Hierarchical Grid - DataSet Binding

This sample is designed for a larger screen size.

On mobile, try rotating your screen, view full size, or email to another device.

Using the ASP.NET MVC helper, you can bind the igHierarchicalGrid directly to DataSet objects. This sample demonstrates igHierarchicalGrid configured with auto-generated columns and layouts bound to DataSet object. Paging feature operates in remote mode. All of the features are inherited, so they are available in the auto-generated child layout.
