How to listen for a double click event in a cell of a datagrid?

Hello,

I'm using VS 2003. I have a datagrid that currently when the users double click on it, it only fires the double click event if the user clicks the far left column of the datagrid or the top row going across. If they double click just a cell in a particular row, it does nothing. How can I set a double click event to fire when a user clicks in just a cell of a given row

Thanks,
