Recently we have noticed that we're having this error on our Live site "The source of the report definition has not been specified." but working on local.

Were still using file version 9.2.15.1105 for both Telerik.Reporting.dll and Telerik.ReportViewer.WebForms.dll.

No code changes or whatsoever.

Any ideas why this happen?

Hi all, I can preview my report in Telerik Report Designer tool, but when I integrate and run the MVC project in Visual Studio, it says "no page to display"... There are no error messages.

When I start the telerik report designer I get this error message:

Clicking ok opens the designer but in the main screen I see:

Telerik.Reporting.Xml.XmlSerializerExcepion: An error has occurred during xml serialization. The xml serializer cannot resolve type with name: Report
   at Telerik.Reporting.Xml.ObjectXmlReader.ReadXmlElement(String name)
   at Telerik.Reporting.Xml.ObjectXmlReader.Deserialize()
   at Telerik.ReportDesigner.Packages.ReportDesigner.Serialization.ReportDesignerLoader.ReadReport()
   at Telerik.ReportDesigner.Packages.ReportDesigner.Serialization.ReportDesignerLoader.PerformLoad(IDesignerSerializationManager serializationManager)

I don't think this error is related with a particular report because it shows every time I open the software.

I used the designer just few days ago and worked perfectly, what can I do? Thanks

hi,

I have a question about Line chart. When all the data values are zero, the line is drawing at the axis line. I would like to adjust the axis line to less than zero automatically for this case. I have attached the existing and expected screenshots. 

How to set the Y axis scale minimum value to less than zero when all the data value are zero. 

Thanks in advance

Hi

I'm developing an WPF app that imports trdx file, serializes to a report object, set an ObjectDataSource and generate (using RenderReport method) to pptx file.

The trdx file contains a subreport with the same DataSource but different DataMember. The DataMember of the subreport get an input from the a report parameter (=Parameters.Param1.Value). The subreport parameter filled by the main report (Param1 =Fields.Id).

For example, for each order in the report, the subreport get its ID as parameter and returns all its order details.

In the generated report (pptx) I see all the reports data but the subreport data is empty. How should I set the DataSource, DataMember and Paramerters of the subreport correctly?

Thanks

Michal

Recently I've had to upgrade reports in one of my projects to a newer version so I could install the Plugins for VS2019. I have a Devcraft Ultimate develop license and installed the _DEV package as mentioned in this article.

This article states 

"Developer licenses come with modified DLLs which work without license keys"

I uninstalled the previous version completely prior to installation, upgraded my Reports to the latest version via the wizard, and the binaries in my project were updated to point to the Telerik install directory as expected. When I run the application locally I can execute the reports without seeing a watermark however if I publish the project for deployment and deploy it to IIS on my client's server all my Reports get the watermark below.

So my question is, where are the actual modified DLL's that are mentioned, all I can see are the DLL's in the install directory and those targetting specific versions.

C:\Program Files (x86)\Progress\Telerik Reporting R2 2021\Bin

I have copied the exact DLL from the build running locally on my machine and still have this problem.

Hi,

I'm trying to pass a parameter value to the sql query like described in the KB article. Sample:

SELECT * FROM Person.Contact WHERE FirstName = @FirstName
This works fine, but if I try with a multi valued parameter, the query gives no results:
SELECT * FROM Person.Contact WHERE FirstName IN (@FirstName)
Any ideas? Thanks in advance.
