How to use region.shiftrelativeto and to position the region NOT above a certain value

rbuser

Hello,

I have a title band with several regions in it.

Every region has dynamic height and shifts relative to the previous region.

The last region should be positioned at e.g. "max(150, actualPosition)"
- it should not be above 150, but can be below, if it is necessary. In
other words I need dynamic white space between the second last and last
region.

I searched in the wiki and the forum and played around with
Band.BeforePrint / BeforeGenerate / AfterGenerate / AfterPrint and
Region.OnDrawCommandCreate (to get the actual position of the region),
but always something went wrong (e.g. moving the region after it was
rendered doesn't retrigger rendering, so pagebreaks could be wrong).

Is there a way to achieve what I need?

Thanks in advance!
Klaus

Hi Klaus,

One option would be to place an empty static region between the second
to last and last regions (shift relative to). This would ensure the
final two regions are always spaced apart.

Hi Nico,

Thanks for your answer.

I'm not sure if I understand correctly.

What I currently have is:

R1: Top 0 cm, stretchable (height at runtime can be between 5 and 25 cm)
R2: Top 15 cm, shift relative to R1

Actual result:

R1.Height = 5 cm -> R2.Top = 5 cm (plus something)
R1.Height = 15 cm -> R2.Top = 15 cm
R1.Height = 20 cm -> R2.Top = 20 cm

But the desired result is:

R1.Height = 5 cm -> R2.Top = 15 cm
R1.Height = 15 cm -> R2.Top = 15 cm
R1.Height = 20 cm -> R2.Top = 20 cm


Do I understand your suggestion correctly?

R1: Top 0 cm, stretchable
R empty: empty, Top 14 cm, not stretchable, no shift relative
R2: Top 15 cm, shift relative to R-empty

In that case R2 could be overwritten by content of R1.

BTW: Cannot set "stretch = false" for a region, at least my designer
doesn't let me doing this.

Best regards,
Klaus

Hi Klaus,

Which version of ReportBuilder are you using? Using RB 17.02, it is
possible to toggle the Stretch property of a Region.

Looking at your requirements, it appears you would like the first region
to grow (stretch) until it begins to overlap the second region at which
time you would like the second region to begin shifting relative to the
first?

ReportBuilder does not have any built-in features to handle this type of
layout.

Basically you would need to determine the height of the region before
the report prints (either by estimating its contents or generating the
report twice), then based on that information, toggle the
ShiftRelativeTo property based on whether the two regions will overlap
or not.
