Performance tip for databound UI
When loading large amounts of data into a dataset table with databound UI, things can get pretty slow. One reason is that each time a row is added to the table, the databinding components will perform some work and tell the databound controls that a new record was added. To improve performance, you can suspend the binding events while the data is being loaded. The BindingSource component has a RaiseListChangedEvents property for that purpose. Here's an example how to use it:
AddressBindingSource.RaiseListChangedEvents = False
AddressTableAdapter.Fill(AdventureWorksDataSet.Address)
AddressBindingSource.RaiseListChangedEvents = True
AddressBindingSource.ResetBindings(False);
Another option is to disconnect the BindingSource component while the Fill is being executed by setting its DataSource property to Nothing and reconnect it after Fill has completed.
