Hi,

When I run my report on a 3G connection it crashes.  I've tested with a very slow WIFI connection but that is OK so it isn't a timeout issue.  Any pointers?

Error is below:

Hello,
I am currently working on a telerik report. I need to assign an image to a picture box depending on the value of a field that I retrieves my datasource .
I want to use an expression but I do not know how to send the image.

My two images are stored in the resources of my project.

Should I create a function that returns me the right image or art that I can retrieve the image directly in the expression.

kind regards ,

Julien

I am using the Stanalone Report Designer Version 7.0.13.426 (Q1 2013 SP1). We want to change the behaviour of the footer rendering when exporting to excel. Because we are using fields to calculate function in the footer of the template.
I know that we have to set 'UseNativePageFooter' to 'false'. But I simply can't find 'UseNativePageFooter', not in the 'Telerik.ReportDesigner.exe.config', not in the .trdx file of the template and not in the gui of the Report Designer. 
Is this function not available for the Standalone Report Designer, or did I overlook it?
If it is not available, what other option do I have to achieve the expected output?

Hi

I would like to show lines connecting child nodes to parent nodes on report. How can I do that.
Or can I change background color of level 2 and its child nodes on report.
Thanks

I'm getting an ArguementException when setting the viewer's ReportSource to the instanceReportSource.
It was working fine in 2013 Q1, but is broken in 2014 Q3.
Thanks

I am trying to publish my first Telerik Report to the web. I can display the report when I run it in my development environment. However, when I publish it, I get the following error. (The first error I got told me to insert this     

<add verb="*" path="Telerik.ReportViewer.axd" type = "Telerik.ReportViewer.WebForms.HttpHandler, Telerik.ReportViewer.WebForms, Version=3.2.9.1211, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" />
Line 48: </httpHandlers>
Line 49: <httpModules> ,

and then it says it cant find it.) If I delete it, it tells me to insert it. If I insert it, it says it cant find it. Any ideas?

Hi,
Following an test upgrade to .Net 4.5.1 I have had a problem with reporting.  Webpages that used to work now don't workl properly.

I have reduced the page down to a small sample.  The problem is that when a filter button is pressed the ajax call is done with the reportviewer flashing a loading panel then it shows the "The source of the report definition has not been specified." message.  Looking at the codebehind the report is generated OK and is in fact applied to the report viewer.  As mentioned this all works fine with .Net 3.5.

To further test I disable Ajax on the AjaxManager and then following the post back the control works as it should so this is definitly an Ajax issue of some sort.  I am posting the code below.

It is worth noting that I have tried this on two distinct website solutions that I have and exactly the same issue appears.  

Many thanks for any help.

Regards

Jon
