ToolStrip.ProcessDialogKey Method
Processes a dialog box key.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
[UIPermissionAttribute(SecurityAction.LinkDemand, Window = UIPermissionWindow.AllWindows)] protected override bool ProcessDialogKey( Keys keyData )
Parameters
- keyData
- Type: System.Windows.Forms.Keys
One of the Keys values that represents the key to process.
The ProcessDialogKey method is called during message preprocessing to handle dialog characters such as TAB, RETURN, ESCAPE, and arrow keys. This method is called only if the IsInputKey method indicates that the control is not processing the key. The ProcessDialogKey simply sends the character to the parent control's ProcessDialogKey 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 an ActiveX control.
Notes to InheritorsWhen overriding the ProcessDialogKey method in a derived class, a control should return true to indicate that it has processed the key. For keys that are not processed by the control, the result of calling the base class's ProcessDialogChar method should be returned. Controls will seldom, if ever, need to override this method.
