Hello,

You could use Hierarchical mode in WebGrid without using ISDataSource control.
We also already provide samples that show how-to bind hierarchical in WebGrid without ISDataSource control.

To see the samples, just simply go to WebGrid Tutorials solution in your Start Menu (WebGridTutorial.png).
[Start Menu -> All Programs -> Intersoft WebUI Studio 2012 R2 -> WebGrid 8 -> C# Tutorials Solution].

In WebGrid Tutorials solution, go to V3.1 -> BindingHierarchical.aspx (WebGridBindingHierarchical.png). In this sample, we use InitializeDataSource server side event to bind the WebGrid to Table Adapter.

Hope this helps. Thank you.

Regards,
Hans.
