我和西蒙在this post有同樣的問題。Ajax重排序列表不能拖動
他發現了某種解決方案,但它不適用於我。請,有人能解釋我在這個答案中發生了什麼,或者給我建議一些其他的東西。
PS:有一個example on the asp.net site不完全一樣的方式工作,我的重新排序列表...(點擊查看演示)
是這裏建議增加這幾行到web.config中的解決方案:
<httpHandlers>
<add path="ScriptResource.axd" verb="GET,HEAD" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</httpHandlers>
也許我只是需要改變一些東西,使其工作......但我不知道是什麼。例如,我不知道ScriptResource.axd應該是什麼。

代碼中,我的數據加載到從Page_Load事件列表集合,但工作正常。數據綁定也適用。問題在於項目無法重新排序 - 在重新排序期間,排序值不會更改,列表不會更新。
