Hi,
I just tried to render a TreeGrid using one of your examples.
The result I achieved is an empty Grid with many rows and empty cells.
I worked a little and discovered that this behavior seems to happen when there is the UnobtrusiveJavascript enabled.
If I disable this flag the data appears in the treeGrid.
I need to use the unobtrusive feature enabled because I am using a Treeview in another page with Drag & Drop that works only with that flag enabled.
I tried to disable the UnobtrusiveJavascript flag for only a page but doesn't work.
I'll be glad to know if there is a workaround.
Thanks
