SharePoint: Access denied error while calling web service from JavaScript

March 6, 2017 2 comments

Hi Friends,

I would like to share one very specific while calling web service from JavaScript, we were getting exception. Important point to note here is the code is working very fine if we access the page on server. But we are getting JavaScript ‘Error: Access is denied.’ Error while accessing the web page from client machine through browser.


We are getting exception where we are calling the web service.

After some analysis the error came out as HTTP and HTTPS mixed content issue.

In our case HTTPS is configured on load balancer level and on ISS 7 level we have HTTP only hence web service call is working fine.

While accessing from outside URL is getting accessed only with HTTPS and non-secured request is also redirected with secured.

Problem fund that we have used ‘_spPageContextInfo.webAbsoluteUrl’ variable which is providing the HTTP path as SharePoint is unaware with existence of HTTPS as it is configured on load balancer level.

‘_spPageContextInfo.webAbsoluteUrl’ is supposed to give HTTPS path if HTTPS configured on ISS 7 level but as in our case SSL is configured on load balancer hence SharePoint is unaware about SSL.


We have checked the protocol of the browser request using ‘document.location.protocol’ and if it is HTTPS then we replaced HTTP with HTTPS from the output of ‘_spPageContextInfo.webAbsoluteUrl’


This solution is working fine both in the case of HTTPS and HTTP.

Though this scenario is very specific but still this may help someone to understand the issue better.

SharePoint 2013: Modal Dialog position and scrolling issue with lengthy page

We have come across an issue with SharePoint modal dialog, while working with a lengthy page where due to some lengthy content vertical scroll bar were coming. We developed one web part form, which we have added at the center of the vertical screen. From that web part we can open a SharePoint Asset picker to select the image which opens a model dialog. The functionality was working as expected but we found an UI level issues.

Problem: When we try to launch SharePoint ‘Modal Dialog’ from the bottom of the huge scrolled page, we are not able to see the dialog and only see the bluer screen (overlay). The actual model dialog is getting opened at the top of the page and because of the current scroll position which is somewhere in between the screen or at the bottom, we are not able to see the popup.

Solution: The model dialog location is set by CSS class on the top of the screen, we need to override the css class to change the property. The name of the class is ms-dlgContent. We can add following css class in either master page or respective CSS.

SharePoint 2013: Exception while creating default associated groups through PowerShell

While new site collection provisioned default security groups been provisioned when we create it from central administration but not when the site collection was created using script. For that we need to call a function ‘CreateDefaultAssociatedGroups’. This method actually created default associated group example member, Owner and Visitor group and add the group owner as the first parameter provided to the method call.

When I tried it some cases it worked and in some cases I was getting error “Exception calling “CreateDefaultAssociatedGroups” with “3” argument(s): “User cannot be found”

While analyzing the issue the issue I found that I am passing only first mandatory parameter as the user logon name of the group owner. Like –


And then I was getting error Exception calling “CreateDefaultAssociatedGroups” with “3” argument(s): “User cannot be found.” And the default groups are not getting added.

Further analysis concluded that the user I was passing as group owner was not getting added and hence the exception is thrown.

We have used EnsureUser before calling CreateDefaultAssociatedGroups function to make sure that before the call user should be available in user information list like –


SharePoint 2013: Getting lookup column values in JSLink

Hi Friends,

While working on of the development requirement related to JSLink I came across a scenario where a lookup value needed to be shown in a list view web part.

I wanted to demonstrate with following code how we can achieve to show the lookup values form single valued or multi valued lookup.

Before that I would like to show the relationship between the lists I used to show the demonstration.

I have created following two custom lists for demonstration.

First list with following column –



The content in First list will like something –


Second list having lookup column from first list –



The content in second list like following –


Following code will show how to get the single or multi valued lookup values and show.

(function () {

var overrideCtx = {};
overrideCtx.Templates = {};
overrideCtx.Templates.Item = CustomPortalPageItem;
function CustomPortalPageItem(ctx) {
var html = "";
html += '<div title="' + ctx.CurrentItem.Title + '"></div><div>'+GetLookupValues(ctx.CurrentItem.Test11,"lookupValue")+'</div>';
return html;

function GetLookupValues(inputArry,originalColumnName)
var retHtml="";
for(var loopcnt=0;loopcnt<inputArry.length;loopcnt++)
if (typeof(inputArry[loopcnt][originalColumnName]) != 'undefined' && inputArry[loopcnt][originalColumnName] != null)
return retHtml;

After this it will look like following,you can then apply beautiful HTML to it.

SharePoint 2013: Designer workflow error with ‘Call HTTP web service’ action

February 17, 2015 4 comments

While working on one of the workflow development task, it was required to have a web service call to fetch data from SharePoint. To achieve that I used ‘Call HTTP web service’ action but with that I was getting following exception “Unable to deserialize HTTP response content. Expected Content Type: ‘application/json’, ‘text/plain’ or ‘text/html’”.


After struggling with this issue, the solution I used thought to share the solution with developer community.

Solution: The reason for the issue is, by default response from SharePoint REST is in XML and SharePoint designer workflow not able to parse the xml and needs JSON response. To resolve this issue we need to pass Accept and Content-Type as application/json;odata=verbose to request headers. This way we will get JSON response. To resolve this follow bellow steps.

  1. Go to SharePoint 2013 designer.
  2. Build a Dictionary variable named ‘WSHearder’WF1
  3. Add two values in newly created dictionary
Accept = application/json;odata=verbose
Content-Type = application/json;odata=verbose
  1. Now select ‘Call HTTP web service’ action and select Properties.              WF3
  2. Select newly created dictionary variable as value for ‘RequestHeaders’.WF4
  3. Press OK and publish the workflow.

SharePoint: Using Papercut for testing the email functionality in SharePoint.

October 31, 2014 Leave a comment

In many scenarios while working with SharePoint we may come across requirement to test emails. Like email alerts, emails from workflow, timer jobs or event receivers etc. In my case I need to test emails from Timer job.
While development phase it is not always possible to have a SMTP sever available to test those kind of functionality and in those scenarios Papercut is best utility available for our help. Papercut is a simplified SMTP server designed to only receive messages and serve the purpose of light weight SMTP.
You can use Papercut in .Net development or SharePoint development. You just need to download and install the Papercut on your SharePoint server.

Some points to consider while using Papercut with SharePoint-
1. Papercut is only to receive emails.
2. In case of ASP.Net application provide host=”″ port=”25″ in web.config file under mailsettings section.
3. For SharePoint, If you have single server farm then you don’t need to worry just install Papercut and set the ‘Outbound SMTP Server’ to localhost or in ‘Configure outgoing e-mail settings’ under central admin, System settings.
4. You can now test by creating simple alert on any list.
5. If you have muti-server farm and testing email from timer job then need to find on which server timer service is running and on that sever you need to install Papercut also give this server IP in ‘Outbound SMTP Server’ in ‘Configure outgoing e-mail settings’ under central admin, System settings.
6. If timer service running on more than one server then make sure port 25 open between those servers to get emails from timer job.
Hope this will help.

SharePoint 2013: Item template not called in JSLink with group rendering

July 10, 2014 3 comments

Hi Friends,

I have explained the Group rendering with JSLink in one my previous blog. I will explain a common problem and a solution for that while group rendering with JSLink.


While rendering grouping in view with JSLink, We normally face an issue that item rendering handler ‘overrideCtx.Templates.Item’ is not getting called. Group rendering was working fine in my case but not item level rendering.


Initially I thought something wrong with JSLink file but after analysing and debugging I found the problem is with the grouping configured in data view.

To fix this issue edit your data view and go to grouping section of the view. Change ‘By default, show groupings’ setting to ‘Expanded’ and save the view and bingo it will start working.

Following image shows the setting in data view –

JSLink Group

JSLink Group

If you are provisioning data view declaratively then you need to add Collapse=”FALSE” to your <GroupBy node.


Possible reason for this problem is, while the groups shown in collapsed state item in that group are not loaded initially and once you click to expand the group it will be loaded on demand hence item template not gets called initially as items not loaded.

Hope this will help some of the developer looking for same kind of answer.

Happy coding!!!
