Hiding Subreports in SQL Report (RDL) - sql

I have a bunch of reports that are printed out and mailed to clients. At the top of the report is the return address, left aligned. I was asked to add an optional logo to the report. This logo should be left of the return address. (The logo and all other info is stored in the database). So if the logo exists, you SHOULD see:
<someimage> <Return Address>
And if no logo exists, you SHOULD see:
<Return Address>
There are many different logos possible placed in many different reports, so to make life easier, the logo was implemented as a subreport. The subreport just grabs the correct logo image, and then it automatically displays in the report.
The problem I'm having is this. If the log DOES NOT exist, then we want the return address left aligned, as shown above. But what is happening is that while the subreport shows nothing, it still takes up space where the logo would be, and the return address is floating a few inches to the right of the left side of the page.
<Return Address>
SO... is there a setting I can use/set to get the subreport to either not show, or not take up any space, if there is no logo to be displayed?
Sorry, hope I made this clear enough. I'm totally new to RDL's.

You should be able to set an expression on the subreport's visibility so that it does not show if there isn't a logo.
Here is the XML from an RDL I had handy:
<Subreport Name="SubReport">
<ReportName>SubReport</ReportName>
<Visibility>
<Hidden>=Not Parameters!ShowLogo.Value</Hidden>
</Visibility>
</Subreport>
This tests against a boolean parameter called ShowLogo, but you could just as easily test the value of another parameter (perhaps the length of a URL?).
To be clear, when specifying the expression for the "Hidden" property, you want it to evaluate to False when you want the element to display. If your expression evaluates to True, that means that the element will be hidden.

The method getKids() is undefined for the type PDField

https://issues.apache.org/jira/browse/PDFBOX-2148
When there are multiple copies with the same field name, the getFullyQualifiedName for each kid in the list of PDField objects returns the name of the parent, followed by .null. So if the parent field is called Button2 and it has 4 instances the result of printing out all the names will be:
Button2.null
Button2.null
Button2.null
Button2.null
According to the comments to the question, the OP refers to PDFBox 2.0.x versions, in particular 2.0.6.
getKids()
The method getKids() is undefined for the type PDField
In PDFBox 2.0.6 there are two immediate sub-classes of PDField. Different variants of the former (1.8.x) getKids() method are implemented in there:
PDNonTerminalField - the method retrieving the kids in this class is getChildren() and returns a List<PDField>, a list of form fields.
PDTerminalField - the method retrieving the kids in this class is getWidgets and returns a List<PDAnnotationWidget>, a list of widget annotations.
name of the parent, followed by .null
When there are multiple copies with the same field name, the getFullyQualifiedName for each kid in the list of PDField objects returns the name of the parent, followed by .null
This is not the case in PDFBox 2.0.x.
In the sample document attached to the PDFBox issue PDFBOX-2148 PDFBox now correctly finds only a single field which appropriately is named "Button2". This field is a PDTerminalField and has 4 widget annotations. The class of the latter, PDAnnotationWidget, has no getFullyQualifiedName method, so there are no ".null" names.
Thus, this problem is gone.
FQN of duplicate fields
(from the OP's comment responding to "What exactly is your question?")
how to get Fully Qualified Name of duplicate fields in pdfbox
There are no duplicate fields in (valid) PDFs, for a given name there is at most a single field which may have multiple widgets. Widgets do not have individual FQNs.
Thus, what you call "duplicate fields" in your example document actually is a single field with multiple widgets; the name of that field is "Button2" and can be retrieved using getFullyQualifiedName().
which page which form field
(from the OP's comments to this answer)
but how to get current page no in pdfbox.. for example there are 3 page and in page 2 there is a form field so how can i get which page which form field ?
All PDAnnotation classes, among them PDAnnotationWidget, have a getPage() method returning a PDPage instance.
BUT: As specified in ISO 32000-1, annotations (in particular form field widgets) are not required to have a link to the page on which they are drawn (except for screen annotations associated with rendition actions).
Thus, the above mentioned method getPage() may return null (probably more often than not).
So to determine the respective pages of your widgets, you have to approach the problem the other way around: Iterate over all pages and look for the annotation widgets in the respective annotation array.
For PDFBox 1.8.x you can find example code in this stackoverflow answer. With the information given in the previous parts of this answer it should be easy to port the code to PDFBox 2.0.x.
checkbox and radio button
(also from the OP's comments to this answer)
one more issue if i am using checkbox and radio button both then field.getFieldType() output is Btn for both. how to identify it?
You can identify them by inspecting the field flags which you retrieve via fields.getFieldFlags():
If the Pushbutton flag is set (PDButton.FLAG_PUSHBUTTON), the field is a regular push button.
Otherwise, if the Radio flag is set (FLAG_RADIO), the field is a radio button.
Otherwise, the field is a check box.
Alternatively you can check the class of the field object which for Btn may be PDPushButton, PDRadioButton, or PDCheckBox.
Beware: If a check box field has multiple widgets with differently named on states, this check box field and its widgets act like a radio button group! And not only in theory, I've seen PDFs with such check box fields in the wild.
To really be sure concerning the behavior of the fields, you therefore also should compare the names of the on states of all the widgets of a given check box.

