Telerik Team,

I am having an issue with a crosstab report. I have created a small demo project that easily shows the issue, much faster than typing out several paragraphs and code snippets to try and describe it.

I have zipped the file but cannot upload with your file attachment tool below. (only image files allowed)
Is there anyway I can send the zipped file to you and associate with this thread?

Thanks.

Export to PDF programmatically Lost Background

Hello all,

I have a report that contains a chart. In the chart plot area, I set the background image using relative path (~/Image/myimage.png). Everything works as expected using ReportViewer on asp.net page. The problem I have is when I export the report to pdf format programmatically, the chart background is not set.

Here is how I export it.

public Stream GetReportBytes(Guid studyId, string userName)

{

ReportProcessor reportProcessor = new ReportProcessor();

Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();

ProjectReport reportToExport = new ProjectReport();

reportToExport.ReportParameters[0].Value = studyId.ToString();

reportToExport.ReportParameters[1].Value = userName;

instanceReportSource.ReportDocument = reportToExport;

RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);

return new MemoryStream(result.DocumentBytes);

}

And background image is set like this

MainChart.PlotArea.Appearance.FillStyle.FillSettings.BackgroundImage = "~/Images/ci_bg.png";

Please advice.

Cheers!

Report from generic list?

Before calling my report, I generate a generic list of business objects. The processing is quite complex and I do not want to try to use Telerik's parameter facility to do this.

How can I pass this List<BusinessObject> to Telerik Reporting at runtime? What do I use as a datasource in order to design the report?

I am using VS2010 and Report Q1 2011.

(Sorry I mis-posted this issue in the Winforms area - could not move it)

Need parent - multiple child report (or how to simulate multiple detail sections)

I have a report that has a single parent (Patient) and multiple children (test results, recommendations, background information) with forced page breaks before each section. This is NOT a hierarchy it is distinct sets of information for the patient.

In other products that I am familiar with you would create multiple detail sections but i understand from reading that this is not supported. I've tried to simulate this feature with groups but there only seems to be one hierarchy of groups.

I've tried dropping each logical detail section in panels but:
a. there does not seem to be a way to create a page break for a panel
b. keeptogether does not always work as I would expect when the height of the section changes (i.e. if the kept-together section is longer than a page the first lines of it will be pushed to the prior page rather than creating a page break)

I am using report designer and pushing the XML report definitions to a server and then running them from there so assembling a set of subreports is not practical.

Any suggestions would be greatly appreciated.

[Solved] Report datasource avalaible at run time

Hi!

I create a trdx report in Telerik Report Designer. After I added this report to my project.

Telerik.Reporting.UriReportSource uriReportSource = new Telerik.Reporting.UriReportSource();

uriReportSource.Uri = @"Report\teszt.trdx";

TelRptViewer.ReportSource = uriReportSource;

I want to add a dataTable to report programatically. So my data is not avalible at design time.
I check some topic in help.
Working With Data at Design Time

"In this case you would have to mock your data just to enable the Report Designer to show any data schema. "
I don't understand this. How it is possible?

I already check this links too.
Using the NeedDataSource event to connect data
How to: Bind to a DataTable

How to handle errors/exceptions?

Hi there,

I really want to let the users know whenever an error or exception occurs while a report is generated. I use a ReportViewer to display my reports and I have an errorlabel placed above the viewer.

It is possible, due to rights, that a user cannot retrieve certain data and therefore the viewer throws an error message, but I want to show an "informative" message in an errorlabel outside the report, above the viewer itself on the .aspx page. Whenever this error or exception occurs I want to NOT generate the report (just abort it and show no report) and display corresponding error message in the errorlabel on the aspx page.

In my code-behind of my .aspx page I have the following:

CustomReport customReport = new CustomReport();

// ...set reportparameters...

this.ReportViewer.Report = customReport;

// report is getting generated and viewer shows an error

For all of you, I don't use a ReportProcessor, so the Error event of it cannot be used. The Error event of the report itself cannot be used as well, because it's located in another DLL and not accessible in my .aspx page. So why isn't there an event such as the Error event of the ReportProcessor and report for the ReportViewer?

I really want to solve this, because I don't want to show the users a report with only an error in it. I don't want to show the report at all if an error/exception occurs and this error/exception details should be displayed in the errorlabel.

Looking forward to a solution or workaround! Thanks in advance!

Regards,
Datamex

Setting listeners for reports built in stand-aloneTelerik Report Designer

We are developing a reporting system for an enterprise web application. The report definitions (*.trdx) are all being built using the stand alone Telerik Report Designer so there is no code behind pages associated with the definition files. One of the business requirements is to save sets of parameter values for each report. I have devised a way to show just the parameters area of a report, but I am not able to access the values set by the user. All the documentation and other forum threads state that I should be able to hook up listeners to the ReportDocument ItemDataBinding and ItemDataBound events. I have done that, but the event handlers are not being triggered when a user sets a value and the report viewer refreshed the data.

Here is the setup:

A report viewer object is added to an .aspx page (C#).
In the code behind, the report definition file is loaded, deserialized and attached to the report viewer via the ReportSource



   var reportDefinitionFile = Server.MapPath("~/app/reports/repository/rpt/" + _reportPath);   

   var xmlSerializer =

new

ReportXmlSerializer();

   reportDocument = (Telerik.Reporting.Report)xmlSerializer.Deserialize(reportDefinitionFile);

   var reportSource =

new

InstanceReportSource();

   reportSource.ReportDocument = reportDocument;

   trdParameters.ReportSource = reportSource;

trdParameters is the report viewer control. reportDocument is a private variable at the Page level and has been hooked up the listener reportDocument_ItemDataBound:

protected override void OnInit(EventArgs e)

{

reportDocument.ItemDataBound += new EventHandler(reportDocument_ItemDataBound);

base.OnInit(e);

}

private void reportDocument_ItemDataBound(object sender, EventArgs e)

{

Telerik.Reporting.Processing.Report rpt = (Telerik.Reporting.Processing.Report)sender;

var obj = rpt.Parameters;

}

When the page is called, the parameters are rendered properly and the report generates properly but event handler is never triggered. Any time a user changes a parameter, the report viewer makes an AJAX call to the Telerik reporting dll and I cannot find a way to intercept that.

I am using Q1 2013 version of Telerik Reporting.

Any ideas?
