自定义的ValidationSummary模板Asp.net MVC 3

问题描述

我的工作与Asp.Net MVC3

项目

在一个视图我有 @ Html.ValidationSummary（真）和它通常会产生

 ＆LT; D​​IV CLASS =验证，汇总错误＆GT;
    ＆LT; UL＆GT;
        ＆LT;立GT;中发生了一点＆LT;！/李＆GT;
    ＆LT; / UL＆GT;
＆LT; / DIV＆GT;
 

如何延长这个的ValidationSummary到MyValidationSummary和产生的HTML code ++模板是这样的：

 ＆LT; D​​IV CLASS =通知警告＆GT;
    ＆LT;跨度＆GT;＆LT; / SPAN＆GT;
    ＆LT; D​​IV CLASS =文本＆GT; ＆LT; P＆GT;中发生了一点＆LT;！/ P＆GT; ＆LT; / DIV＆GT;
＆LT; / DIV＆GT;
 

解决方案

这question详细编写自定义验证总结的过程。

修改
这将做你想要什么：

 公共静态类LinqExt
    {
        静态字符串MyValidationSummary（此的HtmlHelper帮手，串validationMessage =）
        {
            字符串retVal的=;
            如果（helper.ViewData.ModelState.IsValid）
                返回;
            retVal的+ =＆LT; D​​IV CLASS ='通知的警告'＆GT;＆LT;跨度＆gt;中;
            如果（！String.IsNullOrEmpty（validationMessage））
                retVal的+ = helper.En code（validationMessage）;
            retVal的+ =＆LT; / SPAN＆gt;中;
            retVal的+ =＆LT; D​​IV CLASS ='文本'＆gt;中;
            的foreach（在helper.ViewData.ModelState.Keys VAR键）
            {
                的foreach（在helper.ViewData.ModelState VAR错误[关键] .Errors）
                retVal的+ =＆所述; P＆gt;中+ helper.En code（err.ErrorMessage）+＆LT; / P＆gt;中;
            }
            retVal的+ =＆LT; / DIV＆GT;＆LT; / DIV＆gt;中;
            返回retVal.ToString（）;
        }
    }
 

在code是自我解释;刚刚经历的ModelState错误列举，并在您选择的DOM元素包装的错误。还有就是如果我使用它像一个错误：

 ＆LT;％：Html.MyValidationSummary（）％GT;
 

这将在页面文本上显示HTML标签，而不是渲染它。

 ＆LT;％= Html.MyValidationSummary（）％GT;
 

这工作得很好。

I am working on a project with Asp.Net MVC3

In a View I have @Html.ValidationSummary(true) and as usually it produces

<div class="validation-summary-errors">
    <ul>
        <li>Something bad Happened!</li>
    </ul>
</div>

How can I extend this ValidationSummary to MyValidationSummary and produces the Html Code template something like this:

<div class="notification warning">
    <span></span>
    <div class="text"> <p>Something bad Happened!</p> </div>
</div>

解决方案

This question details the procedure of writing custom validation summary.

EDITThis will do what you want:

 public static class LinqExt
    {
        static string MyValidationSummary(this HtmlHelper helper, string validationMessage="")
        {
            string retVal = "";
            if (helper.ViewData.ModelState.IsValid)
                return "";
            retVal += "<div class='notification-warnings'><span>";
            if (!String.IsNullOrEmpty(validationMessage))
                retVal += helper.Encode(validationMessage);
            retVal += "</span>";
            retVal += "<div class='text'>";
            foreach (var key in helper.ViewData.ModelState.Keys)
            {
                foreach(var err in helper.ViewData.ModelState[key].Errors)
                retVal += "<p>" + helper.Encode(err.ErrorMessage) + "</p>";
            }
            retVal += "</div></div>";
            return retVal.ToString();
        }
    }

The code is self explanatory; just enumerating through modelstate errors and wrapping errors in dom element of your choice. There is an error that is if i use it like:

<%:Html.MyValidationSummary()%>

It will display html tags on the page as text rather than rendering it.

<%=Html.MyValidationSummary()%>

This works fine.
