如何从表关系制作水晶报表?

你好，我想从表关系中生成水晶报表.

我已经建立了一个非关联表，并在水晶报表中显示了记录成功.

但是，当我尝试建立关系表时，该记录未显示在Crystal报表中.对于非关系表，我尝试使用相同的方法，但是它是有效的.

这是我的代码:

Hello, I want to make a crystal report from table relation.

I''ve make for a non relation table, and the record success shown in the crystal report.

But, when I try for a relation table, the record is not displayed in the crystal report. I try with the same way for non-relation table, but it''s work.

Here is my code :

Option Explicit On
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Imports System.Data.SqlClient
Public Class PrintJadwalKuliah

    Dim xKoneksi As New SqlConnection
    Dim xAdapter As New SqlDataAdapter
    Dim obj_RepDoc As New ReportDocument
    Dim xDataset As New _FKIP_UNILAKDataSet()
    Private Sub PrintJadwalKuliah_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        xKoneksi.ConnectionString = "Data Source=RAGAZ-PC\SQLEXPRESS;Initial Catalog=FKIP-UNILAK;Integrated Security=True"
        xAdapter = New SqlDataAdapter("SELECT Hari.nama_hari , Jam.jam_kuliah , Jam.selesai , Ruang.Nama_Ruangan FROM slot INNER JOIN Hari ON slot.Id_hari = Hari.Id_hari INNER JOIN Jam ON slot.Id_Jam = Jam.Id_Jam INNER JOIN Ruang ON slot.Id_Ruangan = Ruang.Id_Ruangan", xKoneksi)
        xAdapter.Fill(xDataset, "Jadwal")
        obj_RepDoc = New CrystalReport_slotcoba
        obj_RepDoc.SetDataSource(xDataset)
        CrystalReportViewer1.ReportSource = obj_RepDoc
    End Sub
End Class

当我尝试向datagrid视图显示选择查询"时，显示的记录成功(我认为我的选择查询"很好)，那么对此有什么解决方案?

抱歉，我的英语不好，我是印尼人:)

When I try to show the "Select query" to datagrid view, the record succes shown ( I think my "select Query" is fine), So what is the solution for this one??

Sorry, my english bad, I''m an indonesian :)
