Error Rendering A SSRS Report Using ReportExecutionService Class

Jan 8, 2008



Hi all,

I am trying to render a report using the ReportExecutionService class render method. The report has a parameter ( Combo Box) which gets populated when the report is opened in report server. there are other parameters also. I am passing all the parameters in an array ParameterValue[] .

But the execution throws an error . I tried to catch the error using SoapException and the Error Code was "

rsReportParameterValueNotSet" for that parameter.

What i get is that i will have to paa all the parameters after opening the report so that the parameter (Combo box) get populated with the values and after that if I pass the parameters it should work.

For Example on the report server , when i open the link to the report that time it populates the data for parameter. Then i get the list of values gor the parameter.I am not able to find a way how to get this done through code.

I am not able to find any help regarding this. Please help at earliest.

Regards..
Girija Shankar

SSRS Report Rendering Different In VS2005 And In Report Viewer Via URL Access

Apr 17, 2008

Hello,
I'm using Reporting Services to render a text (stored in sql as varchar(max)). The text is all plain text, with some lines having trailing spaces.

Source text file i've imported to SQL via SSIS:
CLIENT: 10055
STATEMENT 2007
DATE:1002993
THIS IS THE OTHER STATEMENT
COLUMN1 COLUMN2 COLUMN 3
TRY THIS


*Note the trailing spaces on the line before 'STATEMENT 2007'.

I've designed a report using the Report Project in VS2005 to retrieve this text via a stored procedure. When I test the report using the 'Preview' tab in the IDE, it looks good
CLIENT: 10055
STATEMENT 2007
DATE:1002993
THIS IS THE OTHER STATEMENT
COLUMN1 COLUMN2 COLUMN 3
TRY THIS



But when I deploy the report and run it using URL Access:

CLIENT: 10055
STATEMENT 2007
DATE:1002993

THIS IS THE OTHER STATEMENT

COLUMN1 COLUMN2 COLUMN 3
TRY THIS

On all lines with trailing spaces, they (the trailing spaces) have been removed. This is affecting my formatting of some reports and statements. We really want to use the report viewer as it has built in paging, print and export capabilities.

Why does it look okay in VS2005 but different in Report Viewer via URL Access and Report Manager?

Note: When I export as PDF, it looks okay.

The stored procedure I use to return the data is a CLR Hosted assembly as below:



Code Snippet
Partial Public Class StoredProcedures
<Microsoft.SqlServer.Server.SqlProcedure()> _

Public Shared Sub GetPagedDocument(ByVal inText As SqlString)
Dim dr As SqlDataReader
Dim row As New SqlDataRecord(New SqlMetaData("RowText", SqlDbType.Text))
Dim cmd As New SqlCommand("select cast(doc as varchar(max)) as 'DOCTEXT' from testdoc WHERE id='" + inText + "'")
Dim cn As New SqlConnection("context connection=true")
cn.Open()
cmd.Connection = cn
SqlContext.Pipe.SendResultsStart(row) 'initialise the resultset to be returned
dr = cmd.ExecuteReader
'If no records in result set, return.
If Not dr.HasRows Then

row.SetString(0, "There is no document to display or you do not have permission to view the document.")
SqlContext.Pipe.SendResultsRow(row)
SqlContext.Pipe.SendResultsEnd()
' SqlContext.Pipe.Send("There is no document to display.")
Return
End If
'Read rows in the result set
dr.Read()

'Get the entire text
Dim docText As String = dr.Item("DOCTEXT")
'debug
row.SetString(0, docText)
SqlContext.Pipe.SendResultsRow(row)
SqlContext.Pipe.SendResultsEnd()
Return
'end debug

End Sub
End Class




Any help will be appreciated.

T-SQL (SS2K8) :: SSRS Report Rendering When Exported To MS Word

How To Figure Out If The Dataset Returned Any Data Or Not While Rendering The Report Through The SSRS Web Service

Jan 12, 2007

In one of my projects, i have been using the SSRS web service to render a report as pdf and then manually emailing it out.

I need to know whether the data set for the report returned any data or not (so that i can avoid emailing the report with a blank report body).

Ofcource this can be done by executing the same query (same as the query for the report) from C# code and checking the count of the resultset, before calling the SSRS Render method. But it might not be an efficient method.

Was wondering the the SSRS Web Service provides an property or method that can let me figure out whether the resultset was empty or not (after the report execution).

Thanks.

