public void FindSelection()
{
ISelectionService selectionService;
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
Remarks
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.
