ToolStripSplitButton.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 ENTER and SPACEBAR keys in order to raise the Click event. However, if the ToolStripSplitButton is not enabled, this method calls the base class implementation instead.

This method is called only if the IsInputKey method indicates that the item is not processing the key.

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.
