Comments

The Add method adds a new item at the end of the list.

New items added using the Items.Add method are always added at the end of the list. By default, new items are added at level 0. Use the Item.Level property to change an item's level. If many items have to be added or inserted, the BulkUpdate property can be used to indicate a mass-update, which is significantly faster.

Once an item has been added, the Cell.Text property can be used to change the text for any of the available columns.

Items can be inserted at a specific location using the Items.Insert method. Items can be deleted using the Items.Remove method.

When a tree control is populated using Items.Add or Items.Insert, the Items.RecalcHorizontalExtent method can be used to have the tree control calculate the optimal horizontal scrolling area so scroll bars are enabled, depending on the Scrollbars property.

If a parent item is collapsed, subsequently adding child items will automatically expand the item.
