如何在重新托管的 WF Designer 中跟踪 Windows Workflow 4？
我需要显示工作流程的当前状态。为此，我开发了一个程序，它重新托管工作流程设计器并显示我的工作流程。好的——这是最简单的部分。
接下来，我需要防止工作流程中的任何编辑。我找到了以下解决方案，效果完美：
var readOnlyState = WorkflowDesigner.Context.Items.GetValue<ReadOnlyState>();
if (readOnlyState != null)
readOnlyState.IsReadOnly = true;
但是如何直观地跟踪我的工作流程？我还需要使用额外的元信息（例如它们当前的状态或计数）来丰富/增强所有活动。
有谁知道如何插入叠加层或任何其他类型的视觉元素来显示活动的附加信息？
谢谢

I need to show the current state of a workflow. For that purpose I have developed a programm which is rehosting the Workflow Designer and show my workflow. Ok - that was the easy part.
Next, I need to prevent any editing in the workflow. I found the following solution for that, which work perfect:
var readOnlyState = WorkflowDesigner.Context.Items.GetValue<ReadOnlyState>();
if (readOnlyState != null)
readOnlyState.IsReadOnly = true;
But how do I visually trace my workflow? And I also need to enrich/augment all activities with additional meta information (like their current status or a count).
Has anyone an idea how I could insert an overlay or any other kind of visual element to show additional information for an activity?
Thanks
