JasperReport - wrap text to show long text in textfield

Question

I am using jasper report as reporting tool in my application. And I am wondering how can i wrap the long text by expanding the reportElement dynamically into vertical direction ( expanding the row size, not column width). Or Is there any way to achieve this? My approach below is truncating the long text "Some very long name". Can you please give me some suggestions?

Answer 1

StretchHeight is truncating my data in the subreport when it falls on the page break

Answer 2

Go to the Text Field Properties then set Text Adjust to StretchHeight.

Answer 3

Also you can make the truncation elegant by using the following properties set to the textfield. Check this sample

net.sf.jasperreports.text.truncate.at.char 
net.sf.jasperreports.text.truncate.suffix 
net.sf.jasperreports.print.keep.full.text 

Answer 4

I found the answer myself :

I did some extra research about the properties of textField and rectangle components. And found that I need to set the following properties.

For rectangle :

        <rectangle>
            <reportElement stretchType="RelativeToBandHeight" ... />
        </rectangle>

For textField :

        <textField isStretchWithOverflow="true">
            ...
        </textField>

Output as expected :

The <detail> ...</detail> section after correction :

<detail>
        <band height="21" splitType="Stretch">
            <rectangle>
                <reportElement stretchType="RelativeToBandHeight" x="0" y="0" width="88" height="21"/>
            </rectangle>
            <textField isStretchWithOverflow="true">
                <reportElement x="2" y="0" width="84" height="21"/>
                <textElement verticalAlignment="Middle"/>
                <textFieldExpression><![CDATA[$F{personName}]]></textFieldExpression>
            </textField>
            <rectangle>
                <reportElement stretchType="RelativeToBandHeight" x="88" y="0" width="122" height="21"/>
            </rectangle>
            <textField isStretchWithOverflow="true">
                <reportElement x="90" y="0" width="118" height="21"/>
                <textElement verticalAlignment="Middle"/>
                <textFieldExpression><![CDATA[$F{address}]]></textFieldExpression>
            </textField>
        </band>
    </detail>

UPDATE

You can also set property net.sf.jasperreports.print.keep.full.text to true to achieve that across your all reports.
