Alternate row background colors?

2003-08-12 11:08

Is there a way to alternate the background colors between rows in a detail section?

 

I would like to mimick the look that quicken has to make it easier to view multiple rows with lots of data.

 

Thanks

Daniel

Search the forum (left hand side under *Register New Project*) for this question, I've seen it answered a few times in the past.

 

Not sure if you didn't see the search option, I didn't at first either.

 

Rock on,

In my haste, I missed the search box. I know better now :-)

Yes. You have to use a pair of printWhenExpressions and duplicate your detail XML exception for the background color and the printWhenExpression.

 

Example:

 

<textField isBlankWhenNull="true">

<reportElement x="0" y="0" width="80" height="16" forecolor="#000000" backcolor="#E5E5CC" mode="Opaque">

<printWhenExpression>new Boolean($V{REPORT_COUNT}.intValue() % 2 == 1)</printWhenExpression>

</reportElement>

<textElement textAlignment="Center" lineSpacing="Single" verticalAlignment="Middle"/>

<textFieldExpression class="java.lang.String">

$F{month}

</textFieldExpression>

</textField>

<textField isBlankWhenNull="true">

<reportElement x="0" y="0" width="80" height="16" forecolor="#000000" backcolor="#CCCC99" mode="Opaque">

<printWhenExpression>new Boolean($V{REPORT_COUNT}.intValue() % 2 != 1)</printWhenExpression>

</reportElement>

<textElement textAlignment="Center" lineSpacing="Single" verticalAlignment="Middle"/>

<textFieldExpression class="java.lang.String">

$F{month}

</textFieldExpression>

</textField>

Hi,

I'm just starting to research JasperReports and JFreeReports for use in some software. We use alternating row colors in just about every report and will have upwards of 100 different reports. So the solution for this functionality provided here doesn't seem reasonable for my particular needs. So my question is, does the JasperReports architecture make it straight forward enough to make a reusable component for something like this? In other words, can I somehow make a class or extend a class or method that I can just call so I don't have replicate a whole bunch of XML and column names just to alternate row colors for each report?

This is just one example. I guess the 'bigger' question would be, how extensible/customizable is JasperReports for when I have unique requirements.

 

Thanks for your input.
