You have to pass the list or roles to FormsAuthenticationTicket

Here is the complete code, I have added comments as well.

protected void lbtnSignIn_Click(object sender, EventArgs e)
{
 .......Login credential checking code......
 .......If the use verified, then add the roles to FormsAuthenticationTicket 
 .......I am assuming in the below code, you are getting list of roles from DB in DataTable
 String roles = String.Empty;
 if (dtblUsersRoles.Rows.Count > 0)
    {
     for (int count = 0; count < dtblUsersRoles.Rows.Count; count++)
     {
      //build list of roles in comma seperate
      roles = roles + "," + dtblUsersRoles.Rows[count]["RoleName"].ToString();
     }
    }

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, txtUserID.Text, 
DateTime.Now, DateTime.Now.AddMinutes(30), false, roles.Substring(1, roles.Length - 1), FormsAuthentication.FormsCookiePath);
string hashCookies = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hashCookies);
Response.Cookies.Add(cookie);
}

then you can check the user, if he lies in certain role

 if (HttpContext.Current.User.IsInRole("Super Admin"))
 {
