Null values cause row height to change

I have a fairly simple report with several columns in the detail section. I
have set the row height to 0.15in (text is 6pt) and set both CanGrow = false
and CanShrink = false for all textboxes in the row.
The report always renders perfectly in the Visual Studio preview tab and
when exporting to PDF, but I run into problems when viewing it on the report
server webpage. Any row with a Null value in one of its fields is rendered
twice as high as the nomal rows. If I change my query so that it doesn't
return nulls, all of the rows render with the same height as expected.
Anyone else run inot this behaviour?I found a cheap way to get around the problem by replacing null values in my
report with a single space. I used expressions like the following:
=iif(IsNothing(Fields!MyField.Value)," ",Fields!MyField.Value)
This is a pain to have to enter in every field though. I would still like to
know a way to get it to render properly in HTML without having to go to all
this trouble.|||there are two options in ADVANCED PROPERTIES of the textbox (or cell of
a table) which meant expand the textbox to accomodate the data and
shrink the textbox to accomodate the data i think by unchecking those
options (ie not allowing shrinking/expansion of textbox) will resolve
the problem check that out n let me know what result comes out
thanx
