Hello,

See the attached files. When i set ColumnHeaderPrintOnEveryPage = true, it prints the header on every page when i export to PDF. Why is it that there is not the same space between the page header and the table header?

Show Cover Page only while Exporting

Is there a way of adding a cover page in a Telerik Report only whilst exporting using the Telerik Reporting Web Services? I assume if the answer is no, the only option is to manually handle exports?

Another option, would it be possible to hide pages in the Report Viewer (e.g. the first/cover page) instead?

Conditional formatting with blank string

I want to make a Group Header invisible when the group field is blank. In the conditional formatting tool, I selected the correct field, the expression is "=" and I select <blank> for the value in the dropdown list. I then unchecked the Layout/Visible field. When the report runs though, the header continues to show even when the field is blank (e.g. =''). I've tested it with a known value and it does make the header invisible so it seems that it's not detecting the blank value correctly. What am I doing wrong here?

HTML 5 Report Viewer Destroy

Hello
I would like to use Report Viewer on SPA application, however based on kendo experience (knowing that I should destroy all kendo widgets, before page change). I wonder if it is possible to d the same with Report Viewer. I couldn't find any destroy method in API.

So is possible to destroy, or is it safe to just leave it and initialize multiple times? Or should I choose 3rd way?

Kind Regards
Marcin

Arithmetic operation resulted in an overflow

Hi,

We are using the Telerik Reporting to generate reports within our web application. Details are below. We are currently running the application on Windows Server 2008 R2 (IIS 7.5) and are looking to move the application to Windows Server 2012 (IIS 8). When we generate the report, we get the below.NET exception in the Report window. (I also attached the error in a JPG)

We verified that this is not a SQL exception from our database procedure call. We are even able to Export the report to a PDF and the PDF looks correct (as we would expect the report to display on screen). We have other Telerik controls within the application (mainly the Scheduler control) and that is working in Server 2012/IIS 8 without an issue.

Is this a known issue when using IIS 8? I checked the forums and have not seen another report of the same issue. Let me know if you need any further information. Thanks for your time and help.

Application:
- .NET 2.0
- Telerik.Reporting.dll version : 3.2.9.1211

HTML5 ReportViewer set default page number

Can there be an option to set the default page number for the HTML5 Report Viewer? (Related to my cover page question) I can get around having the cover page always been part of the report if in the Report Viewer, it shows page 2 by default (instead of Page 1).

For now, I've changed the telerikReportViewer javascript file, but it would be good if this is possible through the API or an option etc

Current Code (Line 1298 of telerikReportviewer-8.1.14.804.js):

if (!navigateToPageOnDocReady) navigateToPageOnDocReady = 1;

Changed to:

if (!navigateToPageOnDocReady) navigateToPageOnDocReady = 2;

Since all reports i'm viewing have a cover page, I can make this change...otherwise include the original JS, or set it to a variable/function/resolver etc.

I've tried using the command goToPage (http://www.telerik.com/help/reporting/html5-report-viewer-reportviewer-properties-commands.html) but it wasn't working, probably because the page wasn't ready loaded yet?

Any help, much appreciated!

Open type fonts

Hi

I came across this KB article.
http://www.telerik.com/support/kb/reporting/details/font-is-missing-in-report-designers

Is there any update? Can we use OTF fonts or still we need to convert them into True type and use them.

Thanks in advance
