I would love to see a feature added to the MVC Gantt control that would allow filtering tasks within the Gantt. Currently when we filter tasks in our Gantt using an external filter which filters the datasource tasks are dropped from the result set if their parent tasks do not meet the filter criteria. This is obviously a problem and makes filtering useless when tasks are dropped when they actually meet the criteria. I would like to see the filtering work as the TreeView and TreeList controls do. When you filter a column in those controls the parent items are returned regardless of whether they meet the filter criteria. This is needed in a hierarchical control like the Gantt chart.

This would be a great addition to the control. In the meantime, we'll either leave filtering out of our application or try to find a way to recursively gather all of the parent task ids and include them in our service to return tasks that meet the filter criteria.

Thanks for considering!
