c# - 无法单击列表项内的标签

Question

当单击列表项和单选按钮列表中的标签时，selectedIndexChanged 事件不起作用，即使单选按钮列表未被禁用也是如此。

这是代码:

<asp:Label ID="rank" runat="server" class="starss"> 
  <asp:RadioButtonList OnSelectedIndexChanged ="SaveRating" AutoPostBack="true" CssClass="star-rating" ID="RadioButtonList1" runat="server"> 
    <asp:ListItem id="star1" Value=1 runat="server" ><Label for="star1" title="1 stars" ><i class="active fa fa-star" aria-hidden="true"></i></Label></asp:ListItem> 
    <asp:ListItem id="star2" Value=2 runat="server" ><Label for="star2" title="2 stars" ><i class="active fa fa-star" aria-hidden="true"></i></Label></asp:ListItem> 
    <asp:ListItem id="star3" Value=3 runat="server" ><Label for="star3" title="3 stars" ><i class="active fa fa-star" aria-hidden="true"></i></Label></asp:ListItem> 
    <asp:ListItem id="star4" Value=4 runat="server" ><Label for="star4" title="4 stars" ><i class="active fa fa-star" aria-hidden="true"></i></Label></asp:ListItem> 
    <asp:ListItem id="star5" Value=5 runat="server" ><Label for="star5" title="5 stars" ><i class="active fa fa-star" aria-hidden="true"></i></Label></asp:ListItem> 
  </asp:RadioButtonList> 
</asp:Label>

您实际上不需要或不想要您的自定义标签元素。来自documentation :

When the RadioButton control renders to the browser, it does so in two parts: an input element that represents the radio button, and a separate label element that represents the caption for the radio button. The combination of the two elements is wrapped in a span element.
