DataGridView.OnReadOnlyChanged(EventArgs) Method

Definition

Raises the ReadOnlyChanged event.

C#
protected virtual void OnReadOnlyChanged(EventArgs e);

Parameters

e
EventArgs

An EventArgs that contains the event data.

Exceptions

The control changed from read-only to read/write, enabling the current cell to enter edit mode, but the EditType property of the current cell does not indicate a class that derives from Control and implements IDataGridViewEditingControl.

Remarks

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

The OnReadOnlyChanged 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 OnReadOnlyChanged(EventArgs) in a derived class, be sure to call the base class's OnReadOnlyChanged(EventArgs) method so that registered delegates receive the event.
