Event Receiver in SharePoint 2010

Microsoft Visual Studio 2010 provides a project type that enables you to build event receivers that perform actions before or after selected events on a Microsoft SharePoint 2010 site. We can create Event Receivers (Event Handlers) to take care of things for us when specific things happen. For example, we can subscribe to the "ItemAdded" event for a specific list, and have our custom code execute when the event fires.

The event receiver will change the Title of the item to current year Time once it’s added to the list. We will create and deploy the solution as a farm and will run in debug mode.

·         Open Visual Studio 2010 and create a new Project.

·         In project types select Event Receiver and give it a name.

·         Select .net framework 3.5.

Next in the SharePoint Customization Wizard, choose deploy as a farm solution and specify the site URL where you want the event handler to be deployed as shown in the below figure:

Next, in Event Receiver Settings dialog select the “List Item Events” as a type of event receiver and “Custom List” in the Item source dropdown. Select “An Item was Added” from Handle the following events as shown below:

Next, we will write some code to change the Title of an item to the current year when it is added to a custom list.

using System;

using System.Security.Permissions;

using Microsoft.SharePoint;

using Microsoft.SharePoint.Security;

using Microsoft.SharePoint.Utilities;

using Microsoft.SharePoint.Workflow;

namespace EventHandlinginSP.EventReceiver1

{

    public class EventReceiver1 : SPItemEventReceiver

    {

        public override void ItemAdded(SPItemEventProperties properties)

        {

            base.ItemAdded(properties);

            SPListItem _currentItem = properties.ListItem;

            _currentItem["Title"] = DateTime.Now.Year;

            _currentItem.Update();

        }

    }

}

To build and deploy an application press “F5″.

Once press F5 the solution gets deployed to your site and your Visual studio project goes into a debug mode. Now we will create a new custom List “My List” and add a new item to test our handler.

Create A Custom  List and add new item , will give you the result!

Visual Web Part in sharepoint 2010

 Visual Web Part Project Creation

In this task, you create a Visual Web Part project in Microsoft Visual Studio 2010.

1. Start Visual Studio 2010, click File, point to New, and then click Project.
2. Navigate to the Visual C# node in the Installed Templates section, click SharePoint, and then click 2010.
3. Select the Visual Web Part project template, provide a name, a location for your project, and then click OK.


Figure 1. Select Visual Web Part project type

1. In the What local site do you want to use for debugging dropdown, select the site to use (such as http://localhost/sites/SampleWebSite). Also select the Deploy as a farm solution option and then click  Finish.

After the project is created, Solution Explorer contains the default Visual Web Part named VisualWebPart1 (see Figure 2). Also see in Solution Explorer the presence of the Features and Package nodes. A feature organizes your application in a way that SharePoint Foundation understands. Features can be deployed to SharePoint Foundation at the site or Web level. The package contains features and other assets used when you deploy solutions to SharePoint Foundation.

[note: better remove the default visual webpart and a new visual wbpart with a good name, otherwise all your visual webpart have the same name ,that is VisualWebPart1 ]

Figure 2. The SampleWebPart project in the Solution Explorer 

Add the following code:

Button btn =null;

Label lb=null;

protected override void  CreateChildControls (....)

{

lb=new Label();

 btn=new Button{ text="Hello"};

btnClick+=new EventHandler(btn_Click);

this.controls.add(lb);

this.controls.add(btn);

}

void btn_Click()

{

lb.Text="We are fine";

}

/* usually we get a flow layout , we dont 've any control over the position of controls.for that we use RenderContents method   */

 Protected override  void RenderContents(..)

{

writer .RenderBeginTag(HtmlTextWriterTag.Table);

writer .RenderBeginTag(HtmlTextWriterTag.Tr);

writer .RenderBeginTag(HtmlTextWriterTag.Td);

lb.RenderControl(writer);

writer.RenderEndTag();

writer .RenderBeginTag(HtmlTextWriterTag.Td);

btn.RenderControl(writer);

writer.RenderEndTag();

writer.RenderEndTag();

writer.RenderEndTag();

}

Build and Deploy the Web Part

In this task, you build and deploy the Web Part project.

