DataGridView.ProcessDialogKey Method

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

Processes keys, such as the TAB, ESCAPE, RETURN, and ARROW keys, used to control dialog boxes.

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

protected override bool ProcessDialogKey (
	Keys keyData
)
protected boolean ProcessDialogKey (
	Keys keyData
)
protected override function ProcessDialogKey (
	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 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.

If a key press is determined to not be an input key, it will be sent to the dialog box by this method.

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.
