DataGridView.OnRowStateChanged Method

Raises the RowStateChanged event.

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

protected virtual void OnRowStateChanged(
	int rowIndex,
	DataGridViewRowStateChangedEventArgs e
)

Parameters

rowIndex
Type: System.Int32
The index of the row that is changing state.
e
Type: System.Windows.Forms.DataGridViewRowStateChangedEventArgs
A DataGridViewRowStateChangedEventArgs that contains the event data.

ExceptionCondition
InvalidCastException

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