Build and deploy the project by using one of the following options:

• When debugging the SharePoint solution, use the F5 key to build and deploy your solution. By doing this, the debug experience includes steps such as help for creating a Web Part Page and resetting Internet Information Services (IIS).

• Alternately, you can build and deploy your solution by clicking the Build menu, selecting Build Solution, verifying that the solution builds without any errors, and then selecting Deploy Solution.

Create a Webpart Page

In this task, you create a Web Parts page to contain the Web Part, unless one has already been created for you.

Here is a sample webpart page

1. If you clicked F5 to debug your application, by default, the page where you create a Web part page is displayed. Otherwise, open the SharePoint site, click Site Actions, click View All Site Content, click Create, scroll and select the Web Part Page option.
2. In the Web Part Page screen, provide the information requested about that particular Web Parts page. For example, provide a name (SampleWebPartPage) and layout template for the page.
3. In the Document Library dropdown, select Site Pages, and then click Create. SharePoint creates and displays your Web Parts page.

Add the Web Part to the Web Parts Page

In this task, you add the Web Part to the Web Parts page and test the solution.

On the Web Parts page, click into the Add a Web Part text in the zone where you want the Web Part displayed.

In the Categories list, click Custom. In the Web Parts box, click your visual webpart name.

In the About the Web Part box at the top of the page, click Add. The Web Part is added to the zone that you selected as shown in Figure 4. Note that the lists and SubWebs are displayed in a hierarchical view.

Creating a Basic Web Part in sharepoint 2010

Creating a Basic Web Part

1. Start Microsoft Visual Studio 2010.

2. On the File menu, point to New, and then click Project. 

3. In the New Project dialog box, in the Installed Templates pane, expand the SharePoint node under the programming language that you want to use, and then select 2010.

4. In the Templates pane, select Empty SharePoint Project.

5. Type FirstWebpart as the project name, and then click OK.

6. In the SharePoint Customization Wizard, select Deploy as a sandboxed solution, and then click Finish.

7. In Solution Explorer, click the FirstWebpart  project.

8. On the Project menu, click Add New Item.

9. In the Add New Item dialog box, select the Web Part template, type DisplayMessageWebPart as the Name, and then click Add.

To create the Web Part property

1. In the DisplayMessageWebPart file, copy and paste the following code to create a basic customizable property.

private string customMessage = "Hello, world!";

public string DisplayMessage

{

    get { return customMessage; }

    set { customMessage = value; }

}

2. Add the following tags above the public declaration to allow changes on a per-user basis.

[WebBrowsable(true),

  WebDescription("Displays a custom message"),

  WebDisplayName("Display Message"),

  Personalizable(PersonalizationScope.User)]

Now you have created a personalizable Web Part property.

• The WebBrowsableAttribute attribute ensures that your custom property renders in the editing tool pane in SharePoint Foundation.

• The WebDescriptionAttribute attribute displays a tooltip to help guide users when they are editing your custom property.

• The WebDisplayNameAttribute attribute shows a display name for your custom property.

• The PersonalizableAttribute attribute determines whether changes to your custom property affect all users or only individual users.

Overriding the CreateChildControls Method

By overriding the CreateChildControls method, you can tell the Web Part what operations to perform when the page is visited. In this example, the Web Part renders the user-defined text.

To override the CreateChildControls method

protected override void CreateChildControls()

{

    base.CreateChildControls();

    LiteralControl message = new LiteralControl();

    message.Text = DisplayMessage;

    Controls.Add(message);

}

Deploying and Testing the Web Part

 Press F5 to deploy the Web Part.

