WorkflowView is the design surface which renders a visual representation of process flow described in workflow markup. WorkflowView offers a rich set of user interface functionality needed by the activity designers for rendering and for responding to various Windows-generated events. Also, the WorkflowView offers a set of common functions which can be used by all designers to perform certain activities.

The following code example demonstrates how you can obtain an instance of the WorkflowView class using the GetView method. The code then sets several WorkflowView properties, including HScrollBar and VScrollBar, and calls the FitToScreenSize method.

This code example is part of the Workflow Tracking Profile Designer SDK Sample from the WorkflowDesignerControl.cs file. For more information, see Workflow Tracking Profile Designer.

IDesignerHost designerHost = designSurface.GetService(typeof(IDesignerHost)) as IDesignerHost;
if (designerHost != null && designerHost.RootComponent != null)
    IRootDesigner rootDesigner = designerHost.GetDesigner(designerHost.RootComponent) as IRootDesigner;
    if (rootDesigner != null)

        this.designSurface = designSurface;
        this.loader = loader;
        this.workflowView = rootDesigner.GetView(ViewTechnology.Default) as WorkflowView;
        this.workflowView.Dock = DockStyle.Fill;
        this.workflowView.TabIndex = 1;
        this.workflowView.TabStop = true;
        this.workflowView.HScrollBar.TabStop = false;
        this.workflowView.VScrollBar.TabStop = false;
