programatically resizing rows on a Windows Forms datagrid

I have a Windows Forms DataGrid that contains some cells with multiple lines of data. I would like the grid to automatically resize each row to fit all of the lines of each cell in that row. But, I can't figure out how to do it. It seems like it should be easy enough. The fact that I can double-click on the row separator in the row header to trigger the resize implies there is a method out there that will do this. But, my search for the method (or an event that triggers it) has been fruitless. I can't even figure out how to access the RowHeight property of an individual row of the DataGrid. Any thoughts on how I might be able to accomplish this? Thanks, Ken
