Hi,
I have successfully created a "Radar with Markers" in the standalone report designer. The only thing missing is the line between the last dot and the first dot in each series. Is there a checkbox somewhere or is it my data source.

My data source looks like this:

Best regards,

Is there a method for dropping fields onto the report during design time. Like in MS Access where you can pull up the field list and drag and drop the fields onto the report rather than having to go through the process of dropping a textbox then going in and setting the binding. Its very time consumming when there are lots of textboxes. Also is ther a default setting for when you click the Value property of a control to open directly to the Fields rather than having to always click on it, seems like the vast majority of the times that is what is needed. Thanks for any help

Hi,

We have some library that specifically take a PrintDocument object and then handle printing in a very customized manner.  We would like to feed a rendered report to the library but it seems that there is no way for us to process the report and convert it to a PrintDocument.  

It seems that Telerik Reporting still make use of PrintDocument internally when performing report printing.  Is there anyway that we can get the PrintDocument from the processing engine?

Thanks~

Please help me to solve the problem.

I am trying to render a report as an image in my web service and return a byte[] to my client. The byte[] is then converted back into an image for display in the browser. From my debug sessions, I can see that byte[] does have data in it and the view appears to have a correctly sized image; however, the image is completely blank.

This report in particular requires one Integer parameter, ArgID, to be passed in. Blank values can not be accepted. Below is the code I am using (function names and arguments have been modified for brevity).

Web-Service code to render the report as an image:

View file img tag:

Action called from img tag:


I've only just started using Telerik Reporting over SSRS and would like to make the case for switching to Telerik for a long-term solution if I can manage to get programmatic generation working within specifications. Any and all support is greatly appreciated.

Thank you,

I have a DLL with a report. When I go from design mode to preview in VS the report constructor is executed and it does what's required.

Using the stand-alone designer I import the DLL, and on initial creation the constructor is invoked - twice actually. But from then forward, it's never invoked on preview or at any other time.

I created a Windows Form with a report viewer, set the ReportSource to the TRDX via a URL/file reference. Same thing - ODS is called but the report constructor is never invoked.

I'm using the ODS only to retrieve design-time schema. At run-time I'm using report parameters to determine what data to return, and the ODS is invoked manually from NeedDataSource. Someone might think I need to set the ODS to null in the constructor. Again, the constructor is not being called.

The stand-alone designer does show my class name "ReportTemplate" in the Property Browser. So I know it found that class. My report has the ODS pre-loaded, and when the designer first opens that ODS is there, obviously coming from execution of the InitializeConstructor() method, executed from my constructor. So On initial creation it finds what it needs in that class.

From the report viewer, the interactive mode does display a text box that was placed for the header. So it seems InitializeComponent() is getting executed for that report, but nothing else. This is very confusing. It's almost like the report base class is getting executed but not my derived class - and once a report is imported, the derived class isn't invoked anymore. Or perhaps I just don't know what setting to check to get it to instantiate my report class at run-time. Maybe it's a namespace issue and at run-time it can't find my report class within my namespace.

Side note: Originally the interactive mode did not display that report header, but going to preview mode it did. My ODS is returning a DataTable with columns defined and no rows. When I changed that to return a single row of null column data, interactive mode started to show the header too - it's like a null DataSource causes one mode to not render anything but it's different in the other mode. I dunno if anyone would call that a bug but it's certainly slightly anomalous behavior.

Thanks.

I just started using telerik reporting and I can't figure out how to get a marker symbol to show up for my line series.

I am using a Graph control with 1 line series. On the series, I have specified MarkerMaxSize, MarkerMinSize, MarkerSize, and MarkerType, but I still don't see these symbols along my line.

Hi team,
I use an object data source in my report and when I check the preview mode I get an error but if I use the report in report viewer in aspx and run the page i don't get any error.

first i want to know how to debug my business method when I use the preview mode in my report to not always have to run my aspx screen to do the debugging process.

second i want why i get this error, kindly find below the details :

my business method is very simple :

 [DataObjectMethod(DataObjectMethodType.Select)]
        public List<CreatedQRCodesCountBEL> GetCreatedQRCodesCount(int SuperAcctID) { //my code } 

in my report i have one report parameter "SuperAcctID" and i just give it a default value no binding to data source:
An error has occurred while processing Report 'rptCreatedQRCodesCount': 
An error occurred while invoking data retrieval method. 
Try restarting Visual Studio. ------------- InnerException ------------- 
Exception has been thrown by the target of an invocation. ------------- 
InnerException ------------- Object reference not set to an instance of an object. 

in my aspx code behind i do the below and it is working without the error:

protected void Page_Load(object sender, EventArgs e)  {
        if (!IsPostBack) {
            var objCreatedQRCodesCountReport = new rptCreatedQRCodesCount();
            objCreatedQRCodesCountReport.ReportParameters["SuperAcctID"].Value = SuperAcctID.ToString();
            radrvCreatedQRCodesCount.ReportSource = objCreatedQRCodesCountReport;
        }
    }

I hope you can help me.

I'm playing along with TelerikReporting-LearningGuide.pdf.

I've created a class library and am trying to create the Report Viewer app.

It's a Windows Forms app; I had to change from targeting .NET 4 Client to .NET 4 for the Telerik Reporting Q1 2013 controls to display in the Toolbox (I first tried using a Visual-Studio native ReportViewer control, as the tutorial simply says "ReportViewer," and doesn't specify that it means the Telerik ReportViewer.

I added the class library I created previously in the tutorial to my project References.

Anyway, I drop the Telerik ReportViewer on a form, and locate its Report.ReportSource property. It invokes the "Load a Report From ..." dialog that gives me options of URL or file, Type name, Object instance, or XML markup. I tried both "URL or file" and "Type name" but neither of them want to accept the .dll that I already added as a reference.

Of course, that makes sense, because it doesn't make sense I would have to add the class library/.DLL as a project reference AND then choose it as the report. But what *am* I supposed to choose? I searched my hard drive for *.tr* in Windows Explorer, and the only "trdx" files it finds are 9 that come with the Telerik download.

The tutorial is a little long in the tooth (2008), but I couldn't find an updated version of it. Am I missing something because the process has changed, or...???

Hi
 I'm making a report in which i have a table consisting of two columns, let we have ColumnA and ColumnB, the values of ColumnB
are grouped by ColumnA. The report generates a separate cell for every value of ColumnB but I want  all the values of ColumnB that belongs to a particular value of ColumnA to be in one cell, separated by comma. 

I've attached a snapshot of the two columns, and what I'm doing is to put the values of the 2nd column in a single cell separated by comma. Your help would be greatly appreciated and Sorry for my poor english, I hope you understand it.

Thanks
