Question

我试图在拥有几类森林的森林中打树。

基本结构就是这样:

Root  
 |_
 | Cat A
 |_
 | Cat B
 |_
   Cat C

每个类别必须单独进行可观察的收集。我的大多数类别非常简单。属于这一类的树木配上了书目,没有等级。然而,我确实有一个类别,需要作为特别等级的代表。

以上树木中的“Cat C”形象也一样:

Servers
  |_
  | [SERVER A s DISPLAY NAME]
  |  |_
  |  | Namespaces
  |  |  |_
  |  |_   [NAMESPACE alpha s DISPLAY NAME]
  |  | Deployments
  |  |  |_
  |  |_   [DEPLOYMENT 1 s DISPLAY NAME]
  |_   Configuration File
    [SERVER B s DISPLAY NAME]

基本上,我想的是硬的代号 parent子树,用固定头盔。然后,该项目应收集显示其名称的项目。对于原父母的每个子女,应当有三个固定项目,有动态的儿童清单。

撰写这一文章,我认为这应该是一个非常简单的问题,可以解决。然而,在经过几天后,我无法享有工作等级。下面是我最难得的。 I ve利用“儿童”的综合收集,把姓名空间、部署和编造档案收集到一起。然而,我不能将他们分开。

Mike,

Mixing static and model data probably won t get you where you want. You ll have to create an actual ViewModel that contains the static nodes, etc. I highly recommend Josh Smith s TreeView ViewModel tutorials. This is the first one, but look around for more info. He is one of the most knowledgeable developer on that subject. We had great success following his recommendations.
