如何在ArcObjects中创建IDynamicDisplay对象?

首先,需要将IDynamicMap::dynamicpapenabled属性从Map对象设置为true。

IDynamicMap pDynamicMap = pMap as IDynamicMap;
pDynamicMap.DynamicMapEnabled = true

Best practices for using dynamic display

你必须连接一个事件处理程序

ESRI.ArcGIS.Carto.IDynamicMapEvents_Event dynamicMapEvents = dynamicMap as ESRI.ArcGIS.Carto.IDynamicMapEvents_Event;
ESRI.ArcGIS.Carto.IActiveViewEvents_Event avEvents = activeView as ESRI.ArcGIS.Carto.IActiveViewEvents_Event;
avEvents.AfterDraw += new ESRI.ArcGIS.Carto.IActiveViewEvents_AfterDrawEventHandler(avEvents_AfterDraw);
dynamicMapEvents.AfterDynamicDraw += new IDynamicMapEvents_AfterDynamicDrawEventHandler(dynamicMapEvents_AfterDynamicDraw);
