<br />
The unique tag and column of the item string displayed in the top left corner of the tree control. Use this property to read or change the top item, or use it to read or change the leftmost column of information displayed.<br />
<br />
If you wire a tag of <code>TREE_COLUMN_HEADERS</code> or <code>TREE_ALL_ROWS</code> or a column of <code>-2</code> to this property, the property returns an error. If the tree control contains no items, this property returns an error.<br />
<br />
This property returns the tag and column of the item string at the top left corner of the visible tree window, which is not necessarily the top left element of the tree. To access the top left element, wire a value of 0 to the [[Active Cell:Active Column Number]] property and to the [[Active Item:Row Number]] property.<br />
