No OLE,No flex grid, best simple grid?

As far as I understand there is no OLE controls in .NET. Previously I was inserting an Excel spreadsheet into a form, that is a nogo now. I want to display some data and allow some data to be entered in a 2 dimensional form. What is the best way to display a 2D grid?

Datagrid seemed to need to be connected to a Database.

Is there another grid that I am just missing?

You can Connect the DataGrid to Single dimension arrays as well as anything that implements IList and IListSource. Also, remember DataSets don't have to be connected to databases. Actually, by their nature they are disconnected. You can create your own in code to hold any data you want to display in the DataGrid.
