What you are asking is about developing a hierarchical grid in ASP.NET. Such a control is not directly available in ASP.NET and its a bit complicated process to develop a hierarchical grid. I have found a good example with sample code that could assist you.
Sample code uses DIV controls within the main grid view and the sub grids are created inside those DIV tags.

If you could buy third party controls Telerik would give you a very easy solution for this hierarchical grid. Telerik grid view supports up to three levels within a grid and tabbing controls within the grids. Telerik provides you very good samples, Tutorials and also forum support. So buying Telerik would be a good option. See the below link.
