An Entity Editor Display Template, Advanced Client Side Rendering

Ever had a list in SharePoint with a choice field that allowed multiple selections (i.e. checkboxes)? And with many things to choose from? See the picture below. In this particular case, you’d need to scroll down a page or two to see all of the choices. I’ve seen a lot of people try to solve this problem by making the choices wrap around inline instead of one per line, which is a fine solution if your choices are relatively small strings and there is a small enough number of them. But what if there are over 100 choices, and some of them are pretty big strings? That’s the problem I’m trying to solve with this Entity Editor Display Template.

Star Ratings Display Template, Advanced Client Side Rendering

In this post, I’m going to do a CSR field rendering template for a star ratings field. It’s just what it sounds like, give the user an opportunity to rate something with 0 to 5 stars, by clicking into an image of 5 stars. Under the hood it will just be a numeric field, but as much as possible I’d like the user to never see the number. Anywhere the field appears, they should see an image with the appropriate number of gold stars.

$select and $expand in SharePoint REST requests

I have used OData operators like $select, $filter and $expand in previous posts (REST in SharePoint) without any real explanation. This post is the first in a series that will rectify that by giving detailed descriptions of how to use OData operators in SharePoint REST requests. In this post, I’m going to explain the purpose and usage of two OData operators, $select and $expand.

Loading JavaScript or CSS on Every Page in a Site using JSOM (UserCustomActions)

A common question in SharePoint forums is how do I load SuchAndSuch.js on every page in the site collection (ok, let’s be honest, it’s usually how to I load jQuery on every page). This is pretty easy to do using the SharePoint client object model and setting something called UserCustomActions. In this post, I’m going to build a utility page to do just that. It will be an ASPX page (really just a text file) that you can drop in any SharePoint document library and click on to start immediately configuring UserCustomActions at either the site or the web level. It has no dependencies. It is a self contained page with only HTML and pure JavaScript.

CSR on Steroids and the Amazing Technicolor Text Boxes

First things first, I want to apologize, because what I’m going to build in this post is pretty hideous. I’m going to introduce the concept of hooking up SharePoint CSR by type, rather than by internal field name (as most examples show).

By way of background, yesterday I was trying to override the Client-side Rendering (CSR) of a Url field to allow it to take non-standard protocols like notes://. I didn’t feel like creating a site column so I applied it to the OOB site column called Url. So I setup my overrides like so:

Here I’m overriding the rendering for the field called Url in all forms and views, right? Not so fast sparky! This worked a little too well. My override was getting called for other fields of type SPFieldUrl on the page that weren’t named Url. Ugh! Stepping through clienttemplates.js in the debugger, it quickly became apparent what was going on. In the fields object, you can specify CSR by internal field name, like I’ve been doing in previous posts in this series, but you can also specify CSR by type of field (using the client-side field type, so for instance Text for SPFieldText). This replaces the default rendering for all fields of that type.

That’s actually pretty cool, but the problem with it is that if you have a field whose internal name is the same as a field type, there is no way for you to override just that field. Bad Microsoft, programmer no donut! The rest of this post is going to be a quick demo I put together to demonstrate this functionality. I haven’t seen anything in the documentation for CSR, or any examples, that explain this functionality. Of course, the documentation for CSR is pretty thin.

Managing Role Assignments/Permissions with SharePoint REST Part2

In my last post I described many of the REST endpoints available in SharePoint to manage role assignments. In this post, I will provide a concrete example of using these endpoints in a provisioning-like scenario. I say provision-like because real provisioning scenarios tend to be very specific and one-offs (i.e. I need 7 sites, each with 5 lists and 3 groups, based on a naming convention by organization, and these permissions, and blah and blah and blah). Such specific requirements can’t be written into a one size fits all solution, so I’m just going to mimic them by creating a whole bunch of role assignments, and then deal with some of the issues of initiating a bunch of ajax calls in a short period of time.

Managing Role Assignments/Permissions with SharePoint REST

To assign permissions in SharePoint, you make one or more role assignments, which requires three things:

  • Some kind of handle for a securable object. That’s basically a site, list, library, folder, document, or item.
  • The principal id for something to which roles can be assigned. That’s either an Active Directory user or security group, or a SharePoint group.
  • The id of a role definition. Like ‘Full Control’ or ‘Edit’ or ‘Contribute’. This is basically a named collection of granular permissions that are defined at the site collection root and can be assigned to a securable object in that site collection.

In this post, I’m going to explain the REST service calls required in order to make role assignments to SharePoint securable objects. I will show the calls using jQuery’s ajax (because I’m working through them in the console and the console won’t resolve promises). I’ll follow up with a post with some demo code pulling it all together and probably using fetch.
