Dynamically set PageHeaderSection height

[Wayne]

Hi,

I have a standard report with: PageHeaderSection,  GroupHeaderSection -  DetailSection etc. My problem is the paper on which the report is being printed on, it may have a pre- printed Logo on the top. What I need is to dynamically set the page margin or better the PageHeaderSection height. But it seems this is not possible. Could you please give me a solution to this problem.

Thank you and Kind regards
Wayne

Hello Wayne,

Generally speaking the paging is the process of fitting as many as possible report items into a page. In order to do this first we have to define the available space for the content (the report items) on the page. The available space is usually calculated from the page size minus the page margins and the page sections. So your assumption is correct, it is not possible to have a dynamically sized page section for different pages of a single report. If the size would be different for the whole report, then you can change it through the PageSettings API.

Hi.
I think I have similar issue - I need to hide some parts of the header depending on page number - lets say: show image on first page, hide it in second, show in third etc.

After Your respond I assume that this is also not possible. Am I right or is there any way to achieve that?

Hi Michal,

What you want is possible as you hide an item inside page section and do not change its size. You can use the built-in PageNumber and PageCount objects in a Bindings expression for the Visible property of that item e.g.:

Property Path                                              Expression
========================================================
Visible                                                  =IIF(PageNumber %2 = 0, true, false)

then would it shrink back to fill the hidden space ?

Hello Einar,

Setting the page sections Visible properties causes the sections to be displayed or not. The occupied space would not shrink as explained in the Report Structure and Understanding Rendering Behaviors help articles.
