Getting EPiServer CMS6 to run under Asp.Net 4.0

There’s a couple of gotchas for getting EPiServer to run under .Net 4.0

New default ClientID generation scheme in .net 4 disrupts EPiServer’s javascripts

If you find youself getting the following javascript exception when creating pages or expanding nodes in the edit tree in episerver:

error: the target Fullregion$explorertreeview$treeview for the callback could not be found or dit not implement icallbackeventhandler

The solution is to add the following attribute to web.config: under configuration > system.web > pages : ¬†clientIDMode=”AutoID”

You can scope this to only be applied on the util and UI locations if you don’t want the old school ID generation scheme applied globally


Validation is more strict in .net 4.0

When editing pages and submitting rich text content containing tags you might get complaining to you that you need to turn off eventvalidation, but in addition you also need to instruct 4.0 to use¬†<httpRuntime requestValidationMode=”2.0″ /> under configuration > system.web
