This topic illustrates how to implement the following Gantt objects:
- Tasks
- Dependencies
- Resources
- Resource assignments
public class Task
{
public int Key { get; set; }
public int? ParentKey { get; set; }
public string Title { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public int Progress { get; set; }
public string Color { get; set; }
public Task() { }
public Task(string key, string parentKey, string title, string start, string end, string progress, string color) {
Key = Convert.ToInt32(key);
if (string.IsNullOrEmpty(parentKey))
ParentKey = null;
else
ParentKey = Convert.ToInt32(parentKey);
Title = title;
StartDate = DateTime.Parse(start);
EndDate = DateTime.Parse(end);
Progress = Convert.ToInt32(progress);
Color = color;
}
}
public class Dependency
{
public int Key { get; set; }
public int PredecessorKey { get; set; }
public int SuccessorKey { get; set; }
public int Type { get; set; }
}
public class TaskResource
{
public int Key { get; set; }
public string Name { get; set; }
public string Color { get; set; }
}
public class TaskResourceAssignment
{
public int Key { get; set; }
public int TaskKey { get; set; }
public int ResourceKey { get; set; }
}
The following code allows you to create sample data for the Gantt’s objects (tasks, dependencies, resources):
public static class GanttDataProvider
{
const string
TasksSessionKey = "Tasks",
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() {
var result = new List<Task>();
