How to bind a nested enumerated control from an ObjectDataSource
If you have multiple levels of enumerated controls (ie. Repeaters, ListViews) that need to be databound to properties of a bound DataItem, use the below DataSource property on the nested control…
DataSource='<%# DataBinder.Eval(Container.DataItem, "Tags")%>'
This can be required if you have some sort of hierarchical data. My example came up while loading article posts that contained a list of tags.
