RenderReport TIFF fails when only one page & TiffCompression = ccitt4

Can someone please tell me what is incorrect with the following code. It only fails when the TIFF is one page.

Public Sub CreateProcessNotesTIFF()

Dim instanceReportSource As New Telerik.Reporting.InstanceReportSource()

instanceReportSource.ReportDocument = New ProcessNotes

instanceReportSource.Parameters.Add(New Telerik.Reporting.Parameter("ProcNo", _procNo))

instanceReportSource.Parameters.Add(New Telerik.Reporting.Parameter("ApplicantName", _applicantName))

Dim reportProcessor As New Telerik.Reporting.Processing.ReportProcessor()

'set any deviceInfo settings if necessary

Dim deviceInfo As New System.Collections.Hashtable()

deviceInfo("OutputFormat") = "TIFF"

deviceInfo("TiffCompression") = "ccitt4"

deviceInfo("DpiX") = 300

deviceInfo("DpiY") = 300

'deviceInfo("DpiX") = 120

'deviceInfo("DpiY") = 120

'Dim result As Telerik.Reporting.Processing.RenderingResult = reportProcessor.RenderReport("PDF", instanceReportSource, deviceInfo)

Dim result As Telerik.Reporting.Processing.RenderingResult = reportProcessor.RenderReport("IMAGE", instanceReportSource, deviceInfo)

Dim fileName As String = result.DocumentName + "." + result.Extension

'Dim path As String = System.IO.Path.GetTempPath()

Dim path As String = System.IO.Directory.GetCurrentDirectory()

Dim filePath As String = System.IO.Path.Combine(path, fileName)

Using fs As New System.IO.FileStream(filePath, System.IO.FileMode.Create)

fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length)

End Using

End Sub

The following code has TiffCompression commented and both single and multiple page TIFFs are exported

Public Sub CreateProcessNotesTIFF()

Dim instanceReportSource As New Telerik.Reporting.InstanceReportSource()

instanceReportSource.ReportDocument = New ProcessNotes

instanceReportSource.Parameters.Add(New Telerik.Reporting.Parameter("ProcNo", _procNo))

instanceReportSource.Parameters.Add(New Telerik.Reporting.Parameter("ApplicantName", _applicantName))

Dim reportProcessor As New Telerik.Reporting.Processing.ReportProcessor()

'set any deviceInfo settings if necessary

Dim deviceInfo As New System.Collections.Hashtable()

deviceInfo("OutputFormat") = "TIFF"

'deviceInfo("TiffCompression") = "ccitt4"

deviceInfo("DpiX") = 300

deviceInfo("DpiY") = 300

'deviceInfo("DpiX") = 120

'deviceInfo("DpiY") = 120

'Dim result As Telerik.Reporting.Processing.RenderingResult = reportProcessor.RenderReport("PDF", instanceReportSource, deviceInfo)

Dim result As Telerik.Reporting.Processing.RenderingResult = reportProcessor.RenderReport("IMAGE", instanceReportSource, deviceInfo)

Dim fileName As String = result.DocumentName + "." + result.Extension

'Dim path As String = System.IO.Path.GetTempPath()

Dim path As String = System.IO.Directory.GetCurrentDirectory()

Dim filePath As String = System.IO.Path.Combine(path, fileName)

Using fs As New System.IO.FileStream(filePath, System.IO.FileMode.Create)

fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length)

End Using

End Sub

Working with SubReports programmatically

Hi,

I'm using the ReportProcessor class in order to export reports in an HTML format progmmatically. I have a couple of questions; I'm about at wit's end, here.

I have a report which contains a sub report. Each of these reports is encapsulated in a TRDX file. I create an instance of the main report (let's call it MainReport), which is of type Telerik.Reporting.Report. I get a reference to MainReport's DataSource property, which is a SqlDataSource, and I set the ConnectionString property to a connection string in my app.config file. I then instantiate an InstanceReportSource and set the ReportDocument property to my MainReport object. At this point, I can render the main report via the ReportProcessor.RenderReport method. All is well and good so far.

My problem is with the sub report. What do I need to do to include it? I've looked at the limited amount of documentation over and over but I simply cannot wrap my head around what I need to do. Here's what almost works:

I create an instance of the sub report the same way I'm instantiating MainReport (we'll call it SubReport). I then Find() the sub report item within MainReport's Items collection, and after grabbing that reference, I set its ReportSource property to my SubReport instance.

Here's the problem with that: Apparently this way of doing things is obsolete. I need to know how to do it correctly. Also, I need SubReport.DataSource.ConnectionString to be the same as MainReport.DataSource.ConnectionString. Additionally, there is a Crosstab item within the main report that apparently also needs a ConnectionString, even though the DataSource is the same as MainReport's DataSource.

