問候改變，DropDownList的值不是的UpdatePanel和ModalPopupExtender
我有一個modalpopupextender一個asp.net網頁一個UpdatePanel內。當我在彈出框中單擊「確定」時，我可以從彈出窗口中獲取文本框值，但DropDownLists具有舊/默認值，而不是我爲它們選擇的新值。
彈出窗口中的所有控件都設置爲enableviewstate = true，autopostback = false（我只是想點擊ok按鈕而不是每次更改彈出窗口的值時， 。
這裏是相關的代碼。

。 。 。那裏有一個WEBGRID在這裏。 。 。
這種模式的popupextender在這裏受到了重創。我不能得到stackoverflow來顯示它的權利。 雖然它顯示了這裏的屬性。 「 BackgroundCssClass =」 modalBackground」 陰影效果= 「真」 OkControlID = 「btnEditOk」 CancelControlID = 「btnEditCancel」 動畫= 「」>

我遇到了同樣的問題，對我來說，我在ModalPopupExtender中顯示了代碼隱藏中的.Show（）方法，該方法是通過在GridView中單擊按鈕來調用的。它的定義似乎是導致它的原因;例如，如果您嘗試在Page_Load上打開模式彈出窗口，它就會起作用。我會繼續調查，因爲我也需要這項工作，如果我能做到，請留下一個答案。如果你修復它，請保持更新。 – bgs264 2010-04-13 09:13:33
