I would have thought this would show the properties whether exposed or not.

If you type in the property name (preceded with a .) and then click the Tab key, does this fill in the label text? (if so this means it has recognised the property).

Laurence,

I am not getting what you are trying say, I am asking to add column dynamically, when the user run's report and click on the edit report button.

Please find the attachment of query.

Ah, sorry I misread your question. I thought this was related to building a report definition.
