Set Child band invisible

stewag25

Why does this code from within Delphi does not set the FR child band invisible?

frxReport1.FindObject('Child1').Visible := false

gpi

This code should work. Check your code and script

I figured out that is DOES work when standing alone.
In order not to show a blank child band if the only contained field is empty though, I use this code in OnBeforePrint:

wrote:

if <frxDBqPacklist."Comment"> = '' then
Child1.visible := false
else
Child1.visible := true

This of renders the setting in Delphi obsolete, of course.

Is there a simple way not to show a empty child band?
Or how could I tell FR that the above code should only be executed if child1 shall be displayed at all?
(It is an optional information that the user chooses to display or not display before print)

Use in the Delphi:

frxReport1.Script.Variables['HideChild'] := False;

in the script:

if (<frxDBqPacklist."Comment"> = '') or (HideChild) then
Child1.visible := false
else
Child1.visible := true

... thanks gpi.

When I put:

wrote:

var
HideChild1: TfrxVariable;

in Delphi, I get an "undefinied identifier" error.

Do I need to add a library to uses?

It seems as if i don't declare HideChild1 variable I get an undefined identifer in FR.

Also, adding Hidechild1 variable in FR does not help (screenshot).
?

gpi

frxReport1.Script.Variables['HideChild'] := False;

Add script (not report) variable. Use my code only

This script will be works in the run-time only.
If you want - you may use report variable instead of script variable
