我一直有模態彈出窗口這個奇怪的問題。出於某種原因,當我選擇一個下拉項目時,我的更新按鈕不會觸發點擊事件。但隨後我將下拉列表的默認值更新爲更新按鈕。當選擇下拉菜單時,Modalpopup不會關閉
,這裏是我的aspx頁面代碼
<asp:Button ID="Button1" CssClass="hide" runat="server" Text="Button" />

和我的身後爲我更新的代碼(它只是關閉彈出)
Protected Sub cfUpdateBtn_Click(sender As Object, e As EventArgs) Handles cfUpdateBtn.Click
cfPopUp.Hide()
End Sub
對我的生活中,我想不通爲什麼當下拉菜單不是默認值時,更新按鈕將不起作用。
感謝您的幫助球員
你是否運行你的代碼而不使用ajax級聯dropdownlist可能是工作 – 2012-07-09 16:03:38
我不認爲它是級聯下拉列表,我有其他模式彈出窗口級聯下拉,它完美的作品。感謝您看我的問題。 – 2012-07-09 17:40:32
好的,再嘗試一件事,你將你的下拉菜單與Web服務綁定在一起。如果您手動添加項目(意味着硬編碼)到您的下拉菜單仍不起作用? – 2012-07-09 17:49:29
