ASP.NET（C＃）水晶报表导出失败，并显示“找不到方法。”

Question

as I said in title I have issue when I try to export crystal report to PDF, or anything like that, also when I try to print it I am having same issue, before anything I will post you screenshot to explain it more detailed:

I loaded report with my data from database and everything looks fine, reports is opened I can see my data, but when I try to export it to pdf or to print it I am seeing that Error, I've been trying for few hours to solve it, but unfortunately I couldn't make it working..

I have to mention, that I did next thing before this:

I set EnableDatabaseLogonPromt to False because before I did that, everytime I tried to do print or export I received this popup (so should I leave it setted to false to avoid this popup?)

HERE IS MY CODE:

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            var x = Server.MapPath("~");

            int playerId = Convert.ToInt32(Request.QueryString["playerID"]);
            PlayersDataSet players= new PlayersDataSet ();
            PlayersDataSet.PlayersTableDataTable playersDT = new PlayersDataSet.PlayersTableDataTable ();
            var player= Players.Data.Services.DAPlayers.GetByPlayerId(playerId);
            string clubname= Players.Data.Services.DAPlayers.GetClubNameByClubID(Convert.ToInt32(player.ClubID));
            playersDT.AddPlayersTableRow(player.FirstName, player.LastName, player.IDNUMBER, clubname, player.Photo, player.IDSerialNumber.ToString());

            players.Tables["PlayersTable"].Merge(playersDT);

            rpt_Players RPT = new rpt_Players ();
            RPT.SetDataSource(players);
            CrystalReportViewer1.ReportSource = RPT;

          }

Any kind of help would be great! Thank you guys, Cheers

回答我自己的问题很愚蠢，但是经过数小时的搜索和尝试许多不同的事情，我发现这是一个解决方案：删除此条件：if（！ispostback）{}，导出等都可以了。 ：:)
