如何从控制器传递信息到视图然后用asp.net mvc将其恢复到控制器？

I'm pretty sure it's easy but I can't seem to find it.

我很确定这很容易,但我似乎无法找到它。

I have 2 table linked together in sql;

我在sql中有2个表链接在一起;

   table1 with field named idTable1, info
   table2 with field named idTable1, idTable2, moreInfo

when I show the view that can add a new row into table2, I have access to idTable1

当我显示可以向table2添加新行的视图时,我可以访问idTable1

 <%=Html.Encode(Model.idTable1)%>

but when I submit for form, I'm losing that information, in the controller the IdTable1 is now empty

但是当我提交表单时,我正在丢失该信息,在控制器中IdTable1现在是空的

how to fix that "problem" ?

如何解决这个“问题”?

thanks!

Instead of using Html.Encode, you might try using Html.Hidden. Example:

您可以尝试使用Html.Hidden,而不是使用Html.Encode。例:

<form>
...
<%= Html.Hidden("idTable1", Model.idTable1) %>
...
</form>

This will submit the value for idTable1 along with the form data.

这将提交idTable1的值以及表单数据。
