Hi Michael,
Thank you for using Syncfusion products.
We have illustrated the data binding with ObjectDataSource in
TreeView control, Please refer it from the following links,
http://asp.syncfusion.com/demos/ui/Tools/TreeView/DataBinding/cs/TreeViewDataBinding.aspx
If the issue with the TreeView control persists, could you
please share the sample? This would help us to serve you better.
Let us know if you have any other queries.
Regards,
Ezhil.S
