Hi,      I wanted to know how to implement role based security in asp.net 4.0, in detail. Like from Data base to UI. I searched in google, but I don't find any good article which explains in detail.

Please let me brief how I wanted to implement. On page Load, drop will be filled with all available roles, with list of all check boxes(basically it will equal to the no. of links on the left side tree) below, I will select required boxes and then save. If that particular user with that role logged in, then we will load only those links which this role is having  ( of course we will assign that user with the spefic role). Thanks in advance.
