The role '' is not found - error message

 Everything in the function below works as I would expect until  line 14 where it says they role "" was not found, even though debugger clearly shows that therole paramater is set to "admin" on the function call.

I was not having this problem until I made the switch from a mdb role data base to running the aspnet_regsql util to insert all the tables and sprocs into the normal database, but I have double checked and everything seems fine below.

Thanks for the help

It seems that the reason is that it is re-creating the mdf database file when it is called on, and then in the newly created file the roles (admin, etc) do not exist.

After adding a provider element to the roleManager in the web.config everything seems to be working now just fine (in case anyone has the same issues)

 

        <roleManager enabled="true"
                                    defaultProvider="MyRoleProvider"
                                    cacheRolesInCookie="true"
                                    cookieName=".myroles"
                                    cookieTimeout="30"
                                    cookieSlidingExpiration="true"
                                    cookieProtection="All">

            <providers>
                <add name="MyRoleProvider"
                         connectionStringName="MyMembershipConnStr"
                         applicationName="**your_app_name"""
                         type="System.Web.Security.SqlRoleProvider" />
            </providers>
            
        </roleManager>
