Hi,
I have done the similar thing in windows app Gridview's click event,i want to access grid's selected row's 9th cell value which is a check box,try this and make your logic

string valuechk = dataGridView1.CurrentRow.Cells[9].Value.ToString ();
// int value = int.Parse(valuechk);
 bool chkvalue = Convert.ToBoolean(valuechk);
 
 //if (dataGridView1.CurrentRow.Cells[8].Value == "0")
 if(chkvalue ==false)
      assignchk.Checked = false;//assignchk is a check box on form
  else
      assignchk.Checked = true;
