Setting up roles in ASP.NET webform-CodePudding

apologies if this question seems basic, but I am quite stuck despite alot of googling I am trying to setup an ASP.NET webform project to use roles, I am creating users using the following:

 protected void CreateUser_Click(object sender, EventArgs e)
    {
        var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
        var signInManager = Context.GetOwinContext().Get<ApplicationSignInManager>();
        var user = new ApplicationUser() { UserName = Email.Text, Email = Email.Text, FirstName = FirstName.Text, LastName = LastName.Text };
        IdentityResult result = manager.Create(user, Password.Text);
        if (result.Succeeded)
        {
           
            string code = manager.GenerateEmailConfirmationToken(user.Id);
            string callbackUrl = IdentityHelper.GetUserConfirmationRedirectUrl(code, user.Id, Request);
            manager.SendEmail(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\""   callbackUrl   "\">here</a>.");
           
            signInManager.SignIn( user, isPersistent: false, rememberBrowser: false);
           
            IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response);
        }
        else 
        {
            ErrorMessage.Text = result.Errors.FirstOrDefault();
        }
    }

I am struggling to setup the project to use roles and add them to the users, could anyone please direct me in the right direction? A lot of the information available online relates to MVC or .NET Core projects and I cannot seem to implement them to my webform project mainly due to my limited knowledge of .net (new to this). Much appreciate your help

Well, since database roles tend to be a "one time" setup, then I usually just directly open the table in edit mode, and add the few roles I want to use.

If you using SQL server, then just fire up SQL studio, and right click on the table, (choose edit 200 rows option). I then just type in the roles, and that is quite much the end of this.

And, if you using a "attached" database in which asp.net attaches the database (and I tend to only recommend this for development), then view/display the database exploer, and the "view" data option ALSO allows you to edit.

Hence, you see this:

So, we just opened the roles table directly, and then I just enter the few roles I need/want.

So, say now this:

As for the "id", I just again manually type in 1, then 2 and so on. I can't recall ever having more then about 5-8 roles anyway, so it not a big deal, and in 99% of cases not worth the time to write code to add roles to the database.

However, you can add roles this way:

vb:

    Dim strRole = "ZooRole"
    Using context = New ApplicationDbContext()
        Dim MyRoleStore = New RoleStore(Of IdentityRole)(context)
        MyRoleStore.CreateAsync(New IdentityRole(strRole))
    End Using

var strRole = "ZooRole";
using (var context = new ApplicationDbContext())
{
    var MyRoleStore = new RoleStore<IdentityRole>(context);
    MyRoleStore.CreateAsync(new IdentityRole(strRole));
}

So, its rather easy to add some roles. Once of course you have the roles you want "defined" and added to the database, then you can/should be able to use the built in methods to add a new user to a role.

It is not clear if you issue/challenge here is adding/creating some new roles, of which THEN you can create users, and then add users to some defined roles.

So, trouble adding users? Trouble adding Roles? Trouble adding users to a given role? Which task?

In fact, during testing, I often have opened the above tables mannually, and simple edited the data by hand. (often, this becomes a chicken and egg issue. If I have a page setup to add/select users and assign roles, I can't get to that secuired page! (might have a role called "SiteAdmin". So, I often will just edit manaully my roles table (add a SiteAdmin), and add myselft to the "SiteAdmin" role.

it is actually quite easy to add some roles to a existing user manually as per above (ie: open the role table and add a few roles, and then open the AspNetUserRoles table and add myself to the SiteAdmin role (or whatever role you cooked up and floats your boat).
