I have a requirement to pre-populate fields from an external source.
Is there a way to hook into a pipeline to achieve this? I'm thinking something similar to how Sitecore can populate the fields by query string by key value. i.e. when the form loads I pull my data from my external source and set the values of the fields by matching on field names.
You can obviously defined save actions for a form, is there a way to define a 'On Load' action?
I've seen another answer on here suggesting to create custom individual fields, but I don't really want to create a bunch of fields that individually get the data it needs; I'd rather do it from a higher level in one operation.
