I have a user function that returns an object with a lot of calculated fields that are expensive to call each time. Is there a way to call the function one time and save the results so that it doesn't get called multiple times as I display the fields on the report?

There are at least 10 individual text fields that are displayed on the report that all come from the user function.

Thanks.

Hello,

I am using Telerik Standalone reports (.trdx) reports of version Q2 2014. I am facing an issue with HTML preview of report being used in an MVC ..net  project. I am using mostly table object to render data but this issue occurs on any type of control i place in report.

Both the issue picture and required result pic are attached with the thread. 

I want to programmatically export a report book, however this command fails when I try to compile with the error:

Error 6 Argument 2: cannot convert from 'Telerik.Reporting.ReportCollection' to 'Telerik.Reporting.ReportSource'

Telerik.Reporting.Processing.RenderingResult ReportOutput;

ReportOutput = reportProcessor.RenderReport("xls", RB,

null);

I've seen a ReportBook passed to the reportProcessor in other online examples, so I'm not sure why it's failing. I'm running 2012 Q2.

Hi!

 I am currently trying to design a crosstab report with the following basic layout:

Row 1:   |Header1 | Header 2 | Header 3| Header 4|

Row 2:   |Group 1 |                 |                |                |

Row 3:   |              |Group2     |                |                |

Row 4:   |              |                 |Group 3   |                |

Row 5:   |              |                 |                |Group 4   |

The first group is visible, the rest is collapsed at the beginning.

To make the whole table visually a bit more attractive I want to use empty lines to create blocks that make the table look like in the first attached image file.

I achieved this by adding empty rows between Row 1 & 2, and Row 2 & 3. This however only works of course if no other group is expanded. If I e.g. expand Group 2, the result would look like in the second attached file.

To preserve this visual blocks my idea was to insert such an empty row after each group, and change it's visibility depending on the visibility/expension-state of the group above.

 I managed this by giving the empty rows a StyleName, and in the DataBound-event of the according textbox that represents displayed groupdata I iterate through all textboxes with that Stylename and change their visibility accordingly.

 There is however one simple problem: all event that I found will only fire when I expand a group (ItemDataBound, ItemDataBinding). When I collapse a group no event seems to be fired at all.

Are there any events that could help me in this case? Or would there be a databinding alternative?

Hi,

I want to achieve functionality of creating report definition file (trdx) programmatically and then display into HTML5 page.

For this, I was going through below links-
http://docs.telerik.com/reporting/programmatic-creating-report

http://docs.telerik.com/reporting/report-sources-viewers

However, I couldn't achieve require functionality.

Could you please share step by step guide to achieve this functionality?

Hi,

I want a visible gap between a GroupHeaderSection and the DetailSection. What is the best way to achieve this?

I have set the height of the header and this has the desired effect however I can't use this in my case as the header has a different background color so stretching the header isn't an option.

Many thanks,

Mark.

Hi all,

Our development team are experiencing an issue of getting nullable report parameters from report viewer (HTML 5 + RESTful + TRDX). 

We created reporting module by Q3 2015 of Telerik reporting library and it worked util we upgraded the libraries to the latest version. Below steps shows what we done in our reporting module.

1. Create report definition files (TRDX) by Telerik Report Design Q1 2016. 

2. Generate reports by Telerik Reporting MVC, Restful reporting service and Trdx which is a very standard process and it works for reports which doesn't has any nullable parameters. Issues occurred only on reports that have nullable parameters.

3. If TRDX has any nullable parameters, we will see below errors.

=======================================================================================================================

Failed to load resource: the server responded with a status of 404 (Not Found) - http://localhost:56559/api/ReportServer/clients/092813-a9d7/instances - The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.

=======================================================================================================================

According to Telerik document, this error is expected since we didn't define default values for those nullable parameters. However, after users entered report parameters at report viewer, the program will get parameters from UI by Javascript then it throws an exception like $('#orionReportViewer').data('telerik_ReportViewer') is undefinded. 

 The code of getting report parameters shows as below. It worked at Q3 2015.

========================================================================================================================

 var reportSourceParameters = $('#orionReportViewer').data('telerik_ReportViewer').reportSource().parameters

========================================================================================================================

Can anyone help me to solve this problem? Its very urgent. It seems that getting report parameters by JS not works anymore if trdx has nullable parameters. 

I double checked routing settings, NewtonJson versions and both report designer and reporting libraries are upgraded to Q1 2016. Did I forget to check any thing else? 

Thank you

Alex
