未触发必填字段验证。

型号:

public class Client
{
[Required(ErrorMessage="Name Required")]
[DisplayFormat(ConvertEmptyStringToNull = false)]
public string Name { get; set; }
public string Address { get; set; }
public string Mobile { get; set; }
public string Telephone { get; set; }
public string Fax { get; set; }
public string Company { get; set; }
}

Controller :

 [HttpPost]
public ActionResult Create(Client client)
{
try
{
// TODO: Add insert logic here
ClientRepository rep = new ClientRepository();
rep.AddClient(client);
rep.Save();
return RedirectToAction("Index");
}
catch
{
return View();
}
}

查看:

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Create
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<h2>Add New Client</h2>

<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>

<fieldset>
<legend>Fields</legend>

<div class="editor-label">
<%: Html.LabelFor(model => model.Name) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Name) %>
<%: Html.ValidationMessageFor(model => model.Name) %>
</div>

<div class="editor-label">
<%: Html.LabelFor(model => model.Address) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Address) %>
<%: Html.ValidationMessageFor(model => model.Address) %>
</div>

<div class="editor-label">
<%: Html.LabelFor(model => model.Mobile) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Mobile) %>
<%: Html.ValidationMessageFor(model => model.Mobile) %>
</div>

<div class="editor-label">
<%: Html.LabelFor(model => model.Telephone) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Telephone) %>
<%: Html.ValidationMessageFor(model => model.Telephone) %>
</div>

<div class="editor-label">
<%: Html.LabelFor(model => model.Fax) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Fax) %>
<%: Html.ValidationMessageFor(model => model.Fax) %>
</div>

<div class="editor-label">
<%: Html.LabelFor(model => model.Company) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Company) %>
<%: Html.ValidationMessageFor(model => model.Company) %>
</div>

<p>
<input type="submit" value="Create" />
</p>
</fieldset>

<% } %>

<div>
<%: Html.ActionLink("Back to List", "Index") %>
</div>

</asp:Content>

最佳答案

使用ModelState.IsValid属性(property)

public ActionResult Create(Client client)
{

if(ModelState.IsValid)
{
// TODO: Add code here
ClientRepository rep = new ClientRepository();
rep.AddClient(client);
rep.Save();
return RedirectToAction("Index");
}
return View(client);
}
