trying to capture rowchanged event for datagrid without success

[astro]

I've tried the following without success.......

AddHandler DS1.Tables("dia l").RowChang ed, AddressOf after_row_inser t
AddHandler CType(Me.dgDial s.DataSource, DataTable).RowC hanged,
AddressOf after_row_inser t
the 2nd raises an "invalid cast" error, neither redirects to my
'after_row_inse rt' event.
Any ideas why this is not working?
Thanks

Astro,

What does this look like
dgDials.Datasou rce = ????

the datasource is a dataview....... ..

Astro,

You can not use an event from a datatable with a dataview, however see this
sample, it will have the same (better) effect.

Currencymanager event

Your fine example works when the object of interest is the dataview....but I
am interested in a child table's row change event....

let me explain the scenario:

I have a customer table. I have a dataview for this table that my
textboxes, comboboxes, etc. are bound to. This is not a defaultview, it is
a custom dataview that I filter, sort and searh on.

I have a datagrid which is bound to the relation between the dataview and a
child table. I want to trap the rowchange event of this datagrid. It's
datasource is dv1 (my dataview), it's datamember is the relation between the
parent and child table: companydial.

I think the currenyManager idea will work.....just don't know how to point
it to this 'child' datagrid.

Any ideas?

Almost the same as in your first post in this thread.

Dim cma As CurrencyManager = DirectCast _
(BindingContext (DirectCast(dgd ials.datasource ,dataview)),
CurrencyManager )

I changed it here so watch typos,

I hope this helps,

thanks - that works for the rowchange on the dataview...but not when I
change rows in the dial datagrid....

Astro,

This does something more than the rowchange in a datagrid. This fires when
there is a selected rowchange in the datagrid even when the datarow in the
table is not changed.

thanks for your diligent replies Cor........

I"m taking a break from this approach....... ...in working through this
problem I think I have a better idea of the coupling between the grid and
the underlying data table. It seems to be better to trap & save the row
changes at the table.rowchange s event then hooking into the grid events via
a reference to a currency manager..
