推荐答案

单选按钮中缺少 OnSelectedIndexChanged="radiobutton_selectchanged"

You are missing OnSelectedIndexChanged="radiobutton_selectchanged" in the radio button

<asp:radiobuttonlist id="rdbRemarks" runat="server" AutoPostBack="True" repeatdirection="Horizontal" OnSelectedIndexChanged="radiobutton_selectchanged ">
    <asp:listitem value="F1">Accept</asp:listitem>
    <asp:listitem value="F1">Objection Clear</asp:listitem>
    <asp:listitem value="F4">Objection</asp:listitem>
    <asp:listitem value="R">Reject</asp:listitem>
</asp:radiobuttonlist>

后面的代码也必须定义此处理程序

also the code behind must have this handler defined

protected void radiobutton_selectchanged(object sender, EventArgs e)
    {

    }

您的所有代码几乎正确，但是您错过了单选按钮列表中onselectedindexchanged事件，因此在设计页面的单选按钮列表中首先双击事件，以便在后端生成radiobutton_selectchanged代码，然后检查....

Your All Code is almost right but u missing onselectedindexchanged events in radio button list so first double click events in radio button list in your design page so it generate radiobutton_selectchanged in back end code then check ….
