView: IMapView;
MapLayers: IMapLayers;
Begin
Map := UiMap1.Map;
MapView := Map.View;
Map.BeginUpdate;
TerritoryInfo := New DxMapTerritoryInfo.Create;
MapLayers := Map.Layers;
TerritoryInfo.Layer := MapLayers.FindByName("Regions");
MapView.TerritoryInfo := TerritoryInfo;
Map.EndUpdate;
End Sub Button1OnClick;
After executing the example the territory info of the Regions layer is displayed for the map. Map rendering is stopped to display the territory info.
