I am trying to manipulate a textbox display value of subreport from main
report's detail print() event.
The goal is this, if there is no record from database, replace the blank
space from textbox with message " No record found ".
I found the exact expression to reference my subreport textbox value
from main report, but when I tried to use IsNull() and Nz() function to
distinguish between blank and non-blank value, surprising it did not
work.
When there is no record in sub-report, the textbox's value is " /<you
entered an expression that has no value/> " in the watch window in debug
mode. I could not find a way around this.
Any expert?
Sincerely
Feng
