I have viewed the forum for previous messages relating to this error, but my issue is not resolved.
When I click my "Search" button, I am supposed to display data in a Telerik Reportview control. However, I get the message "The source of the report definition has not been specified."  

In my Telerik.Reporting.Report page, I have a Telerik.Reporting.SQLDataSource control that has a valid connection string value, along with a valid parameters value and a SelectCommand value to a stored procedure.

In the Telerik.Reporting.Report page, the properties window displays a valid value for the DataSource along with ReportParameters. 

So I am providing an accurate report source. I can see the data perfectly fine in Preview and HTML mode in the reportviewer design time. The issue is when I run my asp.net application, I cannot see the data displayed on the aspx page.


What else could be causing the data to not display?

Good Evenign

i am not using MVVM parttern, i looked for examples here on our site and could not find just a simple way to refresh a Reportviewer in Silverlight. The Scenirio is simple. i have a listbox outside the Report, and when the SelectedChanged even is fire, i want to refresh the report, So i tried to call the Asnyc of the "reportViewer1_RenderBegin" Event , but nothing is happenig. my renderbegin is initializing the report parameters. So i want to refresh a report.

THanks

Hi,

Using Visual Studio 2008 with Reporting.

I just updated from Q1 2013 to Q3 and I don't know how to upgrade my references. I have seen a few pages that mention using the Reporting Upgrade wizard on the Telerik menu, but I do not have that.

Am I missing something? (See attachment images)

Thanks!

I am having an issue when I have multiple page reports. The first 2 pages show at the correct height but when I hit the third page the height is about 150px with a scrollbar. I only see the issue in IE10. Also if I go into compatibility mode I see no pages.

There is a link to the report

Hello All. I have a problem I am not sure how to fix. I developed a bunch of reports using Q3 2011 and my boss took it upon himself to move my development projects to a new pc and reformatted the old one. The problem I face now is that none of my reports will open and I can not find the original install for Q3 2011 to reinstall in hopes of fixing the issue.

I get several errors telling me that a slew of parameters with name 'xxx' already exist, where 'xxx' is the name of one of my parameters. How can I fix this issue??

Hello,

We have a problem with a report when exporting to PDF. For some reason a chart is split over 2 pages when exporting. The problem only occurs at the production server. If we export the report locally there aren't any problems. 

I attached some screenshots with the problem. 

Specifications
Iss (v7.5.6) is on both systems the same.
We used a copy of the productiondatabase so that can't be the problem.
Windows 7 (local) vs Windows Server 2008 (production)

I am going mad with this:
I have made a report in a class library and then referenced the DLL in my website project.
Added the viewer and the code in the page behind:
Locally on my machine is working fine. No problems of any type. Beautiful.
Then I change the string in the web.config from the local database :

to the production database:

And when I finally try to run the report on the production server I get the following message (also in the attached pic):

"""An error has occurred while processing Report 'IndustryRep': Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."""

What is very strange is that I have other additional 4 reports on the same website out of the same class library that works without problems.
What could be wrong on this particular report?
Some help will be appreciated.
Thanks,
Felice

Hi,
I know this question has been asked in the past but may be that with time and new added features there is something new on this subject.
I have a simple report with Customers by countries and I would like to give the user the possibility to choose a specific country to be rendered as report.

Is there a way to add a filter with preselected values on the report that can be used at runtime by the user?
Something like a drop down list.

Thanks,
Felice

HI

I have a class

public class LeaveDaysData
    {
        public KozpontiFelhasznaloProfilItem User {get; set;}
        public List<DateTime> Datum {get; set;}

        public LeaveDaysData()
        {
            Datum = new List<DateTime>();
        }
    }

List<LeaveDaysData> is the the datasource of my List in report. In report I need to display the first and the last element of the nested Datum List, but if I put one more List and bound datasource to the Datum list it displays first elements date as the first and last element, and it repeats as much elements are int he list.

thnx
