For avg1.exe demo (AdvColumnGrid), the first option [All], specially for columns CC and Country does not return any values.

The standard filter entries in the demo application work correctly. But the basic state without filtering cannot be set back. It should be possible to turn off the filter for a given column. For that purpose, setting the filter to [All] logically should work in your demo application. The problem with the application is that it discards all data instead of releasing it.
Do you have an answer to that?

I checked the demo and a small issue slipped in the demo.
For the CC and Country column filter specification, change first filter condition
[All]
to
[All]=*
