通用步骤：
1. 从Web controls 开始
2. 访问resource manager
3. 找到resource
4. 决定Resource支持那个functionality
5. 执行functionality
访问Resource有三种方法:
1、从Web controls访问Resource
Dim resManager as MapResourceManager = Me.MapResourceManager1
Dim mapResource as IMapResource = resManager.GetResource(0)
2、直接从Page或者control访问
Dim resManager as MapResourceManager = Map1.MapResourceManagerInstance
Dim mapResource as IMapResource = resManager.GetResource(0)
3、先访问得到Map控件的Functionality,然后根据Functionality得到Resource
Datasources 和 Functionalities
访问Functionalities的两种方法：
1、直接从控件获得
2、直接从resource获得
Create Functionalities
