        {
            CheckBox ChkBox = (CheckBox)e.Row.Cells[x].FindControl("yourCheckBox");
            TextBox TxtBox = (TextBox)e.Row.Cells[x].FindControl("yourTextBox");
            if (ChkBox.Checked == true)
            {
                TxtBox.Enabled = true;
            }
            else
            {
                TxtBox.Enabled = false;
            }
        }
