Highlight Row in Interactive Report

Recently I encountered a question on the OTN Forum about "How to Highlight a Current Row in an Interactive Report". For a regular report that kind of highlighting is a built-in functionality in the template, but an IR doesn't have a (editable) template (could be a nice enhancement for a future version though!). But you can override the styles used by an IR, by adding some STYLE tags in the Page HTML Header. First take a look at the on-line demo. You can click the [Edit] button to see the highlighting in action.

So how do we achieve that:
First we need to add a function call to the [Edit] link/button in the IR: Add "onclick=highLight(this);" to the Link Attributes property of the Link Column. This click calls a "highLight" function, defined in the Page HTML Header:

function highLight( pThis ){
$('td').removeClass('current');
$(pThis).parent().parent().children().addClass('current') ;
var empno = $(pThis).parent().next().html();
$s('P36_CUR_EMP', empno);
refreshReport( empno, 'P36_CUR_EMP' );
}
The "refreshReport" is a wrapper for some (standard) APEX functions to execute a Partial Page Refresh of the detail region on the right side of the page. The rest of the code is some jQuery stuff, first do a clean up to remove all "current" classes from the TD-tags - to "un-highlight" a previous selection - and subsequently add that class to all TD's in the current TR.

Next define a "current" style to your own taste. In this example I used:

.current
{
background : transparent url(#WORKSPACE_IMAGES#row-over.gif) repeat-x scroll 0 0 !important;
border-bottom : 1px solid red !important;
border-top : 1px solid red !important;
}
I also tweaked the standard "apexir_WORKSHEET_DATA" styles a bit to get a hover effect:

.apexir_WORKSHEET_DATA tr:hover {
background:#EFEFEF url(#WORKSPACE_IMAGES#row-over.gif) repeat-x scroll left top;
}
- and did some other restyling on the look-and-feel as well - but that's about it!

Roel,

That's pretty cool!

I also like your use of the IR for navigation while showing the detail on the right. I hadn't thought of that.

Thanks for sharing,

Stew

can you explain where do you do the style change?
Roel said…
The link has an attribute : onclick=highLight(this);
That will change the style using that javascript function.
vamshi said…
refreshReport( empno, 'P36_CUR_EMP' );

I have multiple regions in a page how will this function know which region to refresh ?
Roel said…
Because it takes the current item as a starting point. Then it "moves up" to the current row and highlights it.
Vamshi said…
Could you please tell me the query of Emp Details Table ?

and when I try to produce what you said. I get :7777/pls/apex/f?p=102:9:401723411567861:::::#

and you application gets http://apex.oracle.com/pls/otn/f?p=41715:36:2560338678771080#

Do you know if im doing anything wrong ?

The query for the Emp Details table is:
SELECT EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO
FROM EMP
WHERE EMPNO = :P36_CUR_EMP
AND :P36_CUR_EMP IS NOT NULL
UNION
SELECT TO_NUMBER(NULL)
, TO_CHAR(NULL)
, TO_CHAR(NULL)
, TO_NUMBER(NULL)
, TO_DATE(NULL)
, TO_NUMBER(NULL)
, TO_NUMBER(NULL)
, TO_NUMBER(NULL)
FROM DUAL
WHERE :P36_CUR_EMP IS NULL

The code for the refreshReport function is:
function refreshReport(pValue, pField)
{ // Refresh this region with the new pValue for the pField
// var region=$v('P0_REGION_ID');
var region='R3259408924885046712';
var link='f?p='+ $v('pFlowId') +':'+ $v('pFlowStepId')+':' + $v('pInstance')+ '::::'+ pField+':'+ pValue;
html_PPR_Report_Page( this, region, link );
}

where can i change the CSS .apexir_WORKSHEET_DATA tr:hover?
Roel said…
@Stefan,
There are more options, but you can add an inline STYLE on the page with <STYLE> and </STYLE> in the Page HTML Header.

Refresh selected row(s) in an Interactive Grid

In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid. The use case I'll cover right here is probably more common - and therefore more useful!

Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user.The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even worse) while you…

Dockerize your APEX development environment

Nowadays Docker is everywhere. It is one of the main components of Continuous Integration / Continuous Development environments. That alone indicates Docker has to be seen more as a Software Delivery Platform than as a replacement of a virtual machine.

However ...

If you are running an Oracle database using Docker on your local machine to develop some APEX application, you will probably not move that container is a whole to test and production environments. Because in that case you would not only deliver a new APEX application to the production environment - which is a good thing - but also overwrite the data in production with the data from your development environment. And that won't make your users very excited.
So in this set up you will be using Docker as a replacement of a Virtual Machine and not as a Delivery Platform.
And that's exactly the way Martin is using it as he described in this recent blog post. It is an ideal way to get up and running with an Oracle database …

apex_application.g_f0x array processing in Oracle 12

If you created your own "updatable reports" or your custom version of tabular forms in Oracle Application Express, you'll end up with a query that looks similar to this one:
then you disable the "Escape special characters" property and the result is an updatable multirecord form.
That was easy, right? But now we need to process the changes in the Ename column when the form is submitted, but only if the checkbox is checked. All the columns are submitted as separated arrays, named apex_application.g_f0x - where the "x" is the value of the "p_idx" parameter you specified in the apex_item calls. So we have apex_application.g_f01, g_f02 and g_f03. But then you discover APEX has the oddity that the "checkbox" array only contains values for the checked rows. Thus if you just check "Jones", the length of g_f02 is 1 and it contains only the empno of Jones - while the other two arrays will contain all (14) rows. So for processing y…
