C# 我需要编辑和更新中继器值
我有一个repeater，它有五列（ITEM、ITEM DESCRIPTION、PRICE、QUANTITY和TOTAL）。我正在从数据库表中将ITEM、ITEM DESCRIPTION和QUANTITY列的值绑定到repeater，两列（PRICE和TOTAL）被认为是空白的，因为这必须由用户填写。我如何实现这一点（它可能有许多行） 这是我的中继器代码：C# 我需要编辑和更新中继器值,c#,asp.net,.net,repeater,C#,Asp.net,.net,Repeater,我有一个repeater，它有五列（ITEM、ITEM DESCRIPTION、PRICE、QUANTITY和TOTAL）。我正在从数据库表中将ITEM、ITEM DESCRIPTION和QUANTITY列的值绑定到repeater，两列（PRICE和TOTAL）被认为是空白的，因为这必须由用户填写。我如何实现这一点（它可能有许多行） 这是我的中继器代码： <div id="RPT"> <table cel

请帮助它完成IMMM…在您的代码示例中，price和total都是标签，我想至少在它们上，它们将在以后更改为文本框，并且您希望在服务器端检索值并进行计算
推回后，通过中继器的项目循环。请注意，不仅会枚举内容项，还会枚举页眉和页脚项，因此您可能需要检查项的类型。对于有问题的项，可以使用FindControl和控件id访问项中的特定控件。通过这种方式，您可以检索或更改项目中的值。以后在将数据存储到数据库中时也可以应用此技术。
在web上有很多这样的例子（，），所以我不提供代码示例
