SharePoint WebPart Life Cycle

Javascript SharePoint , list or library
SharePoint WebPart Life Cycle
It's important to know everything about webpart events and the sequence to avoid development mistakes.

Initial Load:

Events fired when a web part is initially loaded.

OnInit 
OnLoad
EnsureChildControls 
CreateChildControls 
EnsureChildControls 
CreateControlCollection 
EnsureChildControls (many) 
OnPreRender 
EnsureChildControls (many) 
SaveViewState 
RenderControl 
Render 
RenderControl 
RenderContents 
RenderChildren 
OnUnload 
Dispose

Post-back:

OnInit 
LoadViewState
EnsureChildControls 
CreateChildControls 
EnsureChildControls 
CreateControlCollection 
EnsureChildControls (many) 
OnLoad
btnUpdate_Click
OnBubbleEvent
EnsureChildControls 
OnPreRender 
EnsureChildControls (many) 
SaveViewState 
RenderControl 
Render 
RenderControl 
RenderContents 
RenderChildren 
OnUnload 
Dispose



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.

Javascript SharePoint , list or library
SharePoint 2013 Search REST API
You can use the Search REST service to submit Keyword Query Language (KQL) or FAST Query Language (FQL) queries in your apps for SharePoint, remote client applications, mobile applications, and other applications.

The Search REST service supports both HTTP POST and HTTP GET requests.

GET requests

Construct the URI for query GET requests to the Search REST service as follows:

/_api/search/query

For GET requests, you specify the query parameters in the URL. You can construct the GET request URL in two ways:
  • http://server/_api/search/query?query_parameter=value&query_parameter=value
  • http://server/_api/search/query(query_parameter=value&query_parameter=)
POST requests

You construct the URI for query POST requests to the Search REST service as follows:

/_api/search/postquery

For POST requests, you pass the query parameters in the request in JavaScript Object Notation (JSON) format.

using (var site = new SPSite("http://sharepoint-portal"))
{
    using (var web = site.OpenWeb())

       using (var fs = new FileInfo(@"C:\Documents\mydoc.docx").OpenRead())
 
       {
        documentBytes = ..... // get the documents bytes
