I am using JasperReports applied to my web application
I wanna put new page every time my date filed $F{date} change
I already tried drag break element with page break option from palette of iReport and drop it onto filed ->($F{date})
But nothing happened
please give me any advise or solution
Create two variables (in this order):
1. var_date_prev = $V{var_date}
2. var_date = $F{date}
Varibles are evaluated in order in which they are declared so var_date_prev will have date value from previous row.
Add property net.sf.jasperreports.export.xls.break.after.row on field after which you want to make page break and set the expression for the property
$V{var_date_prev} != null && $V{var_date_prev} != $V{var_date}

I have designed a report to pull data fields based on a record selection formula that uses a "like" operator that looks for a substring match in a particular field's data, as so:
{rct.serno} like "*9842*"
(due to the free-format way data is stored in the given field, I have to do a substring match to find the relevant rows in the DB.)
This works fine. Instead of manually editing the record selection formula every time, though, I thought to use a Parameter field ("{?TagNum}") to prompt the user for the desired string, and then use that in the record selection formula like:
{rct.serno} like "*{?TagNum}*"
Crystal does not throw an error when I save this record selection formula, but it does not return any records after the report is refreshed, and a parameter value is entered. How can I properly use the parameter value in a record selection substring match?
You're really close to the solution. You can modify the formula in the Select Expert. Just click the Select Expert icon (or from the Report menu). Then click the Formula Editor button. Concatenate or add an asterisk onto the beginning and end of the parameter using the + operator, like this:
{Customers.LastName} like "*" + {?pLastName} + "*"
Let me know if that helps.

I am trying to tick a check box on a form when I select one of many combobox values that begins with (REF) - this is code that stands for Referral closure.
this is what I've done..it's not working
Private Sub ReasonForInappriopriateReferral_AfterUpdate()
If Me.RsnForInappropriateRef.Value Like "(REF)*" Then
Me.Check66 = True
End If
End Sub
Please help, I was previously trying to conditional format a label to a different colour if the closure reason was a Referral closure, but couldn't do that either and think it could be down to the IF Like command.
I added two controls exactly as you indicated. I populated my combo by setting the Row Source Type to a Value List, and the Row Source to "Blah Blah";"(REF) - Jackson";"Two Times";"(REF) - Tyson"
I put this in the Click event of a button:
If Me.RsnForInappropriateRef.Value Like "(REF)*" Then
Me.Check66 = True
Else
Me.Check66 = False
End If
it behaved exactly as expected. I then moved it to the AfterUpdate event of the combobox, and again it worked flawlessly. The only thing I can see is that in your example, the combobox does not have the same name as your sub (ReasonForInappriopriateReferral vs RsnForInappropriateRef). Are you sure your names are right?
I am working on a jasper report, and I am trying to figure out a way for the report to page break on a variable change. The variable is actually a Field, and I put the value of the field in a variable.
Now, the Jasper Reports website has an example on how to break it by count like this
<groupExpression><![CDATA[new Boolean($V{BreakGroup_COUNT}.intValue()
> 5)]] ></groupExpression>
However, I am not sure of any way to compare the previous or next value and breaking after that.
You just want the report to start a new page when $F{MyField} changes value.
In this case simply create a group with 'Group Expression': $F{MyField}
Tick the option 'Start on a new page' for the group. There is no need for a variable.
Select the header of the group in the Document Structure window, and then select in the Properties window Start on New Page.
I have a grouping in my report that I want to use to link to another report. My dilemma is that I only want the link to be clickable when the value in the cell fulfills a certain criteria (number > x for example). If the condition isn't true, then I don't want the cell to be clickable. Is there a way to do this?
Edit: I've tried to set an IIF statement as part of the url, but what do I link to in the "false-part" of the statement? Using "" actually just refreshes the report, which isn't really what I want either. It also complains when I tried about:blank saying the url must start with http:// etc.
Use Nothing keyword in iif expression as false part. If Nothing is specified for Action than no link will be created.
=iif(YOUR_CONDITION, "Other Report", Nothing)
An action isn't dynamic so there's no way to turn it on and off based on a condition. But the expression you use to open another report can use an expression - whether you are using jump to report or the jump to URL action. One thing you might consider is for the condition when you don't want to jump to the other report is to jump to the same report. That is, let's say you are on Report A and you want to jump to Report B only when number > x. Then you use the expression:
=iif(number > x, "Report B", "Report A")
Report A will be cached so the net effect is that you didn't click even though the user can see the cursor change to a hand and can in fact execute a click.
I have to prepare a letter in which I require a 40 mm page header for first page and 20mm page header for all other pages except the first page. So I've created 2 page headers.
I want to hide/show the page headers based on the page number.
But when I write the following print when expression, it doesn't work.
$V{PAGE_NUMBER}.equals("1")
You need to check what the type of $V{PAGE_NUMBER} is... (I think it is java.lang.Integer)
The method you choose return a boolean an a PrintWhenExpression should return a java.lang.Boolean, so you need to instantiate one.
Try :
new Boolean($V{PAGE_NUMBER}.equals("1"))
It should work... To improve your test, I think that it is better to make a int comparison (a Java specialist should confirm that)
new Boolean($V{PAGE_NUMBER}.intValue() == 1)
The other manipulation you might have to do is specifying the whole object name (I don't know how JasperReport deals with import)
new java.lang.Boolean($V{PAGE_NUMBER}.intValue() == 1)
