I'm not sure the best way to explain this but I want to take results from a stored procedure and list them but not in a grid. I am listing user profiles and I want to display a picture, name, description and other info from each record. But I want each in a group. How is this done in asp.net?

I have a ASP.NET Website project and I need to list all the users and their groups on my Windows system. I have set the identity impersonation to true and provided the username and password of the admin in the web.config. Where do I start?
Update:
I have the following code at the moment -
var machine = new DirectoryEntry("WinNT://<IP ADDRESS>");
foreach (DirectoryEntry child in machine.Children)
{
// get the child's group(s).
}
When I debug, I can see the list of users in machine.Children. How do I find the group(s) that this user belongs to?
I am "DomainMyDomainUserName" If I do this:
[Code]....
I can access the website I've created on my local machine in debug mode; and with my domain account as a local administrator, if I do this:
[Code]....
I can still access the website; and with my domain account in a Domain Group named "DomainDomainLocalSecurityGroup", if I do this:
[Code]....
I can still access the website; HOWEVER, if I create a Local Group on my machine named "LocalMachineGroup" and I add "DomainMyDomainUserName" to this group and I do this:
[Code]....
I get an Access Denied error trying to access the website. What I want to do is, have a group on my local machine (for testing), on a test web server, and on a production web server named "MyWebsiteUserAccess" with the same Domain Group (filled with Domain Users allowed access to the site) in all of these local groups; so that when I test the web application on my local machine, on my test web server and on my production web server, I don't have to change the Web.config file to have it work on each AND if the Domain Group name ever has to change, it won't affect access to the website.
What am I overlooking or is this even possible to do this way? I understand that there is a way to do Role Management through ASP.NET but I don't understand that well enough yet to implement that (and will probably go that route once I've done the research on how to best implement it for purpose of access control of this intranet site).
In C#, how do i access Active Directory to get the list of groups that a certain user belongs to?
The user details are in the form:
"MYDOMAINmyuser"
I've been following the instructions from here but they only work if i have the user details in the form:
"LDAP://sample.com/CN=MySurname MyFirstname,OU=General,OU=Accounts,DC=sample,DC=com"
So maybe what i'm asking is, how to get from the first, shorter, form to the fully qualified form below?
I have a user that when I attempt to enumerate her groups using either System.Security.Principal.WindowsIdentity.GetCurrent().Groups on user's computer
or System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups on the IIS server, I get a list of their old groups, not their new. I have checked the DC that they authenticate to and the ASP.NET page is running inside a SharePoint instance so the LogonUserIdentity most like is being provided from there Kerberos ticket.
Should I be looking up the groups directly from the AD instead of relying on the WindowsIdentity or LogonUserIdentity?
i have a code to get the groups a user belongs to.
try
{
DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName));
DirectoryEntry user = adRoot.Children.Find(completeUserName, "User");
object obGroups = user.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
{
// Create object for each group.
DirectoryEntry obGpEntry = new DirectoryEntry(ob);
listOfMyWindowsGroups.Add(obGpEntry.Name);
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex);
return false;
}
the above code works fine when i have to find the groups of a local user but
for a domain user it returns a value "Domain User" which is kind of wierd as it is a part of 2 local groups.
Research
I did some finding and got that i am being returned the primary group of the domain user
called "Domain User" group
but what i actually want is the groups of the local machines the domain user is a part of... i cannot get that.. any suggestions
another code using LDAP
string domain = Environment.UserDomainName;
DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
DirectorySearcher search = new DirectorySearcher();
search.SearchRoot = DE;
search.Filter = "(SAMAccountName=" + completeUserName + ")"; //Searches active directory for the login name
search.PropertiesToLoad.Add("displayName"); // Once found, get a list of Groups
try
{
SearchResult result = search.FindOne(); // Grab the records and assign them to result
if (result != null)
{
DirectoryEntry theUser = result.GetDirectoryEntry();
theUser.RefreshCache(new string[] { "tokenGroups" });
foreach (byte[] resultBytes in theUser.Properties["tokenGroups"])
{
System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0);
DirectorySearcher sidSearcher = new DirectorySearcher();
sidSearcher.SearchRoot = DE;
sidSearcher.Filter = "(objectSid=" + mySID.Value + ")";
sidSearcher.PropertiesToLoad.Add("distinguishedName");
SearchResult sidResult = sidSearcher.FindOne();
if (sidResult != null)
{
listOfMyWindowsGroups.Add((string)sidResult.Properties["distinguishedName"][0]);
}
}
}
else
{
new GUIUtility().LogMessageToFile("no user found");
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user.
return false;
}
this works too but i get the same result "Domain Users" . Please can some1 tell me how to get the local machine groups...?
This is how i have it setup:DAL: a dbml file for the contextBLL: All my BL rulesTypes: I made type for every object that i return to my presentation layer.Now that i made types and use this structure i find it hard to understand how to manipulate data. Normally i could just bind my datacontext to a grid and just activate all the datagrid's possibilities without having to worry about anything. for example when i want to enable sorting, i have to write my own logic to return teh right rows to the grid etc.
I have a multiview with two datagrids. The first datagrid is an overview grid and has an option to select an entry. When i select the entry i switch to my second view and I want to show the details for the selected object there.However... I bound a List to the first grid and now I don't know how to find out what entry is selected. I have an event handler for the SelectedIndexChanged.
I'm using the GetOleDbSchemaTable to get column info from an access db, column_name and description, but getting an error that the bind statement can't get the properties. I know its there because I can response.write it from its table, schemaTable.Rows(i)!DESCRIPTION.ToStringdo I have to bind it differently than when binding actual data from a table using the column name for reference?System.Web.HttpException: DataBinding: 'System.Data.Common.DataRecordInternal' does not contain a property with the name 'DESCRIPTION'.

