Quick Start Example

Here's a minimal Kanban implementation with data binding:

// Controller action
public ActionResult Index()
{
    ViewBag.data = GetKanbanData();
    return View();
}

private List<KanbanDataModel> GetKanbanData()
{
    return new List<KanbanDataModel>
    {
        new KanbanDataModel { Id = 1, Status = "Open", Summary = "Task 1", Assignee = "Nancy" },
        new KanbanDataModel { Id = 2, Status = "InProgress", Summary = "Task 2", Assignee = "Andrew" },
        new KanbanDataModel { Id = 3, Status = "Testing", Summary = "Task 3", Assignee = "Janet" },
        new KanbanDataModel { Id = 4, Status = "Close", Summary = "Task 4", Assignee = "Nancy" }
    };
}

public class KanbanDataModel
{
    public int Id { get; set; }
    public string Status { get; set; }
    public string Summary { get; set; }
    public string Assignee { get; set; }
}

@* View (Index.cshtml) *@
@(Html.EJS().Kanban("kanban")
    .KeyField("Status")
    .DataSource((IEnumerable<object>)ViewBag.data)
    .Columns(col =>
    {
        col.HeaderText("To Do").KeyField("Open").Add();
        col.HeaderText("In Progress").KeyField("InProgress").Add();
        col.HeaderText("Testing").KeyField("Testing").Add();
        col.HeaderText("Done").KeyField("Close").Add();
    })
    .CardSettings(card =>
    {
        card.ContentField("Summary").HeaderField("Id");
    })
    .Render()
)

Common Patterns

Pattern 1: Kanban with Swimlane Grouping

Group cards by assignee or any field:

@(Html.EJS().Kanban("kanban")
    .KeyField("Status")
    .DataSource((IEnumerable<object>)ViewBag.data)
    .Columns(col =>
    {
        col.HeaderText("To Do").KeyField("Open").Add();
        col.HeaderText("In Progress").KeyField("InProgress").Add();
        col.HeaderText("Testing").KeyField("Testing").Add();
        col.HeaderText("Done").KeyField("Close").Add();
    })
    .CardSettings(card =>
    {
        card.ContentField("Summary").HeaderField("Id");
    })
    .SwimlaneSettings(swim =>
    {
        swim.KeyField("Assignee").TextField("AssigneeName");
    })
    .Render()
)

Pattern 2: Remote Data with OData Service

@(Html.EJS().Kanban("kanban")
    .KeyField("Status")
    .AllowDragAndDrop(false)
    .DataSource(dataMgr =>
    {
        dataMgr.Url("https://services.syncfusion.com/aspnet/production/api/Kanban")
               .CrossDomain(true)
               .Adaptor("ODataAdaptor");
    })
    .Columns(col =>
    {
        col.HeaderText("To Do").KeyField("Open").Add();
        col.HeaderText("In Progress").KeyField("InProgress").Add();
        col.HeaderText("Testing").KeyField("Testing").Add();
        col.HeaderText("Done").KeyField("Close").Add();
    })
    .CardSettings(card =>
    {
        card.ContentField("Summary").HeaderField("Id");
    })
    .DialogOpen("onDialogOpen")
    .Render()
)

<script>
    function onDialogOpen(args) {
        args.cancel = true; // Prevent editing for remote read-only data
    }
</script>

Pattern 3: Custom Card Template

<script id="cardTemplate" type="text/x-jsrender">
    <div class='card-template'>
        <div class='card-header'>${Id} - ${Status}</div>
        <div class='card-content'>
            <div>${Summary}</div>
            <div class='card-footer'>Assigned to: ${Assignee}</div>
        </div>
    </div>
</script>

@(Html.EJS().Kanban("kanban")
    .KeyField("Status")
    .DataSource((IEnumerable<object>)ViewBag.data)
    .Columns(col =>
    {
        col.HeaderText("To Do").KeyField("Open").Add();
        col.HeaderText("Done").KeyField("Close").Add();
    })
    .CardSettings(card =>
    {
        card.HeaderField("Id").Template("#cardTemplate");
    })
    .Render()
)

Pattern 4: Programmatic Card Management

@Html.EJS().Button("addBtn").Content("Add Card").Render()
@Html.EJS().Button("updateBtn").Content("Update Card").Render()
@Html.EJS().Button("deleteBtn").Content("Delete Card").Render()

