Patience. Your problem appears to me to be that you are trying to compare "DGv_Session[1, i]" which is a cell with the string "true".

It is telling you what the problem is. You cannot use "==" on a DataGridViewCell. Try using :

(DGv_Session[1,i]).ToString == "true" ? 1 : 0

Get rid of the Convert.ToString() for all of them.

how you're doing will get a DataGridViewCell which you should use to extract the correct value.
You could try accessing first row and then the column you need, for example:

well you access row DGv_Session.Rows[3]

I prefer to extract the contents of a datatable datasource or list as I show below:
List<YOUR_CLASS> _Detail;
_Detail = (List<YOUR_CLASS>)DGv_Session.DataSource;

then you just have to go with a list and go foreach concatenating values for your SQL query.

Greetings.

use this

VB

sql = "insert into Tb_Session_Structure ([Cmn_Minor_code],[Days],[Session1],[Session2],[Session3],[Session4])";
 sql = sql + " values ('" + cb_Course_Code.Text + "',
'" + DGv_Session.Rows[i].Cells[0].Value.ToString() + "',
" + Convert.ToString(DGv_Session[1, i].Checked == "true" ? 1 : 0) + ",
" + Convert.ToString(DGv_Session[2, i].Checked == "true" ? 1 : 0) + ",
" + Convert.ToString(DGv_Session[3, i].Checked == "true" ? 1:0) + ",
" + Convert.ToString(DGv_Session[4, i].Checked == "true" ? 1 : 0) + ")";

sorry.... use .Value

VB

sql = "insert into Tb_Session_Structure ([Cmn_Minor_code],[Days],[Session1],[Session2],[Session3],[Session4])";
 sql = sql + " values ('" + cb_Course_Code.Text + "',
'" + DGv_Session.Rows[i].Cells[0].Value.ToString() + "',
" + Convert.ToString(DGv_Session[1, i].Value == "true" ? 1 : 0) + ",
" + Convert.ToString(DGv_Session[2, i].Value == "true" ? 1 : 0) + ",
" + Convert.ToString(DGv_Session[3, i].Value == "true" ? 1:0) + ",
" + Convert.ToString(DGv_Session[4, i].Value == "true" ? 1 : 0) + ")";
