Yes, we are almost ready with that and expect to release this feature (subgrid in grid) Monday. We will let you know here when we are ready, the updates will show on our ASP.NET site here:
Let us know what you think. We believe it turned out pretty well (in terms of code complexity) – just one line of C# code, one new grid property (SubGridMode.Parent, SubGridMode.Child) and a couple of lines of javascript. You can see all code implementation details in the code tabs below the example.
We are also finishing up the documentation and it will be available on the site later this week.
Just a quick update, we've changed the API a bit and moved everything in the HierarchySettings collection. HierarchyMode controls if grid is parent, child (or both, for example 2-nd level grid in a 3 level hierarchy).
We've optimized even more and if you check out the Hierarchy example here:
You will see that we have a complete 3 level hierarchy based on Northwind (Customers -> Order -> OrderDetails) with just 1 line of javascript and 1 line of C#.
