How to get the filter value "All" if set in the filters

Question

Hello All,

I am trying to save the filters in my application for further processing, I have a filter for example with following values "All", "Texas", "Colorado", "Arkansas".

I am trying to find if the user has modified any filter and only save the filters which user has changed. When i use getAppliedValues i am only getting the values "Texas", "Colorado", "Arkansas". How do i also get the string "All" back if its set.

Have been trying to check API for ways to access it but have not found one. Any help on this would be great. Many Thanks.

Hi All,

For someone who will land on this post, We recently upgraded the tableau server version to 2019.3.1 and see that the the JS API has a new method introduced called 'getIsAllSelected', which returns a boolean value based on if All is set on the filter or not.

At the time of writing this the official documentation does not have a reference to it, but I am sure it would be added soon.

Thanks.

Hi Akshar,   There's 2 ways I can think of to achieve this, the first one is Josh Milligan's default values technique.   Another method I've had success with is to pass it a rubbish value like 1:1 over a parameter filter, and Tableau throws an error and shows you everything.   Step 1  - create State Parameter, note the value All with the Display As title of 'Australia'   Step 2  - create calculated field - note the value 1=1 for Australia   Step 3  - build your viz and expose parameter control   What occurs is when each state and territory is selected, the calculated field will select it and highlight it. When Australia is selected, Tableau defaults to 'nothing is selected' mode, and displays everything.   HTH   Peter
