Critical Path feature

22 Jul 20222 minutes to read

The critical path in a project is indicated by a single task or a series of tasks. If a task in critical path is delayed, the entire project will be delayed. A task is considered to be critical if any delay to this task would affect the project end date.

The critical path can be enabled in Gantt by using the built-in toolbar button or enableCriticalPath to true.

CSHTML

@Html.EJS().Gantt("Gantt").DataSource((IEnumerable<object>)ViewBag.DataSource).Height("450px").TaskFields(ts => ts.Id("TaskId").Name("TaskName"
 ).StartDate("StartDate").EndDate("EndDate").Duration("Duration").Progress("Progress").Child("SubTasks")
 ).EnableCriticalPath(true).EditSettings(es => es.AllowAdding(true).AllowEditing(true).AllowDeleting(true)
 ).Toolbar(new List<string>() { "CriticalPath" }).Render()

Criticalpath.cs

public IActionResult Index()
{
    ViewBag.DataSource = GanttData.EditingData();	
    return View();
}

 ).QueryTaskbarInfo("queryTaskbarInfo").Render()

 <script>
        function queryTaskbarInfo(args) {
             if ((args.data.isCritical || args.data.slack === '0 day') && !args.data.hasChildRecords) {
                args.taskbarBgColor = 'rgb(242, 210, 189)';
                args.progressBarBgColor = 'rgb(201, 169, 166)';
