I'm working through the binder stuff trying to get a handle on it...
I have setup a master-detail dataset and have a couple of textboxes from the
master along with a datadgrid for the child data.
I have a navigation pallete with the usual arrows. All arrow btn's are
handled by the same handler.
Before moving off the current record I do the following:
BindingContext( Me.DataSet11, "table2").EndCu rrentEdit()
BindingContext( Me.DataSet11, "table1").EndCu rrentEdit()
'deal with current row state 1st
checkRowState(s ender, e)
CheckRowSTate looks at the rowstate and calls the SaveRecord routnine if
needed.
Select Case mbinder.Current .row.rowstate
Case DataRowState.Ad ded
Call saveRecord()
Case DataRowState.Mo dified
Call saveRecord()
End Select
Select Case mbinder2.Curren t.row.rowstate
Case DataRowState.Ad ded
Call saveRecord()
Case DataRowState.Mo dified
Call saveRecord()
End Select
The problem i'm having is this: after changing a value in the child
(datagrid) description field the rowstate remains unchanged on the 2nd or
greater master record. If I make a change to the child rec on the 1st
master the rowstate is 'modified' as expected.....
at this point i'm just bewildered..... ........

Astro,
I am afraid that I don't understand your problem, however, a rowstate
reflects only the state of the changed datarow, where it is not important if
this is a child or a master.
To get more answers, I give you the advice to past in next time your code
first in a notebook copy it back and past it in a message. Now it is hard to
see in most newsreaders what your code looks like.
I hope this helps anyhow

Thanks Cor -- )
I am trying to trap state changes for a child table on a form when from
'unchanged' to 'modified' or 'added.' The code I am using does not do this.
I will repost it here:
form load:
========
cmT2 = CType(Me.Bindin gContext(Me.Dat aSet11.Tables!t able2), CurrencyManager )
custom SaveRecord event:
=============== ====
cmT2.EndCurrent Edit()
Select Case cmT2.Current.ro w.rowstate
Case DataRowState.Ad ded
Stop
Case DataRowState.Mo dified
Stop
End Select
Before the postion changes on the form's master record, the 'saverecord'
code is called. When I make changes to the datagrid - which is populated by
the 'child' table and linked via the 'datamember' property using the
'table1table2' relation - and then move to another 'parent' record the
saveRecord event is called does not report an 'Added' or 'Modified' state in
the child table.
any ideas?

There is a chance you're getting the wrong CurrencyManager and so the wrong
Current DataRowView. You have to use the same DataSource/DataMember that
you used for binding to get the CurrencyManager .
Eg.:
detailGrid.Data Source = DataSet11
detailGrid.Data Member = "master_table.m aster_to_detail _relation"
cmT2 = DirectCast(Bind ingContext(Data Set11,
"master_table.m aster_to_detail _relation"), CurrencyManager )
A more generic way:
cmT2 = DirectCast(Bind ingContext(deta ilGrid.DataSour ce,
detailGrid.Data Member), CurrencyManager )
Also, if your detail table can contain multiple detail rows for each master
row, then you might want to use detailTable.Get Changes() or
detailTable.Sel ect(), because the user could have changed multiple detail
rows before navigating master rows.
HTH,

What's the difference between RowState & DataViewRowState?
If I am not mistaken, RowState pertains to DataTable whereas
DataViewRowState pertains to DataView but the "Select" method of the
DataTable uses the DataViewRowState as the 3rd parameter & not
RowState. I am getting confused between the two!
Please correct me if I am wrong.
