Two ways of Changing an Asynchronous Eventhandler to Synchronous Eventhandler in lists Sharepoint 2010

Leave a comment

Hi we can Change an Asynchronous Eventhandler to Synchronous Eventhandler in lists Sharepoint 2010 in two ways to avoid save conflict error.

First method:

In the elements.xml file just change the name of list and add synchronous tag

<Elements xmlns=”http://schemas.microsoft.com/sharepoint/“>
<Receivers ListUrl=”ListName”>


Second method:

//Create an Empty Eventhandler

 SPEventReceiverDefinition itemAddedEventRec = lstname.EventReceivers.Add();

itemAddedEventRec.Name = “AddItem”;

//Change to Synchronous

itemAddedEventRec.Synchronization = SPEventReceiverSynchronization.Synchronous;

itemAddedEventRec.Type = SPEventReceiverType.ItemAdded;

itemAddedEventRec.Assembly = “Assembly Name”;

itemAddedEventRec.Class = “ClassName”;



“Sign in as different user” option in SharePoint 2013

Leave a comment

We can do it in two ways.

First way:

Just type the url : http://siteurl/_layouts/closeConnection.aspx?loginasanotheruser=true

Second way:

In your sharepoint server installed Server:

  1. Go to path: C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\TEMPLATE\CONTROLTEMPLATES
  2. In that file you will find Welcome.ascx file.
  3. Open the file with Notepad and add the below code exactly before the tag.ID_RequestAcess
  4. signindifferentuser
  5. Just Refresh after the change is done.

The backup file should be restored to a server with version ‘’ or later.

Go to Central Administration –> Application Management –> Manage content databases —> see the name of database.
Now go to Powershell and type this command
Upgrade-SPContentDatabase WSS_Content

In the place of WSS_Content write your content db name.Once its executes.You can restore backup

Using list service to display data in sharepoint site page

Leave a comment

Situation: Need to display a set of data in sharepoint list based on a dropdown in the page. For that if we plan to write a visualwebpart. But while changing the values in the dropdown Postbacks will occur which will be not smooth.

To handle this is in a simple way we can use 1) Ajax 2) List service.

Here I will explain with List service.

1) Create a Sharepoint list “EmployeeList”

2) The list service will be accessed as: http://abc:123/_vti_bin/ListData.svc/EmployeeList (This is an example)

3)Now we need to create a new page in Sitepages.

4) In that new page insert a Content Editor  Web Part (CEWP)

5) Now Open a Notepad and write your Jquery code and save it as Employee.JS and give a reference in the new page created.

Point to remember: You must place the js reference link only in between the PlaceHolderAdditionalPageHead. nOT ONLY .JS  we can refer .css files also in PlaceHolderAdditionalPageHead.

<asp:Content ContentPlaceHolderId=”PlaceHolderAdditionalPageHead” runat=”server”>

<script type=”text/javascript” src=”/SitePages/employee.js”></script>


6) After referencing write a code in employee.js to retrieve all the list data and show them or render it in a tabular form

7) employee.js

$(document).ready(function() {

var url=” http://abc:123/_vti_bin/ListData.svc/EmployeeList ” ;

$.getJSON(url,function(data) {
var count = 0;
html= “<table>”;
$.each(data.d.results, function(i,result) {
var title = result.Title;
var emp=result.Employee;
var empid=result.EMPID;




//dont need headers again here



count = count +1;




8) now we need a content editor webpart to render our html output. here we given according to jquery with a div

<div id=”Result” style=”font-size: 10px; color: blue”></div>

9)take a text file and copy above html code and link that with content editor webpart

10) Then in browser it will render all table data

Suppose if you want filter data with some specific value you must give list service url as like this:

http://abc:123/_vti_bin/ListData.svc/EmployeeList?$filter=EMPID eq ‘1234’ ”



The type or namespace name ‘DataContract’ could not be found (are you missing a using directive or an assembly reference?
