I have a request to validate some information on the order when adding rows to the Sales Order Pick List filter.
If the validation fails, they want a warning stating the reason and to prevent the user from adding that row to the filter. I have the validation and message part, but I’m drawing a blank on how to stop that row add.
What about changing the message to an exception?
throw new Ice.BLException("You done messed up, A-A-Ron.");
(sorry - couldn’t resist 
)
I just tested this on an EpiViewNotification.AddRow event and it kills the row being added.

This is what I ended up going with:
private void orderList_DataView_ListChanged(object sender, ListChangedEventArgs args)
{
// ** Argument Properties and Uses **
// orderList_DataView[0]["FieldName"]
// args.ListChangedType, args.NewIndex, args.OldIndex
// ListChangedType.ItemAdded, ListChangedType.ItemChanged, ListChangedType.ItemDeleted, ListChangedType.ItemMoved, ListChangedType.Reset
// Add Event Handler Code
for( int i = 0; i < orderList_DataView.Count; i ++ )
{
if( (bool)orderList_DataView[i]["OrderHeld"] )
{
MessageBox.Show("Order " + orderList_DataView[i]["OrderNum"].ToString() + " is on shipping hold and has been removed from your selection.");
orderList_DataView.Delete(i);
}
}
}

I liked the A-A-Ron. one, because of the message.
