动态添加表格行

Question

I am trying to add values in table rows on button click. It's working on database but not working on web page. It override on last row on page.

How can I generate new row on every button click.

here is my button click code--

protected void Page_Load(object sender, EventArgs e)
{
    tblAdd.Visible = false;
    Label1.Visible = false;

    //Label2.Visible = false;


}

protected void btnSave_Click(object sender, EventArgs e)
{

    if (Page.IsValid)
    {
        CheckBox cb1 = new CheckBox();
        I = Hidden1.Value;
        I += 1;
        cb1.ID = "cb1" + I;

        TableRow Table1Row = new TableRow();
        Table1Row.ID = "Table1Row" + I;
        TableCell RCell1 = new TableCell();
        RCell1.Controls.Add(cb1);
        TableCell RCell2 = new TableCell();
        RCell2.Text = txtName.Text;

        tblLanguagesRow.Cells.Add(RCell1);
        tblLanguagesRow.Cells.Add(RCell2);
        tblLanguages.Rows.Add(tblLanguagesRow);
        Hidden1.Value = I;

        btnAdd.Visible = true;
        btnDelete.Visible = true;
        Label2.Visible = true;
        Label2.Text = "Successfully Added";
        add();
    }
    txtName.Text = "";
}

public int add()
{
    string strcon = ConfigurationManager.ConnectionStrings["Dbconnection"].ConnectionString;
    SqlConnection sqlConnection = new SqlConnection(strcon);

    SqlCommand command = new SqlCommand("hrm_AddLanguages", sqlConnection);
    command.CommandType = CommandType.StoredProcedure;
    command.Parameters.Add("@Name", SqlDbType.VarChar).Value = txtName.Text;
    command.Parameters.Add("@CreatedOn", SqlDbType.DateTime).Value = DateTime.Now;
    command.Parameters.Add("@UpdatedOn", SqlDbType.DateTime).Value = DateTime.Now;
    command.Parameters.Add("@CreatedBy", SqlDbType.BigInt).Value = 1;
    command.Parameters.Add("@UpdatedBy", SqlDbType.BigInt).Value = 1;
    command.Parameters.Add("@IsDeleted", SqlDbType.Bit).Value = 0;
    sqlConnection.Open();
    return command.ExecuteNonQuery();
}

If possible try to do this using Grid view. It is better to use grid view instead of table.
