more on stretch band and isPrintRepeatedValue

2003-02-26 09:33

Hi Teodor,

 

Maybe I did not make myself clear about stretching the band

 

1) The way I see it isRemoveLineWhenBlank work for the whole detail.

2) Basically what I want to do is to display a single row from the Record set as multiple lines considering some values. Thus one entry in the RecordSet will be displayed as 3 rows, the other one as 2 rows and some entries will be one row.

3) Some elements have printWhen conditions. The element coordinates are such that they are located one bellow the other - these are the rows I talk about. When the printWhen condition is true that there will be a "row". If it is false there is no row. Note that this is affected by a single entry from the RecordSet. Now the band does not stretched properly when I use isRemoveLineWhenBlank for the elements that I do NOT want to be displayed as a row. moreover I noticed that the last "row" does not get displayed although there is space reserved for it.

 

4) I do not want to print the elements with repeated values for a GROUP. When I use printWhenGroupChanges="true" isPrintRepeatedValues="false"

the values that repeat do not get displayes, but they are not displayed even when the group changes.

I will provide you with a simplified version of my band:

<reportElement positionType="Float" mode="Transparent" x="0" y="0" width="40" height="14" printWhenGroupChanges="true" isRemoveLineWhenBlank="true" isPrintRepeatedValues="false"/>

Hi,

 

I'm not sure I undestand what you want to achieve.

But I have one more suggestion to make.

Maybe if you split your detail band into 3 separate

bands that run together, using the trick explained

here might help:

 

http://jasperreports.sourceforge.net/tips.tricks.html#largebands

 

You can give up using the actual detail band and

use the group header sections of three dummy

groups with the same group expression:

 

<groupExpression>

$V{REPORT_COUNT}

</groupExpression>

 

Those group headers will behave exactly like a

normal detail band, but you have the advantage that

you can suppress the display of each group header

independently using the <printWhenExpression>

available at band level.

 

I hope this helps.

Teodor