Reporting Services :: SSRS 2005 Custom Report Rendering Format Not Working?

Jun 3, 2015

I'm trying to add a custom report format to ssrs 2005 as per this [URL] I've added the code snippets in the example to three different ssrs 2005 server RSReportServer.config files but it does not work i.e do not show up in the export drop down when rendering report.

I've tried starting and stopping reporting services and it still does not works.

I've also modified the existing csv extension  with different options to see if it works but to no avail.However it works with SSRS2008 R2 . In fact it works right after I saved the config file, no restart needed.For SSRS2005 the file is in C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesReportServer. I checked the registry setting  just to make sure I'm looking at the correct installation 'HKEY_LOCAL_MACHINE', 'SOFTWAREMicrosoftMicrosoft SQL Server90ToolsClientSetup', 'SQLPath' The three ssrs2005 instances are in three different physical servers and the problem is with all of them so it is not an isolated incident. I've dbowner rights to all three servers. The server versions are 9.0.4060, 9.0.4035 and 9.0.4053

SoapException While Rendering Report Through WebService - Error During Processing Of ‘ReportParameterTime’ Report Parameter

May 5, 2008

I am extracting RS reports through a WebService:
report = execService.Render("EXCEL", null, out extension, out mimeType, out encoding, out warnings, out streamIds);

Some works fine but some are generating the following SoapException:

Error during processing of €˜ReportParameterTime€™ report parameter. ---> Error during processing of €˜ReportParameterTime€™ report parameter. ---> Error during processing of €˜ReportParameterTime€™ report parameter.
I set required parameters to their default values. In this specific report I have two required parameters:
1: ReportParameterTime, String
2: ReportParameter1, String

I set them to their default values (ReportParameterTime to "[Czas].[Kalendarzowy].[Rok].&[2007]" - means
Time Calendar Year 2007) but I am getting the exception above. I set parameters using this code:

execService.SetExecutionParameters(parameterValues.ToArray(), CultureInfo.CurrentCulture.Name);

Where parameterValues is a List<ReportExecution2005.ParameterValue>.

When I am using Microsoft.Reporting.WinForms.ReportViewer the report is generated without
any problems. I can see one parameter to choose: "Kalendarzowy" (means adj. Calendar) and can
select years, the default value is "2007".

What am I doing wrong and how can I fix this error ? Does anybody know ?

Regards,
Daniel

I have developed a report in SSRS 2005. When I try to export the output to Excel, it shows an error saying:



Error occurred during local report processing.

Error occurred during rendering of the report. Stack Empty.



Do anyone have any idea what this means and how to fix it?



I can render the report in other formats (Adobe, csv etc) without any problem. My other reports, under same project and using same dataset, are working fine.

Either Rendering Tiff Images In SRS Report Viewer Or Converting Tiff To Jpg Or Gif And Then Rendering

Jun 19, 2007

First of all, this is not in reference to using SRS (SQL Reporting Services) to render a report and then use one of the extensions to render the complete report as a pdf, tiff, excel etc. We have an opportunity to render a list of claims and then embed the supporting docs for each of the claims within the report. We don't have an issue referencing jpg and gif images via URLs and then rendering them within the report after the grid information. We do have an issue rendering tiff images within the report.



You can insert an image object into SRS at design time and have it render and you can convert a complete report to a tiff image but I cannot find a way to be able to render a tiff image when running the report. All you get is the red "x".



My question is has anyone encountered the same issue and, if so, what did you do to resolve the issue?



Thank you,

Error Programaticaly Rendering A Report Using Reporting Services Web Services

Dec 19, 2006

I'm using Reporting Services 2005 SP1 and wrote some code to render reports server-side.
My sample report has few parameters that must be passed so I pass these parameters with code.

<My code>
ReportServiceExecution.ReportExecutionService rs = new ReportServiceExecution.ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
string extension, mimeType, encoding;
ReportServiceExecution.Warning[] warnings;
string[] streamID;

ParameterValue[] parameters = new ParameterValue[2];

parameters[0] = new ParameterValue();
parameters[0].Name = "pID";
parameters[0].Value = "6548747";

parameters[1] = new ParameterValue();

parameters[1].Name = "pClass";

parameters[1].Value = "8";


