WF4.0:如何从活动中获取ActivityDesigner

Question

我使用此代码将CustomDesigner绑定到CustomActivity

AttributeTableBuilder builder = new AttributeTableBuilder();
builder.AddCustomAttributes(typeof(CustomActivity), new DesignerAttribute(typeof(CustomDesigner)));
MetadataStore.AddAttributeTable(builder.CreateTable());

如何从CustomActivity实例获取CustomDesigner实例。

Answer 1

您可以使用视图服务来实现这一点。

designer.Context.Services.GetService<ViewService>().GetView(temp)

temp是流活动设计器的模型项，是WorkflowDesigner
