I use the default DNN user management system to register users and create user groups etc.  Once a user logs in, I was wondering if there is any way to grab some existing user identifier for use in my home made modules?  In other words, say I want to pull data specific to User John (I store his data in a table along with 99 others and pull the data into a gridview).  Is there any existing perhaps session based user identifier that the default DNN users management system uses that will allow me to pull data based on User Johns User ID?

Thanks

Dave

Dave:

You can always use UserID without having to define anything.  It will be -1 if the user is not logged in.  If you need the rest of the user info after they login then the way you mention is the way to go.
