如何在column.expression中插入文本框或标签的值？或者甚至可能吗？

我想要的是在我的代码中将每个列行的值与文本框或标签的值分开，就像这样一个TotalColumn.Expression = "Tscore / "; //然后分配标签的值

我的代码

`conn.Open();
                using (OleDbCommand cmd = new OleDbCommand(query, conn))
                {
                    cmd.Parameters.AddWithValue("?", int.Parse(textBox1.Text.ToString()));
                    cmd.Parameters.AddWithValue("?", comboBox1.SelectedItem.ToString());
                    try
                    {
                        sda = new OleDbDataAdapter();
                        sda.SelectCommand = cmd;
                        datset = new DataTable();
                        dataGridView1.DataSource = datset; 

                        //DataTable myDataTable = new DataTable();





                    sda.Fill(datset);
                    bsource = new BindingSource();
                   // DataColumn column1 = datset.Columns[3];
                   // DataColumn column1 = datset.Columns[4];
                    DataColumn TotalColumn = datset.Columns[6];

                    //Set the Expression here
                    int a = int.Parse(label2.Text);
                    TotalColumn.Expression = "Tscore / "; //here i want to insert it here




                    dataGridView1.AllowUserToDeleteRows = false;
                    dataGridView1.AllowUserToAddRows = false;
                    dataGridView1.AllowUserToResizeColumns = false;
                    dataGridView1.AllowUserToResizeRows = false;

                    dataGridView1.MultiSelect = false;
                    //dataGridView1.ColumnHeadersVisible = false;
                    dataGridView1.RowHeadersVisible = false;
                    dataGridView1.ScrollBars = ScrollBars.Vertical;




                    dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;

                    dataGridView1.DefaultCellStyle.SelectionBackColor = Color.Red;
                    dataGridView1.DefaultCellStyle.SelectionForeColor = Color.Yellow;

                    //dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
                    dataGridView1.Columns[1].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft;
                    //bsource.DataSource = datset;
                    //dataGridView1.DataSource = bsource;
                    //DataGridViewColumn column = grid.Columns[0];
                    //column.Visible = false;
                    try
                    {
                        dataGridView1.CurrentCell = dataGridView1[1, 0];
                    }
                    catch { }

                    //DataGridViewColumn column1 = grid.Columns[1];
                    //column1.Width = 265;
                    //column1.SortMode = DataGridViewColumnSortMode.Programmatic;
                    sda.Update(datset);

                }
                catch (Exception ex)
                {
                    MessageBox.Show("" + ex);
                }
            }
