DataGridView.ProcessKeyEventArgs Method

Processes a key message and generates the appropriate control events.

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

[SecurityPermissionAttribute(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.UnmanagedCode)]
protected override bool ProcessKeyEventArgs(
	ref Message m
)

Parameters

m
Type: System.Windows.Forms.Message

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

Return Value

Type: System.Boolean
true if the message was processed; otherwise, false.

ExceptionCondition
InvalidCastException

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.

Exception

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 DataGridViewDataErrorEventArgs.ThrowException property to true.

For more information, see the Control.ProcessKeyEventArgs 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.
