Recently we upgraded our version of Telerik Reporting.  In a few of our reports, the way we were accessing the report param selected values in the code behind broke, but we made the necessary corrections to access the parameter values.

However, we still have a scenario where I can't seem to access the values of the report parameters...

We have a aspx page that contains a telerik ReportViewer.  Also on the page, we have a save button - that allows them to save the parameters they have selected in the report that is displayed in the ReportViewer.   So in the code we get the ReportSource of the ReportViewer, and then pull the values of the parameters, and save them to the database.  When we upgraded (to Q1 2013), this stopped working. (the values for the parameters are always null (or the default))

We were accessing the parameter like this:

 

Is there a way of getting the parameter values?

I have tried reading the documentation provided and searching online, but  i have no idea where to start when it comes to a chart.  I have a sql query generating a report in VS 2010 connecting to a sqldatasource.  I want to create a chart but cannot seem to get it to work properly.  Does anyone know of a good guide or place to get an overview or a video to watch on how this works from start to finish, even on a simple example.  I think once i get the idea i can extrapolate from there. thanks for the help.

Before using session state in IIS reports worked fine, but then we implement session status reports stopped working. He shows me the following error.

" Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and consequently, non-serializable objects or MarshalByRef are allowed. The same restriction applies if the store custom session state performs a similar serialization in 'Custom' mode. "

I appreciate a prompt response. Thank you.

Hello,

I'm load testing my application right now. It consists of a web app which is calling a WCF Rest service to render the a report in PDF.

When we are sending 5 requets from 5 differents tabs of the browser, we realized that every report are rendered one after the other. As they are large reports about 4 minutes to render. I'm wondering if there is a way to configure the ReportProcessor in order to parallelize the rendering?

Thanks in advance for your help,

See in attachment, a graph of CPU, memory and IO. large IO spikes is basically when the app is writing a report to the disk.

I have been working around telerik reports for many days. This time I needed to put up a chart on my report as well. I have XML data (coming from database) to been shown in report, plus to make chart from very same data. I did same as described in http://blogs.telerik.com/kevinbabcock/posts/09-02-06/bind_your_telerik_reports_to_xml_data.aspx to deal with xml. I have only two columns to be shown as text values (what I have done exactly as described in link), Then I those two columns on left side and placed a chart on right hand side. And populated it in NeedDatasource event. But chart is repeating for every data on left hand side. Please tell me what am I missing over here?

Hello,

I made a report with 4 crosstabs in detail section (I want to avoid doing subreports)
The report doesn't have datasource but each crosstab has its own datasource.
In the ReportFooter section i want to show a general total (The sum of crosstabs's total cells).

Example :
Crosstab1 total cell  = Sum(Fields.AcResult) = 1000
Crosstab2 total cell = Sum(Fields.VeResult) = 500
Crosstab2 total cell = Sum(Fields.PaResult) = 0
Crosstab2 total cell = Sum(Fields.CcResult) = -100
ReportFooter total should be 1400

How can i define the reportfooter total  textbox value ?

Thank you for your help

Hello,

We are developing a web service that loads TRDX files that users created into XmlReportSource and renders PDF files and send back to web clients using RenderReport of a ReportProcessor object. In TRDX files, our users want to set two parameters in SQL to create a SQL statement that contains BETWEEN with a begin date and a end date and use just one parameter to pass in, separated by commas.

The SQL statement is something like:

SELECT * FROM APPLICANT
WHERE DATE_CREATED BETWEEN @BeginDate AND @EndDate

Since our users have accustomed to pass just one parameter to accomplish this, they are unwilling to create two report parameters: one for begin date and one for end date. They want to create just ONE report parameter to basically parse the report parameter value into two SQL parameter values.

I have created a report parameter type string that receives the begin date and the end date separated by a comma ex. 1/1/2013,12/31/2013.

In the data source side, I would like to do something like:
Parameters:
Name: @BeginDate
Type: DateTime
Value:=CDate(Split(",",  Parameters.ReportDate.Value[0]))

Name: @EndDate
Type: DateTime
Value:=CDate(Split(",",  Parameters.ReportDate.Value[1]))

Of course this give me errors at [ characters.

Is there anyway to define the parameter?

Thanks
