ToolStripDropDown.ProcessDialogKey(Keys) Method

Definition

Processes a dialog box key.

protected:
 override bool ProcessDialogKey(System::Windows::Forms::Keys keyData);
protected override bool ProcessDialogKey (System.Windows.Forms.Keys keyData);
override this.ProcessDialogKey : System.Windows.Forms.Keys -> bool
Protected Overrides Function ProcessDialogKey (keyData As Keys) As Boolean

Parameters

keyData
Keys

One of the 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 IsInputKey method indicates that the control is not processing the key. The ProcessDialogKey simply sends the character to the parent's Control.ProcessDialogKey method, or returns false if the control has no parent. The 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.
