ToolStripDropDownItem.ProcessDialogKey Method

Processes a dialog key.

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

[UIPermissionAttribute(SecurityAction.LinkDemand, Window = UIPermissionWindow.AllWindows)]
protected internal override bool ProcessDialogKey(
	Keys keyData
)

Parameters

keyData
Type: System.Windows.Forms.Keys
One of the Keys values that represents the key to process.

Return Value

Type: System.Boolean
true if the key was processed by the item; otherwise, false.

This method is called during message preprocessing to handle the UP, DOWN, LEFT, RIGHT, ENTER, and SPACEBAR keys in order to navigate the hierarchy of drop-down menus.

Notes to Inheritors

When overriding the ProcessDialogKey method in a derived class, the overriding implementation should return true to indicate that it has processed the key. Derived classes will seldom, if ever, need to override this method.
