Roles not updating

Posted By:      Posted Date: August 24, 2010    Points: 0   Category :ASP.Net

I have all my code in my other post about checkboxlist issue, but it boils down to, once i find someone doing my search, it displays their permissions as checkboxes. But if i want to remove a permission and click update, the update doesnt seem to occur, if i search on myself, it returns me with my permissions already checked. I uncheck 1 permission, click update and the checkbox is checked again as the page posts.

Original Post:

My aspx page seems pretty simple:

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <div>Enter UserName: 
        <asp:TextBox ID="TxtUserName" runat="server" /><asp:Button ID="LookupBtn" runat="server" Text="Search" onclick="LookupBtn_Click" />  
    <div class="roleList">
        <asp:CheckBoxList ID="RoleList" runat="server" /><br />
        <asp:button ID="UpdateBtn" text="Update" Visible="false" runat="server" onclick="UpdateBtn_Click" />

My update button event and update method:

ASP.NET forms authentication with roles

Error when updating. Supposedly updating ID without being asked.



Server Error in '/' Application.

Value of member 'ID' of an object of type 'Ref' changed.
A member defining the identity of the object cannot be changed.
Consider adding a new object with new identity and deleting the existing one instead.

I get this error whenever I attempt to update an entry. Even an entry that has had nothing altered. I have tried to circumvent it but I think it must be a simple oversight. How could I have caused an ID update using the Edit.aspx page of dynamic data? Thank you in advance for the help!

Hard Code Roles on the Pages


If i hard coded role=Manager on the specific SiteMap/Folder/Page/etc. I will have problem when the manager need to remove from access a specific page. I need to change the code ont eh page/SiteMap/Folder more move the file into another folder.

What i have in mind is to change the role to taks oriented. such as role=AddStock, Edit Stock, Delete Stock, Print DO, Add Sales, Edit Sales, Deleted Sales..... (but it will be many role for 1 user compare to just 1 as Manager)

Will this cause performance issues later when each user have 60 roles and if i have 20,000 user will it affect the application performance?

Otherwise any other option? to make it flexible.

Timers: Implement a Continuously Updating, High-Resolution Time Provider for Windows


The timestamps that you can obtain from Windows NT are limited to a maximum resolution of 10 or 15 milliseconds, depending on the underlying hardware. At times, such as when you need to timetag frequent events, it is desirable to achieve a higher resolution. For example, what if you want to be able to contact a thread or perform some other task at intervals more frequent than 10 milliseconds? Suggested ways of achieving better resolution include using performance counters in conjunction with the sytem time to calculate smaller time increments. But using performance counters is a technique that presents its own problems. This article shows one possible way of overcoming limitations inherent in this approach.

BITS: Write Auto-Updating Apps with .NET and the Background Intelligent Transfer Service API


Both the .NET Framework and Windows have some very interesting APIs for creating applications that are capable of updating themselves automatically over a network. There are many advantages to writing your application to update itself like Windows Update does, including convenience for your users, from easier maintenance to network administration. Automatic updates require attention to factors such as discovery, security, and file replacement. In this article, the author covers the BITS API as well as a number of features of the .NET Framework that take care of these facets of auto-updating using the same facilities that the Windows Update uses.

How in web.config work in MVC



I would like to secure any URL below the http://MyServer/Admins and limit it to a specific role.

In webforms it was straight forward. I just put a child web.config in the /Admin/ folder and add <authorization>  <allow roles> tags to it.

How would be the equivalent technique in MVC?

Thank you,


Trying to get Roles to populate a checkboxlist based on tutorial and having issues.


I have been using the following tutorial and had to convert the code to C# for my project, now i cant get the code to work, im getting red line under the word "in" in the UpdateRolesFromList,
i tried to add a datasource on page load for the checkboxlist like so RoleList.DataSource = PopulateRoleList(User.Identity.Name.ToString());

and gives me error saying cannot implictly convert type 'void' to 'object'


What am i missing, that when i load the page or even do a search it never displays the checkbox list as it shows in the tutorial?

        protected void Page_Load(object sender, EventArgs e)

        public void PopulateRoleList(string userName)
            string[] roleNames = null;
            string roleName = null;
            roleNames = Roles.GetAllRoles();
            foreach (string roleName_loopVariable in roleNames)
                roleName = r

How to stop the repeated database queries for roles


Hello, friends,

We have a web application using VS 2008, c#. We try to filter siteMap nodes based on security roles. We have our customized the mether GetRolesForUser() in RoleProvider class to determine a user's role. In this method, roles will be returned by querying an SQL Server database.

