DataGridViewColumnCollection::CollectionChanged Event

 

Occurs when the collection changes.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
event CollectionChangeEventHandler^ CollectionChanged {
	void add(CollectionChangeEventHandler^ value);
	void remove(CollectionChangeEventHandler^ value);

Examples of collection changes include additions or removals of columns.

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the CollectionChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox::Show with Console::WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type DataGridViewColumnCollection named DataGridViewColumnCollection1. Then ensure that the event handler is associated with the CollectionChanged event.
