ListBox.ColumnWidths

A list of comma separated values, with each value controlling the width of the associated column. A value can be an absolute value (in pixels), a percentage, or a relative length expressed as i* where i is an integer.

Syntax
ColumnWidths as String

# Notes

If you use percentages, you can use non-integer values to specify fractions of a percent, e.g., 43.52%. The percentage value can be greater than 100%.

If you use pixels, the last column doesn't grow to the size of the rest of the ListBox. Without any column width specifications, the headers will be divided evenly. If there are fewer column widths specified than the total number of columns, the remaining columns will divide up the remaining width equally.

An element with a length of "3*" will be allotted three times the space of an element with length "1*". The value "*" is equivalent to "1*" and can be used to mean "fill the remaining space."

You can use a mixture of pixels, percentages, and relative lengths. Column widths specified in pixels are guaranteed to have the specified width. Column widths specified in percentages are guaranteed to have that percentage of the visible width of the ListBox. The column widths specified using the * divide up the remaining width proportionally. For example, if there are four columns, the specification

20, 20%, *, 2*

gives 20 pixels to the first column 20% of the total to the second column, and the last two columns divide up the remaining width in the ratio of 1:2, with the last column getting any remaining fractional pixels.

Unrecognized or unsupported expressions (e.g. '2@')for the column width properties will result in an UnsupportedFormatException. The message of this exception describes in English what went wrong.

Resizing a column will resize the value of the expression. If you resize the ListBox, both the percentage and relative lengths recompute their actual widths. There are two resizing "modes"; see notes.

Header End caps are added for any additional unused space if headers are used. Header end caps do nothing when clicked.
