   [.net] Making a spreadsheet. How?
  I am trying to learn C# and shall do a basic Excel-like program where I can copy cells etc. Is there any free data grid classes that should suit this purpose? Any hints would be greatly appreciated!   
  If you want an already-made custom control, I'd recommend searching on CodeProject; there's lots of good stuff on there. If you want to do it using the basic .Net Framework controls you should probably check out the DataGrid.   ;  Check this out.  The woman that runs this page is totally in love with datagrids, so she has compiled a list of articles that should certainly be able to help you out while you're learning more about the DataGrid Control.
