这是我的CS下拉文件:

protected void BindDropDownList()     

    {

        DataTable dt = new DataTable();
        string connString = System.Configuration.ConfigurationManager.AppSettings["EyeProject"];
        SqlConnection conn = new SqlConnection(connString);


        try
        {
            conn.Open();
            string sqlStatement = "SELECT FirstName FROM tbl_UserDetails";
            SqlCommand sqlCmd = new SqlCommand(sqlStatement, conn);
            SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd);

            sqlDa.Fill(dt);
            if (dt.Rows.Count > 0)
            {
                DropDownList1.DataSource =dt;


                DropDownList1.DataTextField = "FirstName"; // the items to be displayed in the list items

                DropDownList1.DataBind();
            }
        }
        catch (System.Data.SqlClient.SqlException ex)
        {
            string msg = "No Data Found To display in the DropDown List"; …
