Crystal Report Viewer Page Change Refresh Issue

Hello
I hope this is an easy question for someone out there.
I am using a crystal report viewer with the code contained in the page init event. The report has several pages and opens in a separate tab. There is also a on demand drilldown sub-report in the report.
When I want to move to the second page the viewer seems to process the code again (like its runs the page init event) which takes several seconds so will not be satisfactory for the users. I tried the concatenate the pages using the 'SeparatePages' property but then the user can't select a specific page.
Is there any way that the report can just open in the viewer and not have to reload everytime the user changes page?
Thanks in advance
Dave.

Hi Dave
In a web app, you could place the reports in session. See KBA: 1985571 - How to use sessions in web applications using the Crystal Reports viewer (the complete code)

Error when run crystal report viewer page

Hi I created form using vb 2008 contains crystalreportviewer and in load sub I wrote the following code to show the report:
Dim r_select As String
    Dim MyReport As New CrystalDecisions.CrystalReports.Engine.ReportDocument
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        r_select = "Select Innovative_Form.* from Innovative_Form"

SO WHAT IS THE PROBLEM?????

What version of CR are you using?
What CR updates are you using?
See sample apps here:
https://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsfor.NETSDK+Samples
in particular check out vbnet_win_pass_dataset_main_sub.zip
The [Crystal Reports for Visual Studio 2005 Walkthroughs|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/2081b4d9-6864-2b10-f49d-918baefc7a23] will also be good to look at.

Crystal Report Viewer 2008, postback causes a weird QueryString for dates

HI,
I'm having a weird problem that was masked with the error "".
What is happening to me is that i have an ASPX page where the QueryString passed in is used as parameters to the report (straightforward). When the page first loads, this is all fine the QuerySTring is properly parsed and the report is properly displayed. Now, the problem comes when i click on the PRINT Button it performs a postback, and during that postback the querystring is read so that it can rebuild the report on the postback. (In previous versions of crystal, this has always worked). The issue here is that the version 12 of the report viewer here now appears to also append some information to the query string that was not previously there (like this: ServletTask=Print&cmd=get_pg&page=1) So the problem here for me is this is what my original QueryString looks like:
tokenid=b2817081-6b52-43c7-8e2c-d6209af2ed98&Type=Appointment&Val=12%3b1%3b1%3b06%2f10%2f2000
THat query string is generated by the following code (pre-encoded)
"PrintPage.aspx?tokenid=" & Guid.NewGuid.ToString & "&Type=Appointment&Val=" & "12" & ";" & "1" & ";" & "1" & ";" & "1/1/2000" (NOTE the date here, i'll get to that in a second)
Then, what the problem is on the postback the Query String looks like this:
tokenid=2a4f42de-bd90-48b5-ac82-bd34b503afd3&Type=Appointment&Type=Appointment&Val=12%3b1%3b1%3b1%2f1%2fPrintPage.aspx%3ftokenid%3d2a4f42de-bd90-48b5-ac82-bd34b503afd3&Val=12%3b1%3b1%3b1%2f1%2f2000&ServletTask=Print&cmd=get_pg&page=1
As you can see here it's all messed up.
So, what i found here is that the underlying cause is that we are passing a "date" in the original QueryString and it seems on the postback the Crystal Reports Viewer is having some issue with that and basically messes up the query string...
I have Crystal Reports 2008/SP3 installed.
Any help would be greatly appreciated.
Thanks

Cleaning up these forums I came across this unanswered thread.
Very weird behavior that I have seen maybe 3 or 4 years ago - I think it was with opendocument.aspx...
In this case, we appear to be re-adding the querystring with the aspx name and question mark (u2026.parentagesu2026). Having two question marks (%3f) is essentially a malformed URL since this indicates where the querystring starts.
The duplicate querystring may have been a coding error(?) where it gets added again on a postback.
Were you able to resolve the issue?

