Public ReadOnly Property Level As Integer

The level.

Comments

Returns the item's level number.

The root (or highest) level is level 0, dependents are on levels 1, 2, 3 and lower. The first item in the tree control is always at level 0.

An item's level number is determined by its position in the hierarchy represented by all items. The Level property determines the "indentation" of an item.

Examples

C#

            CellClass cell = item.Cells[0];
            cell.Parts.Add(new ImagePartClass(img));
            cell.Parts.Add(new TextPartClass(ItemText));
            item.TagString = "This is a tooltip for an item labeled " + ItemText;
        }

        private void ClickCategory(ItemClass item)
        {
            if (item.Level == 0) {
                bool fWasExpanded = item.Expanded;
                if (fWasExpanded) {
                    item.Collapse(CollapseStyleEnum.All);
                    item.Cells[0].Image = m_PlusImage;
                } else {
                    item.Expand(ExpandStyleEnum.All);
                    item.Cells[0].Image = m_MinusImage;
