System.Windows.Forms.ToolStripDropDown.ProcessDialogKey Method

Processes a dialog box key.

Syntax

protected override bool ProcessDialogKey (Keys keyData)

Parameters

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

Returns

true if the key was processed by the control; otherwise, false.

Remarks

This method is called during message preprocessing to handle dialog box keys, such as TAB, RETURN, ESCAPE, and arrow keys. This method is called only if the Control.IsInputKey(Keys) method indicates that the control is not processing the key. The ToolStripDropDown.ProcessDialogKey(Keys) simply sends the character to the parent's Control.ProcessDialogKey(Keys) method, or returns false if the control has no parent. The System.Windows.Forms.Form class overrides this method to perform actual processing of dialog box keys. This method is only called when the control is hosted in a Windows Forms application or as an ActiveX control.
