How to remove extra space between textfield in JasperReports?
jasper-reports
Solution
You can use 3 `textField` elements with `isRemoveLineWhenBlank` property set to `true` value.
The sample (jrxml file):
<?xml version="1.0" encoding="UTF-8"?>
<jasperReport .. topMargin="0" bottomMargin="0">
<parameter name="parameter1" class="java.lang.String">
<defaultValueExpression><![CDATA[null]]></defaultValueExpression>
</parameter>
<parameter name="parameter2" class="java.lang.String">
<defaultValueExpression><![CDATA[null]]></defaultValueExpression>
</parameter>
<parameter name="parameter3" class="java.lang.String">
<defaultValueExpression><![CDATA[null]]></defaultValueExpression>
</parameter>
<title>
<band height="102" splitType="Stretch">
<textField isBlankWhenNull="true">
<reportElement x="163" y="9" width="100" height="20" isRemoveLineWhenBlank="true"/>
<box>
<topPen lineWidth="1.0"/>
<leftPen lineWidth="1.0"/>
<bottomPen lineWidth="1.0"/>
<rightPen lineWidth="1.0"/>
</box>
<textElement/>
<textFieldExpression><![CDATA[$P{parameter1} == null ? null : "Parameter1: " + $P{parameter1}]]></textFieldExpression>
</textField>
<textField isBlankWhenNull="true">
<reportElement x="163" y="29" width="100" height="20" isRemoveLineWhenBlank="true"/>
<box>
<topPen lineWidth="1.0"/>
<leftPen lineWidth="1.0"/>
<bottomPen lineWidth="1.0"/>
<rightPen lineWidth="1.0"/>
</box>
<textElement/>
<textFieldExpression><![CDATA[$P{parameter2} == null ? null : "Parameter2: " + $P{parameter2}]]></textFieldExpression>
</textField>
<textField isBlankWhenNull="true">
<reportElement x="163" y="49" width="100" height="20" isRemoveLineWhenBlank="true"/>
<box>
<topPen lineWidth="1.0"/>
<leftPen lineWidth="1.0"/>
<bottomPen lineWidth="1.0"/>
<rightPen lineWidth="1.0"/>
</box>
<textElement/>
<textFieldExpression><![CDATA[$P{parameter3} == null ? null : "Parameter3: " + $P{parameter3}]]></textFieldExpression>
</textField>
<staticText>
<reportElement x="163" y="73" width="100" height="20"/>
<box>
<topPen lineWidth="1.0"/>
<leftPen lineWidth="1.0"/>
<bottomPen lineWidth="1.0"/>
<rightPen lineWidth="1.0"/>
</box>
<textElement/>
<text><![CDATA[Static text]]></text>
</staticText>
<line>
<reportElement x="63" y="6" width="447" height="1"/>
</line>
<line>
<reportElement x="73" y="96" width="447" height="1"/>
</line>
</band>
</title>
</jasperReport>
The report design in `iReport`:
For the parameter1=null, parameter2=null, parameter1=value3 the result will be:
UPDATE
For solving the problem of moving up the `textField` in case the element above was hide you can use the `Frame` container. You should add 2 frames (one per column) and put 2 `textField` elements (2 rows) in each frame.
The sample (jrxml file):
<?xml version="1.0" encoding="UTF-8"?>
<jasperReport .. topMargin="0" bottomMargin="0">
<parameter name="par1" class="java.lang.String">
<defaultValueExpression><![CDATA[null]]></defaultValueExpression>

<defaultValueExpression><![CDATA[null]]></defaultValueExpression>
</parameter>
<parameter name="par3" class="java.lang.String">

The report design in `iReport`:
For the par1=null, par2=2, par3=3, par4=4 the result will be:
You can compare the results - left side is done without using `frame` and the right side with `frame` elements.
Problem
I have created three text field in Header. I have put parameter in all `textField` elements. When I'm not calling one of three parameter of three `textField` elements. It will show 2 `textField` elements. The problem now is there are space between the text fields. How to remove the space? This is my code: ``` <textField isBlankWhenNull="true"> <reportElement x="0" y="18" width="555" height="35" isRemoveLineWhenBlank="true"/> <textElement textAlignment="Center"> <font size="12"/> </textElement> <textFieldExpression><![CDATA[$P{daterangefrom} && $P{daterangeto} ? "From ( " + $P{daterangefrom} + " - " + $P{daterangeto} + ")" : $P{weeks} && $P{monthy} && $P{yrs} ? "For week " + $P{weeks} +" "+ $P{monthy} +" "+ $P{yrs} : $P{monthy} && $P{yrs} ? "For monthly " +$P{monthy} +" "+ $P{yrs} : $P{quarter} && $P{yrs} ? "For Quarter " + $P{quarter} +" "+$P{yrs} : $P{yrs} ? "For " + $P{yrs} : null]]> </textFieldExpression> </textField> ``` This is mine result:
