c# - ASP.NET MVC 客户端验证消息错误

Question

有人能告诉我为什么显示“此字段为必填项”和“请插入数据库名称”而不是仅显示“请插入数据库名称”吗？

这是我的模型:

public class InstallViewModel
    {
        [Required(AllowEmptyStrings = false, ErrorMessage = "Please insert database name")]
        public string DatabaseName { get; set; }

这是我的观点:

<div class="input-group">
    <span class="input-group-addon">Database</span>
    @Html.TextBoxFor(w => w.DatabaseName, new { @class = "form-control", placeholder = "Database name" })
</div>
@Html.ValidationMessageFor(w=> w.DatabaseName)

谢谢。

编辑:

你能看到附件中的图片吗？我在上传图片时遇到了一些问题。

View 是局部 View ，这是整个局部 View :

@Html.ValidationMessageFor(w => w.DatabaseName)
    <div class="input-group">
        <span class="input-group-addon">Database</span>
        @Html.TextBoxFor(w => w.DatabaseName, new { @class = "form-control", placeholder = "Database name" })
    </div> 
    <br />
    @Html.CheckBoxFor(w => w.UseWindowsAuthentication, new { @checked = "checked" }) Use Windows Authentication<br /><br />
    <div class="wizard-sqlauth" style="display: none">
        <div class="input-group">
            <span class="input-group-addon">User name</span>
            @Html.TextBoxFor(w => w.UserName, new { @class = "form-control", placeholder = "User name" })
        </div>
        @Html.ValidationMessageFor(w => w.UserName)<br />
        <div class="input-group">
            <span class="input-group-addon">Password</span>
            @Html.PasswordFor(w => w.Password, new { @class = "form-control" })
        </div>
        @Html.ValidationMessageFor(w => w.Password)
    </div>

Answer 1

DatabaseName 为“必填”，您的输入为空。 (只有占位符文本)
