Hi,
Look at this article, it does exactly what you need.
DataGridView with Detail Edit Form - VS 2005[
^]
there is a datagridview in the sample the uses a BindingSource bound to a dataset
Friend WithEvents OrdersBindingSource As System.Windows.Forms.BindingSource
(...)
Me.OrdersDataGridView.DataSource = Me.OrdersBindingSource
Now in the form that edits the record, comment out
Me.Close()
You will see that each time the record is committed to the database the grid in the parent form refreshes itself automatically.
Valery.
