Scott Shearer and I were at SharePoint Saturday VA Beach this past weekend, which was an excellent event. Scott did a few different presentations including one on SPEasyForms, which drew a pretty big crowd and was pretty well received. After the presentation Scott opened the floor for questions, which quickly got a little deeper into the implementation details than he was expecting so I got up and fielded some questions. One of the questions was if you pass in request parameters, can SPEasyForms initialize form fields from the values? The answer was no, but it wouldn’t be that hard to implement and this is a very common request in SharePoint forums. In fact, I’m going to need this kind of functionality for some of the improvements I envision for SPEasyForms in the future.

Extending SPEasyForms Visibility Rules
This is going to be a fairly short post, because there isn’t that much to extending visibility rules. SPEasyForms visibility rules have two extension points, state handlers and comparison operators. The built-in state handlers and comparison operators in v2014.01 are shown in the two drop down lists on the add/edit visibility rule dialog box shown below:
This post is going to explain how to extend the visibility rules by adding the following functionality:
- Comparison operators for >, >=, <, <=, and !=
- State handlers to highlight a field in various colors
First SPEasyForms Plug-in, DefaultToCurrentUserAdapter
To demonstrate writing a plug-in for SPEasyForms, I’m going to write a pretty simple adapter that can be applied to user fields and adds the functionality to default the field value to the currently logged on user on new forms. It’s not just simple enough to provide a good sample for explaining creating plug-ins, it’s also something that customers ask me for pretty frequently. This post is going to explain the JavaScript behind the plug-in. The source code download will be a full-fledged no code sandbox solution, but if you need an explanation of the solution or packaging see my previous post Anatomy of a No Code Sandbox Solution; I’m not going to explain that again here.

SPEasyForms: Why is my Form so Jumpy?
As in why does it look just like an OOTB form for several seconds, then all of the sudden it is redrawn with tabs, and hidden fields, and all of the stuff I configured SPEasyForms to do? This annoys me! my users! my boss! how do I fix it?
