Dynamic Element Formatting

[chandu_517]

Hi all,

I'm new to ireports. I require the font style for data to be displayed dynamically based on some condition which is explained below.

I have three Fields x,y,z to compare. if x < y or  x>z  then the data color for x should be changed to 'red' else data color of x should be in black color.

please advice me as to how to proceed on this & where to validate.This requriement is for a swing window application.

Thanks in advance

Regards,

Chandu

Add a conditional Style. Or use Print When Expression.

Hi,

Can you expand your explanation using some code snippet also where to do it.

Hi Chandu,

which version of iReport do you use? In version 3.6.0 you'll find the Styles in the Report Inspector. There you have to add a Style (the way the field normally should look like) by right clicking on the word "Styles". After that you can add a conditional style.

Hi Christina,

have you information about parametric styles?

with "parametric" I mean styles that accept parameter for background colors, font dimension etc...

i.e.:

        <conditionalStyle>
            <conditionExpression><![CDATA[new Boolean ($F{COL4}.matches("ddd"))]]></conditionExpression>
            <style
                name="AlternativeStyle"
                isDefault="false"
                backcolor="$P{aColor}"
                fontSize="$P{aValue}"
            />
        </conditionalStyle>

 

so, aColor, aValue can be read from a DB or passed to the report dinamically...

thanks...