Can <condPageBreak height='?cm'> change dynamically?

I have a <blockTable> that change size depending an user input.
I want to continue drawing on next page if there is no sufficient space to draw the blocktable on the same page.
<condPageBreak height='1in'/>
<blocklTable ...>
...
How can I change blockTable height to jump to the next page if there is not enough space on the current page?
I'm not sure about dynamically change or break page. But I use below method. May be it will useful to you.
Try with this RML reports.
The <condPageBreak/> tag is a "CONDitional Page Break". To use it, you give it a height in any units that RML can handle.
It then compares this height with the remaining available space on a page. If the space is sufficient, then the next elements are placed on the current page, but if there is less space than the height you have given it anything following the <condPageBreak/> is continued on the next page
<condPageBreak/> has only one attribute - the mandatory one of
height
For Example:
<condPageBreak height="1in"/>
<condPageBreak height="72"/>
For more details: RML User Guide
NOTE:
Use above examples before the start of <blockTable> tag
For Example:
<condPageBreak height="1in"/>
<blockTable style="Table4">
.
.
.
</blockTable>

XSL / XSL-FO: Different formatting of a block depending on its page position on PDF page

I'm new in this mailing list, so please apologize any of my wrongdoings.
FOP 1.1
Question: Is there any condition to find the position of a text-block in on PDF page.
This is the problem:
I need to change the formatting of a title-block depending on its position on the page.
If the title-block appears somewhere in the (vertical) middle of the page, I want to add a line on top of it.
if the title-block appears at the beginning/top of a page the line must not appear
Does XSL-FO have a way to do that?
From http://lists.w3.org/Archives/Public/www-xsl-fo/2015Sep/0002.html:
I used a white background on the
fo:region-before and a negative margin on the title to 'push' the
'border-before' of the title under the fo:region-before.
This requires that the FO processor supports negative values of
'margin-top', which is allowed but not required (http://www.w3.org/TR/xsl11/#margin-top). It also requires
that the FO processor will 'paint' the fo:region-before after painting
the fo:region-body.

Reporting Services - aligning Layout direction Tablix dynamic

Deal All,
Is there a way to have same report show in both layout direction based on parameter?
I have two data set one for label and one for data based on specific parameter show the labels
needed and the data needed but i am unable to switch the lay out direction it keeps LTR.
I need if anyone have an idea to change the layout direction from parameter.
I am having 50 reports and i don't like to have 150 reports because i am having 3 language.
I don't need to change the design of reports if there a new adding columns or changing columns.
I did it in data base by sending paramater name of the report and then get the dataset for it and then use the parameter of language to get label and data.
thanks in advance
I dont know if this helps, because I have no experience with RTL, however if you select a TextBox and open the properties via F4, you can select for the text direction not only LTR or RTL but also an expression. Maybe this gives you the flexibility, you are looking for?
Please right click on the report and choose view code or press F7 and insert below code for the field:
<Style>
<FontFamily />
<TextAlign>Right</TextAlign>
</Style>
and
<Direction>RTL</Direction>

Interactive Report Title defaults to 'Applicaiton'

I have an Interactive Report that displays Images in one column. The images are displayed directly from Images I loaded into shared components.
The report query:
SELECT
Tbl_P.ImagePackage,
Tbl_P.PRICE as PACKAGE_PRICE,
Tbl_I.ID,
Tbl_I.Name,
Tbl_I.PRICE,
Tbl_I.Type || Tbl_I.Name as Minifigure,
Tbl_I.Quote as QUOTE,
'AddToCart.png' as ADD_TO_CART
from "Tbl_090_ImagePackages" "Tbl_P"
left outer join "Tbl_091_Images" "Tbl_I"
on Tbl_P.ID = Tbl_I.Image Package
where Tbl_P.ID = :P201_GROUP
The column in question is 'ADD_TO_CART'.
The Column attributes are as follows:
Display Type: Display as Text(escape special characters)
Link Text:
<img src=#APP_IMAGES##ADD_TO_CART# alt=Application Express height=30 width=30
Link Attributes:
ID=#ID# class="AddToCart"
Target: Page in this Application (Current Page)
The Title is defaulting to 'Application' and I can't get rid of it or change it. I have tried changing the Link Attributes to: title="Testing" ID=#ID# class="AddToCart" Unfortunately this has not worked. Any help would be much appreciated.
Thank you
Seems like your link text is malformed? Put your attributes between quotes, single or double. When you view your page source with eg Firefox, you'll notice strings highlighted in red: these are invalid html. The browser is forgiving up to a certain point, but if you confuse it enough things like this may start happening.
<img src="#APP_IMAGES##ADD_TO_CART#" alt="Application Express" height=30 width=30 />
