I have a WebListBox with 4 columns, totalling more than the width of the control, so the horizontal scrollbar shows.
If I go
ListBox1.ColumnCount = ListBox1.ColumnCount +1
a new column width “*” is added, but the horizontal scrollbar disappears, although the existing columns largely exceed the width of the control.
Only when I set the last column as a numerical value, would that be “0”, does the horizontal scrollbar comes back.
I am inclined to call that a bug.
