Building dynamic applications with the share point client object model

This document provides an overview of building dynamic applications using the SharePoint Client Object Model. It introduces the Client Object Model and how it can be used from .NET, Silverlight, and JavaScript applications to access and manipulate SharePoint data without server-side code. It discusses the core ClientContext object and how to load and execute queries. It also includes demos of building applications using each technology - .NET, Silverlight, and JavaScript.

- 6. Accessing Data with Client OM Browser JavaScript Controls Server JavaScript OM Object Model Proxy Client Service Proxy Managed OM Content Database Managed Controls Client Server
- 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: ● C:Program FilesCommon FilesMicrosoft SharedWeb Server Extensions 14TEMPLATELAYOUTSClientBin –Microsoft.SharePoint.Client.Silverlight »262KB –Microsoft.SharePoint.Client.Silverlight.R untime »138KB
- 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 builds WSP Module 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()
