I can create a calendar view in code, however I have as yet been unable to figure out how to change the "Default Scope" (this is the name that appears in the user interface when editing a calendar view). The options in the user interface are Day, Week, or Month - Month being the default. I'd like to be able to change the default to something else, Week for example, but I cannot figure out how to do it, other than using the user interface.
You can't do it through API. By sending RPC call to owssvr.dll is the only other way other than UI. For complete solution, visit this link -
