c# - 在gridview中设置文本框的值

Question

我的 ASP.Net 申请表上有一个 gridview。change我的要求是在文本框的事件中更改 gridview 行内的 4 个标签的值，该txtCTHOrHSN文本框也在 gridview 内。

我正在使用以下 jQuery 代码来获取此文本框的值和另一个来自 gridview 同一行中的标签的值，但是标签值没有改变。这个你能帮我吗。

<asp:GridView ID="gv" runat="server" AutoGenerateColumns="false" EmptyDataText="No Data found..!" CssClass="table table-striped table-bordered table-hover no-margin-bottom no-border-top" DataKeyNames="Id, tableName">

    <asp:TemplateField HeaderText="" ItemStyle-Width="100px">
      <ItemTemplate>