However, we found that each time a page was loaded/refershed, this  GetRolesForUser() was called, and the database would be queried. This is too MUCH and expensive.

We thought the roles should be queried only once when a user logs in. After that, role info should be stored somewhere for this user, rather than query DB all the time.

Any ideas, reference paper, snipet,...,?

Thanks a lot!

Stored Procedures & SqlDataAdapter not updating a calendar control


Hi all,

I have a database linked to a calendar. I had a peice of code that retrieved dates from a database and populated the calendar. I wanted to tidy up my code using stored procedures (they seem neater & i assume there's a benefit somewhere). so i came up with this, however it's not working. The calendar displays, but it's not being populated with the database entries. The SqlCommand & SqlParameter I have working elsewhere in my code; as with the SqlDataAdapter (which also worked before i tried to conver to a stored procedure!) but combining these three (SqlCommand, SqlParameter & SqlDataAdapter) seem to be causing me problems.

It's probably something stupid but if someone could take a look and point me in the right direction, I'd be very grateful.


Public Sub dbConnection()
        dbConnString = ConfigurationManager.ConnectionStrings("connString").ConnectionString
        sqlConn = New SqlConnection(dbConnString)
    End Sub

        Dim dbCMD As New SqlCommand("PopulateCalendar", sqlConn)
        dbCMD.CommandType = CommandType.StoredProcedure

        Dim parameterBookedEvents As New SqlParameter("@bookedEvents", SqlDbType.VarChar, 50)

Adding user to certain roles


I have setup ASP security in my application. I used the following tutorial, just wondering if someone can tell me how i can setup this up to allow the creation of a user?


Can someone tell me where to find or what to search on to find some example of how to add the option for adding users?

I have the above setup and its working, but only because of the accounts i created with my global.asax file.
I need to give the admins access to add a new user. Currently i can search on existing users and update them, but need to add the ability to add a new user.

Sharepoint My Sharepoint Sites not updating.


The sharepoint My Sharepoint Sites list will not update.  It last updated with the results from 4/22/10. I determined that by looking in out Share Sevices Administration  database in the memberGroup table.  It shows current entries for everything prefaced by Mailto:   So the distribution groups are updating however, nothing is updating for the actual sites.  New sites have been added since this time and Membership in the Members group of these sites has  changed as well but none of these changes have been reflected i nthe My sharepoint sites.   These changes also do not appear in the My Memberships portion of someone's My Site.  Any suggestions?


We are running Sharepoint 2007 SP2 with W.S.S. 3.0 on a Windows srver 2003 R2 SP2 server.    No changes were made to the system on the date in question.  Perhaps 3 new team sites has been added in the days leading up to the problem. 

We see no errors in any of the timer jobs or the event logs that appear related to the issue.



Personal view reverts back to default after updating properties of item


I am working with a company that has 1 site collection with several sub sites.  I have built 3 document libraries with workflow in 3 different sub sites and all behave as expected.  I have one site where ALL libraries do something perplexing;

If you are in a custom personal view and you go into the properties of a document and then exit (update or not, does not matter) it reverts back to the default view of that library. 

Has anyone seen this?  is there an option when creating an album that could cause this?

thanks in advance for any input on this odd issue.

Updating Task Lists and Form Libraries From Workflow Form


There are actually two separate (I think) problems here. The scenario: I used the SharePoint Designer 2007 to create a workflow attached to a form library. When a form is submitted to the library, a To-Do-Item is created on a task list. The To-Do-Item is initially assigned to a GROUP. A user from the group then selects the name of an individual from a choice list in edit item. This person now becomes the Assigned To for the task.

What is needed is 1) To update the Assigned To column of the Form library when someone in the GROUP assigns the task to an INDIVIDUAL; and 2) To have the Due Date from the submitted InfoPath form propagate to the task list.

I've tried having one workflow try to do everything and also having a secondary workflow set up on the task list to do the task assignment update but have not been successful in solving either issue. I don’t think that I am really understanding how to Define Workflow Lookup when not working with the Current Item. I know what fields I want but I don’
