SubReport in ActiveReport

The description on the internet is incomplete and the sample is too simple. Here we will record the correct practices of SubReport:

1. Create one MainRep and one SubRep (××× both are bound to display ×××)

2. Place a SubReport control in MainRep, and then display the SubReport in the code.

In the MainRep_ReportStart event, the initial settings for SubReport

This. subReport2.Report = new NewActiveReport1 ();

In the XXXX_Format event, data processing and display ----- for example:

SubReport. Report. DataSource = DS;
SubReport. Report. DataMember = "TableName ";

In this way, it can be displayed.
