Access the subreport sub-report implementation table
A: insert a subreport into the detail grid. The reports associated with the subreport are displayed multiple times in the detail grid of the main report. Generally, a subreport must be associated with the data of the primary report. In the subreport table, parameters with the same name as the fields of the primary report are defined, and parameterized query SQL statements are defined. In this way, the data of the primary report can be associated. For more information, see (example template) 1 M. subreport implementation table. grf

Can I directly input or modify data in a table? Just like your common table control, you want to directly enter the basic information and documents in the form for easy IGRRecordset. the Editable attribute specifies whether the record set can be edited during report running. Does this attribute indicate that data can be directly modified? How can this attribute be used?
A: Grid ++ report is a report and does not support table-based editing.
When the IGRRecordset. Editable attribute is true, you can use code to edit the data. For example:
Recoredset. Editable = true
Recordset. edit
Report. Fieldbyname ("Fieldname"). asstring = "zzzz"
Recordset. post