1. Click Site Actions, and then click More Options.

2. On the Create page, click Web Part Page, and then click Create.

3. On the New Web Part Page page, for the Name, type DisplayMessageWebPartPage, and then click Create.

4. Click Add a Web Part in the Header zone.

5. On the ribbon, click the Insert tab, and then click Web Part.

6. In the Categories pane, click Custom.

7. In the Web Parts pane, click DisplayMessageWebPart, and then click Add.

8. On the ribbon, click the Page tab, and then click Stop Editing

Client Object Model

Client Object Model is a  feature of SharePoint 2010. It provides programming in a SharePoint site using .Net Managed Code or JavaScript.

The Client Object Model provides almost all the programming features of the Server Object Model plus advantages on deployment. The Client OM (Client Object Model) is being used as the core programming aid for SharePoint 2010 and thus widely used in the market.

Advantages

1. Less Deployment Hassles: Using the Client OM, you do not need to install the components required by Server Object Model. Thus the Client OM provides significant conveniences for the end user.
2. Language Flexibility: We can use the following languages to work with the Client OM:
   
   a. Microsoft .Net
   b. Silverlight
   c. ECMA Script (JavaScript / Jscript)
    
3. Query Speed Optimizations: In the Client OM, reduced network traffic is attained using Query Optimizations. Thus the user will feel reduced round trips and other advantages like paged results etc.
4. everywhere using COM we can access the SharePoint data from the client side browser itself with Silverlight and ECMAScript applications.
5. Web parts with very rich user interface can be developed with the help of Silverlight and jQuery. For example, we can create web parts like video and image galleries with beautiful animations where the videos and the images can be stored in the SharePoint libraries and retrieved using COM.
6. COM along with JavaScript or jQuery can be implemented with just a Content Editor Web part within the browser or from the SharePoint designer without opening the Visual Studio. You can read about it here on how to do that.
7. When we save your site as a template. The application developed with ECMAScript or Silverlight application implemented with Client Object Model would come along with the template which would be very helpful during migrations though we need to take care of any hard coded values.
8. No IISREST is required while deploying a Silverlight or an ECMAScript application implemented with COM.
9. We can have SharePoint accessed from the client desktop using Windows forms or WPF applications implemented with COM. We can develop desktop gadget kind of applications which would be displaying the new announcements added to the “Announcements” list.
10. No SharePoint installation is required in the development machine. Only the dll’s are required if you are going to develop Silverlight applications.

Disadvantages

1.      We cannot elevate the privilege or Impersonate in COM as in Server Object Model. That is, we cannot use the RunWithElevatedPrivilege kind of a delegate. Therefore, the results retrieved using COM will always be security trimmed by default.

2.      The range of classes available to access SharePoint data is very limited in COM. For example, we do not have Classes for accessing User Profiles. We need to go for SharePoint web services.

3.      We cannot access the objects of another site collection in COM while implementing in Silverlight or in ECMAScript. We will get “The security validation for this page is invalid.” if we try to do so. So, we cannot develop applications to read the data from another site collection.

4.      Silverlight web parts fail to load by giving an error message saying “Could not download the Silverlight application or the Silverlight Plugin did not load. To re-configure the Web Part or to provide a different Silverlight application (.xap), open the tool pane and then click Configure.” when it takes more than 5 seconds to load.

5.      We cannot retrieve recurring events from a SharePoint calendar list in Client Object Model.

Client Object Model vs Server Object Model in SharePoint 2010

Client Object Model vs Server Object Model in SharePoint 2010 ?

Server Object Model	Client Object Model
Server Object Model is like a Production Server Environment to access the data where shapoint server installed on the machine .	Client Object Model  can access the data from the system where sharepoint server is not  installed on the machine via Web Services , API , JavaScript etc
Most extensive set of options to customize SharePoint 2010. Any Components consuming server-side object model needs to be deployed on the server	Client OM APIs are wrappers around a custom Web service that calls the server-side object model.
Slower Performance than Client OM and REST API(s)	Better Performance than server-side OM
Synchronous	Asynchronous
Server Object Model  is slower than client object model.  But to access Farm object we can use Server object model only	Client object model gives result in fast manner, but there is a limitation. The limitation is, we can not access Farm Object using Client object model.
