Jay,
if these grids bounded relation on DE you have a master file ( eg. master customers,child orders,child orderdetails) if so ; create a property on the form eg. LcAlias and set each of grids when events thisform.LcAlias=this.recordsource and valid event thisform.LcAlias= this.linkmaster . linkmaster will be customers on each grid . your navigation allways trap LcAlias. This will solve your problem if your need like above explained.
