Definition

protected:
 override bool ProcessKeyPreview(System::Windows::Forms::Message % m);
protected override bool ProcessKeyPreview (ref System.Windows.Forms.Message m);
override this.ProcessKeyPreview :  -> bool
Protected Overrides Function ProcessKeyPreview (ByRef m As Message) As Boolean

Parameters

m
Message Message Message Message

A Message, passed by reference, that represents the window message to process.

Returns

true if the message was processed; otherwise, false.

Exceptions

The key pressed would cause the control to enter edit mode, but the EditType property of the current cell does not indicate a class that derives from Control and implements IDataGridViewEditingControl.

This action would commit a cell value or enter edit mode, but an error in the data source prevents the action and either there is no handler for the DataError event or the handler has set the ThrowException property to true.

Remarks

For more information, see the Control.ProcessKeyPreview method on the base class.

Notes to Inheritors

When overriding this method, a control should return true to indicate that it has processed the message. For messages that are not processed by the control, return the result of the base version of this method.
