    PropertyDescription
    Gets which mouse button was pressed.  
    Gets or sets a value indicating whether the event should be canceled.  
    Gets the number of times the mouse button was pressed and released.

    Remarks
    This event fires before the grid processes the System.Windows.Forms.Control.MouseDown event, and gives the program a chance to customize the behavior of the control and optionally cancel the default handling of the mouse.
    Example
    The code below handles the BeforeMouseDown event to detect clicks on row headers and provide OLE drag and drop functionality.
