report.RegisterData(dataSet1, dataSet1.DataSetName);

Hello,

FastReport does not save database items that are not enabled. When you call RegisterData method, all DataSet items are added into the dictionary, but they are all disabled. You have to enable necessary items via the "Report|Choose Report Data..." menu or programmatically. In the latter case, use the following code:

report.GetDataSource("table_name").Enabled = true;

thanks
it means that relations never appeared in the report files

AlexTZ

Relation will be enabled automatically if its datasources (parent and child) are enabled.

hello
I register All Tables of Dataset but no relation enabled in the report,
I have to go to the design mode and define their relations!

AlexTZ

Hello,

How do you register tables? If you call report.RegisterData for each DataTable in your DataSet, it won't register relations. To do this, register entire DataSet:

report.RegisterData(your_DataSet, "ds_name");

In this case, all DataTables and Relations will be registered.

Ok But when I Register DataSet when seeing my report in Design mode
the Relations are not available ,DataTables are not available too but by enableing them they are appeared in design mode but no relation found

AlexTZ

I see. To enable relations (after you have enabled data tables), use the following code:

      foreach (Relation relation in report.Dictionary.Relations)
      {
        relation.Enabled = relation.ParentDataSource != null && relation.ParentDataSource.Enabled &&
          relation.ChildDataSource != null && relation.ChildDataSource.Enabled;
      }
