Hello,
with the latest production release.
Error message:
Object reference not set to an instance of an object.
I have a site that allows users to upload images to the report. The users can upload as many images as they want and the images get appended to the report.
The report viewer initially contains a report and the users images are appended at the button of the report. The way I append the images: I have created a one page report that has an image in the middle of the report. I iterate through all the image paths and add a new report for each image.
Here is an example of when the report processes the error. When a user adds 1 image and renders the report the report view looks great but once they add more images and try to render the report the report view crashes.
Below is the Error and Stack Trace:

Here is the way I append the images in the resolver
// Add File Attachment to report

// Gets the paths
var pngImagePaths = ReportDataMethod.GetFilePaths(eFormID);
if (pngImagePaths != null)
{
var pageCountID = 1;
foreach (var imagePath in pngImagePaths)
{
// Add cover page (Eventually we will add this to all E-Forms
// Add scanned file
// note that setting filePath or File Resource Name to null will
// cause the preview to crash on reload
PDFToImageParameters fileParams = new PDFToImageParameters()
{
FilePath = imagePath,
FileResourceName = "",
ImageExists = true,
IsEmbeddedResource = false,
PageCount = pageCountID
};
var fileReport = UpdateScannedImageReportWithParams(eFormID, pageCountID == 1 ? "File Attachment" : String.Empty, pageCountID++, fileParams);
book.Reports.Add(fileReport);
}
}
Any help would be appreciated.

Hi,
I'm getting error - Value cannot be null. Parameter name: instance, after I upgraded my solution to the current telerik reports verson. Can you please let me know how I can fix this issue.
Please see the attached file for more information.
Thanks.
I am trying to change report definition dynamically but unable to bind datasource. Could you please help me in binding the datasource dynamically. I amusing LinqtoSQL as datasource.
On click of a button, I am calling the constructor of my report and getting the report document and setting it to InstantReportSource's report document.
I am serializing the report document to XML file and making modifying the report definition.
After deserializing, how to bind the datasource before inputting the report to report viewer.
Thanks

Hello,
I am evaluating a trial version of the Standalone Report Designer and have two reports I want to link via Drillthrough.
I believe I have followed the correct procedures to select the "interactive" field and set up the corresponding next steps:
Edit Action > Navigate To Report > Select Report Source > URL or File
Both of my reports are published to our telerik server in the same folder / category. However, when I key the URL in the source box, add proper parameters, and preview, I am receiving the following message:
"Unable to get report parameters.
An error has occurred.
'https://telerik.justfab.net/Report/View/LMS_DEV/Department_Overview_Report' report cannot be found."
This is a valid URL for the report I am trying to link to, but assuming from the error message there must be some other way to reference the URL for an existing report that already resides on our server. I tried adding .trdx extension with no success.
Please let me know the proper URL format to use when setting up simple Drillthrough connection between two reports residing on the same server.
Thank you!
I'm working on a calendar report that uses a daily sub-report for each day of the month.
The issue I'm running into is that with auto-scaling, each day scales differently based on the data for that day, meaning that the sub-reports are all displayed using different scales, and so don't lend themselves to side-by-side comparison.
It's impossible to know before run-time what the maximum scale for the entire month will be, so I can't hard set the axis scales either. Is there a way to 'pass in' the required scale to the sub-report along with the other parameters? I tried to put a formula in the CoordinateSystem.YAxis.Scale.Maximum property, but it seems to only accept a hard value and not a formula.
Hi,
In my WPF app, I have a report designed by default for A4 paper and I want to fit it to print on an A5 printer.
I have read threads on this forum about the ViewerPrintScaling (especially this one http://www.telerik.com/forums/dynamic-report-column-size#R757mvc1xkKirZXyJj7MBw) and I tried to used this option.
Here are the results :
- works fine when I generate a pdf file on disk using the ReportProcessor.RenderReport function, then print-it with right-click
- does not work in ReportWiewer (always printed in A4)
- does not work when directly printing using the ReportProcessor.PrintReport function (always printed in A4)
Am I missing something ? When I read the comment of Stef from Telerik Team, I understand that this option is always taken in account, either when rendering or when directly printing...
Thanks by advance for your help,
Aurélien
