Register the Blazor service

Open the Program.cs file in Blazor WebAssembly App and register the Blazor service.

Program.cs
....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script references in the App.razor file.

App.razor
...
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
...
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

Add Blazor Gantt Chart component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor Gantt Chart component inside the razor file.

Home.razor
@using Syncfusion.Blazor.Gantt

<SfGantt DataSource="@TaskCollection" Height="450px" Width="700px">
    <GanttTaskFields Id="TaskID" Name="TaskName" StartDate="StartDate" EndDate="EndDate" Duration="Duration" Progress="Progress" ParentID="ParentID">
    </GanttTaskFields>
</SfGantt>

@code
{
    private List<TaskData>? TaskCollection { get; set; }
    protected override void OnInitialized()
    {
        this.TaskCollection = GetTaskCollection();
    }

    public class TaskData
    {
        public int TaskID { get; set; }
        public string? TaskName { get; set; }
        public DateTime StartDate { get; set; }
        public DateTime EndDate { get; set; }
        public string? Duration { get; set; }
        public int Progress { get; set; }
        public int? ParentID { get; set; }
    }

    private static List<TaskData> GetTaskCollection()
    {
        List<TaskData> Tasks = new List<TaskData>()
        {
            new TaskData() { TaskID = 1, TaskName = "Project initiation", StartDate = new DateTime(2022, 01, 04), EndDate = new DateTime(2022, 01, 07), },
            new TaskData() { TaskID = 2, TaskName = "Identify Site location", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentID = 1, },
            new TaskData() { TaskID = 3, TaskName = "Perform soil test", StartDate = new DateTime(2022, 01, 04), Duration = "4", Progress = 40, ParentID = 1, },
            new TaskData() { TaskID = 4, TaskName = "Soil test approval", StartDate = new DateTime(2022, 01, 04), Duration = "0", Progress = 30, ParentID = 1, },
            new TaskData() { TaskID = 5, TaskName = "Project estimation", StartDate = new DateTime(2022, 01, 06), EndDate = new DateTime(2022, 01, 10), },
            new TaskData() { TaskID = 6, TaskName = "Develop floor plan for estimation", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 30, ParentID = 5, },
            new TaskData() { TaskID = 7, TaskName = "List materials", StartDate = new DateTime(2022, 01, 06), Duration = "3", Progress = 40, ParentID = 5, },
            new TaskData() { TaskID = 8, TaskName = "Estimation approval", StartDate = new DateTime(2022, 01, 06), Duration = "0", Progress = 30, ParentID = 5, }
