Dynamic Data And Real World User Admin Application?
Sep 3, 2010
develop a user admin application.My schema looks like the following:See full size As you can see I've got my own version of the user table and profile tables to store my data with a one-to-one mapping with aspnet membership tables.I'm interested in using ASP.NET dynamics to speed up the proccess of creating an admin system.
I would like to create a customised listing with a search and a data grid listing with just basic details such as name and state information, date registered and then when you click to edit your presented with the domain representation of the data and not the exact undelying data.Has anyone any experiece in doing this or building a real work application with Dynamic data?
Following is my case in detail.I have a class against which I will configure an objectDatasource(I have a datatable in the class which the data will be initially loaded from the database.)A gridview which has provisions to add/update/delete records will be bound to the objectdatasource
My methods i.e. insert/update/delete will be manipulating the datatable and NOT the database directly(I DONT WANT TO CONNECT TO THE DATABASE IN THESE STEPS. THE REASON IS THAT THE INSERTS/UPDATES/DELETES WILL BE PERSISTED ONLY WHEN THE USER CLICKS A SAVE BUTTON(MAY BE PLACED OUTSIDE THE GRID) . My class to which the objectDatasource points to will have anadditional AcceptChanges method which will be called on clicking the save button. This method is the one which connects to the database and where the adapter.update will be called.The query here is that how do I call the AcceptChanges method of my class instance which is bound to the grid? Also I would like to get some websites where I can see the real world implementations of gridview(with insert/update/delete options) so that I can improve my implementation.
I currently have a datagrid that has no columns, I generate a few column types on the fly using a column prefix. This enables a new dataset to generate a new datagrid, all is well, except...
1) Generating new datasets is beyond the skill of the admin, I could offer a set of options and dynamically create an SQL query/view to be saved in a datatable and retrieved by the querystring, but I'm not sure if there is a better way when I consider my next issue.
2) I want to be able to create an edit/detail page that is generated by a new query returning chosen fields, aliases for the field labels and field drop down options retrieved from the existing database and then positioning of the fields on the page set by the admin then stored as either field & coordinates or ? I'm hoping that there is a way to enable an admin to position the fields & controls either by selecing XY coordinates, then save it off as XML or similar to be reused as a template.
I'm trying not to re-invent the wheel and also keep my billable programming time to a minimum, but I'm willing to spend as much time researching & learning the techniques.
I'm trying to create custom control which displays real-time state (progress bar, or percent value) during time-consuming task (no animated GIF, or static text message).
This scenarion can't be done with standard UpdateProgress control, because it displays only static progress information.
This custom control can be then used as follows:
Aspx page should contain this custom progress control and a button.When user clicks button, page executes postback to the server.Server in button click handler starts performing some time-consuming task. Client installs timer with interval is set to 2000 ms.In client timer event handler should be request to the server for progress refresh.If server receives request from progress control, it checks actual task progress state, and performs client control refresh.When server terminates executing the task, it hides progress control on the client.
How can be this scenarion accomplished? How can I create such custom control?
I have a project That Is Some Ebooks project..,I want to create a dash Board,If User Register then he Login To Dashboard and he will upload some books in his admin panel..,if new user register then how to create a other Dynamic Panel..Each Admin Panel for Each User..dynamic Panel..how to create it..?
I found a great answer on SO describing how to set up custom user roles, and I've done the same in my project. So in my Login service I have:
public ActionResult Login() { // password authentication stuff omitted here var roles = GetRoles(user.Type); // returns a string e.g. "admin,user" var authTicket = new FormsAuthenticationTicket( 1, userName, DateTime.Now, DateTime.Now.AddMinutes(20), // expiry false, roles, "/"); var cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(authTicket)); Response.Cookies.Add(cookie); return new XmlResult(xmlDoc); // don't worry so much about this - returns XML as ActionResult } And in Global.asax.cs, I have (copied verbatim from the other answer): protected void Application_AuthenticateRequest(Object sender, EventArgs e) { var authCookie = Context.Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { var authTicket = FormsAuthentication.Decrypt(authCookie.Value); var roles = authTicket.UserData.Split(new Char[] { ',' }); var userPrincipal = new GenericPrincipal(new GenericIdentity(authTicket.Name), roles); Context.User = userPrincipal; } } Then, in my ServicesController class, I have: [Authorize(Roles = "admin")] //[Authorize] public ActionResult DoAdminStuff() { ... }
I login as a user with the "admin" role, and that works. Then I call /services/doadminstuff - and I get access denied, even though when I put a breakpoint in Global.asax.cs, I can see that my roles do include "admin". If I comment out the first Authorize attribute (with roles) and just use a plain vanilla Authorize, then I can access the service.
I need to add a "real-time" element to my web application. Basically, I need to detect "changes" which are stored in a SQL Server table, and update various parts of the UI when a change has occured. I'm currently doing this by polling. I send an ajax request to the server every 3 seconds asking for any new changes - these are then returned and processed.
It works, but I don't like it - it means that for each browser I'll be issuing these requests frequently, and the server will always be busy processing them. In short, it doesn't scale well. Is there any clever alternative that avoids polling overhead?
This is what I have in the RegisterUser.aspx and yet when the admin registers a new user, then on clickiing the register button, the site logs in as the user who was just created.
I have an asp.net application which uses session for user management. So if the application is restarted users will loose their works. I have some components used by this asp.net application and those components (class libraries in Bin folder) have configurations. I want to save configurations of those components somewhere and change them from back-end (administration panel) and the components use the updated configs but still application should not be restarted (changing web.config will result in application restart).
In our project, we have a situation where the administrator needs to 'force log off' a particular user under certain conditions. In other words, the admin user needs to have the ability to kill any other user's session.Is this possible? By using the session properties, we can kill the current session (the current user's session) but is it possible (for the admin user) to kill some other user's session?
I am currently trying to figure out how to best go about implementing an administration side for my application.I have a user site, where users can log in, customize their profile, submit information etc.I would like administration users to be able to log in and be able to choose from a list of users. From there, the administrator can submit information for the user just like the user can.
How should my pages be laid out?How should the Web.sitemap file look? Is there a nice way of creating a sitemap (maybe in memory?)Would this method have to use session variables?
have table for users have a some attribute one of them admin attribute have a bit data type when the user is admin it is true and i have ligin page and control panal page i want throw login page check for the user to redirect him to control panal if the user is admin the control panal will be displayed with moreoptions any one how can i doing this with select statement
i am currently checking to see if the logged in person is an admin, by putting a check in the page_load function. (same thing to see if the person is logged in at all)
is there a better way to do this? or should i just go ahead and put my check on every single page?
I am creating a web application using Form Authentication of Asp.Net with C# and back end Sql Server. Here in my application administrator login and creates new users. I am using the create user wizard under login controls. My problem is when the new user is created by Admin he is automatically logged out and logged in with new user credentials which he has just created.
I have master page concept in the project where as i am trying to create the export function in the child contrl.on the button click i wrote the below code
I'm using DataAnnotations to validate creation of a new Admin user. However on EDIT page I want to have password and confirm password fields blank. This way i know that password has not changed. However whenever I EDIT a user I get ModelState.IsValid = false because password and confirm password are blank even though I set these in my controller. how would i fix this so that on EDIT screen I can omit "Required" validation?
I am using SQL membership authentication and SQL Database for my ASP.NET Website and its using for my Organization (has multiple Branches in different cities).How I can get all user list which are recently online/Login in my system (WebSite) in my Admin Panel?
In my project I have one folder called Administration (contains pages created for administrating the public part of the page) and in root I have public pages. What I want to do is to prevent anyone beside administrator to enter the Administration part and to make the Administration/Login.aspx default page for entering Administration part. This part makes me confused. I tried to create the access rules, but that wasn't the option because I upload the images to the Administration/Upload folder so if I deny the users the images on the public part can't be accessed.
The second problem I don't know how to solve is public part of the page where I want to allow commenting only to logged in users (users only, not the admin). How to check if user is logged in and authetificated and how to enable the commenting part of the form to him (textbox and submit button).
I have a directory structure root->admin-> admin operations admin page inherited from a ase page with principla security.demand role = "Admins" i am usinf forms authantication mode. i have also put a web.config file in admin folder, restricting other users. it is working normaly with siteroot/admin. I want to setup a mechanism to admin like siteroot/username/admin I can redirect to page admin but it gives security error, it should redirect to login page instead of if user did not sign in.
I am looking for a way to distroy the ASP.net membership session for a specific user. The reason I am doing this is as an admin I want to delete a user. This works fine, but if the user already has an active session, he is still marked as "online" until this session dies (I verify each time by using Current.User.Identity.IsAuthenticated). How do I go about killing a session based on the user it's authorized as. This way when I do Memberships.DeleteUser(username) I can also do Sessions.KillByUser(username)[URL]
I have an Admin folder which contains 4-5 aspx pages. I want to that only user with role="admin" can view those files. What settings i need in web.config?
