Dear All / Jason

Hope you can help me. Last posted 2004/05/17
I've been struggling with this one ever since.
I'm sending it in private to Jason as well. Hope he can help. (Please
Jason .. Help me with this one PLEEEESE)
I've added code from a test app below.
I'm using a generator for the ID field of a table, and I'm using before,
and after events to assign the ID field.
See the source below.

NB! NB! NB!
If I don't use before event, but enter the ID physically, then all works
just fine!!

So then I narrowed it down to actually assigning the ID field to the
Query.
When that is done, the last column's data on the grid is lost.

So, I can only assume that once I have entered the last column in the
grid, then click post, the before event is fired, then the ID field is
assigned to the Query, then the data is lost in the grid.

Here is the description of what is happening as originally posted

I've an IB_Grid, a IB_UpdateBar, and a IB_Query.

When I display data on the grid, and insert a new record, I then type
the data in on the collums on the grid.
The last collum I enter data into, is not moved out of, and I then click
the post button.
The record is posted to the grid, but the data entered in the last
column is not posted, it is left <NULL>. (Does not have to be a specific
column, any column that is not tabbed out of.)
If I then edit the record, and reenter the data for the column, it then
posts it correctly.
If I enter data for the column on an insert, and then move out of the
column to the say previous column, same row, and then post the data, it
is then accepted, and shows.

Why on earth must I first tab out of the column to get the data to be
saved.
Surely I can enter the data for the column, and then just click on the
post button.

Please all help will be appreciated.

Regards

Adrian

When this line is executed, then the last column not tabbed out
of is lost!

end
Else If (IB_UpdatebarPERFORMANCE.FocusedButton = ubEdit) then
IPERFId := IB_QueryPERFORMANCE.FieldByName('PERFORMANCEID').AsInteger
{This line is entered so that if click on text to edit without
first placing in
edit state will still secure the PERFORMANCEID to return to the record
after the post}
Else If IB_QueryPERFORMANCE.State = dssEdit then
IPERFId := IB_QueryPERFORMANCE.FieldByName('PERFORMANCEID').AsInteger;
end;

function TForm1.GetNewID(const aTable: String): Integer;
begin
{ call the stored procedure to get a new ID }
PROCGETNEWID.Unprepare;
PROCGETNEWID.ParamByName('TABLENAME').AsString := AnsiUpperCase(aTable);
PROCGETNEWID.ExecProc;
Result := PROCGETNEWID.FieldByName('NEW_ID').AsInteger;
end;

end.

Jason .. should I not be using before after events with a generator to
assign incremental Id fields in my tables.
Is there a more elegant method.
I don't want to redesign my entire application.

Thanks for all help!!!!!!!!!!!!!!!!

DESPARATE!!!!
