html 选择(下拉)控件在asp.net中选择索引更改事件 [英] html select (dropdown) control selected index changed event in asp.net

问题描述

当值更改为要触发的后端方法时，我试图将后端代码放入我的 html 选择控件(下拉列表)，但我找不到该事件.我试过这种方式:

I am trying to put backend code to my html select control (dropdown) when the value is changed a backend method to be triggered, but I Can't find the event. I tried this way:

<select id="ddlCompany" name="select2" onchange="ddlCompany_SelectedIndexChanged" runat="server" class="dropdown nostyle sel1" style="width:100%;" placeholder="Select Company" />

没有任何变化.谁能建议我如何解决这个问题?谢谢，拉齐亚勒

nothing changes. Can anyone advice how I can fix this? Thx, Laziale

推荐答案

尝试使用 SelectedIndexChanged 属性而不是 onchange，如下所示:

Try using the SelectedIndexChanged property instead of onchange, like this:

<select id="ddlCompany" name="select2" OnSelectedIndexChanged="ddlCompany_SelectedIndexChanged" runat="server" class="dropdown nostyle sel1" style="width:100%;" placeholder="Select Company" />
