Hello,

I've recently encountered a problem with using SDAC (and MyDAC). If I connect a grid control to the Query (via DataSource) I get the OnFocusedRowChanged event (in grid) fired 3 times after I use Query.Open().
I've found out that other DataSet components that I use don't produce this problem so it is related to SDAC. This can be easily reproduced by testing TDataSource.OnDataChange and TDataSource.OnStateChange.

TMsQuery.Open() fires: DataSet.Open() should fire: I'm not sure, but I think that this problem wasn't always present in SDAC. Please check this because I'm doing intensive calculations when the selected record changes and right now they are done 3 times instead of once.

Best regards,
Crafty

Please, set the SendDataSetChangeEventAfterOpen global variable to False before opening a TMSQuery, and inform whether this fixed the behaviour.
This variable is declared in the MemDS unit.

Hello Antaeus,

Yes, with this option I get the normal behaviour (one call to OnFocusedRowChanged). Is this a temporary solution?

Regards

We are investigating this problem. Meanwhile you should use this solution in your applications.
