我有以下快照代码:
我的ViewClass看起来像这样:
...
<%=Html.ValidationSummary() %>
...
<div class="editor-field-short">
<%: Html.TextBox("Identity", Model.Identity, new Dictionary<string, object>
{
{ "class", "textbox DependantIdPassportTextBox" },
{ "data-val", "true" },
{ "data-val-required", "Please enter the Identity Number" },
},)%>
<div class="editor-container"><%=Html.ValidationMessageFor(m => m.Identity)%></div>
</div>
控制器类
public ActionResult ValidateMember(String Identity)
{
...
var memberIdNo = MemberProfileService.GetProfileByIdNumber(Identity);
if (memberIdNo == null)
{
ModelState.AddModelError("Identity", "Member does not exist");
return View("Index");
}
...
因此,如果MemberIdNo == Null为true,则错误消息“Member is not exists”不会显示在我的ViewClass中。
更新
所以我得到以下内容: 你调用的对象是空的。 在这一行:&lt;%:Html.TextBox(“Identity”,Model.Identity,new Dictionary
答案 0 :(得分:0)
我明白了。
我用过:&lt;%:Html.TextBox For (...)并删除了这一行:
<div class="editor-container"><%=Html.ValidationMessageFor(m => m.Identity)%></div>
打印每条验证消息:&lt;%= Html.ValidationSummary()%&gt;
