推荐答案

你可以这样做在aspx文件中。

You can do that in aspx file.

<asp:GridView ID="searchProductGridView" runat="server" AutoGenerateColumns="false" DataKeyNames="ProductCode"

                        CssClass="gridview" AlternatingRowStyle-CssClass="alternatingRow" AllowPaging="true" PagerStyle-CssClass="paging" OnPageIndexChanging="searchProductGridView_PageIndexChanging">
                        <Columns>
                            <asp:TemplateField HeaderText="Select">
                                <ItemTemplate>
                                    <asp:CheckBox ID="selectChkBox" runat="server" ToolTip="Add to Cart" />
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="Code" ControlStyle-Width="150px">
                                <ItemTemplate>
                                    <asp:LinkButton ID="codeLink" runat="server" Font-Size="9" ForeColor="#1C329F" CssClass="link" Font-Underline="false"

                                        Text='<%#Eval("ProductCode") %>' OnClick="codeLink_Click" />
                                </ItemTemplate>
                            </asp:TemplateField>
