Hi there,

I have deployed a Telerik Report (v9.1.15.731) on a machine, and the report itself works great. But when I try to “Export” the report, or click the "Print" icon on it, after the “Save As” window appears and I save, the file doesn't get saved.

It eventually does get saved, but once in every 10-15 tries. It is random. And this issue occurs only in reporting.

I have checked the EventViewer Log and found that the following exception appeared every time this issue was faced. Here is the full log:

Would really appreciate any help, suggestions or ideas to find a fix for this issue.

Thank You!

Currently doing an evaluation of Telerik reporting for use in an ASP.NET development.

Really struggling to see how to access the subreport data from the main report. All I want to do is display some totals from the subreports onto the main report. Really easy in SSRS or even Access, can't see a straightforward way in Telerik. Please help.

I have .trdp report designed in the Telerik Report Designer and displayed with html5 report viewer with REST service.

Initially the report is loading only the group headers and when you expand one the whole report is reloading to get the rows in the group (same for collapsing).

Is it possible the report to load all the data at start, not only group headers, and the expand/collapse to only show/hide the rows html?

I am using the Label Wizard and trying to do a 3 column label report (Avery 8160).

I can only get the data to show in the first column, how do i add it to the 2nd and 3rd columns?

Hello

We have .trdx reports that have text boxes set to Roboto font.  In preview and when I run our application locally, it renders correctly the roboto font.  When I run a report in our QA (and other) environments, most of the text boxes randomly are rendered as MS Sans Serif font.

I tried several things to get all text boxes Roboto,including setting the font in containing elements and copying the style from elements that are correct and pasting them into ones that are incorrect (in the Report Designer).  I have also tried deleting the texts boxes that get rendered incorrect and copying ones that are correct and changing the text.  This has the effect of shifting which text box is correct and which isn't.  Like musical chairs.

Exploring the page source of the rendered html, it appears guid classes (names starting with "s") get set for each text box, some of them have roboto font, some MS Sans Serif.  It appears totally random.

Any ideas?

Thanks
Ian

I have two problems one being that no matter what i set the report format of a date to be it appears to be ignore when i have setup the propertyes correctly its still displaying the long date, as you can see there is screen shot their.

Also how do i pass parameters in the code behind in the html 5 verison in the web form version I would have just done the following.

I have grouped my data in two levels and i need to display the row count of second group as a new column.

I appreciate for any help.

I'm looking for an experienced person who can create some reports that are output to XLS using the Report Server.

In the required report, one tab will have raw data which is the easy part, the other tab will have preset filtering and functions already created in a template that will link the required to raw data.

The report will need to work on demand or scheduled.

If this is not the right place to ask, could you direct me to where to post.

Thanks in advance.