One page turn out to be 4 pages in crystal report viewer, Bug?

we are using crystalReports xi release 2, visual studio 2005,IIS in windows 2003 and asp.net. We have one crystal report viewer in web page to dispaly one report, It has been running properly for several months in production server. Now we run into big issues. In report Views, one page report always turn into 4 small size pages. When we test it in visual studio 2005, it still works correctly without any problem. Even we unstalled IIS and reinstalled IIS, deployed web again, the problem is still there. It is very strange and frustrating to developer! Now we are afraid of handling crystal report, which seem arise many potential unexpected issue down the road. any clue?
the following is source got from IE browser, height for Viewer1 is only 367px,
normal value is 1039px,That is reason why page seems significantly shorter.How can we control the height? Even specifing size in css, it just be ignored.
LINK rel="stylesheet" type="text/css" aspnet_client/System_Web/2_0_50727/CrystalReportWebFormViewer3/css/default.css"><table id="CrystalReportViewer1" align="center" cellpadding="0" cellspacing="0" style="display:inline-block;border-style:Solid;height:367px;width:149px;">
style="width: 149px; height: 367px;position:relative"
Thanks in advanced.

Hi Rizwan,
You can't with the report itself because once the refresh is complete it requires a full refresh to update any page. And there is no option to for example refresh just the subreport.
RAS SDK has samples on how to add subreports, see the OverView tab for a link to the samples, but it still requires a refresh to be called.
One way may be to use Subreports on Demand, URL's to another report.... Each subreport would run individually without refreshing the main report. It would like a Table Of Contents report though.
So to be clear, adding pages is the same thing as adding more data. Problem is most of the data needs to be complete so that summaries and running totals etc. type of objects require the data to be complete to be able to render each page.
So why do you need to do this? Can you explain your workflow?

Crystal Report Viewer issues

Hi, I'm starting with CR viewer for CR 2008 in VS 2008.
I have 3 problems. Look like easy problems, buy during the morning, I didn't found any solution.
3 questions:
- I want CR viewer like "dock = fill". viewer size 100% height and 100% width. I set BestFitPage to true and it doesn't work. I set BestFitPage to false, height and width to 100% and it doesn't work.
- Size of the viewer is the same of the page container. If I change manually size of the page, CR viewer changes too. I don't know how can I do this.
- When height and/or width of the report is greater than page, vertical scroll bar and/ horizontal scroll bar shows.
Wher's the tip??
Thanks.

Hi,
Do you see this issue in the CR designer? If so, please post to the Report Design forum:
SAP Crystal Reports
Note that if the issue exists in the CR designer, the issue will exist at runtime also and needs to be resolved in the designer 1st.
Hope this will help!!

I am having this exact same issue, only on an ASP.NET page. I can print the report, but it does not display at all.

Crystal Report Viewer changes font

Hello,
I am having an issue with Crystal Report Viewer NOT displaying the correct fonts. Below are the steps to recreate the issue
1) Created a Blank Crystal Report using Crystal Report 2008.
2) Added a few fields in them and selected the following font for all the fields :Courier 10 cpi
3) Saved the report with data.
4) Viewed the report using Crystal Report Viewer 2008.
5) The fields displayed in this Report Viewer is NOT Courier 10 cpi.
Please tell if there is a fix for this problem. Please Note that using a different font is NOT an option since I will be printing the report to a Dot Matrix printer. Using a different font will slow down the printing speed.
Thanks
Krishnan

Hi Carl,
There is a font named Courier 10,12,15(VGA res) installed on the machine.
Also the Courier 10 cpi is selected on all fields on the report. But when I view the report from CR viewer, it changes to a different font.
Also the report does not print properly to the dot matrix printer. The speed of the report is very slow and the page alignment is off. The first 2 lines of the 2nd page are printed at the end of the first page. The first 4 lines of the 3rd page prints at the end of the 3rd page and it keeps getting worse by each page.

Page Not Found Error when clicking on Crystal Report Viewer print icon

Hi,
    I am working with ASP.NET 2.0 and crystla reportXI release2.
    I am getting "Page Can not be Found " error when clicking on Crystal Report Viewer print icon.
    Could you please tell me how to get rid of this error?
Regards,
Smitha

This sounds like a postback issue. Does your application handle postback by putting the report in session?
There is a [sample|http://devlibrary.businessobjects.com/BusinessObjectsXIR2SP2/en/en/CrystalReports_dotNET_SDK/crsdk_samples_aspx/data/crsdk_net_tutorials_115_en.zip] to look at on our website. It was created with Crystal Reports XI R2 and Visual Studio .NET but the code will be the same.
A short pseudocode would be something like this:
Dim rptDocument As ReportDocument
If Not Me.IsPostBack or Session("Report") = Nothing Then
rptDocument = New ReportDocument
rptDocument.Load(sGlobalPath & "\myreport.rpt";)

How to change default Export Format Type in Crystal Report Viewer

We are coding in VB.NET 2005 using the CR2008 SP1 .NET objects.
The Crystal Report Viewer, when displayed, defaults the export type as .rpt (Crystal Reports).
We distribute our .NET application to our customers. 99% of the time, this .rpt format is useless to our customers as they do not have crystal reports developer. They usually export to a .pdf or .xls format. Is there a way to default this export option to something other than .rpt?
Thank you.

