 virtual void OnColumnAdded(System::Windows::Forms::DataGridViewColumnEventArgs ^ e);

protected virtual void OnColumnAdded (System.Windows.Forms.DataGridViewColumnEventArgs e);

abstract member OnColumnAdded : System.Windows.Forms.DataGridViewColumnEventArgs -> unit

Protected Overridable Sub OnColumnAdded (e As DataGridViewColumnEventArgs)

Parameters

e: DataGridViewColumnEventArgs

A DataGridViewColumnEventArgs that contains the event data.

Exceptions

ArgumentException

The column indicated by the Column property of e does not belong to this DataGridView control.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnColumnAdded method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnColumnAdded(DataGridViewColumnEventArgs) in a derived class, be sure to call the base class' OnColumnAdded(DataGridViewColumnEventArgs) method so that registered delegates receive the event.
