新闻的内容页问题（人人都有分）
新闻列表页我用GirdView 控件显示新闻列表：NewsList.aspx
ID传值到ShowNews.apx页面
在
ShowNews.apx 我用什么方法（或者控件）显示新闻的标题、发布时间、新闻内容呢
有代码实例说明最佳
[解决办法]
页面后台代码
public DataEntity.Article article;
public int ArticleID
{
get
{
if (ViewState["ArticleID"] != null && TypeParse.IsNumeric(ViewState["ArticleID"]))
return Convert.ToInt32(ViewState["ArticleID"]);
else
return 0;
}
set
{
ViewState["ArticleID"] = value;
}
}
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
if (Request.QueryString["ArticleID"] != null && TypeParse.IsNumeric(Request.QueryString["ArticleID"]))
{
ArticleID = Convert.ToInt32(Request.QueryString["ArticleID"]);
}
}
BindData();
}
private void BindData()
{
ArticleManager am = new ArticleManager();
article = am.GetModel(ArticleID);
}
aspx页面
<table class="artictable">
<tr>
<th class="blanklink">
<%=article.Title%>
</th>
<td class="datetd">
<%=article.CreateDate.Value.ToString("yyyy-MM-dd")%>
</td>
</tr>
<tr>
<td colspan="2">
<%=article.Content%>
</td>
</tr>
</table>
[解决办法]
private void Page_Load(object sender, System.EventArgs e) { // 在此处放置用户代码以初始化页面 if (!IsPostBack) { string strId = Request.QueryString["id"].ToString(); string strSql = "select * from TS_SERVER_MGR where SM_id='" +strId+ "'"; BaseService bc = new BaseService(); DataTable dt = bc.ExecuteDataTable(strSql); foreach (DataRow dr in dt.Rows) { lbl3.Text = dr["标题"].ToString(); lbl2.Text = dr["时间"].ToString(); lbl1.Text = dr["内容"].ToString(); } } }
[解决办法]
用表达式显示就可以了啊
<table
<tr>
<td>
<%=article.Title%>
<td>
</tr>
<tr>
<td>
<%=article.Content%>
</td>
</tr>
</table>
[解决办法]
后台
public partial class ArticleShow : System.Web.UI.Page{ public string ArticleTitle = ""; public string ArticleContent = ""; protected void Page_Load(object sender, EventArgs e) { //if (!Page.IsPostBack) //{ if ((Request.Params["id"] != null) && (Request.Params["id"].ToString() != "")) { string id = Request.Params["id"]; ShowArticle(int.Parse(id)); } //} } private void ShowArticle(int ArticleID)//显示新闻 { model = bll.GetModel(ArticleID); ArticleTitle = model.ArticleTitle; ArticleContent = model.ArticleContent; }}
[解决办法]
lz在送分？
用formview（专为绑定一条数据的）
前台：
<asp:FormView ID="FormView1" runat="server" Width="100%">
<ItemTemplate>
<table align="center" bgcolor="#ffffff" border="1" bordercolordark="#efefef" bordercolorlight="#83bbd9"
cellspacing="0" class="bian" width="95%">
<tr>
<td bgcolor="#ffffff" class="contact1" height="26" width="26%">
新闻标题 <%#Eval("news_title")%></td>
<td bgcolor="#ffffff" class="contact1" width="24%">
新闻内容：<%#Eval("news_content")%></td>
<td bgcolor="#ffffff" class="contact1" style="width: 284px">
作者:<%#Eval("news_author")%></td><td class="contact1">
时间<%#Eval("news_time")%></td>
</tr>
</table>
</ItemTemplate>
后台：
直接绑定（就不用写了吧）1楼很详细
楼主要加强学习了
