Let’s see how to create a swimlane diagram using the Syncfusion Blazor Diagram component!

Brief introduction of swimlane elements

Before diving into the technical details, let’s take a moment to familiarize ourselves with the fundamental Swimlane elements such as header, phases, lanes, and their respective children.

Swimlane header

The swimlane header is key in defining the purpose of swimlanes. The Header property of a swimlane allows you to specify its textual description and customize its appearance.

Phases

The phase represents a subprocess that divides each lane horizontally or vertically, depending on the orientation of the swimlane. Within the swimlane, multiple phases can be incorporated to delineate different stages or subprocesses within the overall workflow.

Lanes

A lane represents a distinct functional unit or department within a business process, facilitating the mapping of activities within the unit itself or between different units.

We can add the required number of lanes to a swimlane and render them in the diagram. The lanes are automatically stacked inside the swimlane based on their order of addition. This ensures a structured representation of the process flow, enhancing clarity and organization within the diagram.

Lane children

To add nodes to a lane, simply include them in the lane’s children collection.  These nodes represent tasks, decisions, events, gateways, milestones, or annotations, organizing the lane’s content for clear visualization of the workflow.

How to create a swimlane diagram using the Blazor Diagram component?

Let’s follow these steps to create a swimlane diagram easily using the Blazor Diagram component:

Step 1: Creating a basic swimlane diagram

We can create a swimlane diagram programmatically or interactively using the symbol palette.

Creating a swimlane is effortless with the shapes from the symbol palette. The Blazor Diagram component supports adding lanes, phases, and other elements to the symbol palette.

The following code example demonstrates how to add swimlane shapes to the symbol palette.

@using Syncfusion.Blazor.Diagram
@using Syncfusion.Blazor.Diagram.SymbolPalette

<div class="control-section">
    <div style="width:20%;">
        <div id="palette-space" class="sb-mobile-palette" style="border: 2px solid #b200ff">
            <SfSymbolPaletteComponent @ref="@symbolpalette" Height="300px" Width="200px"
                                      Palettes="@Palettes" SymbolHeight="60" SymbolWidth="60" SymbolMargin="@SymbolMargin">
            </SfSymbolPaletteComponent>
        </div>
    </div>
</div>

@code
{
    //Reference the symbol preview.
    DiagramSize SymbolPreview;
    //Define symbol margin.
    SymbolMargin SymbolMargin = new SymbolMargin { Left = 15, Right = 15, Top = 15, Bottom = 15 };

    SfSymbolPaletteComponent symbolpalette;

    //Define palette collection.
    DiagramObjectCollection<Palette> Palettes = new DiagramObjectCollection<Palette>();

    // Defines palette's swimlane-shape collection.
    DiagramObjectCollection<NodeBase> SwimlaneNodes = new DiagramObjectCollection<NodeBase>();

    protected override void OnInitialized()
    {
        InitPaletteModel();
    }

    private void InitPaletteModel()
    {
        Palettes = new DiagramObjectCollection<Palette>();

        SwimlaneNodes = new DiagramObjectCollection<NodeBase>();

        //create a horizontal lane.
        Lane horizontalLane = new Lane()
            {
                ID = "HorizontalSwimlane",
                Orientation = Orientation.Horizontal,
                Height = 100,
                Width = 150,
                // Style = new TextStyle() { Fill = "orange", StrokeColor = "black" },
                Header = new SwimlaneHeader()
                {
                    Annotation = new ShapeAnnotation() { Content = "Lane Title" },
                    Style = new TextStyle() { Fill = "lightblue", StrokeColor = "black" },
                    Width = 25,
                    Height = 100
                },
            };

        //create a vertical lane.
        Lane verticalLane = new Lane()
            {
                ID = "VerticalSwimlane",
                Orientation = Orientation.Vertical,
                Height = 150,
                Width = 100,
                // Style = new TextStyle() { Fill = "orange", StrokeColor = "black" },
                Header = new SwimlaneHeader()
                {
                    Annotation = new ShapeAnnotation() { Content = "Lane Title" },
                    Style = new TextStyle() { Fill = "lightblue", StrokeColor = "black" },
                    Width = 100,
                    Height = 25
                },
            };

        //create a horizontal phase.
        Phase horizontalPhase = new Phase() { ID = "HorizontalPhase", Orientation = Orientation.Horizontal, Width = 80, Height = 1, Style = new ShapeStyle() { Fill = "#5b9bd5", StrokeColor = "#5b9bd5" } };

        //create a vertical phase.
        Phase verticalPhase = new Phase() { ID = "VerticalPhase", Orientation = Orientation.Vertical, Width = 1, Height = 80, Style = new ShapeStyle() { Fill = "#5b9bd5", StrokeColor = "#5b9bd5" } };

        SwimlaneNodes = new DiagramObjectCollection<NodeBase>()
        {
            horizontalLane,
            verticalLane,
            horizontalPhase,
            verticalPhase
        };

        Palettes = new DiagramObjectCollection<Palette>()
        {
            new Palette(){Symbols =SwimlaneNodes,Title="Swimlane Shapes",ID="SwimlaneShapes" },
        };
      }
}

To create a swimlane programmatically, you need to define the swimlane object and then add it to the swimlanes collection of the diagram. When a swim lane is created, one lane and one phase are automatically added by default.

The following code example demonstrates how to create a swimlane diagram programmatically.

@using Syncfusion.Blazor.Diagram

<SfDiagramComponent Height="600px" Swimlanes="@SwimlaneCollections" />

@code
{
    //Define the diagram's swimlane collection.
    DiagramObjectCollection<Swimlane> SwimlaneCollections = new DiagramObjectCollection<Swimlane>();

    protected override void OnInitialized()
    {
        // A swimlane is created and stored in the swimlanes collection.
        Swimlane swimlane = new Swimlane()
        {
            OffsetX = 400, OffsetY = 200, Height = 120, Width = 450,
        };
        // Add swimlane.
        SwimlaneCollections.Add(swimlane);
    }
}

Refer to the following image.

Step 2: Adding a lane

We can create a lane and add it to the lanes collection. For the horizontal swimlane, we should set its Height. For the vertical swimlane, we should set its Width. Furthermore, we can customize the lane and its header using the Style property.

The following code example explains how to define and customize a lane and its header.

@using Syncfusion.Blazor.Diagram

<SfDiagramComponent Height="600px" Swimlanes="@SwimlaneCollections" />

@code
{
    // Define the diagram's swimlane collection.
    DiagramObjectCollection<Swimlane> SwimlaneCollections = new DiagramObjectCollection<Swimlane>();

    protected override void OnInitialized()
    {
        // A swimlane is created and stored in the swimlanes collection.
        Swimlane swimlane = new Swimlane()
        {
            Header = new SwimlaneHeader()
            {
                Annotation = new ShapeAnnotation()
                {
                    Content = "SALES PROCESS FLOW CHART"
                },
                Height = 50,
            },
            OffsetX = 400,
            OffsetY = 200,
            Height = 120,
            Width = 450,
            Lanes = new DiagramObjectCollection<Lane>()
            {
                new Lane()
                {
                    Height = 100,
                    Header = new SwimlaneHeader()
                    {
                        Width = 30,
                        Style = new TextStyle()
                        {
                            Fill = "Teal"
                        },
                        Annotation = new ShapeAnnotation()
                        {
                            Content = "Consumer",
                            Style = new TextStyle()
                            {
                                Color = "White",
                                TextDecoration = TextDecoration.Underline,
                                Italic = true,
                                Bold = true
                            }
                        }
                    }
                }
            }
        };

        // Add swimlane.
        SwimlaneCollections.Add(swimlane);
    }
}

Refer to the following image.

Step 3: Adding a phase

You can create a phase and add it to the swimlane phases collection. For a horizontal swimlane, we should set the Width of the phase. For a Vertical swimlane, we should set the Height of the phase. Furthermore, we can customize the phase and its header using the Style property.

The following code example explains how to define and customize a phase and its header.

@using Syncfusion.Blazor.Diagram
<SfDiagramComponent Height="600px" Swimlanes="@SwimlaneCollections" />

@code
{
    //Define the diagram's swimlane collection.
    DiagramObjectCollection<Swimlane> SwimlaneCollections = new DiagramObjectCollection<Swimlane>();

    protected override void OnInitialized()
    {
        // A swimlane is created and stored in the swimlanes collection.
        Swimlane swimlane = new Swimlane()
            {
                Header = new SwimlaneHeader()
                {
                    Annotation = new ShapeAnnotation()
                    {
                        Content = "SALES PROCESS FLOW CHART"
                    },
                    Height = 50,
                },
                OffsetX = 400,
                OffsetY = 200,
                Height = 150,
                Width = 450,
                Phases = new DiagramObjectCollection<Phase>()
                {
                    new Phase()
                    {
                        Width = 450,
                        Header = new SwimlaneHeader()
                        {
                            Annotation = new ShapeAnnotation(){Content = "Phase 1", Style = new TextStyle(){ Color = "White", TextDecoration = TextDecoration.Underline, Italic = true, Bold = true} },
                            Height = 30
                        },
                        Style = new TextStyle(){Fill = "Teal"},
                    }
                }
            };
        // Add swimlane.
        SwimlaneCollections.Add(swimlane);
    }
}

Refer to the following image.

Step 4: Adding nodes into a lane

To add nodes to a lane, we should add a node collection to the lane’s children collection. The node’s LaneOffsetX and LaneOffsetY properties will position the element in the lane canvas. By default, lane children will maintain a 20px padding from the lane canvas.

The following code example explains how to add nodes to a lane.

@using Syncfusion.Blazor.Diagram

<SfDiagramComponent Height="600px" Swimlanes="@SwimlaneCollections" />

@code
{
    //Define the diagram's swimlane collection.
    DiagramObjectCollection<Swimlane> SwimlaneCollections = new DiagramObjectCollection<Swimlane>();

    protected override void OnInitialized()
    {
        // A swimlane is created and stored in the swimlanes collection.
        Swimlane swimlane = new Swimlane()
            {
                Header = new SwimlaneHeader()
                {
                    Annotation = new ShapeAnnotation()
                    {
                        Content = "SALES PROCESS FLOW CHART"
                    },
                    Height = 50,
                },
                OffsetX = 400,
                OffsetY = 200,
                Height = 120,
                Width = 450,
                Lanes = new DiagramObjectCollection<Lane>()
                {
                    new Lane(){Height = 100,
                    Header = new SwimlaneHeader(){
                        Width = 30,
                        Annotation = new ShapeAnnotation(){ Content = "Consumer" }
                    },
                    Children = new DiagramObjectCollection<Node>()
                    {
                        new Node(){Height = 50, Width = 50, LaneOffsetX = 100, LaneOffsetY = 30},
                        new Node(){Height = 50, Width = 50, LaneOffsetX = 250, LaneOffsetY = 30},
                    }
                    },
                }
            };
        // Add swimlane.
        SwimlaneCollections.Add(swimlane);
    }
}
