TextBoxFor扩展的HtmlHelper

Question

所以我有这个文本框的网页上：

<%= Html.TextBox("EffectiveDate", Model.EffectiveDate.HasValue ? Model.EffectiveDate.Value.ToString("dd-MMM-yyyy") : "", new { @class = "economicTextBox", propertyName = "EffectiveDate", onchange = "parseAndSetDt(this); ", dataType = "Date" })%> 

它存储并显示使用日期选择器的日期。基本上，根据用户的权限，我希望这个文本框被禁用/启用。这很好，我可以做到这一点，但是，我想让文本框的值=当前日期，如果他们没有权限更改值。我可以用这个HTML扩展禁用它瓦特/权限：

public static MvcHtmlString TextBoxWithPermission(this HtmlHelper htmlHelper, 
                string name, 
                object value, 
                string[] permissions, 
                object htmlAttributes) 
{ 
    foreach (string permission in permissions) 
    { 
     if (Chatham.Web.UI.Extranet.SessionManager.DisplayUser.IsInRole(permission)) 
     { 
      // the user has the permission => render the textbox 
      return htmlHelper.TextBox(name, value, htmlAttributes); 
     } 
    } 

    // the user has no permission => render a readonly checkbox 
    var mergedHtmlAttributes = new RouteValueDictionary(htmlAttributes); 
    mergedHtmlAttributes["disabled"] = "disabled"; 
    return htmlHelper.TextBox(name, value, mergedHtmlAttributes); 
} 

但我怎么用当前日期填充它，如果它被禁用？

如果我正在阅读此权限，您只是想将当前日期作为无权限情况下的值传递给TextBoxWithPermission传入的值，而不是传递给TextBoxWithPermission中的值？

// the user has no permission => render a readonly checkbox 
var mergedHtmlAttributes = new RouteValueDictionary(htmlAttributes); 
mergedHtmlAttributes["disabled"] = "disabled"; 
return htmlHelper.TextBox(name, DateTime.Now, mergedHtmlAttributes);
