WebBrowserBase.ProcessDialogKey Method (Keys)

 

This API supports the product infrastructure and is not intended to be used directly from your code.

Processes a dialog key if the WebBrowser ActiveX control does not process it.

Namespace:   System.Windows.Forms
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.

Return Value

Type: System.Boolean

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

This 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 WebBrowser ActiveX control does not process the key. In this case, this method delegates the call to the base Control.ProcessDialogKey method.

Notes to Inheritors:

When 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.

UIPermission

for all windows for inheriting classes to call this method. Associated enumeration: AllWindows value of UIPermissionWindow.
