Swimlane

Swimlane is a type of diagram nodes, which is typically used to visualize the relationship between a business process and the department responsible for it by focusing on the logical relationships between activities.

Create a Swimlane

To create a swimlane, the type of shape should be set as Swimlane. By Default swimlane’s are arranged vertically.

The following code example illustrates how to define a swimlane object.

Headers

Header was the primary element for swimlanes. The Header property of swimlane allows you to define its textual description and to customize its appearance.

The following code example illustrates how to define a swimlane header.

Customization of headers

The height and width of swimlane header can be customized with Weight and Height properties of swimlane header. set fill color of header by using the Style property. The orientation of swimlane can be customized with the Orientation property of the header.

Note: By default the swimlane orientation has Horizontal.

The following code example illustrates how to customise the swimlane header..

Lanes

Lane is a functional unit or a responsible department of a business process that helps to map a process within the functional unit or in between other functional units.

The number of Lanes can be added to swimlane. The lanes are automatically stacked inside swimlane based on the order they are added.

Create an empty lane

  • The lanes Id is used to define the name of the lane and its further used to find the lane at runtime and do any customization.

The following code example illustrates how to define a swimlane with lane.

Create lane header

  • The Header property of lane allows you to textually describe the lane and to customize the appearance of the description.

The following code example illustrates how to define a lane header.

Customizing Lane header

  • The size of lane can be controlled by using the Width and Height properties of the lane.
  • The appearance of the lane can be set by using the Style properties.

The following code example illustrates how to customize the lane header.

@using Syncfusion.Blazor.Diagrams

<SfDiagram Height="500px">
     <DiagramNodes>
          <DiagramNode Width="250" Height="150" OffsetX="400" OffsetY="300" Id="node1">

                    <SwimLaneHeader Height="50">
                         <LaneHeaderAnnotation Content="ONLINE PURCHASE STATUS">

                    </SwimLaneHeader>
                    <DiagramLanes>
                         <DiagramLane Id="lane1" Width="50">
                              <LaneHeader>

                                   <LaneHeaderShapeStyle Fill="red"></LaneHeaderShapeStyle>
                                   <LaneHeaderAnnotation Content="CUSTOMER"></LaneHeaderAnnotation>
                              </LaneHeader>
                         </DiagramLane>

               </DiagramSwimLane>
          </DiagramNode>
     </DiagramNodes>
</SfDiagram>

Phase

Phase are the subprocess which will split each lane as horizontally or vertically based on the swimlane orientation. The multiple number of Phase can be added to swimlane. The following code example illustrates how to add phase at swimlane.

@using Syncfusion.Blazor.Diagrams

<SfDiagram Height="500px">
     <DiagramNodes>
          <DiagramNode Width="250" Height="150" OffsetX="400" OffsetY="300" Id="node1">
          <DiagramSwimLane Type="Shapes.SwimLane">
               <SwimLaneHeader Height="50"></SwimLaneHeader>
               @* Customize the SwimLane phase style *@
               <DiagramPhases>
                    <DiagramPhase Id="phase1" Offset="120"></DiagramPhase>
                    <DiagramPhase Id="phase2" Offset="200"></DiagramPhase>
               </DiagramPhases>
               <DiagramLanes>
                    <DiagramLane Id="lane1" Width="50"></DiagramLane>
               </DiagramLanes>
          </DiagramSwimLane>
          </DiagramNode>
     </DiagramNodes>
</SfDiagram>

Customizing Phase

  • The length of region can be set by using the Offset property of the phase.
  • Every phase region can be textually described with the Header property of the phase
  • You can increase the width of phase by using PhaseSize property of swimlane.

The following code example illustrates how to customize the phase in swimlane.

@using Syncfusion.Blazor.Diagrams

<SfDiagram Height="500px">
     <DiagramNodes>
          <DiagramNode Width="250" Height="150" OffsetX="400" OffsetY="300" Id="node1">
          <DiagramSwimLane Type="Shapes.SwimLane">
               <SwimLaneHeader Height="50"></SwimLaneHeader>
               @* Customize the SwimLane phase style *@
               <DiagramPhases>
                    <DiagramPhase Id="phase1" Offset="120">
                         <PhaseHeader>
                              <PhaseHeaderAnnotation Content="Phase1"></PhaseHeaderAnnotation>
                         </PhaseHeader>
                    </DiagramPhase>
                    <DiagramPhase Id="phase2" Offset="200">
                         <PhaseHeader>
                              <PhaseHeaderAnnotation Content="Phase2"></PhaseHeaderAnnotation>
                         </PhaseHeader>
                    </DiagramPhase>
               </DiagramPhases>
               <DiagramLanes>
                    <DiagramLane Id="lane1" Width="50"></DiagramLane>
               </DiagramLanes>
          </DiagramSwimLane>
          </DiagramNode>
     </DiagramNodes>
</SfDiagram>

Limitations

  • Connectors cannot be cancelled when added directly to swimlane. You must initialize the connector through connector collection.
  • We cannot edit the phase line style.
