如何根据数据库中的值显示Gridview

Question

我想根据TypeOfServices检查ClientId中的服务，并检查所有服务。

数据库列为TaxId, ClientId, ClientName,TypeOfservice

gridview应按字母顺序显示客户名称，并且显示的服务应显示“是”否则为“否”

我使用了这个C＃代码，但它不能正常工作......

     protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lblclientname = (Label)e.Row.FindControl("lblclientname");

        Label lblincometax = (Label)e.Row.FindControl("lblincometax");
        Label lblprofessionaltax = (Label)e.Row.FindControl("lblprofessionaltax");
        Label lblservicetax = (Label)e.Row.FindControl("lblservicetax");
        Label lbltds = (Label)e.Row.FindControl("lbltds");
        Label lblvat = (Label)e.Row.FindControl("lblvat");
        Label lblcompanylaw = (Label)e.Row.FindControl("lblcompanylaw");

        string m = "SELECT * FROM tblTaxMaster";
        ds = gs.getdata(m);
        for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
        {
            if (ds.Tables[0].Rows.Count > 0)
            {
                string ClientId = ds.Tables[0].Rows[0]["ClientId"].ToString();
                string TaxId = ds.Tables[0].Rows[0]["TaxId"].ToString();

                string ser = "select TypeOfService from tblTaxMaster where ClientId= '" + ClientId.ToString() + "' and TaxId = '" + TaxId.ToString() + "' ";
                ds = gs.getdata(ser);

                if (ser == "INCOME TAX")
                {
                    lblincometax.Text = "YES";
                }
                else
                {
                    lblincometax.Text = "NO";
                }

                if (ser == "TDS")
                {
                    lbltds.Text = "YES";
                }
                else
                {
                    lbltds.Text = "NO";
                }
                if (ser == "PROFESSIONAL TAX")
                {
                    lblprofessionaltax.Text = "YES";
                }
                else
                {
                    lblprofessionaltax.Text = "NO";
                }
                if (ser == "SERVICE TAX")
                {
                    lblservicetax.Text = "YES";
                }
                else
                {
                    lblservicetax.Text = "NO";
                }
                if (ser == "VAT")
                {
                    lblvat.Text = "YES";
                }
                else
                {
                    lblvat.Text = "NO";
                }
                if (ser == "COMPANY LAW")
                {
                    lblcompanylaw.Text = "YES";
                }
                else
                {
                    lblcompanylaw.Text = "NO";
                }
            }
        }
    }
}

这是ASP.Net代码
