datalist綁定

Question

我做论坛的帖子加入精华时    读取帖子标题 如果该帖子是精华帖就在标题后面加上一个图片 怎么实现啊？  ItemDataBound中绑定不行啊 这样每个帖子都加上了digest_1.gif这张图片代码如下
 
 protected void BindTieZi_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            string isPrettys = ViewState["isPretty"].ToString();
            Image img = (Image)e.Item.FindControl("SJH");  //  y表示是精华帖
            if (isPrettys == "Y")
            {
                img.ImageUrl = "~/images/digest_1.gif";            }
            else
            {
                img.ImageUrl = "images/qj.gif";
            }        }
    }

用样式来控制代码片段                StringBuilder sb = new StringBuilder();
                foreach (ForumTopics ent in listTopic) {
                    sb.Append(@"<ul class='BBSTopicUlText'>");                    sb.Append("<li style='width: 2%; margin-left: 4px !important; margin-left: 2px;'><div class='BBSTopicTextAuthor'>");
                    if (bIsMaster) {
                        sb.Append("<input type='checkbox' id='cbxTid' name='cbxTid' value='" + ent.Tid + "' />");
                    }
                    sb.Append("</div></li>");                    sb.Append(@"<li style='width: 57%;'>");
                    sb.Append(@"<div class='BBSTopicTextImg' style='float: left'>");
                    GlobalVariable.ForumTopicStateEnum topicState = GlobalVariable.GetTopicState(ent);
                    string strImg = GlobalVariable.GetTopicImgPath(topicState);
                    if (topicState == (GlobalVariable.ForumTopicStateEnum.Top | GlobalVariable.ForumTopicStateEnum.Digest)) {
                        //置顶、精华状态同时存在时先取置顶
                        strImg = GlobalVariable.GetTopicImgPath(GlobalVariable.ForumTopicStateEnum.Top);
                    }
                    string strImgAlt = GlobalVariable.GetTopicStateImgAlt(topicState);
                    //sb.Append("<span style='width:20px;'>");

                                break;
                            }
                        }
                    }
                    sb.Append("</div>");
                    sb.Append(@"<div class='BBSTopicTextImg' style='float: right'>");                    //sb.Append(@"<img src='/Main_Style/WoHoopsV2/icon/Forum/N012.png' />");

Answer 2

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataRow row = ((DataRowView)e.Item.DateItem).Row;
            string isPrettys = row["SJH"].ToString();//  y表示是精华帖
            if (isPrettys == "Y")
            {
                img.ImageUrl = "~/images/digest_1.gif";            }
            else
            {
                img.ImageUrl = "images/qj.gif";
            }        }

Answer 3

在模板列
<%# ((bool)Eval("SJH"))?"<img src=\"images/digest_1.gif\"/>":""%>
