Get thumbnail URL programmatically in SharePoint

October 4, 2019 / / 0 Comments

SharePoint Picture Libraries offer an out-of-box feature for image compression and optimization, specially when working with thumbnails. After uploading an image to a Picture Library, you will be able to get an optimized version and thumb version just calling the same image using an specific URL pattern. In this blog post we cover a simple JavaScript function that lets you get picture thumbnail URL programmatically in SharePoint.

First, it’s important to say what is a thumbnail! According to Wikipedia, “Thumbnails are reduced-size versions of pictures or videos, used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words”.

It’s extremely useful when you need to develop a custom web part to present an image inside a Library and you want to save bandwidth for your users at the same time that your site has better performance too. Working with the thumbnail version of your images will let SharePoint handle cache and performance in a more efficient way, making your system more reliable and faster.

To export a list you must have a Microsoft SharePoint Foundation-compatible application

April 22, 2019 / / 0 Comments

SharePoint lists and libraries can be exported to Excel using a out-of-box functionality, but unfortunately SharePoint may present an error message like: To export a list you must have a Microsoft SharePoint Foundation-compatible application.

Putting it in simple words, it’s requiring that you must use Internet Explorer to export the list or you must update your SharePoint site (through a KB or a complete version change) because you are probably using a browser like Chrome or Firefox. . But let’s assume that you don’t have time for that and just want to have the file at that moment? Then we have a quick tip for you! So you finally will get rid of those messages “microsoft sharepoint foundation compatible application” blah blah blah.

SharePoint and Information Rights Management

February 5, 2019 / / 4 Comments

Information Rights Management or IRM is a subset of features and procedures to protect sensitive information from unauthorized access. As we know, SharePoint is document-driven, so everyone expects that platform can help you on protecting data with out-of-box options.

Hopefully SharePoint has it! Allowing you to add policies at Document Library level that persists even after the document was downloaded and isn’t at SharePoint context anymore, so I must say the IRM SharePoint is very powerful! Furthermore, it’s important to say that IRM policy will work only at library level!

Edited by me

Because I’ve had to understand the feature more deeply, considering what could be done by users that only have Read access to libraries, I’ve decided to test how the IRM feature works and then wrote a document trying to identify what are actions were available, depending on what you configure.

Edit Rendition invisible in the Ribbon

August 28, 2018 / / 0 Comments

If you happen to have the Edit Rendition invisible in the Ribbon in SharePoint and you did everything right when setting up the environment and enabling Blob Cache in your SharePoint site. Don’t worry, this blog post will help you with simple trick!

Image renditions are great when you want to provide content in different screens using specific dimensions to help people crop the image or focus in what matters most when presenting it. It’s not common to have problems with them as they add great value to your solution.

Complementing, Microsoft documentation says: “Image renditions enable you to render a single image in multiple ways. An image can be displayed in various sizes or with different cropping. The first time that an image is requested, SharePoint Server uses the specified image rendition to generate the image. When a user views a SharePoint site, the correctly sized version of the image is downloaded to the client computer. This reduces the size of the file that is downloaded to the client, which improves site performance. “.

Force Flush Blob Cache in SharePoint

August 1, 2018 / / 0 Comments

If you need to force flush blob cache in SharePoint, this script is for you! It will ensure that every file once cache will be deleted and will force SharePoint on recreating it when it sometimes becomes corrupt.

After running this script, you will get back on track and the cache will be flushed. But be cautious! This script will only affect the server where it’s being executed. In cases where you have multiple web application servers working together, the script must be executed in each server. It is necessary because each server holds its personal folder where the assets will be stored and cached.

The Blob Cache is an important feature that must be used when you have heavy traffic with lots of anonymous users, or even if you need to explore Image Renditions (we have a blog post about some problems there too). You can find over the internet a lot of content about it, but I must say that exists some undocumented stuff about the topic that may have been lost in the history and it’s just present in some old books about SharePoint.

The Script to force flush Blob Cache

All the steps below are important to get things working again. Basically our script will delete the Folder where you have configured the Blob Cache to store the files, then we will call the Flush Blob Cache method offered by the SPWebApplication object from SharePoint. Finally, the iisreset is an important step because it will ensure that the everything is rewinded and refreshed.

That’s it! I hope this script can help you getting things on track, perfoming a force Flush Blob Cache in SharePoint and serving a good SharePoint Site with awesome performance to your users.
