C#-如何对Page_Load中的提交做出反应？

我有很多单选按钮：

<asp:RadioButtonList ID="selectedYesNoQuestionBlock1" runat="server" RepeatDirection="Horizontal"
                OnSelectedIndexChanged="Question1GotAnswered" AutoPostBack="true">
                <asp:ListItem Text="Yes" Value="1"></asp:ListItem>
                <asp:ListItem Text="No" Value="0"></asp:ListItem>
            </asp:RadioButtonList>

<asp:RadioButtonList ID="selectedYesNoQuestionBlock2" runat="server" RepeatDirection="Horizontal"
                AutoPostBack="true" OnSelectedIndexChanged="Question2GotAnswered">
                <asp:ListItem Text="Yes" Value="1"></asp:ListItem>
                <asp:ListItem Text="No" Value="0"></asp:ListItem>
            </asp:RadioButtonList>

等等

对于每个单选按钮,我有他们的方法：

protected void Question1GotAnswered(object sender, EventArgs e)
        {}

我想在方法Question1GotAnswered()被调用之前在Page_Load中对此做出反应.我正在尝试,但是一切都不成功.

尝试过这样的事情：

    protected void Page_Load(object sender, EventArgs e)
        {
 if (sender.ToString() == "Question1GotAnswered")
                    {}
}

请帮助我非常需要它！

解决方法:

唯一的方法是检查if(Request.Form [“ __ EVENTTARGET”] == control.ClientID){},以查看回发的控件是引起回发的给定控件.因此,这应该是引起回发的单选按钮的ID.

HTH.
