Gantt Chart Light Library for Silverlight™ 4/WPF 4 contains task hierarchy and resource scheduling controls with increased runtime performance, standard DataGrid feature inheritance, data binding support, customizable look and feel, task and dependency drag and drop operations, support for displaying resource groups and spreading conflicting assignments on multiple lines in a single row*, critical path enumeration, baseline visualization, resource leveling, culture awareness, printing and exporting support, undo/redo queue*, two-way Microsoft Project® XML compatibility*, resource allocation load chart output†, PERT chart and network diagram output*†, Model-View-ViewModel (MVVM) pattern based development support (Prism), etc.

The interactive Gantt Chart and Schedule Chart controls within the product may be used to display all types of data that can be presented on a timeline (i.e. their date and time being incremented along the X-axis in a chart area), and can be used to display tasks, appointments, or other programmed activities for short or long periods of time. It is therefore easy to use these components to build project management, resource planning, activity scheduling, item programming, execution planning, equipment rental, location sharing, assembly-line production, and many other related types of applications.

Developers may reference, configure, and optionally extend the components within their applications using any of the .NET programming languages available, including C#, Visual Basic® .NET (VB), and C++/CLI, and any Visual Studio® edition that supports .NET 4+/Silverlight™ 4+.

By purchasing a product license you may use both Silverlight™ and WPF controls.
Furthermore, Silverlight™ components may also be used to develop Web parts within custom SharePoint® based applications.


The current product build is 4.3.3 (see also what's new).

Note:
Gantt Chart Library for WPF 4 is an older related product that includes controls similar to some of the WPF components within this product, but designed to get higher development elegance, customizability, and coercion/validation levels (triggering, however, lower runtime performance).


Using Gantt Chart Light Library software developers can:

  • Display and allow end users to update an (indentation based) hierarchical list of tasks within the GanttChartDataGrid control; grid columns can be fully customized and templated:

    Gantt Chart with data grid

    <pdgcc:GanttChartDataGrid>
        <pdgcc:GanttChartDataGrid.Items>
            <pdgcc:GanttChartItem Content="Task 1"/>
            <pdgcc:GanttChartItem Content="Task 1.1" Indentation="1" Start="[...]" Finish="[...]"
                                  CompletedFinish="[...]" AssignmentsContent="Resource 1"/>
            <pdgcc:GanttChartItem Content="Task 1.2" Indentation="1" Start="[...]" Finish="[...]"
                                  AssignmentsContent="Resource 1, Resource 2" Predecessors="[...]"/>
            <pdgcc:GanttChartItem Content="Task 2" Predecessors="[...]"/>
            <pdgcc:GanttChartItem Content="Task 2.1" Indentation="1" Start="[...]" Finish="[...]"/>
            <pdgcc:GanttChartItem Content="Task 2.2" Indentation="1"/>
            <pdgcc:GanttChartItem Content="Task 2.2.1" Indentation="2" Start="[...]" Finish="[...]"/>
            <pdgcc:GanttChartItem Content="Task 2.2.2" Indentation="2" Start="[...]" IsMilestone="true"
                                  Predecessors="[...]"/>
        </pdgcc:GanttChartDataGrid.Items>
    </pdgcc:GanttChartDataGrid>

  • Fully customize the item appearance, either for the entire chart or for individual entries in the view:

    Gantt Chart with data grid, custom appearance

  • Fully customize the chart scales, zoom level, and the visible and working times of day and week in the view:

    Gantt Chart with data grid, custom schedule

  • Display and allow end users to update the assignable resource list and their task assignments within the ScheduleChartDataGrid control; grid columns can be fully customized and templated:

    Schedule Chart with data grid

  • Display multiple task bar lines within each resource row, such as to avoid overlapping time conflicting assignments:

    Schedule Chart with data grid, multiple lines per row

  • Display groups or hierarchies of resources:

    Schedule Chart with data grid, hierarchy

  • Alternatively, display and/or allow end users to update the task hierarchy and resource scheduling information within simple GanttChartView and ScheduleChartView controls, without attached data grids:

  • Display resource allocation information within the LoadChartView control, either for a single resource item, such as that being currently selected in an external drop down list, or for multiple resource items, within the LoadChartDataGrid control†:

  • Display network diagram and PERT Chart sheets with the NetworkDiagramView and PertChartView controls†:

Provided the flexibility and extensibility of the included components, complex functionality can also be achieved when needed in advanced scenarios, without modifying the original source code of the software (although the source code is available with Business Plus licenses):

  • Fully customize the task bar and shape templates, such as to enable inline task value editing, or presenting work interruptions, multiple bars (e.g. planned vs. actual timing values), supplemental textual information, and timeline bound marker icons in the chart†:

    Gantt Chart with data grid, bar templating

    Network diagram, shape templating

  • Customize the view and include code to generate recurrent tasks:

    Gantt Chart with data grid, recurrence

  • Customize the view and include code to present interactive child task bars in place when summary items are collapsed in the hierarchy:

    Gantt Chart with data grid, summary bars

  • Customize the view and include code to zoom in and generate scales for hours, minutes, or even seconds:

    Gantt Chart with data grid, minute scale

  • Customize the view and include code to present and accept day and week numbers instead of specific date and time values:

    Gantt Chart with data grid, numeric days
