DataGridView.OnColumnStateChanged Method

Raises the ColumnStateChanged event.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

protected virtual void OnColumnStateChanged (
	DataGridViewColumnStateChangedEventArgs e
)
protected void OnColumnStateChanged (
	DataGridViewColumnStateChangedEventArgs e
)
protected function OnColumnStateChanged (
	e : DataGridViewColumnStateChangedEventArgs
)
Not applicable.

Parameters

e

A DataGridViewColumnStateChangedEventArgs that contains the event data.

Exception typeCondition

InvalidCastException

The column 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.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

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