        if (IsPostBack == true)
            return;
        DataTable dtTemp = new DataTable();
        dtTemp.Columns.Add("Student ID");

        CheckBox chk = (CheckBox)sender;
        TextBox1.Text = "";
        foreach (GridViewRow row in GridView1.Rows)
        {
            CheckBox chkBox = (CheckBox)row.FindControl("CheckBox1");
            if (chkBox != null && chkBox.Checked)
            {
                TextBox1.Text += " " + row.Cells[1].Text.ToString() + " " + row.Cells[2].Text.ToString() + " " + row.Cells[3].Text.ToString();
