添加自定义属性表进行的WebGrid呈现 [英] Add custom attributes to table rendered by WebGrid

问题描述

我正在使用MVC3的WebGrid，并希望添加表格数据-XXX的自定义属性的＆LT;表＆gt; 元素通过<$ C $呈现C> WebGrid.GetHtml（）。

I am using an MVC3 WebGrid, and want to add custom attributes of the form "data-xxx" to the <table> element rendered by WebGrid.GetHtml().

我试图做到这一点，如下所示：

I tried to do this as follows:

grid.GetHtml(...
    htmlAttributes: new { data_xxx = "value" }
);

然而，这呈现为：

However this renders as:

<table ... data_xxx="value">

代替

预期的：

instead of the expected:

<table ... data-xxx="value">

即。不像其他的MVC助手，它没有连字符替换属性名下划线。

I.e. unlike other MVC helpers, it doesn't replace the underscore in the property name with a hyphen.

在进行位，且反射洞穴探险的好像是：

After a bit of spelunking with Reflector it seems that:

1. WebGrid.GetHtml（）电话 System.Web.WebPages.Html.ObjectToDictionary 来转换匿名属性对象字典。不同于方法 System.Web.Mvc.HtmlHelper.AnonymousObjectToHtmlAttributes 使用其他帮助，这并不能代替_为 - 。

1. WebGrid.GetHtml() calls System.Web.WebPages.Html.ObjectToDictionary to convert the anonymous attributes object to a dictionary. Unlike the method System.Web.Mvc.HtmlHelper.AnonymousObjectToHtmlAttributes used by other helpers, this doesn't replace "_" by "-".

与大多数其他MVC佣工， WebGrid.GetHtml（）不具有过载，它接受一个的IDictionary＆LT;字符串，对象＆gt; ，所以无法通过指定属性以这种方式解决该问题。

Unlike most other MVC helpers, WebGrid.GetHtml() does not have an overload that takes an IDictionary<string, object>, so I can't work around the bug by specifying the attributes in this way.

这看起来像我的错误，我已经提交给连接：

This looks like a bug to me, and I've submitted it to Connect:

有一种变通方法有什么建议？抑或是固定MVC4？

Any suggestions for a workaround? Or is it fixed in MVC4?
