I want to create a detail page for WorkOrder in Hansen8 with a Grid to bind with and display activity milestones (list collection).

Event: On selection of a work order based on the work order number it should filter the activity and its milestones(list collection) and bind with the Grid in a detail page.

 

I need help in binding a grid with list/collection with this activity milestones list..
