[yogarajkhanal]

hi,

in my report template i have static text field for the labels

and correspoding name filed for the parameter that i will pass from my program.

So my use case is like this

First Name:Yogaraj

Middle Name:Null

Last Name:Khanal

 

I have to remove the static text field Middle Name when the value is null can you please tell me how do i achieve it?

I saw something called print when expression in the properties of static text i am not sure if that will solve it ?can you please give me small example of print when expression if that solves it?

hi Yogaraj,

I can give u one simple example,
say there is a parameter called "OFFICE_ID", If u dont want to display one static text in your report when this "OFFICE_ID" parameter is null, Then do the following..

1. In printWhenExpression give this expression

            new Boolean($P{OFFICE_ID}==null) and also
              
           Set  RemoveLineWhenBlank is true.
 

The Code should be like the following,

 <staticText>
                    <reportElement x="196" y="0" width="100" height="20" isRemoveLineWhenBlank="true">
                          <printWhenExpression><![CDATA[new Boolean($P{OFFICE_ID}==null)]]>     </printWhenExpression>
                    </reportElement>
                    <textElement/>
                    <text><![CDATA[static text]]></text>
   </staticText>

 

Please try out this.

 

Thanks,

Hi Keerthi,

I tried as below but didn't work.Anything I am doing wrong here?

 

<staticText>

<reportElement

x="17"

y="286"

width="420"

height="19"

key="staticText-19"

isRemoveLineWhenBlank="true">

<printWhenExpression><![CDATA[new Boolean($P{rtf}==null)]]></printWhenExpression>

</reportElement>

<box></box>

<textElement>

<font fontName="Times New Roman" pdfFontName="Helvetica-Bold" size="12" isBold="true"/>

</textElement>

<text><![CDATA[Refusal to File Reasons:]]></text>

</staticText>

new Boolean($P{rtf}!=null) solved my problem

if any one have similar problem please contact me

Keerthi,

Do you know how do automatically shift the spaces up after i hide the static test by the field below it so that there is no gap in the page.Hope to hear back from you soon.

Thanks,

Have you ever spent some time in searching the forum before doing wild posts!?!??!?!? /tools/fckeditor/editor/images/smiley/msn/whatchutalkingabout_smile.gif

 

Anyway:

Take a look at the Attributes "RemoveLineWhenBlank " and also at "PositionType"

set "RemoveLineWhenBlank" of your elements that should be removed to "true" and "PositionType" of every element that should move upwards to "float".

There are also some samples provided with full JasperReports Download package that helps a lot.

Just my two cents

I am sorry I should have tried all options first.

Its getting 5 and i wanted to wrap my work so tried getting feedback from user community.

Anyway figured that out before you send me the suggestions.

I was opening new thread with the hope that if new users find the similar problems they will have more references.

I will read next time before I post.

Thanks for your suggestion.
