How to design common page across different sub sites and make them customizable?

I have a requirement to develop common pages with web parts and all authoring capabilities that should be hosted in the top level site and can be shared among all sub sites. The advantage of this should be as long as the sub sites don't want to customize this common page for look and feel or authorizing content this page will be served as a common page and yields the performance benefits. But when the sub site wants to customize the common page, it will have its own copy and any changes made to the common page shouldn't be available for the customized common page. How can I achieve this? I tried with the application page by hosting them into the 14\TEMPLATE|Layouts folder, but couldn't see the publishing capabilities enabled. Help will be greatly appreciated.

Need help getting My Sites running


I am setting up a 3 server farm - two load balanced front ends and one app server.  All servers are Win08 R2 and connecting to SQL 08 R2.

I have done everything I've found to configure the MySites but they do not work.  When I attempt to connect, I get the following error:

User Profile Application Proxy failed to retrieve partitions from User Profile Application: Microsoft.Office.Server.UserProfiles.UserProfileApplicationNotAvailableException: No User Profile Application available to service the request. Contact your farm administrator.   

The user profile service is running, a profile sync has been run, and a profile exists for the account which I am using to authenticate.  A host site has been setup using the Enterprise My Site Host template and a service connection exists between the MySite and the Profile service app.  The app pool for the site is running under a sp10-mysite account which is in the local admin group of all three servers.  Self service site creation is on for the web app.

In the My Site Settings, I do not have a Perferred Search Center because I haven't set that up yet.  The My Site Host is set to the correct url (mysite...edu).  The personal site location is mysite...edu/personal and read permissions level includes All Users and All Authenticated Users.

SharePoint Tutorial - Team Sites

Team sites are small web sites that are created to store everything about a particular thing. For example a site can be created for a department in an organization like human resources. I site can be created for a particular project. A site can even be created for a meeting. Everything about the thing (department, project, meeting) like documents, lists, calendars, etc. is stored in that site.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Show grand total running total in GridView Footer

In many scenarios we need to display Running total as well as Grand total in GridView footer. In this post i will try to explain in an easy way that how we can display running total & Grand total in a GridView footer combindly. To explain this solution using an example here i use a sales order report. The report contains all sales order amount in a tabular way. I will use a GridView to display sales order amount and use GridView footer to display Running total & Grand total. Let we have a customer table with id and name column plus an orders table with OrderID,CustomerID,OrderDate & Amount. Now our goal is to show all customers order with amount as well as page wise running total & grand total. Note that running total is necessary when you enable paging in a GridView where as Grand total is always you can consider.

Client script not running


Dear all,

in my MVC 2 application, and in the shared Master Page I wrote this little script for menu handling :

<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript"> $(document).ready(function () {

             $('ul', this).slideDown(100);  
        function () {

The script, that shows menu items when the

Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!
