我想在datagrid中查看它，每次用户单击按钮时都会添加输入。我该如何做到这一点。现在它可以保存到数据库…但是我想让它在界面中以数据网格的顺序查看每次用户点击添加数据时，它都会保存到数据库中并在前端以数据网格格式显示。TQ

  protected void Button2_Click(object sender, EventArgs e)
    {
        if (Session["Time"].ToString() == ViewState["Time"].ToString())
        {
            SqlConnection connection = new SqlConnection("Data Source=RGUNASEL-   DESK''SQLEXPRESS;Initial Catalog=eLogbook;User ID=sa;Password=1234");
            connection.Open();
            SqlCommand cmd = new SqlCommand("eform2", connection);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add(new SqlParameter("@lot_num", SqlDbType.VarChar, 50)).Value = TextBox8.Text;
            cmd.Parameters.Add(new SqlParameter("@location", SqlDbType.VarChar, 50)).Value = TextBox9.Text;
            cmd.Parameters.Add(new SqlParameter("@total_in", SqlDbType.VarChar)).Value = TextBox10.Text;
            cmd.Parameters.Add(new SqlParameter("@first_test", SqlDbType.VarChar, 50)).Value = TextBox11.Text;
            cmd.Parameters.Add(new SqlParameter("@second_test", SqlDbType.VarChar)).Value = TextBox12.Text;
            cmd.Parameters.Add(new SqlParameter("@third_test", SqlDbType.VarChar, 50)).Value = TextBox13.Text;
            cmd.Parameters.Add(new SqlParameter("@total_out", SqlDbType.VarChar, 50)).Value = TextBox14.Text;
            cmd.Parameters.Add(new SqlParameter("@lot_status", SqlDbType.VarChar, 50)).Value = TextBox17.Text;
            cmd.Parameters.Add(new SqlParameter("@remark", SqlDbType.VarChar, 50)).Value = TextBox16.Text;
            cmd.ExecuteNonQuery();
            Response.Write("Submitted!");
            TextBox8.Text = null;
            TextBox9.Text = null;
            TextBox10.Text = null;
            TextBox11.Text = null;
            TextBox12.Text = null;
            TextBox13.Text = null;
            TextBox14.Text = null;
            TextBox17.Text = null;
            TextBox16.Text = null;

            Session["Time"] = DateTime.Now.ToString();
        }
        else
        {
            // Code for page refresh....
            TextBox8.Text = null;
            TextBox9.Text = null;
            TextBox10.Text = null;
            TextBox11.Text = null;
            TextBox12.Text = null;
            TextBox13.Text = null;
            TextBox14.Text = null;
            TextBox17.Text = null;
            TextBox16.Text = null;
            Response.Write("Page Refreshed!");
        }
    }

无需检查时间，只需在每次添加数据/行后重新绑定gridview。

//Code to bind gridview
Dataset dst=yourFunctionToGetRequiredTableRows();
yourGridView.DataSource=dst;
yourGridView.Databind();
ie 

protected void Button2_Click(object sender, EventArgs e)
    {
        SqlConnection connection = new SqlConnection("Data Source=RGUNASEL-   DESK''SQLEXPRESS;Initial Catalog=eLogbook;User ID=sa;Password=1234");
        connection.Open();
        SqlCommand cmd = new SqlCommand("eform2", connection);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.Add(new SqlParameter("@lot_num", SqlDbType.VarChar, 50)).Value = TextBox8.Text;
        cmd.Parameters.Add(new SqlParameter("@location", SqlDbType.VarChar, 50)).Value = TextBox9.Text;
        cmd.Parameters.Add(new SqlParameter("@total_in", SqlDbType.VarChar)).Value = TextBox10.Text;
        cmd.Parameters.Add(new SqlParameter("@first_test", SqlDbType.VarChar, 50)).Value = TextBox11.Text;
        cmd.Parameters.Add(new SqlParameter("@second_test", SqlDbType.VarChar)).Value = TextBox12.Text;
        cmd.Parameters.Add(new SqlParameter("@third_test", SqlDbType.VarChar, 50)).Value = TextBox13.Text;
        cmd.Parameters.Add(new SqlParameter("@total_out", SqlDbType.VarChar, 50)).Value = TextBox14.Text;
        cmd.Parameters.Add(new SqlParameter("@lot_status", SqlDbType.VarChar, 50)).Value = TextBox17.Text;
        cmd.Parameters.Add(new SqlParameter("@remark", SqlDbType.VarChar, 50)).Value = TextBox16.Text;
        cmd.ExecuteNonQuery();
        //Response.Write("Submitted!");
        //Code to bind gridview
        Dataset dst=yourFunctionToGetRequiredTableRows();
        yourGridView.DataSource=dst;
        yourGridView.Databind();
    }
编辑:

public Dataset yourFunctionToGetRequiredTableRows()
{
 Dataset dst=new Dataset();
 //"your SQL SELECT statement here".
 return dst;
}
