The Item property retrieves an item from the toolbar. The Format property adds/removes items in the toolbar control. The Caption property specifies the item's HTML caption. The ToolTip property specifies the item's tooltip which is shown when the cursor hovers it. The UserData property associates any extra data to an item. The Enabled property enables or disables the specified item. The Select event notifies your application once the user clicks / selects the item.
