I was asked how to hide/show a column via a radio button in a classic report in Apex.
In order to do this you need a dynamic action triggered on change of the radio group, and a small change to the report template.
First, identify the column you wish to hide. For example empno.
Create a radio group with two buttons (P10_HIDE_SHOW), with values “hide” and “show”. Select “None” for the Page Action when Value Changed.
Create a dynamic action on the radio group (Hide Show Empno):
The dynamic action has to do two things: hide the column heading, then the column values. In order to hide the report column values we need to change the report template and add a rel attribute to all the column values.
That’s it. The radio button should now hide/show the empno column.
You can see a demo on my apex.oracle.com page.
