How to: Raise Change Notifications Using the BindingSource ResetItem Method

Some data sources for your controls do not raise change notifications when items are changed, added, or deleted. With the xref:System.Windows.Forms.BindingSource component, you can bind to such data sources and raise a change notification from your code.

Example

This form demonstrates using a xref:System.Windows.Forms.BindingSource component to bind a list to a xref:System.Windows.Forms.DataGridView control. The list does not raise change notifications, so the xref:System.Windows.Forms.BindingSource.ResetItem%2A method on the xref:System.Windows.Forms.BindingSource is called when an item in the list is changed. .
