+## How to Add Swimlane Using the AddDiagramElementsAsync Method
+
+The following code example shows how to add a Swimlane and a Connector at runtime using binding properties after the diagram has been initialized, by calling the `AddDiagramElementsAsync` method.

 ## How to Clear Nodes and Connectors from the Diagram
 
 The [Clear](https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.Diagram.SfDiagramComponent.html#Syncfusion_Blazor_Diagram_SfDiagramComponent_Clear) method removes all elements from the diagram, including nodes, connectors, and groups. Use it to reset the canvas to a blank state before loading or creating a new set of elements.

+>Note:If you set a fixed swimlane height and the combined height of the swimlane header and lanes is less than the swimlane’s height, an extra lane is automatically created to fill the remaining space. To avoid this, either remove the fixed swimlane height or ensure the header and lane heights together equal the swimlane height.
