Possible to have panels as User Controls?

Question

Hello,

I have a form that deals with customers applications. The form splits in two panels. First panel is common for all applications (has to do with application number, application date, personal statement etc), second panel though is according to Application Type (Application Type is a combobox which being filled in the first panel). So, according to the application type value a different panel has to be called.
Is is possible to build panels as User Controls and call them when are needed instead of having 10 different panels loaded invisible all the time.

I'm looking forward hearing your opinions on this.
