我正在使用数据列表显示存储在SQL Server数据库中的新闻报道摘要。
< asp: DataList ID =DL_NewsSummaryrunat =serverDataKeyField =newsItemId DataSourceID =DS_NewsSummary> < ItemTemplate> < h3> < asp:HyperLink ID =headlineLinkrunat =serverText ='<%#Eval(headline)%>'NavigateUrl =#/> < / h3> < asp:Label ID =dateLabelrunat =serverText ='<%#Eval(date)%>'/> < br /> < asp:Label ID =introLabelrunat =serverText ='<%#Eval(intro)%>'/> < hr /> < / ItemTemplate> < / asp:DataList>当用户点击标题超链接时,他们应该在单独的页面上看到完整的故事, news.aspx 。此页面将从查询字符串中获取 newsItemId ,并使用与该ID相关联的故事填充页面,例如 news.aspx?newsItemId = 1 。
然而,当我将navigateUrl字段更改为以下内容时,我得到一台服务器标签形成错误。
< asp:HyperLink ID =headlineLinkrunat =serverText ='< %#Eval(标题)%>'NavigateUrl =news.aspx?newsItemId =<%#Eval(newsItemId)%> />非常感谢任何帮助
试试这个: NavigateUrl ='<%#news.aspx?newsItemId = + Eval(newsItemId)%>'
I am using a datalist to display a summary of news stories stored in a SQL Server database.
<asp:DataList ID="DL_NewsSummary" runat="server" DataKeyField="newsItemId" DataSourceID="DS_NewsSummary"> <ItemTemplate> <h3> <asp:HyperLink ID="headlineLink" runat="server" Text = '<%# Eval("headline") %>' NavigateUrl="#" /> </h3> <asp:Label ID="dateLabel" runat="server" Text='<%# Eval("date") %>' /> <br /> <asp:Label ID="introLabel" runat="server" Text='<%# Eval("intro") %>' /> <hr /> </ItemTemplate> </asp:DataList>When the user clicks the headline hyperlink they should be taken to the full story on a separate page, news.aspx. This page will get the newsItemId from the querystring and populate the page with the story associated with that id e.g. news.aspx?newsItemId=1.
However when I change the navigateUrl field to the following I get a server tag not well formed error.
<asp:HyperLink ID="headlineLink" runat="server" Text = '<%# Eval("headline") %>' NavigateUrl="news.aspx?newsItemId=<%# Eval("newsItemId") %>" />Any help is greatly appreciated
解决方案Try this:
NavigateUrl='<%# "news.aspx?newsItemId=" + Eval("newsItemId") %>'
