I want a report like this, How much sales, for each city (vertical) in each season (horizontal) :

Cirty1                     City2                   City3
      Spring                  Spring                 Spring
      day1   1000          day1    2000        day1   3000
      day2   1100          day2    2100        day2   3100
                  ...                        ...                         ...

      Summer               Summer              Spring

Hello

I have a working HTML5 report viewer on my local pc running with VS 2013 dev. webserver.
From this project I copied the necessary files to our web application development server running windows server 2008 and IIS 7.
I copied the necessary DLLs as listed in the How-To, made the web.config entries (binding redirects / handlers) and the global.asax entry, added the report controller to the website's App_Code directory (not precompiled web application), copied the html, css and js files and so on.
The Newtonsoft.JSON.dll seems to be not in the GAC. I copied it too from my working local project.

When I now open the viewer, I see the frame and as soon as it "loads data" It shows 404 - not found where the report should appear:

Module: IIS Web Core
Notification: MapRequestHandler
Handler: StaticFile (is this correct?)
Error code. 0x80070002
Requested URL: http://.....ch:80/api/reports/clients

When I open .../api/reports/formats it shows the same error message. Seems that the handler is not catching the request?
I've also restarted the website and the app. pool several times and tried changing targetFramework to 4.5 but it didn't change anything.
Of course I have some third party handlers but I put the report viewer in a subdirectory with an own web.config where I remove those handlers again without success.

I don't know what to try further but I think I didn't make a mistake by myself. All necessary content from my local project should be on the server as well.

thanks for any help getting this nasty report viewer finally to work - hopefully on the production server too some time!

regards

Does anyone know if its possible to use Json.NET's JObject as a source for graphs? I need to bind a dynamically typed objects in runtime.

In C#, I'm doing this as a POC:

 

var d = new { Missing = 60D, Flagged = 10D, Valid = 30D };        

var s = JsonConvert.SerializeObject(d);        

var j = JsonConvert.DeserializeObject(s);

var ds = new ObjectDataSource();             

ds.DataSource = data;             

var report = new Report1();             

report.MyPieGraph.DataSource = ds;

 

The report renders the graph, but only the legend, not the actual pie graph.

Hi,

I have a text box in a group section and the value is Avg(fields.fieldsName), it works fine if at least one record in detail section in the group has not null value on this column, however, I have a group, none of its records has value on this field, and the textbox in the grouping section through the exception:

#ERROR# Exception has been thrown by the target of an invocation.

is there any alternative I could fix the problem? 

Thanks

I've been beating my head against the wall over this all day and I'm completely puzzled.

 

I'm feeding a pie chart a very simple data source which consists of two columns:  "Category" (string) and "Amount" (double)

If I sort by Fields.Category, it properly sorts the results alphabetically by category.  If I sort by Fields.Amount, my pie chart entirely disappears.. no pie chart whatsoever.

The data I'm passing in is in the form of a DataTable bound to an ObjectDataSource

Any clue what might be happening here?  Is there something else I need to change as well?

We are currently using Oracle.ManagedDataAccess (https://www.nuget.org/packages/Oracle.ManagedDataAccess/) for our application to connect to oracle.

 

However, we have integrated Telerik Reporting in our WPF application, and we're using System.Data.OracleClient for that. 

 

Now though, we have run into a problem where some of our client computers does not have System.Data.OracleClient installed, and installing this is not an option. Because we have bundled Oracle.ManagedDataAccess with our application, we hope to use this provider for telerik as well. 

 

I changed the connection string manager to use Oracle.ManagedDataAccess.Client as a provider, however this causes an error message to be displayed in the report viewer, saying that the provider could not be found. 

 

So, the question; Is it possible to use Oracle.ManagedDataAccess for telerik reporting, and if so; how can I configure this to work correctly?

please help me to come out of this.

Hi,

I could not find a pointer on how to migrate to ReportSource.Parameters for Parameters with predefined values. In my WinForms application I use ReportParameter.AvailableValues. I found that Report.Parameters class has AvailableValues but not ReportSource.Parameters. Somehow I can't make the connection between the parameters defined in the report source and the definition of parameters during processing.

Is there an example for migrating existing code that uses IReportDocument.Parameters with AvailableValues.

Regards

Erwin
