datagridview without datatable

Question

Hello everybody I'm writing a windows app in C#. I'm using Visual Studio 2005. Is it possible to add data directly to a DataGridView without using a DataTable? With a DataGridView I can add a checkbox column at design time, but I can't add any data at run time. If I use a DataTable, I can add data at run time, but I can't seem to add a checkbox column. Thoughts anybody?
