5. Client Object Model

7. Equivalent Objects
Server .NET Managed Silverlight JavaScript
(Microsoft (Microsoft.SharePoint (Microsoft.SharePoint (SP.js)
.SharePoint) .Client) .Client.Silverlight)
SPContext ClientContext ClientContext clientContext
SPSite Site Site site
SPWeb Web Web web
SPList List List list
SPListItem ListItem ListItem listItem
SPField Field Field field

8. Getting Started: 3 things to know
• ClientContext is the central object
clientContext =
new ClientContext(“http://mysite”);
• Before you read a property, you have to ask for it
clientContext.Load(list);
• All requests must be committed in a batch
clientContext.ExecuteQuery();

9. High level handling of commands
Client Application Server
Sequence of Client.svc
commands:
command 1;
command 2; Execute commands
command 3; in the batch:
XML
context.ExecuteQuery(); command 1;
command 2;
command 3;
JSON
Process results Send results back

10. Client Object Model Limitations
• You must handle synch/update semantics in
code
• No elevation of privilege capabilities
• Requests are throttled
• .net CLR has sync method;
Silverlight CLR and Jscript are async
• Limited subset of Server OM functionality
• You only get what you ask for – nothing more
(but sometimes less)

11. .Net CLR Client OM
• Provides easy access from remote .NET clients
to manipulate SharePoint data
• Can be utilized from managed code – also from
office clients etc.
• Assemblies
● Microsoft.SharePoint.Client.dll (281kb)
● Microsoft.SharePoint.Client.Runtime.dll
(145kb)
• To Compare: Microsoft.SharePoint.dll –
15.3MB

13. Silverlight in SharePoint 2010
• Native Silverlight web part allows for compilation
and deployment of XAP-only solutions
• One-click deployment from Visual Studio 2010
• Web Parts can contain custom properties that
are sent to Silverlight via the InitParams property
• Abstracted visual design in Expression (make
the designer do it!)

14. Silverlight CLR Client OM
• Use the correct references:

16. Building and Deploying Silverlight
• Built in support in Visual Studio 2010
• Redirect assembly output into Module
• F5 deploy and debug experience
SharePoint WSP
Visual Studio

package on
F5 XAP

18. JavaScript Client OM
• Provides similar functionality to .NET/Silverlight COM from
JavaScript/ECMAScript
• Identical structure
● Initialize Context -> Specify Items -> Load Objects ->
Execute Query
• Limited to current site context (no cross-site scripting)
• Asynchronous (like Silverlight)
• Be aware of syntax changes
● get_web()
● get_lists()
● get_item()
