Simple validation of properties in EPiServer 6 using DataAnnotations with PageTypeBuilder

In EPiServer 7 you can easily add validation to pagetype properties with DataAnnotations attribute, like this:

In EPiServer 6 you can create a custom property (involves creating some classes and messing up the db sometimes), or hook up onto global page save validation event and check if property x is valid and return e.message. (

Or, you can combine the usage of hooking up onto global pagedata validation with DataAnnotaions support, then you in fact
have something similar to the EPiServer 7 way with DataAnnotations support. Just go here: Validating page data with Data Annotations.
Thank you Stefan Forsberg.

the GlobalPageValidation_Validators event can be hooked onto through Global.asax.cs like this:

Also added an <br /> in case of several errors.
Validation Error message looks like this in EPiServer edit mode:

Its a bit on the simple side; remember to include which field its connected to in the errortext, no indication is shown next to the particular field.

Now you can just use DataAnnotations validation attributes, like these:


Inherit System.ComponentModel.DataAnnotations  and override IsValid to do something more complicated with your validations.
