Hi Guys,

Thanks for visiting our blog .

In our previous post we were seen how ecma scripts works. To Know more ECMA Script Click here.
In our current post we are going to see how we can get the count of list items inside Sharepoint lists. without using visual studio or server object model.

Before client object model introduced . if we want to implement the same concept we  should have to write server side  code  in C# but now we can  get the items count without touching the visual studio.

Now we are going to look at.

1. Creation of Site pages .
2. How to add a content editor web part.
3. How to write Script in Content Editor webpart.

Step :1 Create a site page in  Sharepoint site .



 Note : Now you are done from out of box side created page in site where SharePoint List there.
Step :2  Add content editor webpart into the page by selecting
               
    --> Edit Page

     -->Add web part

    --> webpart gallery

 --> Media and Content (Category)

                                                                                                                                                                     
-->Content editor Web part .


-->Add the Script inside the Html, Source.


-->  You cane See the  Items count  inside the list




Script Description :

<script type="text/javascript">

ExecuteOrDelayUntilScriptLoaded(MainFunction, "sp.js"); 
  
var objContext = null; 
var objWeb = null     
var objList = null;
var objItem = null;

    function MainFunction() {   
        objContext = new SP.ClientContext.get_current();
        objWeb = objContext.get_web();   
        objList = objWeb.get_lists().getByTitle("Product"); //  Here we are passing the list name
  
        objContext.load(objList);

        objContext.executeQueryAsync(Function.createDelegate(this, this.onSuccess), Function.createDelegate(this, this.onFail));   
    }   

    function onSuccess(sender, args) {
        alert('Item Count: ' + objList.get_itemCount());
    }   

    function onFail(sender, args) {   
        alert('Some error has occured.');   
    }  
 </script>

 ExecuteOrDelayUntilScriptLoaded(MainFunction, "sp.js");


This functions stops loading the script until the page completly gets loaded .


Once the page loaded completly  then it acts as a main function to start the script running.

sp.js

This is the heart file for ecma script . it loads from  layout folder in 14 hive . if it does not loads then we  cant work with ECMA Script .
This  is a sample  of ECMA Script with SharePoint .In our netx post we will see how to work with ECMA Script using Visual Webpart.

Thanks for visiting our blog Hope to see you again for new posts.

Hi Friends,

Thanks for visiting to my blog .

Today am going to explain about ECMAScript Client Object Model (JSOM) in SharePoint 2013,2010

ECMAScript :

ECMAScript is a java script based client side scripting language which is now supported in SharePoint 2010 and can be used to access Client Object Model.

Background

• SharePoint Client Managed Object Model is a SharePoint API that runs on the client side. 
• It converts the API calls made by the application, into XML request and sends it to the SharePoint server. On the server, the XML request is handled by a service called Client.svc where it translates the XML request in to appropriate Object Model calls (SharePoint Server Object Model) and gets the results. 
• After getting the results, Client.svc translates them into JavaScript Object Notation (JSON) and sends back to the Client Managed Object Model. On the client side the JSON response is translated into ECMAScript objects for ECMAScript.

This is just a breif description of our ECMA Script . In  our next articles we will see the examples of ECMAScript.

If you are building a custom master page, and you happen to include a line that looks like this:

In this Post I will let  you know creation of Site Collection .
SharePoint 2013,2010, we can create multiple site collections to a web application .

Site Collection : 
A site collection is a group of Web sites that have the same owner and share administration settings, for example, permissions. When you create a site collection, a top-level site is automatically created in the site collection. You can then create one or more sub sites below the top-level site. 

In SharePoint we can create a site collection in many ways 
1. Out of Box 
2. Programmatically (SOM ).
3. Power Shell.
4. Client Object Model (CSOM).

In this Post i will show you , how to create a site  collection through out of Box feature.

Note : Whenever we create any new web application via out of box we definitely create a site collection as Top- Level Site .  

In Case if you need to create a new site collection for your web application .

 Please  follow  the below step by step procedure for creating SharePoint Collection .

 Open Central Administration  :
In Central Administration page . we can create Site Collection in two ways .
 1. Direct link available under manage web applications.
 2. Click on Application Management link  available at left side of page.

Click on Create Site Collection --> Select the web application URL ( Site Collection target ).


        Here we need to select the web application in which we are targeting our site collection.
 


Template Selection :
We can select one of the available templates provided by the SharePoint . We can also create our own templates.

Site Collection Administrators :
We  can provide  max two site collection administrators.


 After selecting the site collection administrators. please select OK button.


Within few seconds we can able to see our newly created site Collection as below. 




Experience Version : 

At the time of creating the site Collection if we select Experience version to 2010 . 
Then the created site collection looks  as below screen.







 This is one of the ways of creating the site collection in SharePoint 2013.

Hi Friends,


I will show you how to create  a new sub site in SharePoint 2013.

Unlike SharePoint 2010 , we dont have option to create  new Site under (Settings icon ) in SharePoint 2013.

In SharePoint 2013 ,only one extra Click we need to have for creating SharePoint Site .

Settings Icon -->Site Contents---> new Subsite

Hi Friends,

Today i will describe  you about the site columns in SharePoint 2010,2013.


  Site Column :
  A Column which can  be created at root site level and can be accessible inside all the available child sites or Sub Site 's Lists or Document Libraries  under the root site .

Purpose :
   Some  times we get a situation where some columns inside lists or doc libraries needs to be created multiple times and  use them. So at that time  instead of creating a column inside of each and every list simply we can create a site Column at root site level .
Then we can use the site column just by adding to list .


Please find the below steps for creating Site Column using Out of feature .

select settings Icon --->Site Settings

Under Designer Galleries  --Click on Site Column


By Default we can see all the list of Site Columns provided by SharePoint . 
To Create a new site column . Click on Create


 Give Column Name and select  Data Type for the column



Here , If we want to create a new group we can also create new group or we can use existing group but for our understanding i have created a new gropName "NewSiteColumn"



Now you can see , newly created group (newSiteColumnGroup) along with Site Column.



Now we add the Site Column to  your list say (Student List created already ).

Select list -->Click on List Settings





Click on Add From exsiting  site columns  and click on OK

 
 Now go the  List and click on add new item .

You will  be seen the Site Column.as below .


This is how we create new  Site Columns in SharePoint 2010, 2013 .

Hi Guys ,

Some times we come across a situation where we need to know the latest list item version .

Please find the method to get the latest list item version using Server object model.


 Public SPListItem TopListItemVersion(SPListItem item) 
            {      
                if ((item.Versions != null) && (item.Versions.Count > 0)) 
                { 
                    SPListItemVersionCollection versions = item.Versions; 
                    SPListItem latestItemversion; 
                    if (item.Versions.Count > 1) 
                        latestItemversion= item.Versions[item.Versions.Count - 1].ListItem; 
                    else 
                        latestItemversion= item.Versions[0].ListItem; 
     
                    return latestItemversion; 
                } 
                else 
                 
                    return item;            
             }