ExecutionHeader header = new ExecutionHeader();
ExecutionInfo executionInfo = rs.LoadReport(reportPayslip.Name, null);
executionInfo = rs.SetExecutionParameters(parameters, "en-us");
rs.ExecutionHeaderValue = header;
rs.ExecutionHeaderValue.ExecutionID = executionInfo.ExecutionID;

byte[] report = rs.Render("PDF", "<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>", out extension, out mimeType, out encoding, out warnings, out streamID);
</My code>

Actually, I have several more parameters but I've checked the collection and all the parameters I want are there and have values. Their names match those found in executionInfo.Parameters. But when I run my code I get the following error on Render():

<Error>
"This report requires a default or user-defined value for the report parameter 'pClass'. To run or subscribe to this report, you must provide a parameter value. ---> This report requires a default or user-defined value for the report parameter 'pClass'. To run or subscribe to this report, you must provide a parameter value. ---> This report requires a default or user-defined value for the report parameter 'pClass'. To run or subscribe to this report, you must provide a parameter value."
</Error>

I've double-checked and my parameter array does have the problematic parameter, I passed it a value but when I check executionInfo.Parameters I see that it's the only parameter that hasn't been give a default value after calling SetExecutionParameters(). So my parameters do seem to be passed but one seems to refuse getting a value. If I comment out the SetExecutionParameters() line I get, as expected a similar error but on another parameter (first one in the executionInfo.Parameters collection). So I'm left to beleive that the SetExecutionParameters() has some kind of bug as it works for all but one parameter. I've checked casing, spelling, tried passing phony parameters and from what I've seen I should be getting an error when I pass the parameters if I got something wrong.

Any help would be much appreciated.

Reporting Services :: SSRS Rendering In CSV

Jun 11, 2015

My system environment: win2008 R2 SP1 64bit + SQL 2005 SP4 32bit

I amended the configuration file of rsreportserver.config with the below:

<Extension Name="CSV" Type="Microsoft.ReportingServices.Rendering.CsvRenderer.CsvReport,Microsoft.ReportingServices.CsvRendering" >
  <Configuration>
  <DeviceInfo>
   <Encoding>UTF-8</Encoding>
  </DeviceInfo>
  </Configuration>
   </Extension>

If I run the report and then click export by selecting the csv format, it looks ok with the encoding of UTF-8.

However, the same report , when I created a subscription and saved it in the hard driver. Its encoding became USC-2 Little Endian.

Reporting Services :: Image In SSRS In PNG Format - PDF Rendering

Nov 4, 2015

I have a image in SSRS which is of PNG in format. when I preview the image it is coming as expected but if I  export that to PDF the image is having the black color back ground. One more point to be noted here is my actual image file is having a small shading in it which is not visible properly, but the same back ground is coming with full black color line in the PDF form.

Another issue is : I have 3 sub reports in my SSRS report. In the preview I can see the data is coming in order of sub reports but if I export it to PDF the second sub-report data is coming at the end of the report and first and 3rd sub reports are fine. But If I have only one record for 2nd sub-report the order is same in both the Preview page as well as in the PDF format.

Reporting Services :: SSRS 2014 Default Rendering Extension

Sep 25, 2015

I installed SSRS 2014 Reporting Services on a 2008R2 Enterprise server. When I try to subscribe to a report (also SQL 2014), the default rendering is MHTML. I want to change this default to EXCEL.

I updated the rsreportserver.config file and restarted SQL Server Reporting Service.  Now, the default rendering for a subscription is 'XML file with report data' which is the first <Render> data element.  If I change

<DefaultRenderingExtension>EXCEL</DefaultRenderingExtension> back to <DefaultRenderingExtension>MHTML</DefaultRenderingExtension>

And restart SSRS Service, the default subscription rendering is MHTML.

 <Extension Name="Report Server Email" Type="Microsoft.ReportingServices.EmailDeliveryProvider.EmailDeliveryProviderControl,ReportingServicesEmailDeliveryProvider">
    <DefaultDeliveryExtension>True</DefaultDeliveryExtension>

Reporting Services :: SSRS Print Layout Support RTL Rendering

Apr 28, 2015

Is there a support of printing report with matrix that is set to RTL (LayoutDirection) which displays in ReportViewr control with property RightToLeft set to RightToLeft.Yes in DisplayMode = PrintLayout.

The report looks fine in the report viewr in DisplayMode = Normal, but when goes to PrintLayout, it seems that the left data on page is rendered first.

Example: This is the display of the report viewer, I would like to print the columns by the same order it displays here:

And this is the result when clicking Print Preview: the first page displays the data of the last columns and if i go to the last page (page 9) i will see the data of the first column as displays in the previous gif, I don't have a clue why?