Here's some code snippets:

//MainReport instantiation (some code is hidden, but you should get the idea

XmlReaderSettings xmlReaderSettings = new XmlReaderSettings();

xmlReaderSettings.IgnoreWhitespace = true;

ReportXmlSerializer serializer = new ReportXmlSerializer();

XmlReader primaryReportXmlReader = XmlReader.Create(reportDefinition.PrimaryReport.TemplateLocation, xmlReaderSettings);

_primaryReport = (Telerik.Reporting.Report)serializer.Deserialize(primaryReportXmlReader);

primaryReportXmlReader.Close();

SqlDataSource reportDataSource = (SqlDataSource)_primaryReport.DataSource;

reportDataSource.ConnectionString = reportDefinition.ConnectionString;

this._instanceReportSource.ReportDocument = _primaryReport;

//We're using a custom class to define a "report definition", which contains data about sub reports,

//so I'm looping through each sub report definition and instantiating it.

foreach (CPSReport cpsSubReport in reportDefinition.SubReports)

{

XmlReader xmlReader = XmlReader.Create(cpsSubReport.TemplateLocation, xmlReaderSettings);

Telerik.Reporting.Report subReportInstance = (Telerik.Reporting.Report)serializer.Deserialize(xmlReader);

xmlReader.Close();

SqlDataSource subReportDataSource = (SqlDataSource)subReportInstance.DataSource;

subReportDataSource.ConnectionString = reportDefinition.ConnectionString; //would be handy to automatically get from the main report

//The following line is hardcoded for now because i've been experimenting.  The string "subReport1" would actually be defined in our custom report definition class.

Telerik.Reporting.SubReport subReport = _primaryReport.Items.Find("subReport1", true).FirstOrDefault() as Telerik.Reporting.SubReport;

subReport.ReportSource = subReportInstance; //obsolete. what's the right way to do this?

}

Also, as I mentioned, in the rendered report, I get an error about the Crosstab connection string:

An error has occurred while processing Table 'crosstab2': Unable to establish a connection to the database. Please, verify that your connection string is valid. In case you use a named connection string from the application configuration file, make sure the name is correct and the connection string settings are present in the configuration file of your application. ------------- InnerException ------------- Format of the initialization string does not conform to specification starting at index 0.

Please help? :)

Thanks!

How do I get a trdx report to display in a reportviewer in ASP.net?

I must be dense or something, but for the life of me, can't figure out how to get a report viewer control to display a report.
I need to dynamically set the report location and SQL server connection string in the code behind. The reason for this is,
I want to call the report viewer from multiple areas in my asp.net application and populate it with different reports. Also, the
SQL connection string resides in the web.config and is encrypted. I need to decrypt the string before passing it on to the
report to use. Some reports are single layer and others have sub-reports in them.

So, how do I do this in the code behind of a web form? Source code example would greatly be appreciated.

Thanks!

Grouping Experssion and IsEmpty

I have a group (county) which can have data or be empty. How can I change the group expression, to group data when group field is empty, and group matching criteria. Is there a way to add a second grouping to a group and change "IsEmpty" to true?

Direct Print and OCR behind

Hi there,

we are evaluating telerik reporting engine!

We want to generate reports that should be printed automaticly to a networkprinter. I coded this (VB.net and WinForms) from the examples here:

http://www.telerik.com/help/reporting/m_telerik_reporting_processing_reportprocessor_printreport.html

The printer itself is a tool which analyses the document and depending on its content adds some barcodes. But this does'nt work. Because the Printer gets an image with a lower resolutions as needed, the OCR of the tool didn't recognizes anything und the workflow fails.

Is there a way to solve this problem?

Even if I Export the Report first to PDF the OCR fails. The only way is to Export it as RTF and then print it from MS Word, but this is not applicable on all Clients!

Regards

Torsten

Report Localization Issue

The reports we are using in our project have a main report and couple of sub reports embedded within them. The report dll we are using is Version 6.2.12.1017. We are using report viewer for Silverlight for displaying the report.
The default language for the reports are English(US). When a report is loaded in the report viewer for the 1st. time, all the localizations take effect perfectly.

But, if the same report is refreshed or regenerated for some new parameter (not the 1st, time load) it fails to localize properly. In this case (refresh or change in parameter) only the sub reports are displayed with the right language. But the label texts in the main report show up in the default language.

I have checked on the server side where report is generated that the current culture of the thread is correct (not the default English). Yet, the conversion does not take effect in only the main report texts even though the sub reports embedded within it work perfectly.

Our product is already in Beta phase. Hence, we are in urgent need of resolution for this. Hope, you can help us with this.

Regards,

Hyperlink from one report to another report

Hi,

I created a report category which include a list of reports. I can link to a report, for example report A. However if I also have a textbox in report A
whose action links to another report B, I cannot link to B. The cursor is not like hand.

Report preview all works fine. It just doesn't work when displaying report from html5 report viewer. Do I have anything wrong?

Thanks.
