我有2个GridView，通过一个复选框，我可以在GridView 1（gvAll）中选择行，并将所选行的多个值传递给另一个GridView 2（gvSelected）。而我又将其用于将所选内容插入到数据库中。 GridViews中的数据是用户数据UserId，Firstname，Surname，ServiceNo。我要插入整个选定记录中的每个值。但是，虽然这部分工作正常，但只有当UserId显示在我不想要的GridView中时才有效。我想隐藏UserId但仍然将值插入数据库。 有解决方法吗？

添加TemplateField并使用<asp:HiddenField/>绑定UserId元素。
答案 1 :(得分：0)
您应该能够将要隐藏的列的宽度设置为0来实现此目的。
答案 2 :(得分：0)
感谢03usr和AVD的贡献。但是，通过CSS解决了它 这是
<style type="text/css">
.hide
{
display:none;
}
</style>
<asp:BoundField DataField = "UserId" HeaderText = "UserId" HtmlEncode = "false" ><ItemStyle CssClass="hide"/><HeaderStyle CssClass="hide" /></asp:BoundField >
