Client Object Model Architecture Sharepoint2010

The Architecture of Client Object Model, and understand how it functions,



As can be seen in the above diagram all versions of the Client OM go through the WCF Web Service namedClient.svc. This Web Service is located, along with all other SharePoint Web Services, in the folder [SharePoint Root]\ISAPI. The Client OM is responsible for packaging any requests into XML and calling the Web Server, however, when this call takes place is controlled by the developer as you will see. The response from the Client.svc Web Service is sent as JSON and the Client OM is responsible for transforming this into appropriate objects for use in the environment the call was made from.

   The SharePoint Client Object Model is supported in three environments; .NET managed code, JavaScript and SilverLight.

.NET Managed Code Assemblies

To use the Client Object Model in .NET Managed code you must add references to two assemblies in your Visual Studio project. Both of these assemblies can be found in [SharePoint Root]\ISAPI folder, which is typically C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\.

Microsoft.SharePoint.Client.dll (282kb)
Microsoft.SharePoint.Client.Runtime.dll (146kb)

As you can see from the indicated sizes these are not large assemblies and won't bloat an application very much. Despite their relatively diminutive size however they pack a great deal of punch, as you will soon see.

Silverlight Assemblies

Just like .NET managed code, to use the SharePoint Client OM from within a Silverlight application you must add two assemblie references. These assemblies are a little trickier to find and are located in the [SharePoint Root]\Templates\Layouts\ClientBin folder.

Microsoft.SharePoint.Client.Silverlight.dll (266kb)
Microsoft.SharePoint.Client.Silverlight.Runtime.dll (142kb)

The location is understandable considering the the Layout folder is mapped to each SharePoint Web Application and the heavy use of Silverlight within SharePoint 2010. You will notice the size of these assemblies is just slightly smaller than their .NET managed code counterparts. Despite this, there is no difference in functionality.

JavaScript code(ECMA Script) 

To make use of the Client OM in JavaScript you must include the SP.js file on the page. The corresponding SP.Runtime.js will be added automatically by SharePoint.

Hide the Recycle Bin & View all Site content links in SharePoint site?

Here is How in MOSS 2007: Just add the Content Editor Web part and place the below code ( Add it in Master page if you want to apply for all sites) :

<style>

  

.ms-quicklaunchheader{display: none;}

  

.ms-recyclebin{display: none;}

  

</style>

For SharePoint 2010, CSS classes are little different

/*To Hide both */

.s4-specialNavLinkList

{

display:none;

}

  

/* To Hide Recycle bin */

.s4-rcycl

{

display:none;

}

  

/* To Hide "All Site Content" */

#ctl00_PlaceHolderLeftNavBar_PlaceHolderQuickLaunchBottom_PlaceHolderQuickLaunchBottomV4_idNavLinkViewAllV4

{

display:none;

}

Want to Hide View All Site Content / Recycle Bin Links from everyone, except Site Owners?

Yes, You can set the permission string of these links to hide it from all users except the specified in PermissionString property.

Open your master page in SharePoint designer (either MOSS 2007 or SharePoint 2010). 

In Design view select "All Site content Link"

in Tag Properties, Go to PermissionString and Enter the permission string. Say, you want this link to be available only to Site owners, then enter: "FullMask"
