回发时模型值丢失
我有以下模型:
class A
{
// ...some properties
public B InnerField { get; set; }
}
和
class B
{
public int Id { get; set; }
// ..other properties
}
一个具有模型 A 类的页面,在页面内我有一个绑定到表单内的 B 类的部分视图。 Id 的值(在部分视图中)已正确设置为模型的 Id 值(不同于 0),但当我提交页面时,模型的 Id 值为 0。 Id 值不会在组件或其他地方修改。
页面
...other parts of main page
<%using (Html.BeginForm("ModifyHotel", "Hotel",
FormMethod.Post, new { enctype = "multipart/form-data"}))
{%>
<% Html.RenderPartial("~/Views/Shared/ModifyBaseItem.ascx",
new ModifyItemRequestBaseView() { ItemId = Model.Item.Id });%>
<%}%>
...other parts of main page
部分视图
...other parts of partial view
<br/>
Add Photo: <%:Html.FileBoxFor(x => x.PhotoFile, null)%>
<br/>
Add Video: <%:Html.FileBoxFor(x => x.VideoFile, null)%>
<br/>
<input type="submit" value="Submit changes" />
...other parts of partial view
如何在发帖时保留内部模型的值?
谢谢,
I have the following models:
class A
{
// ...some properties
public B InnerField { get; set; }
}
and
class B
{
public int Id { get; set; }
// ..other properties
}
and a page that has a model Class A and inside the page I have a partial view bound to Class B inside a form.
The value of the Id (in the partial view) is set correctly to the model's Id value (different from 0) but when I submit the page the model has the Id value 0. The Id value is not modified in the component or elsewhere.
Page
...other parts of main page
<%using (Html.BeginForm("ModifyHotel", "Hotel",
FormMethod.Post, new { enctype = "multipart/form-data"}))
{%>
<% Html.RenderPartial("~/Views/Shared/ModifyBaseItem.ascx",
new ModifyItemRequestBaseView() { ItemId = Model.Item.Id });%>
<%}%>
...other parts of main page
Partial View
...other parts of partial view
<br/>
Add Photo: <%:Html.FileBoxFor(x => x.PhotoFile, null)%>
<br/>
Add Video: <%:Html.FileBoxFor(x => x.VideoFile, null)%>
<br/>
<input type="submit" value="Submit changes" />
...other parts of partial view
What can I do to keep the value of the inner model when the post is made?
Thanks,
