This topic illustrates how to implement the following Gantt objects:
- tasks
- dependencies
- resources
- resource assignments
public class Task {
public int ID { get; set; }
public int? ParentID { get; set; }
public string Subject { get; set; }
public string Description { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public int PercentComplete { get; set; }
public int Type { get; set; }
public int Status { get; set; }
public string Team { get; set; }
public string Employees { get; set; }
public Task() { }
public Task(string id, string parentid, string subject, string start, string end, string percent, string type, string status, string resources) {
ID = Convert.ToInt32(id);
if(string.IsNullOrEmpty(parentid))
ParentID = null;
else
ParentID = Convert.ToInt32(parentid);
Subject = subject;
StartDate = DateTime.Parse(start);
EndDate = DateTime.Parse(end);
PercentComplete = Convert.ToInt32(percent);
Type = Convert.ToInt32(type);
Status = Convert.ToInt32(status);
Employees = resources;
}
}
public class Dependency {
public int ID { get; set; }
public int ParentID { get; set; }
public int DependentID { get; set; }
public int Type { get; set; }
}
public class TaskResource {
public int ID { get; set; }
public string Name { get; set; }
}
public class TaskResourceAssignment {
public int ID { get; set; }
public int TaskID { get; set; }
public int ResourceID { get; set; }
}
The following code allows you to create sample data for the Gantt’s objects (tasks, dependencies, resources).
public static class GanttDataProvider {

DependenciesSessionKey = "Dependencies",
ResourcesSessionKey = "Resources",
ResourceAssignmentsSessionKey = "ResourceAssignments";
static HttpSessionState Session { get { return HttpContext.Current.Session; } }
public static object GetTasks() { return Tasks; }
public static object GetDependencies() { return Dependencies; }
public static object GetResources() { return Resources; }
public static object GetResourceAssignments() { return ResourceAssignments; }
public static List<Task> Tasks {
get {
if(Session[TasksSessionKey] == null)
Session[TasksSessionKey] = CreateTasks();
return (List<Task>)Session[TasksSessionKey];
}
}
public static List<Dependency> Dependencies {
get {
if(Session[DependenciesSessionKey] == null)
Session[DependenciesSessionKey] = CreateDependencies();
return (List<Dependency>)Session[DependenciesSessionKey];
}
}
public static List<TaskResource> Resources {
get {
if(Session[ResourcesSessionKey] == null)
Session[ResourcesSessionKey] = CreateResources();
return (List<TaskResource>)Session[ResourcesSessionKey];
}
}
public static List<TaskResourceAssignment> ResourceAssignments {
get {
if(Session[ResourceAssignmentsSessionKey] == null)
Session[ResourceAssignmentsSessionKey] = CreateResourceAssignments();
return (List<TaskResourceAssignment>)Session[ResourceAssignmentsSessionKey];
}
}
static List<Task> CreateTasks() {
