ToolStripDropDownItem.ProcessCmdKey Method

This member overrides ToolStripItem.ProcessCmdKey(Message, Keys), and more complete documentation might be available in that topic.

Processes a command key.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
[SecurityPermissionAttribute(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.UnmanagedCode)]
protected internal override bool ProcessCmdKey(
	ref Message m,
	Keys keyData
)

Parameters

m
Type: System.Windows.Forms.Message

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

keyData
Type: System.Windows.Forms.Keys

One of the Keys values that represents the key to process.

Return Value

Type: System.Boolean
false in all cases.

This method is called during message preprocessing to handle command keys. Command keys are keys that always take precedence over regular input keys. Examples of command keys include accelerators and menu shortcuts. The method must return true to indicate that it has processed the command key, or false to indicate that the key is not a command key.

The ToolStripDropDownItem implementation of this method calls the ProcessCmdKey of the DropDown if there are items in the DropDownItems collection. Otherwise, this implementation calls the base class implementation.

Notes to Inheritors

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