In my app, I have a table of talks given in my organization. I would like to have buttons that determine how the various talks (rows) of the table (tab) are shown: One button causes all rows of talks to be shown grouped by the type of talk (each has a category). Another button causes only rows of talks given prior to today (i.e., in the past) to be shown in reverse date order. The third button causes only rows of talks given after today (i.e., scheduled for the future) to be shown in forward date order.
My first approach was to define three tabs, one for each order. This causes three tab icons (all, past, future) to appear in the tab line of the app. What I need are actions to change the settings (order and filter) for the single talks tab to these three states. Any ideas on how I should do this? Thanks.
