Hi Brian Dahl,
Thank you for contacting Syncfusion support.
We have checked your query “Missing Items property in TabNavigation control”. We were unable to reproduce the reported issue. Also, we have prepared the sample in which we have added items in TabNavigation control using its Items property. Please download the Sample and video from the below location.
