问题描述

我已经安装了ASP.NET MVC3。我需要datepicker与格式化的日期。我尝试了这个,但它不工作(当通过{0:dd / MM / yyyy}作为格式参数,它仍然不格式):

pre (this HtmlHelper< TModel> htmlHelper,Expression< Func< TModel,TProperty>>表达式,字符串格式,RouteValueDictionary htmlAttributes)
{
var metadata = ModelMetadata.FromLambdaExpression(expression,htmlHelper.ViewData);

if(metadata.Model!= null& metadata.Model as DateTime?!= null)
htmlAttributes.Add(value,string.Format(format,(DateTime )metadata.Model));

return htmlHelper.TextBoxFor(expression,htmlAttributes);



$ b编辑:如果格式为{0:dd-MM- yyyy},但不仅仅是{0:dd / MM / yyyy}

我知道MVC4已经有了这个功能,但不幸的是我的项目是写在MVC3 。你可以帮我吗?

解决方案

我唯一的工作格式是:

  @ Html.TextBoxFor(m => m.Birthdate,{0:MM / dd / yyyy})


I have ASP.NET MVC3 installed. I need datepicker with formatted date. I tried this, but it's not working (when passing "{0:dd/MM/yyyy}" as format parameter, it still does not format):

    private static MvcHtmlString FormattedDateTextBoxFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, string format, RouteValueDictionary htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);

        if (metadata.Model != null && metadata.Model as DateTime? != null)
            htmlAttributes.Add("value", string.Format(format, (DateTime)metadata.Model));

        return htmlHelper.TextBoxFor(expression, htmlAttributes);
    }

EDIT: My code works if format is "{0:dd-MM-yyyy}" but not only for "{0:dd/MM/yyyy}"

I know that MVC4 has already this functionality, but unfortunately my project is written on MVC3. Can you help me?

解决方案

The only format I have even gotten to work is this:

@Html.TextBoxFor(m => m.Birthdate, "{0:MM/dd/yyyy}")
