Nested TreeGrid ExtJs

I need to know if's possible to create a nested treegrid, where each level contains its own set of columns. Something like if I create a grid wich display this 2 classes:

public class Class
{
    public int Id { get; set; }
    public string ClassName { get; set; }
    public string Teacher { get; set; }
}

public class Students
{
    public int Id { get; set; }
    public string StudentName { get; set; }
    public DateTime Birthday { get; set; }
    public int IdClass { get; set; }
}

That when i display the grid there's a node of Class that show the class informations and when it expand, show the students informations

Yes, it is kind of possible (the columns will be the same for both types). You have two solutions:

  1. map all .net properties from both classes to a single Model in ExtJs and then render them in ExtJS (eventually showing data from both entities in the same columns: you decide how to combine data).

  2. Map all the relevant data from .net to a single field in ExtJS and render a single column.

Also you need a scheme to make all your nodes distinct (eg. the class with ID 1 in .net has the ID c1 in ExtJS and Student with ID1 in .net has the ID s1 in ExtJS). Also it should be clear that a single URl will be provide both the list of classes and the students for a class.
