Is there a way to trigger a custom action when a user clicks on a record? Basically I have a report view showing several records. When the user clicks on a row, I'd like to execute code based on the row's ID that they clicked. Seems straight forward but I don't see anything in the documentation other than bookmarks and URLs.

I have a program that gets some data from a database and prints a report to a printer on schedule. It runs unattended so there can never be user input. I have it printing to the default printer, but I'd like to print to a defined network printer (\\servername\printername). 

How can I code that?

Is there any way to export my report as JPEG?

I'm used to designing my report by Telerik ASP.NET MVC report .

Hi;

I would like to know how to build a report with a customized graph. It is specifically for a customization report but the question is general in the aspect of how to customize a graph. 

An attached bitmap has been added witha graph output I'd like to achieve.

Hello,
with the latest production release.

1. Create a new report.
2. Drag a Table to the details section.
3. Drag a Panel to a cell of the table

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:

                                    // 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);

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.

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!
