selectionService = ((IServiceProvider)this.workflowView).GetService(typeof(ISelectionService))
as ISelectionService;
if (selectionService != null)
this.workflowView.EnsureVisible(selectionService.PrimarySelection);
}
Public Sub FindSelection()
Dim selectionService As ISelectionService
selectionService = CType(CType(Me.workflowView, IServiceProvider).GetService(GetType(ISelectionService)), ISelectionService)
If selectionService IsNot Nothing Then
Me.workflowView.EnsureVisible(selectionService.PrimarySelection)
End If
End Sub
