    Hi, I want to do a report that have multiple master-details,

    my environment is Winform , Reporting R1 2017, UI for WinForms R1 2017 SP1,

    what I supposed is like attach file 1.png,

    there have group header to place master data, and a table to show detail data,

    and will print multiple page for multiple master-details data.

    I created data class and also a method that return the datasource (return type is List<RptDataMaster>):

    public class RptDataMaster
        public string WaveNumber{get;set;}
        public string CustomerNumber{get;set;}
        public string OrderNumber {get;set;}
        public List<RptDataDetail> list{get;set;}
        public RptDataMaster()
            this.list=new List<RptDataDetail>();
    public class RptDataDetail
        public string ItemNumber{get;set;}
        public string ItemName{get;set;}
        public int Qty{get;set;}


    but next, I have no idea how to grouping them up at report designer,

    should I add two objectDataSource (bind to RptDataMaster & RptDataDetail) or something?

    Please give me some suggestion, thanks!

    Hello Kiman,

    To show each member of the list collection you need to use a separate data item - How to Databind to Collection Properties.

    A sample report demonstrating the suggested approach is attached.

    I hope this will help.

    Hi Katia,

    Do you have an example like above, buth with an extra collection detail. So, the RptDataDetail class then has its own collection. For example a Collection of RptDataDetailItem.

    In the report this extra collection is another detail level that needs to be displayed. Is this possible?

    Kind regards,
