Use EnsureVisible when you are working with an object in the workflow that requires user interface cues. EnsureVisible will expand parent objects and scroll the WorkflowView as necessary to make the object visible on the designer.

The following example uses the GetService method of the WorkflowView object to return an ISelectionService interface. If the service exists, EnsureVisible is called passing the currently selected activity using the PrimarySelection property of the ISelectionService object.

public void FindSelection()
{
    ISelectionService selectionService;
    selectionService = ((IServiceProvider)this.workflowView).GetService(typeof(ISelectionService))
        as ISelectionService;

    if( selectionService != null )
        this.workflowView.EnsureVisible(selectionService.PrimarySelection);
}
