我目前有一个在表格中显示语言信息的视图页面和一个编辑链接，该链接将带我进入新的视图页面以编辑语言信息。我试图让所有内容都保留在一页上，这样用户就不会感到困惑。我尝试过使用 Html.RenderPartial 它将呈现视图，但不会带来信息。我已经没有任何想法可以让这项工作成功，任何帮助都将不胜感激。

您需要将 OfficeLangVM 模型传递到 LanguageUpdate 视图，如下所示：
<tr style="display:none" >
@{
Html.RenderPartial("~/Views/Agency/LanguageUpdate.cshtml",Model);
}
</tr>
