datagrid cell color changed based on dateTime

I have a bound datagrid on an asp.net page. One column is filled with a DateDue, datetime. I am trying to check and if the date is less than a week out, I need to make the cell or text Red. This is what I've attempted and, of course, it doesn't work: private void dgProjects_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) { if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { DataRowView drv = (DataRowView)e.Item.DataItem; if(drv.Row.ItemArray[6] <= DateTime.Now )//and somehow add 7 days to this date) { e.Item.Cells[3].BackColor = Color.Red; } } } Thanks - I appreciate any help!!
