How can I not print a Sub Report?

2004-05-05 09:39

OK, I got my master page working and I created four groups that print on a new page, and I can print and all five will print. But I need to not print some of the pages based on certain logic. How can I not print a sub-report defined from a group?

 

I tried setting the group expression, but no matter what I set it to it still prints the page or a blank page.

 

How can I completely turn one of them off?

Using the Sub-Report "Print When Expression" I can control if the sub-report gets called or not.

 

But still the group band is defined and I get a blank page. If I set the group band height to 0, I get a compile warning, but the page doesn't print. YEA.

 

But there doesn't seem to be a way to dynamically pass the group band height.

 

Any Help?

Doesn't work the "PrintWhenExpression" of your GroupHeader/GroupFooter Section(s)???

 

Just put the same expression you use for hiding your SubReport into your band-objects you want to hide.

 

I also managed not printing ColumnHeader on first page with the PrintWhenExpression of the ColumnHeaderBand-Object.

c-box,

 

Thank you for your response.

 

I have tried everything. I am using Jasper 5.0, using iReports 0.2.2 as my designer.

 

When I put in "new Boolean("FALSE")" into my PRINTWHENEXPRESSION for supressing the sub-report it doesn't run the sub-report but still a blank page prints. If I set the same expression above in the GROUPEXPRESSION of the group, it seems to have no affect. In fact nothing I set in the GROUPEXPRESSION to seems to have any effect. If I leave it blank or null, it still prints.

 

Am I missing something. Is there an expression I can test for on the group expression that will always supress the page?

Not the Groups's GROUPEXPRESSION, the Group's PRINTWHENEXPRESSION.

When I call a subreport from my group I see a PRINTWHENEXPRESSION, but that is only for the subreport. Does the group also have another PRINTWHENEXPRESSION OUTSIDE THE SUBREPORT?

 

Here is a little snap of my code:

 

<group name="PAGE_2" isStartNewColumn="false" isStartNewPage="true" isResetPageNumber="false" isReprintHeaderOnEachPage="false" minHeightToStartNewPage="0" >

<groupExpression><![CDATA[new Boolean($F{TEXT_02}.equals("N"))]]></groupExpression>

<groupHeader>

<band height="0" isSplitAllowed="true" >

</band>

</groupHeader>

<groupFooter>

<band height="120" isSplitAllowed="true" >

<subreport isUsingCache="true">

<reportElement

mode="Opaque"

x="0"

y="0"

width="610"

height="120"

forecolor="#000000"

backcolor="#FFFFFF"

positionType="FixRelativeToTop"

isPrintRepeatedValues="true"

isRemoveLineWhenBlank="true"

isPrintInFirstWholeBand="false"

isPrintWhenDetailOverflows="false">

<printWhenExpression><![CDATA[new Boolean($F{TEXT_02}.equals("N"))]]></printWhenExpression>

</reportElement>

<parametersMapExpression><![CDATA[$P{REPORT_PARAMETERS_MAP} ]]></parametersMapExpression>

<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>

<subreportExpression class="java.lang.String"><![CDATA[$P{IMAGE_PATH} + "xml/Form_9_p2_Master.jasper"]]></subreportExpression>

</subreport>

</band>

</groupFooter>

</group>

of course the bands also have a "PrintWhenExpression"...

 

your code should be:

 

<group name="PAGE_2" isStartNewColumn="false" isStartNewPage="true" isResetPageNumber="false" isReprintHeaderOnEachPage="false" minHeightToStartNewPage="0" >

<groupExpression><![CDATA[new Boolean($F{TEXT_02}.equals("N"))]]></groupExpression>

<groupHeader>

<band height="0" isSplitAllowed="true" >

<printWhenExpression><![CDATA[new Boolean($F{TEXT_02}.equals("N"))]]></printWhenExpression>

</band>

</groupHeader>

<groupFooter>

<band height="120" isSplitAllowed="true" >

<printWhenExpression><![CDATA[new Boolean($F{TEXT_02}.equals("N"))]]></printWhenExpression>

<subreport isUsingCache="true">

<reportElement

mode="Opaque"

x="0"

y="0"

width="610"

height="120"

forecolor="#000000"

backcolor="#FFFFFF"

positionType="FixRelativeToTop"

isPrintRepeatedValues="true"

isRemoveLineWhenBlank="true"

isPrintInFirstWholeBand="false"

isPrintWhenDetailOverflows="false">

<printWhenExpression><![CDATA[new Boolean($F{TEXT_02}.equals("N"))]]></printWhenExpression>

</reportElement>

<parametersMapExpression><![CDATA[$P{REPORT_PARAMETERS_MAP} ]]></parametersMapExpression>

<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>

<subreportExpression class="java.lang.String"><![CDATA[$P{IMAGE_PATH} + "xml/Form_9_p2_Master.jasper"]]></subreportExpression>

</subreport>

</band>

</groupFooter>

</group>

 

If you are using iReport (current version) then you can easily edit the "PrintWhenExpression" of bands over GUI.

Sorry, you're right, the Band has a PrintWhenExpression, not the group.

 

There is a wealth of information available at the jasperReports website. Sometimes it is helpful to check there when syntax questions come up. For example, here is a quick reference page that could have help you find your answer: http://jasperreports.sourceforge.net/quick.reference.html

OK, COOL. That fixed it. I can't believe I over looked the Band Print When Expression in Ireports for so long. I must've looked at the screen 1000 times trying to solve this problem.

 

Thanks!
