Did not see the solved myself button before
This never fails once I post a question I've been researching for days I will stummble across and answer. Just had to add the .id property to the below code. Sorry about that.
var tab = $find("WebTab1");
var gridId = tab.getTabAt(1).findChild("wdgViews").id;
var grid = $find(gridId);
// Get active row
var activeRow = grid.get_behaviors().get_activation().get_activeCell().get_row()
