QuestionEventHandler Delegate

Represents the method that will handle the CancelRowEdit event or the RowDirtyStateNeeded event of a DataGridView.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public delegate void QuestionEventHandler (
	Object sender,
	QuestionEventArgs e
/** @delegate */
public delegate void QuestionEventHandler (
	Object sender, 
	QuestionEventArgs e
Not applicable.



The source of the event.


A QuestionEventArgs that contains the event data.

When you create a QuestionEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.

This delegate is used when implementing virtual mode in the DataGridView control.
