我想導出2個不同的報表，當我點擊一個導出按鈕。問題是例程只會觸發一次，而我只能得到一份打印報告。難道我做錯了什麼？我認爲這與HTTPResponse有關，但我不確定。導出多個水晶報表ASP.NET
這裏是我的代碼：
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
，報告編號：
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
任何幫助將非常感激。