Yes, that's as much as I figured.
With the Crystal for .NET methods, the CrystalDecisions.CrystalReports.Engine's reportdocument object has an ExportToDisk method. We wanted to use this (as we used something similar with the RDC) to prompt the user to export. However, the reportdocument's exporttodisk method does not have an argument that allows for Prompting the user (true/false) like the RDC's export did. You have to actually know ahead of time the type of export the user wants as well as the filename. Well, we do not, and therefore, want the user to be able to select the type of export they want as well as enter their own filename. We want the Crystal methods to prompt for this. Since we are unable to, we've had to resort to declaring a reportviewer object and setting the viewer's reportsource = to the reportdocument. We then use the ExportReport() method which defaults to .rpt (which none of our end users have Crystal Developer). This is why we want to know if there is a way to reset the default export method to something more common (such as .pdf or .xls). Is there a way to change the reportdocument's file type in order to default the export type? Just trying to come up with some sort of workaround...
Thanks

I couldn't use Crystal Report Viewer Control in my ASPX page.

Please I'm having a problem with crystal report viewer control which I couldn't resolve. I'm using VS 2008 and Framework 3.5.
I building an ASP web application and when I add a CrystalReportViewer to my ASPX page I'm getting the following
error.
"Error 20 Type 'CrystalDecisions.Web.CrystalReportViewer' is not defined."
I think maybe because I'm not having the right reference file. I'm using Crystal Reports 2008 and also I installed the following
Service Packs:
cr121_redist_install
CR2008-SP1
CR2008SP1-Fixes 1 and 2
cr121_clickonce
I check all the reference files in my project and they are as follow:
CrystalDecisions.CrystalReports.Engine (12.0.2000.0)
C:\Program Files\Business Objects\Common\4.0\managed\dotnet2\CrystalDecisions.CrystalReports.Engine.dll
CrystalDecisions.Enterprise.Framework (12.0.1100.0)

C:\Program Files\Business Objects\Common\4.0\managed\dotnet2\CrystalDecisions.Shared.dll (12.0.2000.0)
Please Why I'm getting this problem? How I can resolve it?
Thanks.

If you have a viewer on one of your forms, delete it off the form and re-add it, ensuring that the crystalreports.web assembly referenced in your project is version 12.

Crystal Reports Viewer Kerning issue

Hello, I am using the Crystal Reports Viewer and the .NET ReportDocument object to either display a Crystal Report or print it to PDF. I have one paragraph that is a disclaimer and appears in Times New Roman Italics. In this case, the word "of" appears with the letter o and the letter f almost overlapping. This only appears when using the viewer, if I use Crystal Reports to view or export the report, it works fine. If there is a way to upload images or supporting documents, I can provide an example.
Thanks, Steve

Hi Ludek,
- My default printer driver is Adobe PDF, installed with Adobe Acrobat 8 Professional. All reports will be printed to the Adobe Printer (not exported to PDF). I get better results this way.
- I tried without a printer selected as recommended with no effect.
- The problem is noticeable in both the viewer and the exported PDF.
- I have tried both a database field and a static text field. If you want I can create a text field in the report I supply to you that will be identical to the database field, so you can see that it occurs in both cases.
- Please note that this occurs in italicized text only. I'm using Times New Roman.
Let me know where I can provide you with the report file.
Thanks, Steve
P.S. I'm new to this forum so could you provide me with a link or an explanation on how to award points, what is appropriate, etc...

Problem in crystal report viewer control's toolbar "export"button using SSL

Hi,
I would like to ask. My project is using BO XI Release 2 and VS-Studio 2005. Initially my project doesn't use SSL... At that time when i view the report with crystal report viewer control and can export (using built-in toolbar "export button"). Now project is using SSL and canu2019t export the error is
u201CInternet Explorer cannot download file from server.
Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.u201D
Actually this error can solve "Cache-control" change to "no-cache". But I donu2019t know in crystal reportu2026
Anyone can help ???
Thanks

In Internet Explorer, go to Tools -> Internet Options -> Advanced and ensure "Do not save encrypted pages to disk" is unchecked.
Default is to have that option checked.
It was considered a IE security issue that IE saves all content to temp disk location unencrypted, even those pages served by HTTPS (for example, let's say you use HTTPS to download your bank info, and it's stored to temp disk for someone else to retrieve later). So more recent versions of IE implemented that option setting.
How that option setting works is strange - it downloads the file, saves to disk, then deletes the copy from the disk immediately, before passing it to the application responsible for the MIME type. So the application tries to open a directory path to a non-existing file.
Issue is specific to IE, and it's not something you can control via the SDK.
Sincerely,
Ted Ueda

Crystal Report Viewer fails for browser versions =10

If I change the user agent string in Firefox to that of Firefox 7.0.1 everything works as expected, this implies there is some logic in get_IsNetscape6Up() which is failing because the major browser version as reported by the user agent string is two digits instead of one.
We encountered a similar issue for our legacy pages containing Infragistics 2007 controls but were able to fix that by overriding the System.Web.Configuration.HttpCapabilitiesBase.BrowserCapabilitiesProvider and faking the browser version to 9.80. Crystal Report Viewer is apparently not using .Net's built in HttpBrowserCapabilities object, is there anything else I can adjust to stop the viewer failing?

hello Robert
Today must be my day. I already got a reply from PM (normally it takes a "bit" longer...). Anyhow, here is what he said:
With Firefoxu2019s release cycles, I donu2019t think weu2019ll be able to officially support the latest versions
of Firefox at every service release. We do our best to test the released versions of Firefox
that align with our releases. I donu2019t know the details but Iu2019ve heard there is a plan in place where
the support team(s) (?) will test the most recent releases of Firefox with whatu2019s currently
shipping by SAP and log bugs as necessary.
(umm, this is my - Ludek note here ) -> news to me re. support doing QA... find out something new every day. Anyhow, continuation of the message from PM:
The current plan for CR for VS2010, the SP3 release (expected in April) will support up to
Firefox 9. If there are reproducible bugs in Firefox 10 (or higher), then please enter a bug
and escalate and it will be investigated for the next available release.
I'll revisit this once SP3 is out there and do an escalation for Firefox 10 - ok?

Crystal Reports Viewer 2008 and parameter fields

Hello,
I saw this product on the main Crystal Reports site this afternoon and decided to download it to try it out. I have a number of users who would benefit from being able to preview their report results prior to actually running the report. This seems like the perfect product. I have a large number of Crystal Reports which were created in Crystal version XI. I also downloaded the free 30 day version of Crystal Reports 2008 yesterday to see what new features are there.
While testing Crystal Reports Viewer, I tried to run one of my reports which needs a parameter to run properly (account number). This type of parameter is needed for probably 98% of this business' reports.
The problem: Crystal Reports Viewer does not prompt me to input the parameter. In my actual Crystal Report, I had the box "Save Data with Report' left unchecked, as the account number frequently changes. However, if that box is left unchecked, Crystal Reports Viewer will give me the error message "No Saved Data. This report file does not contain saved data and cannot be viewed. To get data into the report, please open and re-save it in the Crystal Reports designer application with the "Save Data with Report" option selected."
Thinking that possibly it was the version of Crystal Reports in which the report was created (XI), I downloaded the free trial of Crystal 2008 and created a very simple test report with one parameter for account number where the account number is retrieved from our database. And I am having the same trouble.
The "Help" section of Crystal Reports Viewer tells me that I can select my parameters in the parameter panel. I do not see anything in my parameter panel other than the words "Current Data Set Last refreshed: 04/12/10 2:58 PM". The help tells me that I can "select the parameter directly in this panel by entering a new value", but there is no option to do so.
Any help would be appreciated.
thanks,
Noel

What I've learned is that I was originally using Crystal Viewer XI and upon opening it I received a message indicating there was an update.
I ran the update which put me on Crystal Viewer 2008.
Since then I have not been able to refresh my screen to bring up the parameters.
See the attached forum for another post concerning this same issue.
