我有一個集合，我在ListView中表示它，並且它由具有擴展器的OrderID分組。在分組時將數據持久化到集合
在Expander Header中，我顯示OrderID以及發票文本框。 在實際的ListView.View中，我顯示了CustomerName，OrderID和一個Invoice TextBox。 因此，每行數據都有自己的發票文本框，每個分組標題都有一個發票文本框。
當我將一個值輸入到組頭文件發票文本框中時，它會自動更新它的成員發票文本框。但是單個行不會更新分組發票文本框。
由於可以從圖像中可以看出（這說明它好多了）
現在當上了「過程所選項目」按鈕，用戶點擊我希望能夠有集合更新與文本框中的InvoiceID。所以不知何故，我需要將分組的行連接到集合以及GroupHeader行。 這可能嗎？

我知道這是很長，但我已經盡力提供儘可能多信息儘可能。 任何幫助將是偉大的，或任何指針在正確的方向。 如果有任何信息我錯過了，大聲呼喊。
