Adding tooltips to your APEX report

There are a number of ways to publish tooltips in your application, many of them much more verbose than they need to be.

Some of them implement fairly fancy JavaScript and CSS, but there is a simple way to plug in the default tooltip behaviour into your Apex reports.

When you edit your report column attributes, add the following code into the HTML expression.

<span title="#MY_TOOLTIP_COLUMN#">#MY_COLUMN#</span>

These attributes typically have decent help in regard to the sort of coding examples you can apply.

So this setup places the data from the selected column my_tooltip_column, and displays the value in my_column as you'd normally expect.

And is the display from Google Chrome:

Simple but effective - and flexible.
