How to pass a parameter to HyperLink in GridView/DataList
The elegant code is just as follows.
<asp:HyperLink runat="server" NavigateUrl='<%# Eval("ID", "~/theurl.aspx?id={0}") %>' Text='<%# Eval("Title") %>'/>
or you could do the concatination like this:
property='<%# 'foo' + Eval("value")%>'
But DONOT do this:
property='foo<%#Eval("value")'
