假设Rating是一个整数，您可以使用内联代码

<asp:TemplateField>
    <ItemTemplate>                    
        <asp:ImageButton ID="ImageButton" runat="server" ImageUrl="/eur/Home/OfferLetter/images/delete_icon.gif" CausesValidation="false" Visible='<%# int.Parse(Eval("rating").ToString()) >= 1 ? true : false %>' />                                       
        <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="/eur/Home/OfferLetter/images/delete_icon.gif" CausesValidation="false" Visible='<%# int.Parse(Eval("rating").ToString()) >= 2 ? true : false %>' />
        <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="/eur/Home/OfferLetter/images/delete_icon.gif" CausesValidation="false" Visible='<%# int.Parse(Eval("rating").ToString()) >= 3 ? true : false %>' />
        <asp:ImageButton ID="ImageButton3" runat="server"  ImageUrl="/eur/Home/OfferLetter/images/delete_icon.gif" CausesValidation="false" Visible='<%# int.Parse(Eval("rating").ToString()) >= 4 ? true : false %>' />
        <asp:ImageButton ID="ImageButton4" runat="server" ImageUrl="/eur/Home/OfferLetter/images/delete_icon.gif" CausesValidation="false" Visible='<%# int.Parse(Eval("rating").ToString()) >= 5 ? true : false %>' />
    </ItemTemplate>
</asp:TemplateField>
