A double-click is determined by the mouse settings of the user's operating system. The user can set the time between clicks of a mouse button that should be considered a double-click rather than two clicks. The ToolStripItem.Click event is raised every time a control is double-clicked. For example, if you have two event handlers for the ToolStripItem.Click and ToolStripItem.DoubleClick events of a System.Windows.Forms.Form, the ToolStripItem.Click and ToolStripItem.DoubleClick events are raised when the form is double-clicked and both methods are called. If an item is double-clicked that does not support the ToolStripItem.DoubleClick event, the ToolStripItem.Click event might be raised twice.
