Problems with long text fileds in Crystal Report Viewer

I'm using Crystal Reports for Visual Studio 2010 (13.0.2000.0).

I have a report that shows a list of columns.

One of this columns shows a description field that can be very large. I didn't Check the option "Can Grow" of this field.

When I see the "Main Report Preview" it shows ok, in the report only shows part of the content of that field.

But when I see the report inside a ASP.NET web page, into a Crystal Report viewer, it shows all the text of that field, so it overwrites the content of the next column.

Is it a Bug?

How can I fix that?

Thanks,
