ACC2000: How to Repeat Subreport Header at Top of Page

ID: Q231808

The information in this article applies to:

Microsoft Access 2000

Moderate: Requires basic macro, coding, and interoperability skills.

This article applies to a Microsoft Access database (.mdb) and a Microsoft Access project (.adp).

SUMMARY

This article describes how to repeat a subreport's header when the subreport spans multiple pages.

NOTE: This method works best for one subreport. Attempting to repeat the subreport header for multiple subreports requires a set of controls in the page header and a flag for each subreport. Then the code must check each flag and hide or show the appropriate sets of controls. This code is not easy to maintain.

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:

Open either the Northwind.mdb or the NorthwindCS.adp sample database file.

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

Create a new report called Products Sub Report based on the Products table.

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

On the View menu, click Report Header/Footer.

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

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


    RepeatSubHeader.SubRH

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


    RepeatSubHeader.SubRF

Create a new report called Categories Main Report based on the Categories table.

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.

Place the following text box in the Categories Main Report report's page header section:


    Text Box:
       Name: Flag
    Visible: No

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

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.

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.

Set the OnFormat property of the report header section of the Categories Main Report report to the following macro:


    RepeatSubHeader.MainRH

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


    RepeatSubHeader.MainPH

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
