detected <select all> item selected

[Oliver]

Hi all,

Is there any way of knowing when the <select all> item is selected from a dropdown.

Reason being, I was task to display a certain note when the <select all> item is selected otherwise it will display a different note on the report.

 

Any help will be much appreciated

Hello Oliver,

First you need to add a data item to the report (e.g. List) and set its data source to the report parameter's data source. Inside this item retrieve all of the data source records and test if they match with the selected values of the report parameter. This test can be performed using an expression with built-in functions or with a custom user function.
The approach using built-in functions is demonstrated in the attached sample report.
