Hi,

I'm trying to integrate reporting rest service to Winforms Report Viewer

I'm getting the below error during report rendering

An exception has occurred while processing 'table1' item:

System.InvalidOperationException: The data provider of type 'Telerik.Reporting.Processing.WebServiceDataSource.WebServiceDataProvider, Telerik.Reporting.WebServiceDataSource, Version=13.0.19.116, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' defined for data sources of type 'Telerik.Reporting.WebServiceDataSource' cannot be resolved. Are you missing an assembly reference?
   at Telerik.Reporting.Processing.Data.DataProviderFactory.ResolveDataProviderType(Object component, Type baseType, IDataProviderContext dataProviderContext)
   at Telerik.Reporting.Processing.Data.DataProviderFactory.GetDataProviderTypeCached(IDataSource component, IDataProviderContext dataProviderContext)

   at Telerik.Reporting.Processing.ReportItemBase.ProcessElement()
   at Telerik.Reporting.Processing.DataItem.ProcessElement()
   at Telerik.Reporting.Processing.ProcessingElement.Process(IDataMember dataContext)

 

Upon looking into this further i was unable to find the namespace Telerik.Reporting.Processing.WebServiceDataSource.WebServiceDataProvider

Some help would be appreciated

            }
            catch (Exception ex)
            {

            }
            catch (Exception ex)
            {
                return null;
            }
        }

        protected override HttpStatusCode SendMailMessage(MailMessage mailMessage)

Hi, 

I use html reporting and I need to have a filter like this in photo attached, where I can filter through a text. How can I do this from designer?

 

Best regards

 

 

I have a report viewer in reportviewer.aspx. After I generated the report, I chose Excel format and click Export. I found that in backend, when I press the export button, it goes to load the data again and it make export take 20 minutes or more. I am doubting whether the export is just dumping the already generated report content or will load the functions and do the calculation once again. How can I avoid the export to do the calculation again but just dumping the already generated report?

What do mean with CALs in Telerik Report Server licence?

 

Is it number of application that will use this server?

or number of actual users they have permission to access reports through this server?

 

for example, If I have an angular application and an asp.net application.

These two applications will use Telerik Report Server

In this case, do I have two CALs?

or

If I have 10 users access reports through these tow applications. so I have 10 CALs?

 

Which is right?

Number of applications?

or

Number of actual users regardless of number of applications?

In my report I have two datasource.  In this case the first is the data (detail) and the second is another query that brings a single line that I need to show in the header.  Is there any way to make a textbox display this information?

I have an application that has an angular 6 client with telerik reporting viewer,and C# api server.
I have created a report with the report designer. the report has 2 dateTime parameters defined like in the snapshot: 
Now, I use it in the web service data source like on the other  snapshot

So far so good.
I update the parameters value from my clients this way:
let rs =

{

report: this.reportName,

authenticationToken: token,

parametersAreaVisible: true,

parameters: {

     networkItemsKeys: JSON.stringify(parameters.tags),

     token: token, userName:this.userName,

     toDate: parameters.toDate,

     fromDate: parameters.fromDate } }

      as unknown as JSON;

      this.reportSource = rs; this.reportViewer.setReportSource(rs);

    parameters.toDate is DateTime property. 
I can see that the date parameters are updated fine when looking at a textbox defined this way:
Report Period: {Parameters.fromDate.Value.toShortDateString()}-{Parameters.toDate.Value.toShortDateString()}
The problem is that when I check the value that is received in my web api has month and days switched so if the day is greater than 12 the parameter value is 1/1/0001. I have tried all sorts of datepipe format changes, with no success.
The problem is solved when I use the toDate and fromDate as string parameters, but is seems like a stupid solution, and that way I can't use the date type abilities like .toShortDateString() in the text box. Any ideas?

I am currently trying to add the HTML5 ReportViewer to a .ascx page, which will then be toggled on a .aspx page as to whether be displayed or not.

I'm using an asp:Placeholder on the .aspx page and adding the User Control to it on a button click. The user control renders the text I have on the page, but looking at the Chrome console, I just see the attached blank ReportViewer.

I've added the Assembly Registers to both the .aspx and .ascx page along with the required Kendo scripts/ stylesheets.

I'm not sure what I'm missing, is this even possible to do?

 

I am running a Build on my company's Team Foundation Service for a Class Project that contains Telerik reports. The Class project is added to our websites and the reports are used for various things. When I build in Visual Studio, it works fine and syncs fine with TFS


After I sync into TFS and try to run a build on the Class project, I keep getting the following error for each Telerik Report:

C:\a\src\iLEVELClass\iLEVELClass\Reports\ReportEmployee.resx (123): Invalid Resx file. Type Telerik.Reporting.Drawing.Unit, Telerik.Reporting, Version=8.0.14.507, Culture=neutral, PublicKeyToken=a9d7983dfcc261be in the data at line 121, position 4 cannot be located. Line 123, position 5.

Any ideas on how to get a successful build?

I am trying to get the MVC Report Viewer working with my project.

I am seeing the following errors in the browser:

http://localhost:3032/api/reports/resources/js/telerikReportViewer net::ERR_ABORTED 404 (Not Found)

Uncaught TypeError: jQuery(...).telerik_ReportViewer is not a function
    at HTMLDocument.<anonymous> (SalesReportViewer:37)
    at l (jquery-3.3.1.min.js:2)
    at c (jquery-3.3.1.min.js:2)

I can confirm that this URL works:  http://localhost:3032/api/reports

[{"name":"PDF","localizedName":"Acrobat (PDF) file"},{"name":"CSV","localizedName":"CSV (comma delimited)"},{"name":"XLS","localizedName":"Excel 97-2003"},{"name":"RTF","localizedName":"Rich Text Format"},{"name":"IMAGE","localizedName":"TIFF file"},{"name":"MHTML","localizedName":"Web Archive"},{"name":"XPS","localizedName":"XPS Document"}]

But this does not: http://localhost:3032/api/reports/formats

The ReportViewer folder in my project is empty should it be populated?

The Example Telerik Reporting project works and the MVC ReportViewer shows as expected.    However, I can't figure out what might be missing from my project.   I reviewed a number of your instruction pages but have not found the proper solution.

Any guidance you can provide would be great.   Thanks
