How to stretch subreport following parent

Posted on October 15, 2016 at 5:12am

Hi.

I have two reports: main and subreport.

In main detail band i have textfield and subreport:

<band height="15" splitType="Stretch">
    <property name="com.jaspersoft.studio.unit.height" value="pixel"/>
    <textField isStretchWithOverflow="true" isBlankWhenNull="true">
        <reportElement style="cell" stretchType="RelativeToBandHeight"
                       x="20" y="0" width="200" height="15"
                       isPrintWhenDetailOverflows="true"/>
        <textElement textAlignment="Center" verticalAlignment="Middle">
            <font fontName="DejaVu Sans" size="7" isBold="true"/>
            <paragraph leftIndent="1" rightIndent="1" spacingBefore="1"
                       spacingAfter="1"/>
        </textElement>
        <textFieldExpression><![CDATA[$F{org_name}]]></textFieldExpression>
    </textField>
    <subreport>
        <reportElement stretchType="RelativeToTallestObject" x="220" y="0"
                       width="582" height="15" isPrintWhenDetailOverflows="true">
            <property name="com.jaspersoft.studio.unit.width" value="pixel"/>
        </reportElement>
        <subreportParameter name="SUBREPORT_DIR">
            <subreportParameterExpression>
                <![CDATA[$P{SUBREPORT_DIR}]]>
            </subreportParameterExpression>
        </subreportParameter>
        <dataSourceExpression><![CDATA[$F{EDU_LEVEL_DATASOURCE}]]></dataSourceExpression>
        <subreportExpression>
            <![CDATA[$P{SUBREPORT_DIR}
                     + "/reports/scholarship_fund_analysis/sub_education_level.jasper"]]>
        </subreportExpression>
    </subreport>
</band>

And there is one textfield in subreport's detail band.

The purpose is to implement something like rowSpan for "org_name" textField in main report. it works fine when subreport has a lot of content.

The problem arises when org_name is too long, and subreport has few rows. The height of org_name textfield is greater than total height of subreport.

Result report looks like this:



Is it possible to fix this?
