export to pdf

[Zeeshan]

I am currently trying to use export to pdf. It takes forever. Can seem to comprehend why it takes longer. Any hints on what i can look at to identify bottle necks. Secondly i want to know a little bit more about how u are generating pdf files specially the large files which could 10 to 12 mb. In the past i was using aspose to convert to pdf and it brought our server down cuz of high memory usage. Please explain.
You guys have a nice suite of products. I am so glad i finally convinced my company to move from infragistics.(nightmare!)

Hello Zeeshan,

Thank you for the kind words. It is pleasure for us to hear that you like our controls.

The most common reason that causes the report rendering to hang (and that we're aware of) is when you have a subreport and the data source of this report is empty - i.e., returns no rows. To work around this issue simply add an empty report header with zero height (ex. Unit.Inch(0)).

Please note that if you missed to attach a data source to the subreport you can experience similar problems too.

Currently we have no known issues with the generation of larger PDF documents. The size of the output files depends on many criteria, the most important being:

• the fonts you're using (to ensure that the created pdf can be viewed on every PC we embed all fonts. However, some fonts that support many languages are too large);
• images - if you are using larger images this will enlarge the output file;
• the compression process of the PDF.

As you can see there are several directions to improve the PDF generation and we're working on them. If you experience any problems with this functionality don't hesitate to contact us.

pls provide a different workaround. this work around does not work for me when the sub report data is empty. When i set the report header height in the designer 0, it get an exception like this.

Hi Zeeshan,

It seems that Html rendering does not allow zero height for the report sections. To workaround this issue try to set the height of the report header to a small value greater than 0, for example 1pt.

We are sorry for the inconvenience. The issue is logged and will be fixed for the next release. Your points have been updated for the report.
 

Kind regards,

thks for the quick reply that actually works for me now i have another problem and that is when it exports to pdf i get an extra padding in the middle. I am trying to figure out what property to turn off so i dont get an extra padding. it seems to appear fine when viewing in the browser. Pls tell me what properties i need to look into. i have a report and sub report.
You have been a great help so far.

Thanks

[Chavdar]

Hello Raj,

There can be different reasons for the padding. In order to help you it will be best if you can send us the main and sub report definitions so that we can investigate the issue. A screenshot which points out where is the problem will also be helpful. You can send us the files through the support ticketing system.

Thanks in advance.

Hi,
I created Report , and Exported it to PDF, my report size is too bi, one page of PDF report is of 15 MB,

I sent this problem to support , support told me to use this

<configSections>

<section name="Telerik.Reporting" type="Telerik.Reporting.Processing.Config.ReportingConfigurationSection, Telerik.Reporting.Processing, Version=3.2.9.1104, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" allowLocation="true" allowDefinition="Everywhere" />

</configSections>

<Telerik.Reporting>

    <Extensions>

      <Render>

        <Extension name="PDF">

          <Parameters>

            <Parameter name="FontEmbedding" value="None" />

          </Parameters>

        </Extension>

      </Render>

    </Extensions>

  </Telerik.Reporting>

If I use this in configuration file then I got again exception "Telerik.Reporting.Processing" can not found.

What to do with this.
with regards
Chandrapal Singh

Hello chandrapal,

We've noticed that you're using Telerik Reporting Q3 2009 and in that version there is no longer a Telerik.Reporting.Processing.dll assembly - it is not part of the Telerik.Reporting.dll. So the Telerik Reporting config section should be changed to reflect that change accordingly:

<section name="Telerik.Reporting" type="Telerik.Reporting.Processing.Config.ReportingConfigurationSection, Telerik.Reporting, Version=3.2.9.1104, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" allowLocation="true" allowDefinition="Everywhere" />

That is the information I've pointed you to in the KB article: The size of the exported PDF file is big.

All the best,
Steve

Hi Prasad,

Upgrade to the latest internal build available for download in your account and let us know if the issues persists.

[Prasad]

steve,

Is it the  problem with data, because report is generated for other search criterion. After getting the error when i export it to pdf i am able to download the file .

Is the problem in Telerik or Data?

[Prasad]

Raj,
Please let me know how did you overcome this.
I am also getting the same error which is yet to fixed.

[Steve]

Hello Prasad,

We see that you have downloaded the Q3 2011 SP1 version, can you confirm whether the problem still occurs or not? If the latter, please open a support ticket and attach a sample runnable project which we can look into.

All the best,
Steve
the Telerik team

[Prasad]

Steve,

My problem has been resolved.

I am using telerik reportin 3.1 version.  In that i have used a hmlTextbox, it has an expression "Zurich" this expression led to get the "Index out of range exception" in report viewer. Here the root cause is "Zurich" is a font name.However i converted this to Upper case "ZURICH"  so that i am not getting the exception.

I hope this was fixed in latter versions of telerik .


Long back we also get this exception for sign "&".




Thanks Telerik support Team for Quick response towards actual root cause.
