A LinesStyleEnum expression that defines the element's border, or
exLinesInvalid for the default element's border defined by the
Background(exElementBorder).
By default, the Border property is
exLinesInvalid, which indicates that the control's Background(exElementBorder)
property defines the element's border. Use the
BorderColor property to specify a different border color. The BorderPadding
property specifies the border padding. The BackColor
property specifies the element's background color. The ForeColor
property specifies the element's foreground color.
