I looked the MapCtrl and RendererList classes in the documentation. I think MapCtrl should be used for Windows Forms applications only.
We have used Map object as per Geobase help document. (Creating a Web Application)
Everytime when i click the "Zoom in" and "Zoom out" button the entire page has been refreshed. But, I want "Zoom in" and "Zoom out" working with out refresh.
If you want a smooth and fluid zoom in and out with your map you should increase your Zoom property value with small amount. The Zoom property sets the current zoom level and is a double so the value can be reasonably small (e.g: step of 0.01).
Dragging the map works in GeoStream and the desktop. You can see a demo of the desktop doing this in the MapExplorer application provided with the SDK.
GeoStream is part of GeoBase and the SDK license supports GeoStream so GeoStream will work for you. If you have a production license (RUNTIME) it might need to be modified for GeoStream, in which case your account marnager can help you, or mail gbsupport@telogis.com for further information,
