Thanks for the report - nearest (today) update of FlyGrid.Net will contain corrected docs.
So I throw in the towel with the docs, and go to the demo source code -- which doesn't compile after being converted to .Net2. Luckily, this problem is easy enough to correct.
You can open VS2005 solution from the Programs Menu, just choose
9Rays.net\\FlyGrid.Net\\Samples\\C# Samples (VS2005) or
9Rays.net\\FlyGrid.Net\\Samples\\VB.Net Samples (VS2005) project.
