我正在使用2个DropDownList，1个表之前和之后1个。 这些DropDownList允许设置表内容。 我的问题是，第一个DropDownList工作正常，但第二个的OnSelectedIndexChanged事件不会触发。

工作的是ddlSemaine，ddlSemaine2是破碎的。
我已经尝试将ddlSemaine移到ddlSemaine2后面并停止工作。我还尝试在ddlSemaine2旁边移动ddlSemaine，两者都在工作......
要更具体地说明问题，当我第一次使用ddlSemaine2时，它不会触发OnSelectedIndexChanged并加载没有tblProjet和tblProjet2的网页。但是在这个“空”页面上，如果我重用ddlSemaine2，它可以正常工作并加载正确的内容。最后，如果我再次使用它，它就不起作用。
我认为问题出在Page_Load方法中，但我找不到。
问题是，我需要它是DropDownList，我无法理解发生了什么，所以我想得到一些帮助。
