Hi Nathan, there are a couple of things you must do.
1) In your dashboard, settings: Create a url "feature" parameter, give it a name (e.g. eventid) and point it to the unique id in your layer (e.g. Event Id). Specify that the map should zoom to when this parameter is being passed in
2) In ExB: use the embed widget to embed your dashboard, connect it to the data that holds the event id and then specify the url to your dashboard separated by an # - use the little database icon at the bottom to include the field (don't just type it)
3) Also in ExB: Somehow set the selected framework item, e.g. through a list widget that lists all the items (in my case earthquakes, same layer that your embed widget is connected to). When user clicks on a list item, your embed widget will pass the correct url parameter to the dashboard.
PS: if your dashboard is on another page within ExB then you must specify a message action that notifies the framework that a data record has been selected. In that way the selected item is known to the "framework" and carried over to the other pages. Don't forget to specify the action data!!!
