One of more bits of data you are passing are the wrong type. We don't know what types your data needs as we don't have the schema and we don't know what types you are giving as we don't know the inputs. You really need to learn to debug your own code so you don't have to start a thread for every little thing.

Off the bat you are passing the same value for everything (dataGridView1.Rows[i].Cells[0]) and it's highly unlikely that is what you actually meant to do, or that one value can possibly be text, a number, a date etc.

Don't convert the date to a string to pass it to SQL: if it's a DateTime value already, pass it as such. If not, use TryParse to convert it to a DateTime, and then pass that.

The trouble with string dates is that they aren't the same for all systems: the locale for an SQL Server instance can be different from that your code runs on, and what looks ok to you "23/12/10" looks bad to SQL because it's expecting MM/dd/yyyy and you passed it yy/MM/dd.
I also seriously doubt that the same row and column contains the right value for all of the columns you are trying to INSERT it into - you had noticed that you use the same cell for every parameter?
