Communication between report & his subreport

2003-03-18 05:18

I have subreport, in which I defined some my variables.

Problem: I want to read the value of my subreport's variables from master report. Is there any way can I do it ?

Thanks for answer in advance.

hi, i don't know if that is possible.

But i can suggest something, but i'm not sure if it works.

 

You can try to define your variables not in the subreport. Define them into your master report, and pass to the subreport like parameters with the subreportParameter expression.

In this way you can modify the parameter value in the subreport, and this value is reflected in the master report.

But you migth take an advertence.

This can work, only if the parameter passing is by reference, and not by value.

but i'm not sure of this... you can ask to teodor, whats is the method of the parameters passing.

 

Bye...

 

PD: If this works, tell me.
