>>When I open a particular form, the built in VFP activity refreshes all my controls. This is normally a good thing … but in this case I have controls that during their refresh, call the refresh event of other controls to complete a cascading start up logic of my own (that includes some data manipulation). What I’m looking for is the equivalent of a data session’s NoDataOnLoad so that I can set what is effectively a “NoRefreshOnOpen” for the form.

I would have tried it already, but I don’t know how to determine that control has returned to me so that I can then set glBlockRefresh to .f. and then programatically call appropriate refreshes to get things going. That is, where would I put glBlockRefresh = .f. I’m assuming that it’s at the top of the form’s Init, but I’m not sure.

BindControls wasn’t appropriate in my case, as it blocks binding controls to ALL data sources. In some of my combo boxes I create a SQL query (that doesn’t get run with BindControls = .f.) then generates an error when the control references a field in the missing query result.

It was the key though to understanding my problem better. I now realize that I need something more selective so I’m opting for the glBlockRefresh approach in SOME of my controls.

I’m experimenting now with turning it off by putting glBlockRefresh = .f. in the Form’s Activate, or Init events, or in the KeyPress and MouseDown events.
