C# SelectedIndexChanged在RadioButton时不工作列出所选asp.net c？自动回邮也设置为true？

我在这里挣扎了很久。。。请帮忙。。 下面是aspx页面代码

<asp:RadioButtonList ID="sing_group" runat="server" RepeatDirection="Horizontal" 
                        onselectedindexchanged="sing_group_SelectedIndexChanged" AutoPostBack="true">
                        <asp:ListItem Value="0">Single</asp:ListItem>
                        <asp:ListItem Value="1">Group</asp:ListItem>
                    </asp:RadioButtonList>

根据，事件名称为OnSelectedIndexChanged 在您的代码中，所有这些都是小规模的

<asp:RadioButtonList id="RadioButtonList1" 
            OnSelectedIndexChanged="Index_Changed"
            AutoPostBack="true"
            runat="server"/>

也试着这样做。。这是肯定的

<asp:RadioButtonList ID="sing_group" runat="server" RepeatDirection="Horizontal" 
                       AutoPostBack="true">
                        <asp:ListItem Value="0">Single</asp:ListItem>
                        <asp:ListItem Value="1">Group</asp:ListItem>
                    </asp:RadioButtonList>

Protected Void Page_Load(Object Sender, EventArgs e){
    sing_group.SelectedIndexChanged += sing_group_SelectedIndexChanged;
}
protected void sing_group_SelectedIndexChanged(object sender, EventArgs e)
{

    if (sing_group.SelectedValue == "0")
    {
        first_name.Enabled = true;
        last_name.Enabled = true;
        group_name.Enabled = false;
    }
    else
    {
        first_name.Enabled = false;
        last_name.Enabled = false;
        group_name.Enabled = true;
    }

}

你写错代码了。请更改您的密码

您的代码是：

onselectedindexchanged="sing_group_SelectedIndexChanged"

但应该是：

OnSelectedIndexChanged="sing_group_SelectedIndexChanged"

您可以获得输出。

当您在调试中进入sing\u group\u SelectedIndexChanged on change index时，什么不起作用？代码看起来不错。使用调试器在加载sing\u group\u SelectedIndexChanged页面设置断点

OnSelectedIndexChanged="sing_group_SelectedIndexChanged"