@(Html.EJS().Kanban("kanban")
    .KeyField("Status")
    .DataSource((IEnumerable<object>)ViewBag.data)
    .Columns(col =>
    {
        col.HeaderText("To Do").KeyField("Open").Add();
        col.HeaderText("Done").KeyField("Close").Add();
    })
    .CardSettings(card =>
    {
        card.ContentField("Summary").HeaderField("Id");
    })
    .Render()
)

<script>
    document.getElementById('addBtn').addEventListener('click', function() {
        var kanbanObj = document.getElementById('kanban').ej2_instances[0];
        kanbanObj.addCard({ Id: 5, Status: 'Open', Summary: 'New Task', Assignee: 'John' });
    });
    
    document.getElementById('updateBtn').addEventListener('click', function() {
        var kanbanObj = document.getElementById('kanban').ej2_instances[0];
        kanbanObj.updateCard({ Id: 5, Status: 'Close', Summary: 'Updated Task', Assignee: 'John' });
    });
    
    document.getElementById('deleteBtn').addEventListener('click', function() {
        var kanbanObj = document.getElementById('kanban').ej2_instances[0];
        kanbanObj.deleteCard(5);
    });
</script>

Pattern 5: Stacked Headers for Column Grouping

Group multiple columns under common parent headers:

@(Html.EJS().Kanban("kanban")
    .KeyField("Status")
    .DataSource((IEnumerable<object>)ViewBag.data)
    .Columns(col =>
    {
        col.HeaderText("To Do").KeyField("Open").Add();
        col.HeaderText("In Progress").KeyField("InProgress").Add();
        col.HeaderText("Testing").KeyField("Testing").Add();
        col.HeaderText("Done").KeyField("Close").Add();
    })
    .StackedHeaders(stack =>
    {
        stack.Text("Planning").KeyFields("Open").Add();
        stack.Text("Development").KeyFields("InProgress,Testing").Add();
        stack.Text("Completed").KeyFields("Close").Add();
    })
    .CardSettings(card =>
    {
        card.ContentField("Summary").HeaderField("Id");
    })
    .Render()
)

Note: KeyFields accepts a comma-separated string of column keys (e.g., "Open,InProgress"), not an array.

Key Properties

Essential Configuration:

• KeyField (string, required): Maps to the data field that determines column placement. Example: "Status"
• DataSource (object, required): Binds data (local array, DataManager, or remote service)
• Columns (List, required): Defines workflow columns with KeyField, HeaderText, and options
• CardSettings.HeaderField (string, required): Unique identifier field for cards (e.g., "Id")
• CardSettings.ContentField (string): Field to display as card content

Common Properties:

• AllowDragAndDrop (bool, default: true): Enable/disable card drag-and-drop
• SwimlaneSettings.KeyField (string): Group cards into horizontal swimlanes
• CardSettings.Template (string): Custom HTML template for card rendering
• DialogSettings.Fields: Configure dialog form fields for Add/Edit operations
• SortSettings: Control card ordering (Index, DataSourceOrder, Custom)
• Height / Width (string): Set dimensions ("100%", "500px", "auto")
• EnableTooltip (bool): Show tooltips on card hover
• EnableVirtualization (bool): Optimize performance for large datasets
• EnablePersistence (bool): Save state across page reloads

Advanced Properties:

• ExternalDropId (string[]): Enable drag-and-drop between Kanban instances or external components
• ConstraintType: Validation type (Column or Swimlane)
• ShowEmptyColumn (bool): Display columns with no cards
• AllowColumnDragAndDrop (bool): Enable column reordering
• StackedHeaders: Group multiple columns under common headers

Best Practices

1. Always define KeyField: It's mandatory for rendering columns and routing cards
2. Use unique HeaderField: Prevents card duplication and enables proper CRUD operations
3. Start with local data: Test functionality before implementing remote data binding
4. Leverage events: Use ActionBegin/ActionComplete for custom validation or logging
5. Optimize with virtualization: Enable for datasets with 100+ cards
6. Implement error handling: Use ActionFailure event for remote data error management
7. Test responsiveness: Verify mobile experience with responsive mode
8. Consider accessibility: Enable keyboard navigation and test with screen readers
