我有一个显示评论的gridview。我希望如果有人喜欢评论，请按点赞按钮并增加喜欢的总和，但我不想连接到数据库并绑定。我想使用 ajax 来做到这一点。我怎样才能做到这一点？这是我的代码：
<asp:UpdatePanel runat="server" id="UpdatePanel" >
<ContentTemplate>
<asp:GridView ID="grdCommentsForLoginnedUser"
runat="server"
AutoGenerateColumns="False"
Width="100%"
OnRowCommand="grdCommentsForLoginnedUser_RowCommand"
ViewStateMode="Inherit">
<Columns>
<asp:TemplateField >
<ItemTemplate>
<asp:HiddenField ID="hdnCommentID" runat="server"
Value='<%# Bind("CommentID") %>'/>
<table border="2" dir="rtl">
<tr>
<td rowspan="2" style="background-color: #6699FF" width="200px">
<asp:HyperLink ID="lnkCommenterName"
runat="server"
NavigateUrl='<%# Bind("CommenterProfile") %>'
Text='<%# Bind("CommenterName") %>' />
</td>
<td width="700px">
<br />
<asp:Label ID="lblCommentText" runat="server"
Text='<%# Bind("CommentText") %>' />
<br />
</td>
</tr>
<tr>
<td width="700px">
<asp:Label ID="lblPreviousAcceptOrNonAccept" runat="server"
Text='<%# Bind("PersonPreviousAcceptOrNonAccept") %>' />
<asp:LinkButton ID="lnkBtnRemovePreviousAcceptOrNonAccept"
runat="server"
Text='<%# Bind("RemovePersonPreviousAcceptOrNonAccept") %>'
CommandName="RemovePreviousAcceptOrNonAccept"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />
<br />
<asp:LinkButton ID="lnkBtnUpRate" runat="server" Text="Like"
Visible='<%# Bind("isLikeAndUnlikeButtonVisible") %>'
CommandName="LikeComment"
CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />
<br />sum of likes
<asp:Label ID="lblCommentLikes" runat="server"
Text='<%# Bind("CommentLikes") %>' />
</td>
</tr>
</table>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
