[英]How to extend the ValidationSummary HTML Helper in ASP.NET MVC?
I need to wrap the Validation Summary in a div . 我需要将验证摘要包装在div中 。 How do I set the Validation Summary to wrap it with a div when errors are present?
当出现错误时,如何设置验证摘要以将其包装为div ?
<div class="validation-summary">
<%= Html.ValidationSummary("Login was unsuccessful. Please correct the errors and try again.") %>
</div>
I had to extend the validation summary extensions in another project of mine to deal with more than one form on a page. 我不得不在我的另一个项目中扩展验证摘要扩展,以处理页面上的多个表单。
Although this is different, you could create your own extension method... 虽然这有所不同,但您可以创建自己的扩展方法......
namespace System.Web.Mvc
{
public static class ViewExtensions
{
public static string MyValidationSummary(this HtmlHelper html, string validationMessage)
{
if (!html.ViewData.ModelState.IsValid)
{
return "<div class=\"validation-summary\">" + html.ValidationSummary(validationMessage) + "</div>"
}
return "";
}
}
}
Then just call 然后打电话
<%= Html.MyValidationSummary(
"Login was unsuccessful. Please correct the errors and try again.") %>

What you can do is this : 你能做的是:
<%if (!ViewData.ModelState.IsValid) { %>
<div class="validation-summary">
<%= Html.ValidationSummary(
"Login was unsuccessful. Please correct the errors and try again.") %>
</div>
<% } %>
对于MVC 2,ValidationSummary是一种扩展方法,您必须添加
using System.Web.Mvc.Html;
例如,将此CSS用于li标签...
.validation-summary-errors ul li {color:Red;}
