DataGridView.ProcessUpKey Method

Note: This method is new in the .NET Framework version 2.0.

Processes the UP ARROW key.

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

protected bool ProcessUpKey (
	Keys keyData
)
protected boolean ProcessUpKey (
	Keys keyData
)
protected function ProcessUpKey (
	keyData : Keys
) : boolean

Parameters

keyData

A bitwise combination of Keys values that represents the key or keys to process.

Return Value

true if the key was processed; otherwise, false.

Exception typeCondition

InvalidCastException

The UP ARROW key would cause the control to enter edit mode, but the EditType property of the new 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.

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