    ClickHeaderCellToExpand Property
    In This Topic
    When this property is true and client script is enabled, the spread will expand the row in a hierarchical view when the row header cell is clicked; otherwise, the spread will expand the row only when the expand image is clicked.
    Public Property ClickHeaderCellToExpand As Boolean
    Dim instance As SheetView
    Dim value As Boolean
    instance.ClickHeaderCellToExpand = value
    value = instance.ClickHeaderCellToExpand
    public bool ClickHeaderCellToExpand {get; set;}
    This will expand the child view without clicking on the "+" sign in the hierarchy.
