Question

下面的代码是我绑定的dataTable。我无法弄清楚为什么它只显示顶级节点。

var currentLayer;
var layers = [];

// Create your layers and push them to the layers array.

window.addEventListener("keypress", function(e) {
  var pressedKey = Number(e.key);

  // If button pressed is not a number, return.
  if (isNaN(pressedKey)) return;
  // If the pressed number is greater than the length of layers, return.
  if (pressedKey - 1 >= layers.length) return;
  // If currentLayer is set, remove it from the map.
  if (currentLayer) map.removeLayer(currentLayer);

  currentLayer = layers[pressedKey - 1];
  map.addLayer(currentLayer);
});

- EDIT-- 如果我将它添加到标记中，我可以看到2个节点。但它切换到垂直，不显示其他节点。

                BreadCrumbSiteMap.DataSource = siteMapNavigationLocation;
            BreadCrumbSiteMap.DataBind();
<telerik:RadSiteMap ID="BreadCrumbSiteMap" EnableViewState="true" runat="server"
                                                    DataFieldID="NodeID" DataFieldParentID="ParentNodeid" DataNavigateUrlField="url" DataTextField="NodeName"
                                                    OnNodeDataBound="RadSiteMap1_NodeDataBound"              >
                                    <DefaultLevelSettings ListLayout-RepeatDirection="Horizontal" SeparatorText="/" Layout="Flow" />
                                </telerik:RadSiteMap>

在数据绑定中使用此代码，我可以看到每个节点都绑定并具有降序层次结构。 0,1,2,3

 <LevelSettings>
                                        <telerik:SiteMapLevelSetting Level="0" MaximumNodes="4">
                                        </telerik:SiteMapLevelSetting>
                                    </LevelSettings>

布局=＆＃34;流速＆＃34;停止下面的所有节点渲染...我不得不删除父节点ID，因此它不是分层的。现在它看起来像我想要的面包屑列表..

DataFieldParentID="ParentNodeid"
