Episerver Forms: Avoiding spam with a honeypot
Spam comes in many forms and can be really annoying. Often, when you put a form on your website it will be found by spam bots that will post lots of spam in the form. A common defense is CAPTCHA's, but they are annoying the real users and typically not WCAG compliant. Here, I'm showing a simple Episerver implementation of another approach that works wonders for me - the honeypot.
Reading very large gzipped json files in c#
This is a little code snippet that I often find quite handy. It's a piece of c# code that opens a gzipped json file and iterates through the items in it. Since it takes it piece by piece (as opposed to loading everything in memory) it's can pretty much handle files of any size.
Showing the right block types at the right time
Often, it can be handy to have very exact and dynamic control over what editors can see or do. One of my weapons of choice for this is the good, old and trusted Virtual Roles. In this scenario we have a multi-site Episerver, where some of the block types it should only be possible to use on one of the sites.
Enrich Episerver Forms with additional system fields
Episerver forms adds a couple of system columns to each form submission when you export the submissions. But it happens that the people that need the form submission reports want additional data - for example the url of the page the form was on - and for some reason they don't know all Episerver page Guids by heart.
Attribute to set XHTML property settings in Episerver
A pretty normal task is to have an XHTML property that uses only a very specific subset of the normal TinyMCE functionality. For example a text field that also allows the editors to create links - but nothing else. I came up with what I think is an elegant solution here.
Episerver Forms: Adding custom validators to existing elements
It's easy to extend Episerver forms with custom validation types. But it's a little bit harder to add the new validation types to the existing elements. In this blog post I'll add an ultra simple letter-only validation option to the existing TextboxElement.
