No Toggle Button within Report Viewer

[Coal]

So the question is simple, though the set-up and and architecture may not be.

The simple point is, I have a report with drill down action using toggle, and the toggle button it produces that I can work with in the preview just fine. However, when I've exported the report and view it within the Report Viewer, the report renders will all the data just fine, but the toggle button is no longer there so that functionality is lost.

I'm using the web form report viewer control, my team is adamant on using this to avoid the external calls the newer version relies on to function. The report is provided by deserializing xml stored within the database. The webform has registered assemblies to the reportviewer.webforms and reporting namespaces.

Hi Coal,

The specifics of the available rendering formats are available here. Note that there are formats like PDF and Excel where the drill-down actions are not included, the result document illustrates the last state of the report (visible and hidden items/sections) displayed in the viewer.

In order to provide you further suggestions, please elaborate in which rendering you are missing the collapse/expand mark of the ToggleVisibilityAction. Screenshots of the issue and details about the used Telerik Reporting version will be helpful.

Thanks Stef,

     Your post got me on the right track. I had the report viewer set to the preview mode by default because one particular report will time out when using the interactive mode so by default it was trying to display the report as it would be printed without the interactive elements.

    I apologize I had previously used another solution with natural pagination that maintained the interactivity.

    This means if I have a rather large data-set that fails to load in interactive mode that I may have to forgo this functionality for that particular report all together? Is there another control that can display large datasets but supports toggle functionality for the drill down if the need arises?

Thanks again.

Hi Coal,

Please elaborate on the timeout occurring with large data sets. If it is related to session timeout, please check the recommended settings in the Report is unavailable or session has expired error message KB article.

The only issue that comes to my mind is that if you use a Table item to display the data, the content in Interactive preview will be rendered on a single page, and browsers have limitations about the number of HTML elements rendered on a single page - Browsers and Limitations. This can be avoided by using Print preview, or adding ToggleVisibilityAction and displaying initially a smaller number of rows which expanded show the rest content in bits, not the whole content at once.
There are also other workarounds like avoiding the Table item or filtering data to smaller sets.

Hi Stef, 

               I am also facing the similar kind of problem, I have 1 Master report inside that 5 sub-reports, In each sub-report i m have 1 TextBox for sub report name and i applied toggle action for that text-box. on toggle it will drill down the report contents which are placed in panels in same sub report. I am keeping by-default all sub-reports expanded . The problem is that first 4 report has small content size where as last 1 is little bit large as compare to others, In Project preview all the reports are showing properly but when i am using it in web application at run-time the last sub-report is not showing fully , some content will cut off. I kept keep togetherfalse for that sub-report still i am facing same problem, Please tell me what is the problem.

Thanks in advance

Hello Pratap,

Please test if exporting the report in PDF produces the expected layout. If yes, check the loaded on the page styles and if there are CSS rules in conflict that may affect the rendered in HTML report in the viewer.

If you need further help, please open a support ticket and send us a demo project that reproduces the problem.

Hi Stef,

            Thanks for your reply, that issue was resolved when I change ReportViewer version from telerikReportViewer-9.0.15.422 to telerikReportViewer-9.1.15.624 . It works fine in IE and Chrome but report is not rendering in Firefox. Still I am using Telerik Reporting Q1 2015  for designing the reports but only for Displaying  I am using ReportViewer from Q2 2015 and facing problem while rendering in Firefox.

Hi Pratap,

The problem in Firefox is a known issue fixed in the latest available internal build v9.1.15.702. It can be downloaded after logging into your Telerik account at telerik.com and navigating to Telerik account - Products & Subscriptions - Latest internal builds. Then select Reporting in the product drop-down and version 9.1.15.624 as official release to which the internal build belongs to.

After installing you will have to run the Upgrade Wizard.