Is there a property that can be set to force the print layout to render RTL. Anyway, it seem to me as a bug since the Report Viewer displays the data correctly and renders the data RTL as expected.

Full Feature Demo For SSRS Web Service Rendering (with Interactive Sort)?

Dec 16, 2006

Is there any example I can find a full feature demo of SSRS Web Service Rendering with Interactive Sort and other features enabled?

For MS: Indeed I think ReportViewer Control should be an open source component as we as developer needs the flexibility to customize the report viewer interface as well as can learn directly from the control source so to understand how can we integrate better with SSRS.

Reporting Services :: SSRS 2012 - CSV Rendering / Turn Off Double Quote Qualifier

Sep 29, 2015

I have scoured the Microsoft forums and the internet to find out how I can generate the output of a CSV report that has double quotes around each value and is comma separated as follows:

"Abcd","123456","Efghi","789012","JKLMN"

If I try to concatenate double quotes around the values in the stored procedure or in the RDL, two double quotes appear around each value as follows. 

""Abcd"",""123456"",""Efghi"",""789012"",""JKLMN""

I understand that this is because the default qualifier is double quote.  What I see is that every time a double quote appears in a value (along with commas and line breaks), the qualifier will activate.  Is there any way to turn this off for double quotes? 

If I try to enter:  <Qualifier>false</Qualifier>, the word "false" appears as the qualifier instead.

The only way I have found that produces a result similar to what I need ("Abcd","123456","Efghi","789012","JKLMN") is if I add a line break - chr(10) in the RDL in each field. However, this won't work for me because I can't have line breaks in each field in the output. 

Note that in SSRS 2005, I was able to produce the report output as I state above by setting the field delimiter and qualifier as follows:

<FieldDelimiter>@?!?@</FieldDelimiter>
<Qualifier>?#^?</Qualifier>

This essentially turned the field delimiter and qualifier off, as the values entered would never appear in the data.  I then could add double quotes and commas in the RDL.  This used to work in the old version but does not anymore.

Reporting Services :: SSRS Chart Series Conditional Color Formatting Not Rendering In Browser

Aug 6, 2015

I have a chart with series that needs conditional colour for three conditions. One condition must be transparent. I have tried the various IFF or SWITCH expressions below and some work fine in SSDT but when I deploy them to the browser the formatting is lost. This simple IFF expression works. The series is transparent as required both in SSDT (Visual Studio BIDS) and IE11 and Firefox browsers but I need two other conditions. 

=IIF(Fields!ExhibitionID.Value = -1, "#00ffffff", "Red")

Both of the expressions below work in SSDT (Visual Studio BIDS) as expected but when deployed to the browser none of this formatting is rendered and all series are in blues even the ‘transparent’ series. No red at all.

=IIF(Fields!ExhibitionID.Value = -1,"#00ffffff", IIF(Fields!ExhDepartment.Value = 27,"Orange","Red"))
=Switch(Fields!ExhibitionID.Value
= -1,"#00ffffff",Fields!ExhDepartment.Value = 27,"Orange",(Fields!ExhDepartment.Value <> 27) AND (Fields!ExhibitionID.Value <> -1),"Red")

I have tried deleting various files RDL and DATA. I have tried uploading the file from report manager in IE and I have tried editing the file in report manager.

Hi,



I have been using the following code, (thanks to Shyam), to display address fields. This works great when using preview in BIDS, but the address shows on one continious line when the report is redered in Reporting Services.





=First(Fields!Name.Value) & IIf(First(Fields!Address1.Value) <> "", Chr(10) & Chr(13) & First(Fields!Address1.Value), "") &
IIf(First(Fields!Address2.Value) <> "", Chr(10) & Chr(13) & First(Fields!Address2.Value), "") &
IIf(First(Fields!Address3.Value) <> "", Chr(10) & Chr(13) & First(Fields!Address3.Value), "") &
IIf(First(Fields!Town.Value) <> "", Chr(10) & Chr(13) & First(Fields!Town.Value), "") &
IIf(First(Fields!County.Value) <> "", Chr(10) & Chr(13) & First(Fields!County.Value), "") &
IIf(First(Fields!Post_Code.Value) <> "", Chr(10) & Chr(13) & First(Fields!Post_Code.Value),



Any one any ideas?

