BindingSource, set datasource and then set a NEW datasource

I've got a BindingSource with only 1 o开发者_C百科bject as the DataSource.

I bind on some values on the datasource. That works perfectly.

BUT.

When I do:

bindingSource.DataSource = new Foo () { Bar = "..."; } 

this is not reflected through the UI.

is there a way to force an update?

I tried resetbindings on the controls that bind to the datasource but no luck.

Have you tried calling ResetBindings() on the BindingSource instead?
