Built for project management

More than just charting: with optional auto-scheduling, PERT based critical path highlighting, resource leveling, baseline bars, and task splitting, you get a complete project management solution in a single app component.

Multiple appearance settings, fully customizable templates

Change colors and other UI details either generally or for individual data items, or define templates for standard, milestone, and summary tasks, and for dependency lines. For example, to support interruptions as shown for some tasks below. Or download and adapt the default styles and templates for Gantt chart and PERT chart components as needed.

Printing, exporting images, Microsoft Project, and Excel®

Call Print method to initiate printing (or PDF exporting) of all grid and chart content at once. Export scalable diagram images that your end users can use for any purpose. Enable saving and loading Microsoft Project XML files using built-in methods of Gantt Chart components. Use Adapter API (free for product licensees) to save and load data from Excel® sheets, too.

Timeline and calendars

Configurable timeline duration and zoom level, visible and working days and hours with fixed or periodic holidays or breaks (possibly different for each item if needed), scale headers with built-in or custom intervals and text formatters, and update interval applying upon dragging items.

Screenshot

Customizable date formats

Date and times are formatted using the current user's culture by default, but you can customize formatting too. For both standard date columns and custom item values that you supplementary need, e.g. to template and show secondary draggable data bound bars in the chart area too.

Grid cell editors

Use either built in or custom grid cell editors and converters. With DataTreeGrid component (available separately) you can easily obtain a hierarchical assignment selector dialog as the one presented below.

Screenshot

Multiple (recurrent) bars/row

Define custom columns and support properties to generate and display multiple chart items for each grid row. Daily, weekly, monthly, or yearly recurrence, with or without series end date: imagination is the only limit.

Screenshot

Schedule Charts

Present items assigned to any resource on a separate row, optionally on multiple lines in case of time conflicts. Allow dragging the bars vertically – from their bottom hoverable area – to set (or remove) their assignments.

Screenshot

Resource hierarchy

With ScheduleChartDataGrid, resources can be displayed in groups (of unlimited indentation levels) as well. Expanding an collapsing groups can help end users tremendously when comparing unrelated schedules.

Load Charts, PERT Charts, Network Diagrams

You can also easily generate other types of diagrams based on Gantt Chart items (or by defining data on the fly.)

  • Recently the idea came to me to add a project management module to an existing WinForms program. Via the NuGet Package Manager I quickly ended up at the DlhSoft libraries. The costs for the license are very acceptable. I am impressed by their good service, speed and patience! DlhSoft is definitely worth a 5 star recommendation!

  • We used DlhSoft's Gantt for a project management software. It was easy to use through its helpful documentation and a lot of free examples. If there was a question, the support team answered quickly with a very competent answer.

  • We've assessed a few other Silverlight Gantt Chart components and DlhSoft [product] … is by far and without a shadow of a doubt several classes above the competition. It is easy and intuitive to use. Properties that you expect to be exposed are just there. …

  • We have used the product for 6 months now and we have been very impressed. The API is intuitive, the documentation is good and above all, the support is fantastic. I have never received so fast responses from anyone before. We have a WinForms app, written in C++/CLI. We host the WPF component inside this and it works great. I can recommend DlhSoft to anyone.

It was used as basis for a project planning tool based on Silverlight and deployed as a SharePoint WebPart, and fulfilled our needs from a functional and technical perspective, meeting also our performance requirements. …
