ListColumn.WidthExpression Property

Syntax

WidthExpression as String

Column width as a string expression that can include the percent sign, a decimal point, or blanks. Width can be specified as a value in pixels, a percentage, or a relative length.

To obtain the absolute width of a column specified using percent or a relative length, call WidthActual. If you use * or %, the actual width will vary as the width of the ListBox changes.
