I have some questions about FlyGrid. I need to create a Grid that have some requirements.
First of all, I need to add a button (or a control) into a cell but I cannot use ButtonColumn class because much of the times I don't use a button. Also, I would need a cell to span multiple columns. What I need is something like this:

----------------------------------
| ID   |  Name    | Telephone |
----------------------------------
| 001 | Serras    | 87394949  |
----------------------------------
| More info.        | (BUTTON) |
----------------------------------

I would also need nested grids with different columns on each. Is it possible in FlyGrid? If not, is there any way to collapse a nested grid before showing another one, and then adding the new columns? Wil it cause any exception?

However, what I need more is span columns and adding controls in some cells. And maybe controls in cells that span

Thanks in advance