Report Not Rendering In Report Manager

Dec 19, 2007



Hi All,
I have a report which gets data for around 5 different parameters for 5 servers. It needs to render different graph for each parameter, each server. It renders it properly (after running long though, which can be understandable) on the Visual Studio Preview. But when deployed on the Report Manager, it does not produce the graphs. It runs for long time and ends up with this error:


The following error was encountered:
We can not connect to the server you have requested.



This means that:
The server might be busy at this time.

The server is not reachable.

Please try later to see if you can go through.

Though I have configured the report execution NOT to time out. As such, subscriptions also do not work, It says, "Failure sending mail: An error has occurred during report processing."


So, has anyone faced similar problem and fixed it? If yes, can you please share the same?

Thanks a lot.

Manoj.

Report Rendering - Performance

As far as I know there are 2 ways to render the report in a Web page:
1. Using ReportViewer control and call its Render method
2. Using URL access

Which of the method is faster? As we are in the process of increasing the Performance of our Reporting Web Application.
I appreciate any suggestions in this regard.

Report Rendering/Exporting

Jan 10, 2008



My report is currently rendering about 50,000 rows and can still be increased.I am using SSRS 2005.I am exporting my rdls into HTML,Excel and PDF.My problem is when i export all the rows in PDF it won't continue and an error was produced.It says "Too many results, please constrain your parameters or try the other format."But using the same parameter which brings out the 50,000 rows,it works fine in HTML and Excel.

Which of the 3 rendering extension is the fastest in performance?Could it be HTML?What could be the reason why it wont work on PDF?Can't it contain such bulk record?Or is there anything can be done to solve the problem?
If anyone have encountered the same problem,we will be happy to hear from you.Any ideas and comments will be greatly appreciated..Thanks

HTML String Rendering In A Report

Jun 16, 2006

We have a "Comment" field that is saved as a HTML string to the DB. This field needs to be pulled into a report as rendered HTML.

I know this has been hashed out before, but has anybody found a good solution in the past couple of months?

We are thinking about storing two versions of the Comment in the DB: one with HTML, one as simple text. Has anybody found this an acceptable solution? I know it flies in the face of good DB design, but it seems the quickest, easiest solution...

Any word if this will be fixed in the next major release of SSRS? Can we expect this release any time soon?

Thanks for looking,

Horrible Report Rendering Performance

Feb 11, 2008



Hello! We are having a strange problem with Reporting Services 2005. Our RS server is located in a DMZ with the supporting RS database housed in our internal network. We have a batch of reports that perform well when rendering to browsers in our internal network. However, when accessing these same reports externally, the reports take a very long time to render. The difference between internal vs. external is huge; we are looking at maybe a minute tops to render the report from an internal browser vs. 10-15 minutes from an external client browser. The website and reports are setup for anonymous access, so it shouldnt be an authentication problem.

The RS execution log doesnt indicate much difference between the two. The data retrieval does take a little longer (only a second or two), according to the log, for an external request. But still, the times recorded in the Execution Log dont match at all what we are experiencing for external requests.

The various logs, both for reporting services and IIS arent picking up any anomalies either and Im at my wits end as to what else I can use to try and troubleshoot this problem. Has anyone seen this behavior before, or have any ideas what might shed some light on this?

Rendering A Report Using Custom Assembly

May 17, 2007

I have created a custom assembly and referenced it and the program builds successfully. When I try to run the report in design mode, it will not render, it throws an exception when it tries to create a PDF. When I remove the assembly, the reports work well. So I'm not sure what it is that I'm doing wrong - does anyone have any suggestions?



namespace Calculations

{

public class calcPercentage

{

public static decimal Percentage(decimal decValueOne, decimal decValueTwo)

{

decimal decPercentage = 0;

if (decValueOne == 0 || decValueTwo == 0)

{

decPercentage = 0;

}

else

{

decPercentage = (decValueOne - decValueTwo) / decValueOne;

}

return decPercentage;

}

}

}

Then in my textbox I put:

=Calculations.CalcPercentage.Percentage(SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_Sales"), SUM(Fields!PreviousYTDExpenseAmount.Value, "Template_OutputData_CGS"))



I referenced the assembly and added it to C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssemblies and I still get that error message so I do not know what the problem is.



The line where the exception occurs happens here:

byte[] bytes = MyReport.rvOutput.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);





Thanks so much for you help! If you have any suggestions about my next error...i'm all ears!
