When is the formula "PageNumber" calculated in Crystal Reports?
All my report data is contained within a single section in Group Footer 3A, (with "Keep Together" ticked in the Section Expert) so that a single record will never be broken across a page break.
In Section Group Footer 3B I have empty space. In a printed report, this is space for handwritten comments. Because it is a separate section, the page break may occur between Section 3A and section 3B. In this case, I want to suppress Section 3B when it is at the top of a page.
In Group Footer 3A, I used a formula called setPreviousPageNumber to store the page number that section 3A is printed within:
//setPreviousPageNumber Global Numbervar previousPageNumber := PageNumber;
* After the initial post, I also tried putting setPreviousPageNumber in the Page Footer Section
Then in Group Footer 3B I set a conditional suppression formula:
//Conditional Suppression for Group Footer 3B previousPageNumber <> PageNumber;
My reasoning was that Section 3A would be on (for example) PageNumber 4, and if Section 3B was on PageNumber 5, then suppress it.
However I find my formula to setPreviousPageNumber in Section 3A results in a strange anomaly.
The formula in 3A sets the variable previousPageNumber to be (for example) 4.
When I use a formula to display the value of previousPageNumber in3B, it has mysteriously already incremented to 5.
//printPreviousPageNumber WhilePrintingRecords; Global Numbervar previousPageNumber;
All these formulas are whileprintingrecords;
I have tried displaying both the PreviousPageNumber and the CurrentPageNumber in section 3B, and can see they are different. However, whenever I try to perform the comparison inside the Section Expert, I never get the result I want. Either the section is never suppressed, or it is always suppressed.
Does anyone have some insight on how I can suppress a section based on the page number of the previous section?
I'm using Crystal Reports 184.108.40.2062
