Drag assignment bars among resources in Schedule Charts

We are often asked how can an end user drag and drop task assignment bars among resource rows (i.e. vertically) within our Schedule Chart components (such as ScheduleChartResourceListView or lighter ScheduleChartDataGrid, and recently also ASP .NET or HTML5 based ScheduleChartView controls, or within Project Manager application).

In order to avoid mixing horizontal and vertical drag operations which could lead to unwanted behavior at end user level, all our Schedule Chart components are designed to include two separate thumbs – one for horizontal dragging, covering the task bar, and one for vertical dragging, showing up on hovering the task bar, as a dotted underline for the task bar.

Therefore, to drag and drop task assignment bars among resource rows in DlhSoft Schedule Chart controls (from Gantt Chart Light Library for Silverlight/WPF, Gantt Chart Web Library for ASP .NET, Gantt Chart Hyper Library for HTML5, Gantt Chart Library for WPF, Project Management Library for WPF, or Project Manager application) at runtime, you need to:

  • Hover the assignment task bar that you want to move; a dotted line will be displayed at the bottom of the task bar;
  • Move the task bar to a different resource row (i.e. vertically) by clicking and dragging the dotted line.


A small video showing how to do it in a visual manner is available and included in product documentation for your reference.
