在Repeater中添加runat="server"的div，并控制

aspx页代码：

<asp:Repeater ID="rptBlog" runat="server" DataSourceID="objBlog" OnItemDataBound="rptBlog_ItemDataBind">
    <ItemTemplate>
        <div id="rptBlogTitle">
            <h3>
                <a>
                    <%#eval_r( "blogTitle") %>
                </a>
            </h3>
            (
            <%#eval_r( "blogDate") %>
                )
        </div>
        <div id="divBlogEditDel" runat="server" visible="false">
            <a href="EditBlog.aspx">
                [编辑]
            </a>
            <a href="#">
                [删除]
            </a>
        </div>
        <div id="rptBlogTypeName">
        </div>
        <div id="rptBlogContent">
            <%#eval_r( "blogContent") %>
        </div>
        <div id="rptBlogFooter">
            <a href="blogContent.aspx">
                查看全文
            </a>
        </div>
    </ItemTemplate>
</asp:Repeater>

后台代码：

protected void rptBlog_ItemDataBind(object sender, RepeaterItemEventArgs e)
        {
            if (Session["UserName"] != null)
            {

                if (Session["UserName"].ToString() == this.bc_UserName.GetBlog_UserName())
                {
                    e.Item.FindControl("divBlogEditDel").Visible = true;
                }
            }
        }
