# .NET C# Winforms Gantt Chart Control

This .NET class library project provides a C# Winforms UserControl that draws a gantt chart using native GDI+.

## Getting Started

The project is written with Microsoft Visual Studio 2017, simply download the latest source code from the master branch and build the library with the IDE.

### Prerequisites

No pre-requisites other than the .NET Framework.

### Installing

The project builds into a class library with example applications.

## Running the tests

The source code includes a test project GanttChartTests which you can load and run within Microsoft Visual Studio 2017 from the test menu.

## Features

* Support time units Weeks, Days (default), Hours out-of-the-box, can be modified to support other time resolutions.

* Single tasks, grouped tasks, precedent/dependant tasks, split tasks, tagged resources 

* Printing respects page margin, orientation and multiple pages per page

* Percentage complete property for each task

* Various mouse events for customising UI experience directly on the chart.

* Comes with default mouse commands that can be overridden through inheritance.

* Determines critical path and slack

## Basic Usage

### Create Chart and Adding Tasks

	public Form1()

	{

	    InitializeComponents();

	    var manager = new ProjectManager();

	    var task = new Task() { Name = "Hello World" };

	    manager.Add(task);

	    var chart = new Chart();

	    chart.Init(manage);

	    

	    this.Controls.Add(chart);

	    this.AutoScroll = true; // this is no longer required

	}

### Common Task Manipulation

You can manipulate the task through code using various methods in the ProjectManager:

	// Set task durations

	_mManager.SetDuration(wake, 3);

	// Give the Tasks some organisation, setting group and

	// precedents e.g. make "wake" task a subtask under "work"

	_mManager.Group(work, wake);

	// Setting task dependencies e.g. make "wake" task a precedent of "brush teeth" task

	_mManager.Relate(wake, teeth);

	// Assigning Resources e.g. add "jake" resource to "wake" task

	_mManager.Assign(wake, jake);

	// splitting a tasks e.g. split the "pack up" task into 2 new tasks

	_mManager.Split(pack, new MyTask(_mManager), new MyTask(_mManager), 2);

	// set some tooltips to show the resources in each task

	// e.g. set a tooltip on the "wake" task

	_mChart.SetToolTip(wake, string.Join(", ", _mManager.ResourcesOf(wake).Select(x => (x as MyResource).Name)));

### Custom Task Data: Different colors for every tasks

You can change the default task appearance for all task, or as in here change individual task color as a demo for adding custom business data to tasks.

	public partial class ExampleSimple : Form

	{

	  ProjectManager _mProject;

	  public ExampleSimple()

	  {

	    InitializeComponent();

	    _mProject = new ProjectManager();

	    _mProject.Add(new Task() { Name = "New Task" });

	    _mProject.Add(new ColoredTask() { Name = "Purple Task", Color = Color.Purple });

	    _mProject.Add(new ColoredTask() { Name = "Gold Task", Color = Color.Gold });

	    _mChart.Init(_mProject);

	    // Custom behavior on paint task

	    _mChart.PaintTask += (s, e) =>

	    {

	        ColoredTask ctask = e.Task as ColoredTask;

	        if (ctask != null)

	        {

	            var format = new TaskFormat();

	            format = e.Format;

	            format.BackFill = new SolidBrush(ctask.Color);

	            e.Format = format;

	        }

	    };

			

	    // Grab custom data for tasks

	    _mChart.TaskSelected += (s, e) =>

	    {

	        ColoredTask ctask = e.Task as ColoredTask;

	        if (ctask != null)

	        {

	            MessageBox.Show("Selected " + ctask.Color.ToString());

	        }

	    };

	  }

	}

	// Custom task with business data

	public class ColoredTask : Task

	{

	    public ColoredTask() : base() {}

	    public Color Color { get; set; }

	}
