Can we change the layout of the HTML 5 viewer . Like Parameter at the top of the report instead On right side.

Also I want to display a dropdown box instead of default Listbox for report parameter.

Please let me know if it is possible

I have a master report with two subreports. The dimensions of each areabout a A4 page. I use two parameters to hide the subreports. So normaly the report should be two pages if both parameters are activated and one page if only one parameter is activated.

But I always got two pages, page one empty if only subreport two is activated and page two empty if only parameter one is activated.

I am using the following bindung für the two subreports

Subreport 1: 

• Expression: = Parameters.param1.Value
• Path: Visible

Subreport 2:

• Expression: = Parameters.param1.Value

• Path: Visible

What can I do that the subreports will not use any space when visible=false? If I have a look at the 'HTML Redering' the space is empyt, but if I have a look at the print preview or do an export the space ist used.

The problem is that i have to create a Master/SubReport using 50 subreports where the user can select the desired subreports.

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.

Is it possible to have a legend based on  series data points?

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:

                                    PDFToImageParameters fileParams = new PDFToImageParameters()
                                    {
                                        FilePath = imagePath,
                                        FileResourceName = "",

                                    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.
