Use when binding controls using DataBindings.Add, setting up BindingSource with DataSource, implementing INotifyPropertyChanged for automatic UI updates, creating two-way bindings between controls and data objects, using BindingSource.Filter or BindingSource.Sort, implementing master-detail relationships with related BindingSources, handling binding validation with ErrorProvider, or troubleshooting binding update issues and performance. Also triggers for "BindingSource", "DataBindings.Add", "INotifyPropertyChanged WinForms", "two-way binding", "ErrorProvider", "master-detail binding", "BindingNavigator", "DataSource binding", and "WinForms data binding".
