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

This article applies to a Microsoft Access database (.mdb) and to 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.</li>  Place the following three labels in the report's report header section: <pre class="fixed_text">   Label: Name: Text1 Caption: ProductID

Label: Name: Text2 Caption: CategoryID

Label: Name: Text3 Caption: ProductName </li>  Set the OnPrint property of the report header section to the following macro: <pre class="fixed_text">   RepeatSubHeader.SubRH </li>  Set the OnFormat property of the report footer section to the following macro: <pre class="fixed_text">   RepeatSubHeader.SubRF </li> Create a new report called Categories Main Report based on the Categories table.</li> 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.</li>  Place the following text box in the Categories Main Report report's page header section: <pre class="fixed_text">   Text Box: Name: Flag Visible: No                   </li>  Place the following three text boxes in the Categories Main Report report's detail section: <pre class="fixed_text">   Text Box: Name: CategoryID ControlSource: CategoryID

Text Box: Name: CategoryName ControlSource: CategoryName

Text Box: Name: Description ControlSource: Description </li> 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.</li> 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.</li>  Set the OnFormat property of the report header section of the Categories Main Report report to the following macro: <pre class="fixed_text">   RepeatSubHeader.MainRH </li>  Set the OnPrint property of the page header section of the Categories Main Report report to the following macro: <pre class="fixed_text">   RepeatSubHeader.MainPH </li> Preview or print the report. Note that the subreport's header information is repeated when the subreport spans multiple pages.</li></ol>

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: <pre class="fixed_text">   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
