Dynamically Selecting Role in Membership Provider
===

I have 3 Roles in Membership Provider such as "PRINCIPAL", "TEACHER" and "STUDENT".
A single User may have both "PRINCIPAL" and "TEACHER" Role.
Soon after, That particular user (Who have 2 Roles) Logged In, I got Bind all roles in a RadioButtonList for that User.

Now, He want to select one Role after Logged In and My Home Page should be for that particular Role of that User.

How to assign Role for the User dynamically..?

Thanks,
Lena.
