DataGridView.OnRowStateChanged Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

DataGridView.Methods.cs

Raises the RowStateChanged event.

C#

protected virtual void OnRowStateChanged(int rowIndex, System.Windows.Forms.DataGridViewRowStateChangedEventArgs e);

Parameters

rowIndex

Int32

The index of the row that is changing state.

e

DataGridViewRowStateChangedEventArgs

A DataGridViewRowStateChangedEventArgs that contains the event data.

Exceptions

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.

Remarks

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

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(Int32, DataGridViewRowStateChangedEventArgs) in a derived class, be sure to call the base class's OnRowStateChanged(Int32, DataGridViewRowStateChangedEventArgs) method so that registered delegates receive the event.
