Set the UltraTree.Override.ShowExpansionIndicator property to 'Always'

rtatsheridan,

The UltraTree does not do this by default.  The closest you'll be able to get is if you set UltraTree.Override.ShowExpansionIndicator to ShowExpansionIndicator.CheckOnExpand.  However, once you click the expansion indicator of a Node with no child Nodes, you will lose the expansion indicator.  If you would like to submit a feature request for the ability to display expansion indicators for all Nodes at all times, you can do so here.
