Some reports do not display in list when selecting ReportSource Object Instance and browsing for report document

[Karl Wilkens]

Hi, we are using Q3 2012 Reporting, and have a class library that contains all our reports. We are creating sub reports and in our main report, in the sub-report properties tab, click ReportSource, and then select Object Instance, and finally, select document from the drop down. The resulting list only contains some, but not all of the reports in our report class library. Why is this so?

Hi Karl,

Check the following:

• If the needed references to the report libraries are added;
• If all reports are successfully built;
• If all reports use the same Telerik Reporting version, if you have recently upgraded your projects.

If none of these is the issue, please elaborate, so we can help you.

All the best,
Stef

Hello Riyadh,

Please elaborate on your issue:

• Have you tested the suggestions from my previous post?
• What is the type of the targeted reports?An Object instance can be only a report built with Visual Studio. XML report definitions can be linked by URI.

If you need further help, shows us the solution structure and let us know the version used to build both master and details reports.

but the problem now is how to can assign the current row of master with sub report (details)
I using Object Data Source  to assign the report with  the names of fields 
and assign with form and select data from data base with this way 
  var v = Data.RptPerson.Select();
                Report.RptPerson r = new Report.RptPerson();
                r.DataSource = v;
                reportViewer1.ReportSource = r;
                reportViewer1.RefreshReport();

  make the solve is more difficult can you help 
I don't know if all things are clear I wish that

Hello Riyadh,

The described scenario is master-details report illustrated in the How to: Create a Master-Detail Report Using a SubReport Item help article:

1. There is a master report with its own data source and a sub report with other data source. Both reports data is related by some field(column);
2. In the sub report there is a report parameter by which its data is filtered;
3. In the master report Detail section is placed a SubReport item, which ReportSource is set to the sub report. Notice at   Configure the SubReport in the tutorial we set the SubReport.ReportSource and link the sub report parameter to get value from a field in the master report.

The result will be for each rendered master report's Detail section to be displayed a details report with filtered data based on the current master report's data.

You can check the Invoice demo illustrating the Master-Details scenario in our local example, located by default under C:\Program Files (x86)\Telerik\Reporting Q3 2013\Examples\CSharp\ReportLibrary\Invoice.

Other approach is to leave both master and details reports without data and use the master report's NeedDataSource and the SubReport.NeedDataSource(or the details report's NeedDataSource) events to set the data. For more details take a look at Using the NeedDataSource event to connect data help article.

If you need further help, please open a support ticket and send us a sample project illustrating your scenario.
