从以下位置更改代码:

Hi,

Try this if could help...
Change your code from:

<asp:TemplateField HeaderText="Image">
   <ItemTemplate>
      <asp:Image ID="Image1" runat="server" ImageUrl='<%# "HandlerCategory1.ashx?ID=" & Eval("ID")%>' />
   </ItemTemplate>
<asp:TemplateField>

例如:

to example:

<asp:TemplateField HeaderText="Image">
   <ItemTemplate>
      <a href='PhotoDetail.aspx?id= <%# Eval("ID") %>'>
         <img src='<%# "HandlerCategory1.ashx?ID=" + Eval("ID") %>' alt='<%# Eval("Picture") %>' />
      </a>
   </ItemTemplate>
  <ItemStyle HorizontalAlign="Justify" VerticalAlign="Middle"></ItemStyle>
</asp:TemplateField>

问候
