You can set three types of properties for the TreeView DataWindow:
General properties
TreeView level properties
Detail band properties
In the sample DataWindow shown in “Creating a new TreeView DataWindow”, different tree node icons display for collapsed and expanded levels. The icons are also different for each level. You specify images for these icons as TreeView level band properties.
The sample DataWindow also displays a tree node icon next to every row in the detail band. You specify an image for this icon as a detail band property.
Tree node icons do not display by default. After specifying images for icons, select the Use Tree Node Icon general property.
