using asp.net membership api when I call Roles.GetRolesForUser(); it returns nothing. When I make a call Roles.GetAllRoles() all the roles are returned. What is the problem? Also what is the correct way to authenticate users using the membership api?
View 2 RepliesI have a section on a page where a user can change their username. This is basically the code for that:
user.UserName = txtNewUserName.Text;
user.Save();
user is a class in my dbml and Save calls SubmitChanges on the data context.The name is changed in the database, so when it calls the following method, it fails because it is trying to get the user with the old username instead of the one that is in the database now.
public override string[] GetRolesForUser(string username)
{
return dc.Users.Where(u => u.UserName== username)
.SingleOrDefault().Roles
.Select(r => r.RoleName).ToArray<string>();
}
Roles.GetRolesForUser(UserName) .I have follwing codes in my Web.config,
<authentication mode="Forms">
<forms slidingExpiration="true" defaultUrl="admin/Welcome.aspx" timeout="60"/> </authentication>
<roleManager enabled="true" defaultProvider="SecurityTutorialsSqlRoleProvider">
<providers>
<add name="SecurityTutorialsSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" applicationName="SecurityTutorials" connectionStringName="SecurityTutorialsConnectionString"/>
</providers>
</roleManager>
I'm new to WCF and this is definitely a rookie question. Why does my browser show/return nothing when I type this URL: http://localhost/service.svc/root, using the code below. I was hoping I would see an xml respone like: <double>56.78</double>. service.svc

I am using a script manager for ASP.NET MVC to combine and compact CSS files and JavaScript files for pages on a website. For the most part this works as expected, however there are times (couple of times per week) when the HTTP handler responsible for returning the content returns an empty response and so pages load without any CSS - the HTML returns and the images load as well. When this happens, refreshing the page does not resolve the problem, while resetting IIS always resolves the problem. Also, without resetting IIS, after some time the problem stops.
Normally the script handler logs errors, however there are no errors logged during the issue. It seems as if the handler is never invoked. There are no failed request logs generated by IIS.
I monitored resource usage when this was happening and did not notice anything out of the ordinary. The web server is running IIS 7 and has low CPU usage. I increased some parameters in IIS settings regarding the number of allowable requests to process, the problem still exists though perhaps less frequent. The website receives about 1.5 million pageviews monthly.

Ok, I almost hate to ask this because I'm sure it's been covered many times on this forum, but I'm starting to get too frustrated trying to get it to work, so I'm gonna ask anyway.I have setup forms authentication on my site and have it working without any issues. What I'm trying to do now is to add "Remember Me" functionality so that the users don't have to log in each time they access the site. I'm able to get the authentication part down, but the issue I'm having is that when the user logs in, I set certain attributes in Session variables for that user (name, site role, etc.). These values are obtained from a database after the user has been authenticated, based on the username. What I'm having problems with is getting at this username from the FormsAuthentication cookie.
After I authenticate the first time, I setup my cookie this way:
[Code]....
I have tried getting at the Username utilizing the User prinicipal, but it just returns blank.
I have a webapplication based on MonoRail, where we utilize the routing feature from MonoRail. On the first request after the application has started, the routing isn't initialized. To circumvent this, I have the following code in Application_OnError():
public virtual void Application_OnError()
{
if ( // identified as routing error )
Server.TransferRequest( Context.Request.RawUrl, false );
return;
}
Problem beeing that on our development server (which runs server 2008 R2, with IIS 7.5 and .NET 3.5) returns a blank page without headers, but on my workstation (which runs win7, IIS 7.5 and .NET 3.5) it works fine.
What could be the cause of this? If the code in Application_OnError() throws an exception, what would be the expected output?
I have verified the following:
The access-log shows one entry, I'm not sure if a TransferRequest would show up as a second entry when invoked successfullyThe application actually do some work according to my internal logs, and it doesn't die since a subsequent requests works flawlessly (because routing will be active)
The GetRolesForUser() method in the RoleProvider takes the user login name and returns the list of roles for that user. But in my application this is not enough, I need a few more pieces of information to be able to get the user's roles. How can I get this extra information into the method? I have it in the Session, but I found out that Session is not available in the RoleProvider.
What I had in mind was putting this extra info in some class that extends MembershipUser, assuming I can get to it inside the RoleProvider. But I don't know how to create the CustomMembershipUser and make it part of the MembershipProvider. Is this even possible? The easy way out would be using cookies, but I'm trying to keep away from it.
Why there is no method to get user roles by their ID. I do not want to use name. So I'm just wondering do I have to write my own or somebody else already did it ?
View 11 RepliesI have built an asp.net web site with .net framework 3.5 and I am trying to avoid sending unncessary queries to my database in order not to have high server load. I have a login view in my master pages and it contains templates for anonymous users and members. To lighten my server load, I am using Sql Data Profiler and Database Tuning Advisor. I noticed that every page load triggers a stored procedure to get user role using
dbo.aspnet_UsersInRoles_GetRolesForUser stored procedure.
My question is that if it is necessary to check for every page load or I can store it somewhere and check later. is it Login View or Login Control sending queries? is it about access rules to member's pages? or is it because I used the login controls in my master page?
I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action.
[HttpPost]
public ActionResult Manage(ProductOptionModel DataToAdd)
{
if (!ModelState.IsValid)
{
return View(DataToAdd);
}
var ProdServ = new ProductService();
if (DataToAdd.ID != 0)
{
//Edit Mode.
DataToAdd = ProdServ.EditProductOption(DataToAdd);
ViewData["Message"] = "Option Changes Made";
}else
{
//Add
DataToAdd = ProdServ.AddProductOption(DataToAdd);
ViewData["Message"] = "New Option Added";
}
var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID};
return View(RetModel);
}
So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. I have debugged the code and checked that the RetModel variable is empty.
Let's say I have a rolegroup as follows:
<asp:LoginView ID="lvDoSomeStuff" runat="server">
<RoleGroups>
<asp:RoleGroup Roles="RoleOne,RoleTwo">
<ContentTemplate>
...
</ContentTemplate>
</asp:RoleGroup>
</RoleGroups>
</asp:LoginView>
Is there a way I can make it so that a user must meet RoleOne and RoleTwo to satisfy the RoleGroup? By default, if a user is in either of the two roles, they will be granted access. I know I can do this via the code-behind, but I'd prefer to be able to wrap some content template with this markup instead of having to wrap it in a panel and hide the panel programmatically.
i want to implement asp.net role provider to assign users over my LAN to roles and have my asp.net intranet app implement security based on roles.
i dont want to use VS to manage this with the built in tools but rather hand this off to users to manage themselves. i want an admin folder with a page(s) for admin roles to be able to create/edit roles and manage users in roles... this way an admin can add a domain user (MyDomainUsername) to a role such as ProojectManager or Tester or Developer... and users wont need to contact me for these tasks...
can anyone provide me a link (or some sample code) to some sample i can use to admin roles and users over a LAN in asp.net with c#?

Newb question: what is the standard practice for assigning roles to newly signed-on members. Is it usually manual or is there a way of automatically assigning roles. Being completely new to this, I am confronted by the issue of my site having three different roles that new members could fall into, but am unsure about how to assign each a role. I can't imagine having to go through the process manually if I have thousands of members.
View 6 RepliesI have run into a problem where I need to remove certain items from collections that seem to only have get all functions.
My Idea is to get the full collection and then remove the unneeded items. Then take that new collection and bind it to whatever I need.
For example How do I get all the roles except administrator?
Roles strRoles = Roles.GetAllRoles()
RoleList.DataSource = (Roles) roles; //Roles.GetAllRoles();
RoleList.DataBind();
or How do I get all users but say user123
MembershipUserCollection users = Membership.GetAllUsers();
UserList.DataSource = users;
UserList.DataBind();
I am trying to understand the best way of implementing a DropDownList in ASP.NET MVC 2 using the DropDownListFor helper. This is a multi-part question.First, what is the best way to pass the list data to the view?Pass the list in your model with a SelectList property that contains the dataass the list in via ViewDatHow do I get a blank value in the DropDownList? Should I build it into the SelectList when I am creating it or is there some other means to tell the helper to auto create an empty value?

View 2 RepliesI have a project which is developed by using VS 2003 with Framework 1.0.My project works very well while I am testing it on localhost.But 'sometimes' my application will appear blank page after click a save button in the production side(using IE 7).I set 'Try catch' into server codes to detect any error caused after users click save button. And they never see any error description page but 'sometimes' blank page.So I assume my server codes are safe.
View 7 RepliesI would like to create a completely blank aspx page, but I can't figure out how. When I open up Visual Web Developer 2010 Express, and I go to File -> New Web Site, I have a few options. When I choose the ASP.NET Empty Web Site, it does not give me any tools in the Toolbox on the left, so this is no good. But when I choose ASP.NET Web Site, it gives me this template and all of this other stuff. I dont need this 'Welcome to ASP.NET!' template. I'm thinking that I need to choose the Empty Web Site and then Add New Item, but what item? I'm lost!

I am trying to have a listview which will work like a table with paging. My problem is I need to be able to add more than 1 row at a time. ie I want to click "add new row" multiple times on the same page without the page changing and without the rows I'm adding going away.
Basically I need the user to still see the already inserted rows as well as the rows they are planning to insert on the same page. This would mean the page size is temporarily larger than it should be. The new rows would be added to the end of my data source when the user goes to another page or clicks a separate save button.
I've finally figured out an issue I'm have with a zip code field being entered in a text box of a details view in edit mode. I'm trying to understand why i have the issue though. I don't understand why it keeps occurring.his what happens with the zip code field. I've been able to make it reoccur numerous times. If the details view is put in edit mode and the record is updated with the original 5 digit zip code, unaltered in any way, my regular expression validator catches it and doesn't let the update happen. If I change the replace the 5 digit zip code with a new one the update goes through fine. This new value can be a different or the same 5 digits and the update will work. If I don't change the value at all though the update will not go through.
