Try something like
//Requery the detail dataset if the key field is changed in the master
dataset
TADODetailDataSet->Requery(TExecuteOptions());
Rather than closing and then reopening the dataset.
Hope this helps Nigel

I thought that a detail set (established thru MasterFields)
automatically closes and re-opens following the master one.
So its content also refreshes. But this does not happen.
After making changes in both master and detail tables, I re-opened
the master set, but did not touch the detail set. And the detail's
content showed in a db grid remains unchanged.
So I should manually reopen the detail set? And what happens
with the detail set within a period when the master is closed and
re-opened?
