Hide Number of Responses in a Survey

When we create a survey in SharePoint, an overview will be created with several information.

Under some circumstances it might be necessary, to hide the line with the Number of Responses. Because this is a simple html-table that shows the information, a Script Editor webpart and some jQuery could be used to solve this problem.

First, we need jQuery in our site. To make jQuery available, we can use PowerShell PnP, connect to our site and execute the following cmdlet:

Next, we open the overview page of the survey and switch into edit mode for the page (click the gear icon top right and select Edit Page). When in edit mode, insert a Script Editor webpart on the page (we find it in the category Media and Content). When the webpart is added, click Edit Snippet in the webpart and enter the following snippet:

Click Insert and stop editing on the page.

That’s all, the line with the Number of Responses has gone.



Flow to send email for documents that need revision

For a document library in SharePoint Online, I want to send notification mails for documents, where the “NextRevision” date is 30 days in the past or older. The Flow should run once a day.

This sample would send the mails each day, when a document was not modified. To avoid this behavior, add a field to the library, to mark that a notification was sent.

Hide Column in SharePoint EditForm

In some cases, it could be necessary to hide a field in the editform in SharePoint. This could easily be done with the SetShowInEditForm() method from the Client-side Object Model of SharePoint.

In this short demo, I have prepared a demo list with the fields “Target Date” and “Planned Date”. When a new item is created by a user, both fields could be edited. But, when the item was saved, we do not want to be able to modify the value in the “Target Date”.

In the web interface in SharePoint, we do not have any option to change the necessary property of the field. But with PowerShell, this problem could easily be solved. After we have established a connection to our SharePoint site, we can use these four lines of script to do the modification:

When we are using a SharePoint site with modern UI, the field will always be removed, except when we add a new item, because the information pane is always opened in edit mode (in modern UI we do not have a separate view mode).

But when we switch back to the classic UI, we can see a difference.

Display form:

Edit form:

Just done, with a few lines in PowerShell.

Just, to have it complete: the Client-side Object Model has two other methods in the Field-class, SetShowInNewForm() and SetShowInDisplayForm(), to make a similar functionality available in the other forms for the list.

Yes, it is also possible to archive the same goal by modifying the edit form with PowerApps, when we use the modern UI. But this only works with the modern UI and there is still a need for using the classic UI, because we have other options in the classic interface actually not available in the modern UI.


Indexing scanned content in SharePoint Online

The last days I was asked, how to handle indexing of pdf-files that contain scanned content. In these files the content often are just images and an OCR approach is needed to make the content readable and accessible for the crawler.

From my point of view, we have two options to answer the question. The first is a Flow, where we can use the ElasticOCR connector. Actually, the connector is in preview, but it can already get a trial license for your tests. The way of working of the connector creates a new version of the document with readable content for the crawler. Good approach and it does what I expected.

But there should already be another approach to answer the question. For environments that run on-premises, we are not able to use Microsoft Flow, and on the other hand, using this Flow connector will first copy the file and the content to another location, do the processing and then move the results back to our SharePoint or OneDrive library.

There are some development packages for OCR available, I tested with IronOcr. My approach is very simple: in the library, where the document is stored, I create a hidden text field, where I store the text content of the file after the OCR process is done. The SharePoint crawler will pick-up the content of the field and store all necessary information in the index for the search. Searching for any information from the document will show the document in the search results.

The following code is just the result of this proof-of-concept, nothing more. The first part is just the field definition, where the text content will be stored after ORC.

The second part is a very, very simple command line program that takes the item id of a document as the parameter, does the OCR for the document and stores the readable text in the text field of the file item.

So, for handling these documents in the real world, we can use a remote event receiver for SharePoint (Online) or just a simple remote timer job. As always it depends on the environment, where we are working in.

FAQ List with nice User Interface in SharePoint Online

I got the request to create a nice FAQ in SharePoint Online. The user interface should not be a simple list but should be fancy or modern. Additionally, the content should be in two languages, English and German.

So, what would be a simple approach for the solution? The content itself would be a custom list in SharePoint Online, where we have a choice field for the languages. For the answers we use a Note field with FullHtml style.

To display the contents of the list, we use some html, CSS and JavaScript in a Content Editor Webpart. In the JavaScript we query the list by language and build up some html that is added using jQuery. Finally, the added html gets a click function injected to show or hide the answer.

The html and JavaScript will look like this:

To create the structure for our solution, we are using just some PowerShell (with the SharePoint PnP extensions):

The final solution will look like this for the end user:

The complete code for this sample could be found in GitHub:


Prepare Deployment of Azure Web Jobs reloaded

A few years ago, I wrote already an article about creating the zip-file for the Azure Web Job deployment directly in Visual Studio. You can find the article here.

It seems, there is a limit of 50 MB for the zip-file, when you upload the file in the Azure Portal. Now I had the problem for a little more complex timerjob that this file size was exceeded. When we have a look into the bin/release folder, we see some files that are not needed to run the exe-file. So, I made a little modification to the PowerShell script to exclude these files. The new script file looks like this:

Reorder Content Type Fields with PowerShell

When the business is working with a solution, build in SharePoint Online, they often have new requirements. One of these requiremtens most time is, to add new fields to a list or content type. Because we have the SharePoint PnP extensions, the task for adding a new field could easily be solved with the Add-PnPField cmdlet. But…

… often the user wants to have a new field in a special position within the list or content type. This could also be solved using PowerShell, but we need some CSOM code for the solution. The field order is part of the FieldLinks collection of the content type. Most of the time, we have already a field in the content type that could be used as the anchor, after which we want to place the new file. So, first, we need the position of our already existing field (the new field should already be created). We get this information with the following script:

With the position of the anchor field, we can use the following script to move our new field to the desired position in the content type. That could be done with the following script:

When we put this together, we can use the following script to do the move during a provisioning process:

If necessary, and this often makes sense, we can put all these scripts together and use the functions directly in one script.
