在這段代碼中，我們有一個下拉組合框供用戶選擇顯示數據的狀態。在某些情況下，它不會令人耳目一新 - 我如何在這裏添加一個簡單的刷新？在這些地方的情況下啓動：如何刷新下拉並不總是刷新數據？

這裏是實現INotifyPropertyChanged，並具有用於裝載組合框

謝謝你，雷切爾，你可能會專門爲我的代碼編寫代碼，我沒有得到它。 – Booksman
@Booksman你可以將實際加載項目的代碼發佈到你的ComboBox中嗎？我沒有看到你現在發佈的內容。 – Rachel
是的，這裏你有這個選項卡的幾個文件，它可能會更快http://www.mediafire.com/download.php?o2mq15e22iu3cvc現在我會發布以及我們在這裏我們有代碼爲cb的負載。 – Booksman
