我想导出2个不同的报表，当我点击一个导出按钮。问题是例程只会触发一次，而我只能得到一份打印报告。难道我做错了什么？我认为这与HTTPResponse有关，但我不确定。导出多个水晶报表ASP.NET
这里是我的代码：
Dim badgeSize As Integer = 0 'Drop Down selection
Dim badgeData As New DataSet 'Visitor Badge Data
Dim badgeEmployeeData As New DataSet 'Employee Badge Data
Dim badgeTotals As Integer = 0 'Totals for both
badgeSize = ddlBadgeSize.SelectedValue
' Get Visitor Data
badgeData = _DatabaseAccess.GetProjectReportData(sessionInfo.myEventID, sessionInfo.EventCreator)
' Get Employee Data
badgeEmployeeData = _DatabaseAccess.GetProjectReportEmployeeData(sessionInfo.myEventID, sessionInfo.EventCreator)
'Obtain Totals
badgeTotals = badgeData.Tables(0).Rows.Count + badgeEmployeeData.Tables(0).Rows.Count
If badgeTotals = 0 Then
ShowMessage("There are no badges to print.")
Exit Sub
End If
If badgeSize.Equals(0) Then 'Small
If badgeEmployeeData.Tables(0).Rows.Count > 0 Then
If badgeEmployeeData.Tables(0).Rows.Count >= 6 Then
PrintProjectBadges(badgeEmployeeData, "Employee", badgeSize)
Else
PrintStandardDymo(badgeEmployeeData, "Employee", 1)
End If
End If
If badgeData.Tables(0).Rows.Count > 0 Then
If badgeData.Tables(0).Rows.Count >= 6 Then
PrintProjectBadges(badgeData, "Visitor", badgeSize)
Else
PrintStandardDymo(badgeData, "Visitor", 1)
End If
End If
else
'do somethign else
endif
，报告编号：
Private Sub PrintProjectBadges(ByVal theData As DataSet, ByVal badgeType As String, ByVal badgeSize As Integer)
Dim ourReport As New ReportDocument
Dim crConnectionInfo As New ConnectionInfo(SetCrystalConnection)
If badgeSize = 0 Then
Try
If badgeType = "Visitor" Then
ourReport.Load(Server.MapPath("SmallProjectBadge.rpt"), OpenReportMethod.OpenReportByDefault) 'LIVE SERVER USE
Else
ourReport.Load(Server.MapPath("SmallProjectEmployeeBadge.rpt"), OpenReportMethod.OpenReportByDefault) 'LIVE SERVER USE
End If
Catch ex As Exception
Dim TraceList As New ArrayList
TraceList.Add("DBLog")
DatabaseAccess.WriteToErrorLog("Visitor Registration", "Printing Project Badges", ex.Message, TraceEventType.Information, 1, TraceList)
Exit Sub
End Try
ourReport.SetDataSource(theData.Tables("Project"))
Else
'Do somethign else...
End If
Response.Buffer = True
'Clear the response content and headers
Response.ClearContent()
Response.ClearHeaders()
SetLogon(ourReport, crConnectionInfo)
'Export the Report to Response stream in PDF format and file name Customers
ourReport.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, True, "Visitor_Badges")
Response.End()
'Response.Close()
End Sub
