7 Jul 20221 minute to read

Datasource is used to store or access data associated with a business process. To create a datasource, set the shape to DataSource. The following code example explains how to create a datasource.

@using Syncfusion.Blazor.Diagram

@* Initialize Diagram *@
<SfDiagramComponent Height="600px" Nodes="@nodes"/>

@code
{
    // Initialize the node collection with node.
    DiagramObjectCollection<Node> nodes;

    protected override void OnInitialized()
    {
        nodes = new DiagramObjectCollection<Node>();
        Node node = new Node()
        {
            // Position of the node.
            OffsetX = 100,
            OffsetY = 100,
            // Size of the node.
            Width = 100,
            Height = 100,
            // Unique Id of the node.
            ID = "node1",
            // Sets type to Bpmn and shape to DataSource.
            Shape = new BpmnShape()
            {
                Type = NodeShapes.Bpmn,
                Shape = BpmnShapes.DataSource,
            }
        };
        nodes.Add(node);
    }
}
