ActiveReport Truncate A Text

ActiveReport Truncate A Text

I make a Report in ActiveReport3.0 which has a Subreport. In my subreport,
in the Detail part actually, I have a textbox , that I bind my value to
the textbox.datafield. my value is a text in persian and it is also
long(about 8000 words).( I read the Value from Sql).I set the alignment of
the textbox to "rtl" because my text is in persian. then when I run my
app, the activereport truncate my text in persian (truncate it from left
and right of the textbox not at the bottom).what is the problem?
