I have configured my Telerik Reporting to use cache provider = File and everything is working just fine.
I notice that that the report files is generated in a sub folder with a name that looks something like a guid, but I can't find anything in the documentation that verifies this assumption.

Since I run several customer on the same web-server, using the same web.config, and there for the came cache directory, I'm a little bit nervous that a customer possible could get another customers data.

Can someone verify that the generated name for the sub folder created is a guid?

Regards

I am considering giving some users the stand alone designer so they can make some of their own reports.  I know one question that will be asked, "if we make a report we like, how do we get it in our web site?"  In other words, they prototype reports and play around with them.  When they get one they like a lot, they would want me to put it in the VS project so they can view it in the main web site.

So, the report designer saves to a .trdx file.  But the project files are code (vb or cs).  So how to do the import?  I would have expected an "Import trdx file" in the VS Telerik Reporting menu.  Am I missing something? 

Thanks.

Hi Telerik,

Is it possible to have a single textbox display formatted values for multiple data fields? Specifically my issue is I want to display a date interval in the same textbox where the start and end dates are in two individual datafields of type DateTime, like so:

"01/01/2001 - 07/01/2001"

I want to utilize the localization and formatting capabilities of having the dates as DateTime types and therefore combining them in codebehind as a string is not an option for me, then I would rather have two separate textboxes - BUT having two separate textbox then present me with the problem of proper displaying in the report if the formatting changes (longer or shorter datetime string).

I was trying to do something like this:

=Format("{0:d}, {1:d}", Fields.FirstDistributionDate, Fields.LastDistributionDate)

Thanks in advance,

Best regards,
Kasper Schou

Hi,

I'm using Telerik Reporting Q1 2013 and I have a report which contains a subreport which I have been able to export to HTML, PDF, CSV, etc., etc., programmatically, but it throws an exception when attempting to export to Excel (XLS/XLSX).  I can export a different report that I have (which contains no subreport) to all formats (including Excel) without any exceptions.  As far as I can tell, the only real difference between the two is the subreport.

I get a Null Reference Exception when calling the RenderReport method of the ReportProcessor class.  Here's the stack trace:

{"Message":"An error has occurred.","ExceptionMessage":"Object reference not set to an instance of an object.","ExceptionType":"System.NullReferenceException","StackTrace":" at Telerik.Reporting.ExcelRendering.RenderingItem.Render(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.RenderingItemContainer.RenderInternal(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.Table.RenderInternal(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.RenderingItem.Render(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.RenderingItemContainer.RenderInternal(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.Section.RenderInternal(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.RenderingItem.Render(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.Group.RenderInternal(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.RenderingItem.Render(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.RenderingItemContainer.RenderInternal(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.Report.RenderInternal(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.RenderingItem.Render(IWorksheet worksheet, TableLayoutInfo layoutInfo)\r\n at Telerik.Reporting.ExcelRendering.Report.Render(IWorkbook workbook)\r\n at Telerik.Reporting.ExcelRendering.Excel97.ExcelReport.Telerik.Reporting.Processing.IRenderingExtension.Render(Report report, Hashtable renderingContext, Hashtable deviceInfo, CreateStream createStreamCallback, EvaluateHeaderFooterExpressions evalHeaderFooterCallback)\r\n at Telerik.Reporting.Processing.ReportProcessor.RenderCore(ExtensionInfo extensionInfo, IList`1 reports, Hashtable deviceInfo, IRenderingContext renderingContext, CreateStream createStreamCallback)\r\n at Telerik.Reporting.Processing.ReportProcessor.ProcessAndRender(String format, ReportSource reportSource, Hashtable deviceInfo, IRenderingContext renderingContext, CreateStream createStreamCallback)\r\n at Telerik.Reporting.Processing.ReportProcessor.ProcessAndRenderStateless(String format, ReportSource reportSource, Hashtable deviceInfo, IRenderingContext renderingContext, CreateStream createStreamCallback)\r\n at Telerik.Reporting.Processing.ReportProcessor.RenderReport(String format, ReportSource reportSource, Hashtable deviceInfo)\r\n at CPSReporting.TelerikCPSReportProcessor.RenderExcelReport(CPSReportDefinition reportDefinition) in c:\\Code\\CPS_SVN_REPO\\CPSReporting\\trunk\\TelerikCPSReportProcessor.cs:line 78\r\n at CreditPoint.Web.Controllers.WebAPI.ReportController.PrepResponse(HttpRequest request) in c:\\Code\\CPS_SVN_REPO\\Web\\branches\\RB-4.6\\Controllers\\WebAPI\\ReportController.cs:line 69\r\n at CreditPoint.Web.Controllers.WebAPI.ReportController.Post() in c:\\Code\\CPS_SVN_REPO\\Web\\branches\\RB-4.6\\Controllers\\WebAPI\\ReportController.cs:line 27\r\n at lambda_method(Closure , Object , Object[] )\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass13.b__c(Object instance, Object[] methodParameters)\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.<>c__DisplayClass5.b__4()\r\n at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"}

I believe the stack trace is the same for both XLS and XLSX device formats.  As I said, this is only happening with one of my reports (which happens to contain a subreport).  All other reports work just fine when exporting to Excel.

Here's the code:

InstanceReportSource instanceReportSource = new InstanceReportSource();
XmlReaderSettings xmlReaderSettings = new XmlReaderSettings();
xmlReaderSettings.IgnoreWhitespace = true;
ReportXmlSerializer serializer = new ReportXmlSerializer();
XmlReader primaryReportXmlReader = XmlReader.Create(reportDefinition.PrimaryReport.TemplateLocation, xmlReaderSettings);
Telerik.Reporting.Report primaryReport = (Telerik.Reporting.Report)serializer.Deserialize(primaryReportXmlReader);
primaryReportXmlReader.Close();
this.SetConnectionStrings(ref primaryReport, reportDefinition.ConnectionString);
instanceReportSource.ReportDocument = primaryReport;
if (reportDefinition.PrimaryReport.ReportParameters != null)
{
    foreach (KeyValuePair<string, object> item in reportDefinition.PrimaryReport.ReportParameters)
        instanceReportSource.Parameters.Add(this.CreateParameter(item.Key, item.Value));
}
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();               
    this.SetConnectionStrings(ref subReportInstance, reportDefinition.ConnectionString);
    Telerik.Reporting.SubReport subReport = primaryReport.Items.Find(cpsSubReport.ReportName, true).FirstOrDefault() as Telerik.Reporting.SubReport;
    ReportSource subReportSource_Type = subReport.ReportSource;
    InstanceReportSource subReportSource_Instance = new InstanceReportSource();
    subReportSource_Instance.ReportDocument = subReportInstance;
    foreach(Telerik.Reporting.Parameter param in subReportSource_Type.Parameters)
        subReportSource_Instance.Parameters.Add(param);
    subReport.ReportSource = subReportSource_Instance;
}
Hashtable settings = new Hashtable() {
    { "UseNativePageHeader", false },
    { "UseNativePageFooter", true },
    { "ShowGridLines", false }
};
//Exception thrown here:
RenderingResult result = _reportProcessor.RenderReport("XLS", instanceReportSource, settings);
return result.DocumentBytes;

Thank you in advance,
An otherwise extremely happy Telerik user  :)

Hi there!

We’ve identified that the reporting component returns verbose error messages with a 200 HTTP status code, making our application vulnerable to XSS attacks. 

Please could you contact us privately, as soon as possible for more details.

Thanks, in advance.

Hello,

1. I need the image filter (ie, it must allow only image files) when i click Select Button in RAD UPLOAD control and not in validation.

2. I change "a.doc" files extension as "a.jpeg" and trying to upload the "a.jpeg" file. How to stop uploading the a.jpeg file as because it's not an image file.
How to do validation using java script?

Hello,

I see that the converter is still stuck on (now very old) ActiveReports 3 series. I have a myriad of reports I would love to bring into the Telerik fold, but don't have the resources to rewrite from scratch.

Is there any hope of seeing a 6 or 7 converter in the future? I can see from 2009 posts that it was "in the works".

Best,

John

I have successfully implemented the PrintReport method found here: http://www.telerik.com/help/reporting/m_telerik_reporting_processing_reportprocessor_printreport.html

But, I find that that when I use identity impersonation to allow this code to work (configured via web.config), the impersonated account needs admin rights on the web server.  Our network admin would prefer to give specific rights to this account, vs. just adding to the administrators group.  Can you tell us what those would be?  He thought maybe a temp file was being created somewhere on the server to support the printing.

Thanks in advance!
