property Item.CaptionWidth as Long
Specifies the fixed width to display the item's caption.

TypeDescription
Long A Long expression that specifies the width to display the item's caption.
By default, the CaptionWidth property is -1. If the CaptionWidth is negative, the caption expands the size of the item to fit entirely. If the CaptionWidth property is positive, it indicates the width to display the item's caption. The Caption property specifies the HTML caption to be displayed on the item. For instance, you can use the CaptionWidth to align editors of the items. The ItemHeight property specifies the height to show the item.

How can I specify the width of the item?
