Stretch a row if data overflows in jasper reports

问题:

how do i stretch a row when data overflows the band height in jasper reports, I have set the stretch with overflow flag as true but it doesn't work.

回答1:

I ran into this problem myself. I could not get the detail band to stretch, even though the text field in the band was configured to do so. The problem was with the report's Print Order property, which for some reason had been set to horizontal. When I changed it to vertical, the problem went away.

According to the JasperReports Ultimate Guide,

When filling report templates horizontally, dynamic text fields inside the detail section no longer stretch to their entire text content, because this might cause misalignment on the horizontal axis of subsequent detail sections.

My band stretches if necessary with the following conditions, I do not know yours. I have started with the ireport 1.0 netbeans plug-in and jasper 3.5.2. The Split type for the band has been set to Stretch.

<band height="108" splitType="Stretch"></band>

The Stretch with overflow for the field has been checked, e.g.:

<textField isStretchWithOverflow="true">
    <reportElement positionType="Float" x="70" y="28" width="485" height="14"/>
        <textElement>
            <font size="10"/>
        </textElement>
        <textFieldExpression class="java.lang.String"><![CDATA[($F{EQUIPMENTS} == null ? "-" : $F{EQUIPMENTS})]]></textFieldExpression>
</textField>

isn't that set the height enough tall, and the property overflow, then it will automatically overflow to multiple rows? such solution works for me.
