You should implement this interface when your component has initialization dependencies on other components that also implement the System.ComponentModel.ISupportInitializeNotification interface. You can check to see if the dependent components have completed initialization by checking the ISupportInitializeNotification.IsInitialized property.

System.ComponentModel.ISupportInitializeNotification is implemented by the System.Windows.Forms.BindingSource and System.Windows.Forms.ListControl types.
