The linked grids can be shown in tabs, or an accordion control. The ' CustomEvent ' will cause the grid event 'OnExpandRow' to fire. This event sets a number of properties such as e.html and e.javascript. The contents of the expanded row will be set to e.html. If the e.javascript is not null, the javascript contained in this property will be executed. There are other optional properties available to allow a developer to create a custom display that can be linked to the current record.
