Master-Detail reports with Entity Datasource

[Ibrahim Imam]

i want to create a report that shows a hierachy of several entities.
i read in the manuals and samples about master and detail reports using sql as datasource and parameters in the subreports for filtering the correct rows but i want to create the report with the data from already existing entities.

Example of Data Structure:

CompanyData:
string companyName;
string companyAddress;
List<DepartementData> departements;

DepartementData:
string departementName;
List<PersonData> persons;

PersonData:
string Name;
string Birthday;

so this would be a structure with one master report and a subreport that has a supreport itself.
i plan to pass the companyData as datasource to the master report but how can i pass the data on to the subreports?

Thanks for Help

Hi Ibrahim,

We have attached a simple project that demonstrates how to nest the report and provide data to it.
The main report is bound to the Departments business object. For every subreport we use the NeedDataSource event of the SubReport to set the DataSource of the subreport.

We hope this will help, but do not hesitate to contact us again if you have any other questions.
