	Type serviceType

Examples

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);
}
