Can I hide a SubReport based on a Variable OnCalc event

rbuser

Hi,

I have a Variable in the footer of a sub report that calculates whether or
not the sub report should be visible. However I cannot actually hide the sub
report in Report Builder 7.04. Does anyone have any ideas?

Hi Dan,

Where are you checking the value of the variable and setting the visibility
of the subreport? You might try creating a two pass report and checking the
value and assigning hte visibilty of the subreport on the first pass.

If I add the following code on the the OnEndFirstPass report I cannot
compile. I get the following message 'Undeclared identifier SubReport1'
despite dragging the visible property from the properties sub report.

if (DBCalc1.Value <= 10) then
begin

SubReport1.Visible := false;

end;

Hi Dan,

Sorry, I did not realize you were using RAP. For future reference please
post all RAP related questions to the RAP newsgroup.

You will need to create a global variable that references the Subreport1
object to access it inside the actual subreport. Take a look at the
following demo I created for an example of how to do this in RAP.
