Hi Greg I should have mentioned that I am playing with the BindingNavigator control to implement a data entry screen, and a grid to implement a browse screen.
I want to click the grid and have the Navigator move to the record I selected in the grid. I thought BindingNavigator.DataSource.Find would be the way to do it, is there a better way?

The generic List class does not implement IBindingList. I'm not sure who is asking for the IBindingList, but it has to be the Find method. Ah yes, only DataSet, DataTable and DataView implement it. I think you're misusing the BindingSource. I usually put it "between" the real data source collection and a control like a grid where it gives me a bit more flexibility in UI binding. If you want to find certain Customers that I'd search the actual List, not the binding source. Customer cust = custList.Find(c => c.CustomerID == 666); or Customer cust = (from c in custList where c.CustomerID == 666 select c).SingleOrDefault(); Greg __________ Information from ESET NOD32 Antivirus, version of virus signature database 6292 (20110713) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
