What is Web part life Cycle in SharePoint 2013 and SharePoint 2010

Posted by Santhosh, on 11:55 PM

Hi Friends,

 Thanks for visiting my blog .

 In this post , i would  like  to describe the web part life cycle events in SharePoint 2013.
Like Asp.Net life cycle there is also Web Part life cycle. So it is better to understand the web part life cycle.

OnInit:
This method handles initialization of the control.

OnLoad:
This event handles the Load event. This is also used for initialize the control but is not intended for loading data or other processing functionality.

CreateChildControls:
This is the most popular event in web part life cycle. This creates any child controls. So if you are adding any control to display then you have to write in this method.

EnsureChildControls:
This method ensures that CreateChildControls has executed. EnsureChildControls method must be called to prevent null reference exceptions.

SaveViewState:
View state of the web part saved.

OnPreRender:
This method handles or initiates tasks such as data loading that must complete before the control can render. 

Page.PreRenderComplete:
The page fires the PreRenderComplete event after all controls have completed their OnPreRender methods.

Render:
This method is used to render everything.

RenderContents:
Renders the contents of the control only, inside of the outer tags and style properties.

OnUnload:
Performs the final cleanup.
 
Hope this post will help   you......

How to Hide Controls in SharePoint New Form Based on User using ECMA Script.

Posted by Santhosh, on 2:13 AM

Hi Guys,

Thanks  for visiting our blog.

In Share Point we have If condition "If this user is member of this share point group" We can use this condition to check any user belongs to particular group or not.


Scenario:
Check user belongs to a SharePoint Group and Hide some controls in New/Edit Forms on SharePoint Custom List.

                        

Solution:
The following Script which will help you in checking if the current logged in SharePoint user belongs to a SharePoint user group and based on it hide some controls in New/Edit  forms on Custom List.

Step 1: Navigate to your SharePoint 2013 site.

Step 2: From this page select Site Actions | Edit Page:

Edit the page, go to the "Insert" tab in the Ribbon and click the "Web Part" option. In the "Web Parts" picker area, go to the "Media and Content" category, select the "Script Editor" Web Part and press the "Add button".

Step 3: Once the Web Part is inserted into the page, you will see an "EDIT SNIPPET" link; click it. You can insert the HTML and/or JavaScript as in the following:

Script

<script src="/sites/JohnHancock/JS/jquery-1.4.2.min.js"></script><script type="text/javascript">

ExecuteOrDelayUntilScriptLoaded(disableControls, "sp.js");

var clientContext = null;
        var web = null;
        var users ;
        var oList;
        var oListNew;

function disableControls()
{
 clientContext = new SP.ClientContext();
var groupCollection = clientContext.get_web().get_siteGroups();
var group = groupCollection.getById(4);//the SharePoint usergroup
users = group.get_users();
clientContext.load(group);
clientContext.load(users);
currentUser = clientContext.get_web().get_currentUser();
clientContext.load(currentUser);
clientContext.executeQueryAsync(Function.createDelegate(this,
this.onQuerySucceeded), Function.createDelegate(this,
this.onQueryFailed));
RefreshCommandUI();
}
function onQuerySucceeded()
{
if(this.users.get_count() >0)
{
var UserExistInGroup = false;
for(var i=0; i < users.get_count(); i++)
{
//alert(users.itemAt(i).get_loginName());
//alert(this.currentUser.get_loginName());

if(users.itemAt(i).get_loginName() == this.currentUser.get_loginName())
{
UserExistInGroup = true;
break;
}
}
}
if (UserExistInGroup)
{
$('nobr:contains("Approver")').closest('tr').show();
}
else
{
 $('nobr:contains("Approver")').closest('tr').hide();
}
}
function onQueryFailed(sender, args)
{

}
</script>
 


This is how we use to  hide /unhide the columns  in SharePoint Out of box forms.

Posted by Santhosh, on 12:56 AM
Hi Guys,

Thanks for visiting my blog .

While creating  Columns in Custom List  many of us have seen the Calculated  Column .

I will describe the calculated column for Month and year .

Go to the list settings and then click on Create column to add a new column. Give the column name and chose the column type as calculated column. Then in the formula write like below:
=TEXT([Created],"yyyy")



he above formula will return the formula as a single line text, Now if you want to return as integer then you can write the formula like below:

=YEAR(Created)

Similarly
 if you want to store month then follow the above step and write the formula like below:

=Text(Created, "MMMM") : This will return the full month name
=Text(Created, "MMM") : This will return first 3 letters of the month name
=Text(Created, "MM") : This will return integer month

If you want to return the value as an integer then you can write the formula like below:
=MONTH(Created)


Now if you will check the output will come like above :

Difference between SharePoint 2010 List and Document Library

Posted by Santhosh, on 5:34 AM


Hi Guys,


Here we have some  difference between Lists and Libraries in SharePoint



Lists Libraries
SharePoint lists are web based editable tables.It gives us the ability to work with structured data. SharePoint libraries are a list of files.
List is going to store the same sorts of data that you would normally place into a spreadsheet. Library is used to store documents.
 A list contains items that are collections of fields/properties/columns.optionally can have one or more attachment. A library is a list ,but have one and exactly one file associated with each item .A library item also has fields/properties/columns.
 SharePoint list doesnot support check in and check out options.  SharePoint Library supports check in and check out options.
When the user searches for a keyword in a document , if the document is in a list then search returns the list item as the result.  When the user searches for a keyword in a document , if the document is in a library then they find the document listed in the search results.
Example of SharePoint lists are Contact lists,Task lists etc. Examples of DocumentLibraries are PictureLibrary,FormLibrary etc.



What is Look up Column and how to use in SharePoint 2010,2013

Posted by Santhosh, on 4:26 AM

Hi Guys,

Thanks for visiting my blog .

Look up Columnin SharePoint 2010 and 2013

When you create a column, you can specify that the column must contain unique values. This means that the list cannot have any duplicate values in that column. You cannot add a list item that contains a duplicate value, modify an existing list item that would result in creating a duplicate value, or restore an item from the Recycle Bin if it would result in a duplicate value. Furthermore, if you create a lookup column in a source list, and you define that column to be unique, the column in the target list must not contain duplicate values.

Note    Uniqueness is not case-sensitive, so for example, ORD-231 and ord-231 are considered duplicate values.

A unique column must also have an index. When you create a unique column, you may be prompted to create the index and it is automatically created when you click OK. Once a unique column has an index, you cannot remove the index from that column, unless you first redefine the column to allow duplicate values.
