For each module I have created it's own role.

I have then created a new module that displays each role and allows the user to tick/untick the associated check box with each role.

When they click on save, I add any news roles and remove any redundant roles for that user.

However once I have done this, I wish to refresh the entire screen so that the changes are reflected immediately! - i.e. some new modules are displayed and others are no longer displayed depending on what the user has selected.

There MUST be a way of dynamically changing user roles at runtime without the user having to logout????????

So my question is how do I do this screen refresh?

I know all my roles are updated correctly (by running the GetRolesByUser method).
