The "Apply a Server Side Filter to a Data Collection" Action will apply a server-side filter to a Data Collection when a User clicks to invoke the Action in a Widget. This Action is provided to empower Users to control the data that they are viewing to meet their current needs. The Data Collection that is filtered does not need to be the Data Collection that is driving the selected Widget. Thus, it is possible to click in one Widget and have this Action filter the presentation of other Widgets.

For more information on the concepts of applying Server-side filters to Data Collections in AppBoard, see AppBoard Server-side Queries.

Sample Use Case

Suppose that a particular User will only be concerned with data from a specific location that they select on a map. When the User clicks the location on the map, you can apply a Server-side Filter Action to only return data from that location. Applying the filter on the server side will reduce the amount of data that needs to be passed between the server and client.
