Oscar:

I use the Janus Gridex of Janus Systems http://www.janusys.com/janus/library/ (look in products) works with ADO and is relatively easy to implement in VFP, you can download demo and if you like the control, I can help with the code to implement it.
Something of interest is that is made in Querétaro, Mexico.
