Performance issue during SharePoint list data bind to html table using Ajax call(Rest API)

Hello,
I am having multiple lists in my SharePoint Site. I am using SharePoint REST APIs to get data from these lists and bind a HTML Table. Suppose, I have 5 lists with 1000 records each, I am looping 5000 times to bind each row(record) to this html table. This
is causing performance issue which is taking a very long time to bind.
Is there any way So that I can reduce this looping OR is there any better approach to improve the performance. Please kindly Suggest. Thank you for your help :)
Warm Regards,
Ratan Kumar Racha

Hi Racha,
For handling large data binding in a page,
AngularJS would be a great option if you might would worry about the performance.
You can get more information about using AngularJS from the two links below:

How to read data from SharePoint list and append to html table?

Hi All,
I would like to create custom view of SharePoint list, so want to append those sharepoint list items in a custom html table design using content editor webpart.
How to achieve this? thanks in advance!

Content edit web part is not the right control. You can either Content Query Web Part
or Data view web part, where you need to modify xslt template using
SharePoint Designer and can render list data as per choice.

Perfomance issue with SharePoint List.

Current System:
Our application (for submitting and publishing articles) is using WSS 3.0
to store content and host workflows.
Article content like PDFs, Images & Videos are stored in a SharePoint document library.
There is also a list in which we have configured a custom state machine workflow. While creating an list SP item from the UI, instance of the configured workflow instance will be triggered and start monitoring.
Each article belongs to a Journal. We have TBs of data stored in content databases. Initially there was only one site collection (“http://<myweb:8080>/ArtcleLibrary”) and entire article data was storing it the same document library.
Later we decided to split the document library based on journal.
To achieve better scalability, we have now changed the application architecture by creating site collection for each journal and keep article content (there are many articles in a journal) in corresponding site collections. We have added more content databases
and sites collections are equally distributed among these Dbs.
Now it is like (“http://<myweb:8080>/<journalID>/ ArtcleLibrary”)
Actual Problem:
We have achieved scalability in the case of content management by splitting document libraries among different site collections and content databases.
But still the SP list for managing workflow is in the initial site collection (“http://<myweb>:8080/WorkflowTasks”). This single list contains now 60,000 items (=60,000 workflow instances) even if we deleted completed list items older than 3 months.
We have performance issues with the current workflow list. It is taking time (avg 20s) to create/read list item from the SP List. Sometimes items are not getting created in the list item.
From MSDN I came to know than there are recommended count for items in SPList (2000
or 5000 items).
What is the best solution to solve the above performance issue with SharePoint list?
Whether the above mentioned our approach to document library will work for SP list also (means split current SP List and keep in each Journal site collection)?
Please advise.

Hi Andrew,
Thanks for your post.
I still have some doubts.
If we go like this, will OWSTIMER be able to handle workflows (custom workflow is attached to SP List) of these many site collections. We have now more than 600 site collections.

i just follwed above link it work perferfectly fine for building tree view but i don't want server control.

My ultimate goal is to generate xml string like above format without building tree view.
I want to generate xml using web service and using xml i could convert into nested Tree View Accordian in html.
I developed some code but its not working to generate xml /string.

Hi,
According to your post, my understanding is that you want to custom action for context menu in "Site Content and Structure" in SharePoint 2010.
In "SiteManager.aspx", SharePoint use MenuItemTemplate class which represent a control that creates an item in a drop-down menu.
For example, to create or delete the ECB menu for a list item in
"Site Content and Structure", we can follow the steps below:
To add the “My Like” menu, we can add the code below:
<SharePoint:MenuItemTemplate
UseShortId=false
id="OLListItemLike"
runat="server"
Text="My Like"
ImageUrl="/_layouts/images/DelItem.gif"
ClientOnClickNavigateUrl="https://www.google.com.hk/"
/>
To remove the “Delete” menu, we can comment the code below:
<SharePoint:MenuItemTemplate
UseShortId=false
id="OLListItemDelete"
runat="server"
Text="<%$Resources:cms,SmtDelete%>"
ImageUrl="/_layouts/images/DelItem.gif"
ClientOnClickScript="%SmtObjectDeleteScript%"
/>
The result is as below:

MenuItemTemplate.ClientOnClickScript property (Microsoft.SharePoint.WebControls)

PowerPivot report data refresh error Data source as SharePoint list Data Feed

Hi All,
I am facing a problem on auto refresh, the report data source is SharePoint list Data Feed, I saved it my PC desktop when I set up auto fresh it fails then I moved the SharePoint list data feed "atomsvc" file to A SharePoint Data feed library then connected
to report started a manual refresh it was success, after next schedules it failed.
Error massage:
Errors in the high-level relational engine. The following exception occurred while the managed IDbConnection interface was being used:
The network path was not found. ;The network path was not found. The network path was not found. .
A connection could not be made to the data source with the DataSourceID of '82f49f39-45aa-4d61-a15c-90ebbc5656d',
Name of 'DataFeed testingreport'. An error occurred while processing the 'Testing Report' table. The operation has been cancelled.
Thank you very much !

If you are using Claims Auth then this is a known limitation. Auto refresh only works under Classic Auth.
I trust that answers your question...

SSDT - Using a SharePoint list data feed as source - "column does not exist in the rowset" error

Hey guys!
So, I want to use a SharePoint list data to create a cube/tabular model, in order to make a complex analysis in PPS using MDX.
To create the tabular model, I'm using the SS Data Tools, and importing a feed from the respective SharePoint list (using the _vti_bin/listdata.svcextension and then selecting the list(s) I wanna to import).
Everything looks fine and smooth, I can select and preview the data in the table import wizard, but in the end, when importing, I always get this error IF the table has one or more row of data (if the table is empty, it's ok...) - the <...>
column doesn't exist in the rowset.
(Curiously, when I have the same procedure in PowerPivot for Excel, I have no problems, everything works fine. The problem is that then I get again errors if I try to create a tabular model on SSDT importing a PowerPivot file).
Here's the error:
Had you already tried this in SSDT? Are you experiencing the same trouble?
Best regards, and thanks in advance!

I noticed something else too.
I can't process Tabular Models on both SSDT and SSMS (2012), but I can process Tabular Models created on PowerPivot.
I tried to create a Data Feed connection on PowerPivot, and it was successfully created. However, if restoring the PowerPivot Tabular DB on my SSAS Tabular instance and processing (full) the model through SSMS, it won't work.
Is there anything different on PowerPivot and SSDT related with Partitioning or connections to the data sources?
Regards,
Jorge
Jorge Mateus
Update:
When trying to Restore a PowerPivot file on my SSAS Tabular Server and full process the model:
The operation failed because the source does not contain the requested column. You can fix this problem by updating the column mappings.
More Details:
The 'X' column does not exist in the rowset.
An error occurred while processing the partition 'X_81dabac5-c250-4a8c-8832-ad7fcedd35cb' in table 'X_81dabac5-c250-4a8c-8832-ad7fcedd35cb'.
The current operation was cancelled because another operation in the transaction failed.
X is the first column of the source table, no matter if I chose others on the PowerPivot table.
When trying to import data from a data feed using SSDT:
The 'X' column does not exist in the rowset.
An error occurred while processing the partition 'X_ee6be81f-2235-4113-b404-cfcb20647a38' in table 'X_ee6be81f-2235-4113-b404-cfcb20647a38'.
The current operation was cancelled because another operation in the transaction failed.
X is the first chosen column to import.

Hi Vision2040,
Based on my research, it’s not supported that making Unpivot data from a sharepoint list currently.In general, we can use PIVOT and UNPIVOT relational operators to change a table-valued expression into another table.

Extracting Raw Data Using Excel Services REST API

I am trying to create a home page in SharePoint 2013 that shows quick stats based on an Excel workbook stored in a document library. Through my research I found that I could leverage the Excel Services REST API to pull the information I need from the workbook
via URIs and display it on a SharePoint page in a seamless manner.
The problem I am having is pulling the data I need as raw text.
For example, I can create a page in HTML that says "Our sales for the month grew by [X%]" and use an img src tag that points to
http://sample.com/_vti_bin/ExcelRest.aspx/Documents/workbook.xlsx/Model/Ranges('Sheet1!A1')?$format=image to show a picture of cell A1 which contains the data I want to show inline on my page.
I want a way to pull the data in cell A1 as raw text so that I can format it as part of the HTML page. I tried using
$format=html, but that just takes me to a separate page where the cell is formatted exactly as it is in the workbook.
Is there a way to do what I am trying to do? The more detailed your response can be, the better as I am fairly new to these features. And also, is there a way to perform calculations of cells in HTML? Thanks in advance.

Hi,
According to your description, you might want to extract text value from a specific cell in an Excel file using Excel Services REST API.
As there is no such predefined format can be used to return text value only, I would suggest you return the value as json format, then parse it and set to your HTML
tag using jQuery.
Here is a <p> tag with a script which can set the value of the <p> tag with the value gets from cell “A1”:
<p id="cell1">test</p>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script type="text/javascript">
//replace the strings below with yours
var libName = "Shared Documents";
var fileName = "Book1.xlsx";
var rangeName = "A1";
$(function(){
var s = getCellValue(libName, fileName, rangeName);
$("#cell1").html(s);
function getCellValue (libName, fileName, rangeName)
var cell = "";
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_vti_bin/ExcelRest.aspx/"+libName+"/"+fileName+"/model/Ranges('"+rangeName+"')?$format=json",
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
dataType: "json",
async: false,
success: function (data) {
console.log(data.rows[0][0].v);
cell = data.rows[0][0].v;
error: function (data) {
console.log(data);
return cell;
</script>
You can add it into your page via a Content Editor Web Part, it will take effect after the page loaded.
Here are two links about how to add code into page via Content Editor Web Part:

Error while retrieving data from PL/SQL Table using SELECT st. (Urgent!!!)

Hi Friends,
I am using Oracle 8.1.6 Server, & facing problems while retrieving data from a PL/SQL Table:
CREATE or REPLACE PROCEDURE test_proc IS
TYPE tP2 is TABLE of varchar2(10); --declared a collection
dt2 tP2 := tP2('a','b','c');
i NUMBER(8);
begin
SELECT COUNT(*) INTO i FROM TABLE(CAST(dt2 as tP2));
DBMS_OUTPUT.PUT_LINE('**'||i);
end;
While executing the above procedure, I encountered foll. error:
ERROR at line 1:
ORA-00600: internal error code, arguments: [15419], [severe error during PL/SQL execution], [], [],
ORA-06544: PL/SQL: internal error, arguments: [pfrrun.c:pfrbnd1()], [], [], [], [], [], [], []
ORA-06553: PLS-801: internal error [0]
Can anyone please help me, where the problem is??
Is it Possible to retrieve data from PL/SQL TABLE using SELECT statement? & How ?
Thanks in advance.
Best Regards,
Jay Raval.

Thanks Roger for the Update.
It means that have to first CREATE TYPE .. TABLE in database then only I can fire a Select statement on that TYPE.
Actually I wanted to fire a Select statement on the TABLE TYPE, defined & declared in PLSQL stored procedure using DECLARE TYPE .. TABLE & not using CREATE TYPE .. TABLE.
I was eager to know this, because my organization is reluctant in using CREATE TYPE .. TABLE defined in the database, so I was looking out for another alternative to access PL/SQL TABLE using Select statement without defining it database. It would have been good if I could access a PLSQL TABLE using Select statement Declared locally in the stored procedure.
Can I summarize that to access a PL/SQL TABLE using SELECT statement, I have to first CREATE TYPE .. TABLE?
If someone have any other idea on this, please do let me know.
Thanks a lot for all help.
Best Regards,
Jay Raval.
You have to define a database type...
create type tP2 is table of varchar2(10)
CREATE OR REPLACE PROCEDURE TEST_PROC
IS
dt2 tP2 := tP2('a','b','c');
i NUMBER(8);
begin
SELECT COUNT(*) INTO i FROM TABLE(CAST (dt2 AS tP2));
DBMS_OUTPUT.PUT_LINE('**'||i);
end;
This will work.

How do u save datas more than one table using net beans ide using JSF

Hi,

I save / delete / update / New master table using POJO (Plain Old Java Objects), database - oracle and Toplink Persistence Unit.
How do u save data more than one table using net beans ide using JSF (I am using POJO) ?

So, please guide me the reference books, articles. I need the basic understanding of JSF, net beans IDE.[JSF: The Complete Reference|http://www.amazon.com/JavaServer-Faces-Complete-Reference/dp/0072262400] is a good book. The [JSF specification document|http://jcp.org/aboutJava/communityprocess/final/jsr252/index.html] is also a good reading to understand what JSF is and how it works. There are also javadocs and tlddocs of Sun JSF Mojarra.

How to retrieve sharepoint list data and show it on excel-addin using C#

Hi,
we have a sharepoint list where all students are present. we wanted to get the data from the list and show it via excel addin (VSTO) (something like save,retrieve buutons) . we have some more business logic which need to be performed before the data is retrieved
. once data is shown on excel , user modifies it and update/save the record back to sharepoint.
can you please give some samples and suggest any links to start with development.
Thanks
chaitu

Hi chaituatp,
For this requirement, I would suggest you to get familiar with how to create VSTO applications, and how SharePoint object model works. Here are some sample code about this:

SSRS and data from SharePoint lists - special characters in HTML

Hi All,
This may not actually fit into this forum, but here goes anyway...
We're using SSRS to report on data stored in Project Server workspaces (so SharePoint lists). Prior to upgrading to 2013, we could pull this data in and set the "Placeholder properties" of the text box to interpret HTML tags as styles and it would
format everything as it appeared in the SharePoint list. Now that we have upgraded to 2013, this works with a few notable exceptions - some special characters are rendered as their escaped/encoded (whatever the term is) - so a colon which is within the text
field in SharePoint, rather than appearing in the SSRS report as ":" appears as ":".
These are multiline, rich text formatted columns in the SharePoint list. Using =Replace(Fields!Description.Value,":",":") in the report makes the appropriate replacement, but given that this occurs with a handful of other special
characters as well, this solution becomes very unruley very quickly. Has anyone else encountered this, or does anyone have any other suggestions for a work around?
If not now, when?

Facing same issue but having no solution, please suggest..

Excel Services with SharePoint List Data in SharePoint 2013 - Chart is not refreshing automatically

Hi Everyone,
This is My req: I m going to display pie chart and Bar chart in share point 2013.
Steps I have follwed:
1. Export the list to excel.
2.Using the Power Pivot table I have done the chart.
3. Uploaded into document Library.
4. Added into the web part.
Chart are displaying. But When ever user added the data into the list chart is refreshing.
Is there any option to refresh the data in chart? Waiting for valuable replies.
Regards, Manoj Prabakar

SharePoint lists as data sources in Excel Services is not supported.That's the reason refreshing is not working. There are some work around you can use -
Export as Data Feed - Export your SharePoint list as Data Feed , use this data feed to a PowerPivot for Excel workbook and publish this PowerPivot using Excel Services.
User-defined functions - write UDF in C# and extend the Excel Services functionality to work with SharePoint lists.

Web Services API -
The Web Services API can be used to push data from a database and then refresh the data in a SharePoint Server list by using Excel Services.
JavaScript Object Model - The JavaScript Object Model for Excel Services in Microsoft SharePoint Server 2010 provides many solutions for Excel Services.
