我目前正在页面加载时动态填充文本框。然后我使用 OnClick 命令从所述文本框中提取信息
我的 ASPX 表
<div class="mi_Container" id="Edit">
<div class="mi_Title">
<asp:Label ID="App_Name_E" runat="server" />
</div>
<hr />
<table class="mi_Inner_Container">
<tr>
<td class="mi_Desc">
Description: <br />
<asp:TextBox ID="Description_E" Rows="6" CssClass="mi_Textarea" TextMode="MultiLine" runat="server" />

<td class="mi_Center">

</tr>
<tr>
<td class="mi_Rows">

因此,当我运行 OnClick 时,它确实正确运行了 SQL 命令,因为最后一个更新字段正确复制并更新了 SQL 行。我的问题是所有其他变量都没有设置为新值。
我最近一直在为这个项目发布问题,这恰好是我第一次使用 ASP
我假设它与页面如何处理变量有关。我只是更改值并没有再次设置它们。
任何和所有的帮助表示赞赏。
