Using xdExtension to call function

[em]

hi,
I would like to call a function written in managed code from within an
expression box by using the xdExtension:function call . But I get an error
saying, that "the name space prefix xdExtension is not declared" - where do I
have to do that ?
Thank you!

high quality of your "InfoPath Dev Nugget" !

As best as I can tell there is zero support for xdExtension in Expression Boxes. Too bad too. I'd love to use it there myself.

You can use it on Conditional Formatting, and with a manual update to the manifest.xsf file, you can use them with Rules. But I've never found a way to use them with Expression Boxes yet. If anyone else knows how to do this--do tell!

For getting xdExtension to work with rules, check out the InfoPath Dev Nugget titled, "Use Code to Determine a Rule Condition".

You can use it if you edit the XSL yourself. I can't remember if you
have to wrap it in xdpreserve in order to load/roundtrip the custom
XPath in design mode.
