i changed to Razor as bellow but it can’t work:

@{ 
    private object FormattedValue 
    {        
        get 
        {            
            if (ViewData.TemplateInfo.FormattedModelValue == ViewData.ModelMetadata.Model) 
            {                
                return String.Format(System.Globalization.CultureInfo.CurrentCulture,"{0:0.00}",ViewData.ModelMetadata.Model);
            }            
            return ViewData.TemplateInfo.FormattedModelValue;        
        }    
    }
}

@Html.Encode(FormattedValue)

Create your own function:
http://weblogs.asp.net/hajan/archive/2011/02/05/functions-inside-page-using-razor-view-engine-asp-net-mvc.aspx

just call the function passing it the value in, and return it however you want to format it.

@functions{
    public MvcString FormatValue(object valuetoFormat)
    {
        ...logic here ...
        return ....
    }
}

Calling it is roughly:

@Html.TextBox("", FormatValue(ModelValue), new { @class = "text-box single-line" })
