Nested SubReports ReportSource.DataSource does not exist

[Steffen]

Hi there,

using the standalone report Designer to create trdx report, the often
in C# described method  will not work fpr TRDX based subReports!

an error has occurred while processing subreport 'subreport2':
Bindings rror Property 'DataSource' does not exist.

everbody knows, in C# way, it works like:

this.subReport1.Bindings.Add(new Telerik.Reporting.Binding("ReportSource.DataSource", "=ReportItem.DataObject.Persons"));

but using the Standlone Designer (TRDX file), for the binding, he cannot find DataSource ?
...
        <SubReport Name="subReport2">
          <ReportSource>
            <UriReportSource Uri="ReportLines.trdx">
            </UriReportSource>
          </ReportSource>
          <Bindings>
            <Binding Path="ReportSource.DataSource" Expression="=Fields.Lines" />    ----- .DataSource is not found
          </Bindings>
        </SubReport>
...
thank you for helping
Steffen

Hi Steffen,

With the introduction of the XML report definition the reports can exist not only as CLR types and objects in the memory but as XML markup stored in different ways (file, database, etc.). As we do not want to limit the users to work with only objects or files the need for a unified way for referencing reports in the applications emerged - Report Sources. As you see the naming matches the old ReportSource property of the SubReport item, however the new ReportSource does not have a DataSource property.

You can see how to handle binding of the SubReport with the introduced changes in the following forum thread.
