One of the best functionalities of the Interactive Grid is declarative master-detail option. That's the reason why I like to use them also in readonly mode. Most of the time I don't need toolbar in detail regions so I turn it off (Region Attributes > Toolbar > Show = No).

But, currently (in APEX 5.1.4.00.04 and less) there's little bug that I can't ignore. It's 9px blank div above report headers:



At first I thought that's easy - I'll just use :empty CSS pseudo selector and hide DIV element with CSS class .a-IG-header:

.a-IG-header:empty{
display:none
}
But that breaks sticky headers when you scroll down. To fix that I had to use different CSS:

.a-IG-header:empty{
padding:0;
border-bottom:0
}
If you want to use other regions for master-detail pages take a look at my plugin on apex.world.

Demo is available here.
Tested on apex.oracle.com (v5.1.4.00.04).
Enjoy!

I saw this at the presentation from Patrick Wolf (I believe somewhere in 2016.). You may already know this but today it took me some time to remember how it works.

There's an easy way to make your forms look nicer by using declarative option to display pre/post item property values as a part of an item (Display as Block). You can display icons, text or links there.





How ToTo enable this, go to the Template Options of the item and set property Item Pre/Post Text to Display as Block:




After that, put the following HTML code in Pre/Post Text item property (in this case it displays Euro currency icon):



You can use any of the icons from Font APEX library there.

Note
In version 5.1.3.00.5 there's a CSS bug with icon alignment. You can fix this by adding following CSS (preferable to global CSS file or Theme Roller):

.t-Form-itemText .fa {
  vertical-align:middle;
  top:-1px;
}

Demo is available here.

Enjoy!

Probably somebody did blog about it but I haven't found it yet.

The Problem
If you didn't modified your Universal theme, by default, success and validation messages appear in the top right corner of a page and you have to close them manually or they disappear when you refresh/submit your page.

It can be confusing when you are on a page with Interactive Grid and you change something repeatedly and successfully - it seems like nothing happened.

The Solution
It can be done by using theme hooks under apex.message namespace.

How To
If you want that all your client side messages are hidden after 3 seconds you should call this code:
apex.message.setThemeHooks({
beforeShow: function(pMsgType, pElement$){
setTimeout(function() {
$('.t-Alert').fadeOut('slow');
}, 3000);
}
});
Where second parameter in setTimeout function (with value 3000) is number of milliseconds. In my case it's 3 seconds.

If you want to hide only success or error/validation messages you can use pMsgType variable. For example:

apex.message.setThemeHooks({
beforeShow: function(pMsgType, pElement$){
if (pMsgType=='success'){
setTimeout(function() {
$('.t-Alert').fadeOut('slow');
}, 3000);
}
}
});
For error/validation messages pMsgType parameter equals error.

To apply this code for all pages in application put this in Page Load dynamic action on global page (page 0) or in your custom JS file (preferred).

Enjoy!

The ProblemIf you use Interactive Reports and Grids you may know that there's a property Fixed To that fixes the report's column headers to the top of the page or region so that the column headers remain visible as the user vertically scrolls the report. But there's no such option for Classic report regions or your custom HTML tables.

The Solution
You can easily do it by using two JS widgets that are build into APEX - Sticky Table Header and Sticky Widget.

How To 
To add it to the Classic report region you have to create After Refresh dynamic action that fires after refresh of your Classic report region:


and define true action that executes the following JavaScript code:

var vRegion$ = $(this.triggeringElement);
vRegion$.setTableHeadersAsFixed();
vRegion$.find('.js-stickyTableHeader').stickyWidget();
Dynamic action should look like this:



Remember to set property Fire on Initialization to Yes.

For the additional options you can check out the file libraries/apex/widget.stickyWidget.js in APEX installation folder or through page source view when you're running your application in debug mode.

For custom HTML tables you can use the same principle and if your custom HTML table is not rendering dynamically fire the JS code above only on page load.

The demo is avaliable here.
Enjoy!

One of the questions that I get constantly is how to make a number format masks live - to format number fields as you type or when you leave an item.

In APEX you can define a number format masks in property Format Mask of number fields:


But it's only affected on page load and after page submit for validating format. There's nothing that prevents end user to enter a string or a number in wrong format.




There's a great JS library for that - autoNumeric.js. So let's see how can you implement it in your apps.


2) Unzip the file and upload autoNumeric.min.js (from dist folder) to your workspace (or application) files (Shared Components > Static Workspace/Application Files) or to your server file location.


3) Add reference to the file in your application. I usually do it under the Shared Components > User Interface Attributes > Desktop > JavaScript File URLs


Now you can use it in your APEX apps. To use it for all APEX number type items you can create onLoad dynamic action on the global page (in most apps this is page 0). Number type items have CSS class number_field so you can initialize AutoNumeric on it, for example:


To explicitly override defaults from the global page you can create onLoad dynamic action on the specific page (remember to put greater sequence id from the one on the page 0) and use the update method to change the default properties:


For other methods and properties see autoNumeric.js documentation.

You can see demo here.

Enjoy!
