前台代码
  <asp:Repeater ID="Repeater1" runat="server">
                        <ItemTemplate>
                            <table width="90%">
                                <tr style="width: 22.5%">
                                    <td>
                                        <%#Eval ("title") %>
                                    </td>
                                   
                                    <td>
                                        <asp:HiddenField ID="HideID" Value='<%#Eval("ID") %>' runat="server" />
                                    </td>
                                </tr>
                                <tr style="width: 22.5%">
                                    <td>
                                        <%#Eval ("adddata") %>
                                    </td>
                                </tr>
                                <tr style="width: 22.5%">
                                    <td>
                                        <%#Eval ("note")%>

Answer 4

你可以把评论换成一个LinkButton，如：
<asp:LinkButton ID="LinkButton1" runat="server" PostBackUrl='<%# "~/Comment.aspx?id="+Eval("id") %>'评论></LinkButton>然后，但页面跳转到评论的页面后：你就可以通过Request["id"]得到日志的id了

Answer 5

前台的Button中加上ID参数：
<asp:Button ID="BtnSave" runat="server" Text="发表" OnClick="BtnSave_Click"
 CommandArgument='<%# Eval("id") %>' />后台可以从事件的sender中读到这个ID，如：
protected void BtnSave_Click(object sender, EventArgs e)
{
  string id = (sender as Button).CommandArgument;
  ...
}