View 1 Replies'm using a textbox to get the first 5 letters of the name.
An sqldatasource then finds the people who have names > than the five letters and picks up their ID numbers as well as their names.
After that I use a second sqldatasource to get one individual from that dropdownlist's persons name and id number and then using a detailsview I display that person.
Well both sqldatasouces work fine but it just does not pass the ID number when I debug it.
I'm building an ASP.NET MVC 2 site where I'm currently implementing an OpenID sign-up form. Unfortunately, I'm foreseeing a possible security bug/vulnerability inside my architecture.
Here's how I want OpenID login to work:
User requests /Account/Login, Controller sends back OpenIDLogin View. User enters their OpenID into the View, then OpenID authorization takes place, and finally the OpenID is returned to the Controller.The Controller checks whether the OpenID is currently in use by a user in the system or not. If it is, the user is logged in to that account. If not, the registration process begins.
And now, the OpenID registration process:
The OpenID identifier, as well as any other information provided by the OpenID provider (such as email address or name), is put into my custom ViewModel and sent to my OpenIDRegistrationForm View.The RegistrationForm View stores the OpenID in a hidden field to make sure that it gets sent back to the Controller.The user fills in the RegistrationForm View and sends it back to the Controller.The Controller creates the user account and puts the OpenID into the database.
The bug that I see within my architecture is that a user could modify the hidden value in the RegistrationForm View. Thus, they could spoof their OpenID! I will make sure to add another round of checking to the final Registration Controller Action to make sure that the OpenID that is provided doesn't exist yet, but there is still a possibility for spoofing. Can my architecture be improved somehow? I don't want this to end badly...
One solution I'm considering is encrypting the OpenID before I send it to the View and then decrypting it when it reaches the Controller. Should I try this?
I am using a grid control from ComponentOne and I had asked their support how I can call a VB code routine when a row is clicked on. They said no such event is available but gave the following code below. In the code below it looks like they are calling the "alert('click')" code when a row is clicked for client side. Is this right? If so, how can I call a routine in the vb code with this? I know this example is C which I can change over. I need to get data from a couple cells on the row that they click and run some vb code.
Code:
> What event is fired when i click a row so I can run code on the .vb code page? Such an event does not exist. You can handle a click on client side using RowCreated event handler:
void C1GridView1_RowCreated(object sender, C1GridViewRowEventArgs e)
{
if (e.Row.RowType == C1GridViewRowType.DataRow)
{
e.Row.Attributes.Add("onclick", "alert('click')");
}
}

View 5 RepliesI have to display about 1000 records in a list or grid.
Each row will have about 5 fields/columns,
eg.
empID
empName
empAddress

The list or grid must allow the user to select a row.
In addition, when a row is selected by user, the address will be shown under the list or grid.
We are in the process of migrating our current asp.net gridviews to silverlight grids. The challenge that I am facing here is that in the gridview, the grid is bind to a dataset/datatable. But in silverlight, I do not have dataset/datatable available in the silverlight class. So only option is to create a Webservice and convert the dataset that I am currently getting from business layer to a class that imlements IList<> (unless there are any other ways). Now to convert this dataset to Ilist, I have to loop through the dataset to load the List. In my current dataset I have almost 10,000 records or even more in some cases. So the response time will be really slow.Are there anyways to
1) Load the List from dataset directly without looping through ?
2) Fetch the data from database directly to a List without having loading the dataset ?
