ACC2002: How to Repeat Subreport Header at the Top of a Page (299019)

MORE INFORMATION

The method demonstrated in the following example uses a flag in the page header to indicate whether the subreport spans multiple pages. When the subreport's report header is printed, the flag is set to 1. When the subreport's report footer is printed, the flag is set to 0. When the page header is printed, if the flag is set to 1, then the subreport spans multiple pages and the subreport's header should be repeated.

The following example demonstrates how to cause a subreport's header to be repeated if the subreport spans multiple pages:

1. Open either the Northwind.mdb or the NorthwindCS.adp sample database file.
2. Create the following macro and then save it as RepeatSubHeader:

      Macro Name   Condition   Action
      ------------------------------------
      MainRH                   SetValue
      MainPH       [Flag]=0    CancelEvent
      SubRH                    SetValue
      SubRF                    SetValue
   
      MainRH Actions
      ------------------------------------------------
      SetValue
         Item: Reports![Categories Main Report]![Flag]
         Expression: 0
   
      SubRH Actions
      ------------------------------------------------
      SetValue
         Item: Reports![Categories Main Report]![Flag]
         Expression: 1
   
     SubRF Actions
     ------------------------------------------------
     SetValue
        Item: Reports![Categories Main Report]![Flag]
        Expression: 0
   					

3. Create a new report called Products Sub Report based on the Products table.
4. Place the following three text box controls in the new report's detail section:

       Text Box:
                Name: ProductID
       ControlSource: ProductID
   
       Text Box:
                Name: CategoryID
       ControlSource: CategoryID
   
       Text Box:
                Name: ProductName
       ControlSource: ProductName
   					

5. On the View menu, click Report Header/Footer.
6. Place the following three labels in the report's report header section:

       Label:
          Name: Text1
       Caption: ProductID
   
       Label:
          Name: Text2
       Caption: CategoryID
   
       Label:
          Name: Text3
       Caption: ProductName
   					

7. Set the OnPrint property of the report header section to the following macro:

       RepeatSubHeader.SubRH
   					

8. Set the OnFormat property of the report footer section to the following macro:

       RepeatSubHeader.SubRF
   					

9. Create a new report called Categories Main Report based on the Categories table.
10. Copy the controls from the Product Sub Report report's report header section and paste them into the page header section of the Categories Main Report report.
11. Place the following text box in the Categories Main Report report's page header section:

        Text Box:
           Name: Flag
        Visible: No
    					

12. Place the following three text boxes in the Categories Main Report report's detail section:

        Text Box:
                 Name: CategoryID
        ControlSource: CategoryID
    
        Text Box:
                 Name: CategoryName
        ControlSource: CategoryName
    
        Text Box:
                 Name: Description
        ControlSource: Description
    					

13. Embed the Products Sub Report report into the Categories Main Report report by dragging the Products Sub Report report from the Database window to the detail section of the Categories Main Report report.
14. On the View menu, click Report Header/Footer to add a report header and footer to the main report. If you do not want a main report header or footer, set the header or footer section's Height property to 0.
15. Set the OnFormat property of the report header section of the Categories Main Report report to the following macro:

        RepeatSubHeader.MainRH
    					

16. Set the OnPrint property of the page header section of the Categories Main Report report to the following macro:

        RepeatSubHeader.MainPH
    					

17. Preview or print the report. Note that the subreport's header information is repeated when the subreport spans multiple pages.

Displaying Main Report Information on Every Page

The previous example assumes that you do not want anything except the subreport header to be printed in the main report's page header. If you do want to print other information, you will need to hide and unhide each subreport header control in the page header. Change the MainPH macro in step 2 of the previous example to:

    Macro Name   Condition   Action
    ------------------------------------------------------
    MainPH       [Flag]=0    SetValue
                                     Item: [Text1].visible
                               Expression: False
                ...         SetValue
                                     Item: [Text2].visible
                               Expression: False
                ...         SetValue
                                     Item: [Text3].visible
                               Expression: False
                [Flag]=1    SetValue
                                     Item: [Text1].visible
                               Expression: True
                ...         SetValue
                                     Item: [Text2].visible
                               Expression: True
                ...         SetValue
                                     Item: [Text3].visible
                               Expression: True
