[解决办法]
<asp:HyperLink rnuat= "server " Font-Bold= "True " Text= ' <%# DataBinder.Eval(container.DataItem, "Subject ") %> ' NavigateUrl= ' <%# "Topic.aspx?TopicID= " + DataBinder.Eval(Container.DataItem, "TopicID ") %> ' />
===========================================================
<asp:HyperLink runat= "server " Font-Bold= "True " Text= ' <%# DataBinder.Eval(Container.DataItem, "Subject ") %> ' NavigateUrl= ' <%# "Topic.aspx?TopicID= " + DataBinder.Eval(Container.DataItem, "TopicID ") %> ' />
rnuat --> runat
container --> Container
