XamDataGrid與XamComboEditor不保留選擇

我遇到一個XamDataGrid在其中一個字段中承載XamComboBox問題。如果用戶使用鼠標將焦點置於組合框列中，然後使用鍵盤上的字母選擇項目，然後按Tab鍵移至下一列，則組合中的選擇將丟失。XamDataGrid與XamComboEditor不保留選擇

我不確定這是控件中的錯誤還是隻是我使用它們的方式，我試圖通過使用CellDeactivating事件來解決問題，但我認爲該值已經失去了那一點。我正在使用控件的版本11.2.20112.2316。我也發佈了這個到Infragistics forums。

這一點XAML和代碼隱藏證明了這個問題。
