屬性值

型別：System.Boolean
如果 ContextNode 在資料 Proxy 程序期間包含部分資料，則為 true，如果已加入全部資料，則為 false。

備註

在內容節點樹狀目錄中建立 ContextNode 物件時，您可以在提供所有資訊之前，使用這個屬性做為資料 Proxy。這個屬性表示是否已填入所有資料。

範例

下列範例是來自範例程式碼的 PopulateNode 方法，它會使用 [System.Windows.Controls.TreeView] 做為文件模型，以顯示如何使用資料 Proxy 儲存和載入 InkAnalyzer 的內容節點樹狀目錄。DocumentNodeData 類別會在每個 TreeViewItem 物件的 [System.Windows.FrameworkElement.Tag] 屬性都設定為 DocumentNodeData 物件時，將 ContextNode 資料儲存在文件模型中。

PopulateNode 方法會使用 ContextNode 物件和 InkAnalyzer 物件，透過加入筆劃、屬性資料、註釋型別、子節點和連結完整地填入內容節點。資料來自 DocumentNodeData 物件，而該物件是從對應的 TreeViewItem 取得。

• this[analyzerNode.Id] 是文件模型類別上的索引子，會將 Guid 對應至 TreeViewItem。

• AddLinksToAnalyer 是文件模型類別上的方法，會將連結加入至 ContextNode。

完整填入節點之後，PartiallyPopulated 屬性會設定為 false。
