ASP.NET MVC 保存按钮加载但不工作

Question

我在我的 .NET 应用程序的索引页面上实现了一个保存按钮。当我单击它时，它会加载，但不会保存任何内容。我只是将索引页用于复选框。如果我取消选中并保存它，它会保存，但也会取消选中该行中的所有其他内容。当我尝试检查某些内容时，什么也没有发生。这是我正在使用的代码：

索引.cshtml

@using (Html.BeginForm("save", "drnos"))
{
    <input type="submit" value="Save" />
}

我的复选框字段之一的示例：

<td>
    @Html.EditorFor(modelItem => item.Soft)
    @Html.ValidationMessageFor(modelItem => item.Soft)
</td>

drnosController.cs

[HttpPost]
public ActionResult save(Doctor doc)
{
    System.Diagnostics.Debug.WriteLine("Save Called");
    db.Entry(doc).State = EntityState.Modified;
    db.SaveChanges();
    return RedirectToAction("Index");  
}

这是整个 HTML 文件：

@model PagedList.IPagedList<drnosv6.Models.Doctor>
@using PagedList.Mvc;

<link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />


@{
    ViewBag.Title = "Index";
}

<h2>Doctors</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
@using (Html.BeginForm()) //insert the search bar
{
    <p>
        Find by First Name, Last Name, or RVH ID: @Html.TextBox("SearchString")

        <input type="submit" value="Search" />

    </p>
}

@using (Html.BeginForm("save", "drnos"))
{
    <input type="submit" value="Save" />
}

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $('tr:even').addClass('alt-row-class');
    });

</script>

<p>    
</p>

<p>Click on a column header to sort by that column</p>

    <tr>
        <th>
            @Html.ActionLink("RVH ID", "Index", new { sortOrder = ViewBag.IDSortParm })

Answer 1

提交表单时，只有在该表单中声明的​​输入才会被提交。您的表单中只有提交按钮，因此没有其他字段可以填写您的 Doctor 结构。您需要将保存按钮放在与所有其他字段相同的表单上。

Answer 2

您的 BeginForm 或 ActionLink 必须指向 ActionResult Edit。
