Hi,

In order to bind the RadGrid to a List<> object an approach similar to the one illustrated here could be used. You could bind it directly to the List<>.

The RadGrid and its GridTableViews could be bound to an instance to any of the following types:

• DataSet, DataTable or DataView
• Array of DataRow
• Any object collection that implements the IListSource, IList, IEnumerable, or ICustomTypeDescriptor interfaces

In a hierarchical grid detail tables have to be bound separately from their parent tables, using separate data source. When binding detail tables, you also have to manage the relationship of the records in the detail data source to the parent table. This could be done declaratively or using DetailTableDataBind event.

I hope this information would be helpful to you.
