Crystal Reports C＃

Question

我有一個基於我在下面使用SQL創建的數據庫的多c＃報表。我正在使用以下代碼嘗試設置數據源，並嘗試了許多不同的變體，但無法從我的數據庫中獲取信息，以便在報告中正確顯示。任何幫助是極大的讚賞。數據集正在填充。此外，單表報告正確地填充數據只有多項報表不起作用。

更新：報告現在使用report.Database.Tables["Invoices"].setDataSource(posDataSet.Tables["Invoices"]);顯示來自一個表的數據但是，在生成詳細信息行的表上使用相同的邏輯不會顯示任何數據。

    { 

     private PosDatabaseDataSet posDataSet; 
     public Reporter(PosDatabaseDataSet dataToReportOn) 
     { 
      InitializeComponent(); 
      posDataSet = dataToReportOn; 
      //InvoiceReport ir = new InvoiceReport(); 
      // this.reportViewer.LocalReport.ReportPath = ir.FileName; 

     } 

     private void Reporter_Load(object sender, EventArgs e) 
     { 
      ConnectionInfo myConnectionInfo = new ConnectionInfo(); 

      myConnectionInfo.ServerName = "";// "PosDatabaseDataSet"; 
      myConnectionInfo.DatabaseName = "";//"PosDatabase.mdf"; 
      myConnectionInfo.UserID = string.Empty; 
      myConnectionInfo.Password = string.Empty; 
      setDBLOGONforREPORT(myConnectionInfo); 
      //this.reportViewer.RefreshReport(); 
     } 

     private void setDBLOGONforREPORT(ConnectionInfo myconnectioninfo) 
     { 
      InvoiceReport report = new InvoiceReport(); 
      report.DataSourceConnections.Clear(); 

      // For each table set the source from your dataset 
      report.Database.Tables["Invoices"].SetDataSource(posDataSet.Tables["Invoices"]); 
      report.Database.Tables["InvoiceItems"].SetDataSource(posDataSet.Tables["InvoiceItems"]); 
      //report.Database.Tables["People"].SetDataSource(posDataSet.Tables["People"]); 
      report.Database.Tables["Preferences"].SetDataSource(posDataSet.Tables["Preferences"]); 
      //report.Database.Tables["Skus"].SetDataSource(posDataSet.Tables["Skus"]); 

      crystalReportViewer1.ReportSource = report; 
      crystalReportViewer1.RefreshReport(); 

     } 

     private void crystalReportViewer1_Load(object sender, EventArgs e) 
     { 
     } 
    } 
}

因爲你提供的報告數據，您應該不需要設置登錄代碼。請嘗試以下操作：

report.DataSourceConnections.Clear(); 

// For each table set the source from your dataset 
report.Database.Tables["TableName"].SetDataSource(posDataSet.Tables["TableName"]); 

crystalReportViewer1.ReportSource = report; 
crystalReportViewer1.RefreshReport();
