Ok, I figured it out (and it was pretty straightforward...). Posting one of my overloads in case anyone else runs into this question.

<pre><code>public static string DatePickerFor&lt;TModel, TProperty&gt;(this HtmlHelper&lt;TModel&gt; htmlHelper,Expression&lt;Func&lt;TModel, TProperty&gt;&gt; expression)
 where TModel : class
{
 var inputName = ExpressionHelper.GetExpressionText(expression);
 return htmlHelper.DatePicker(inputName);
}
</code></pre>

}|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|1350741|我用的是ModelMetadata，如果你为datepicker创建了一个datetime模板，它也会起作用。|unstyled|1350742|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|J|8|@]|9|@]|A|$]]|$1|G|3|-4|5|F|7|K|8|@]|9|@]|A|$]]]|H|$]]

 where TModel : class
{
 ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
 return htmlHelper.DatePicker(metadata.PropertyName);

</code></pre>

I used ModelMetadata this will also work if you create a datetime template for datepicker.

blocks|key|1135569|text|我刚刚尝试了以下方法来创建一个强类型的CKEditor帮助器，它似乎可以完美地工作。这里假设您已经在项目中包含了jquery和必要的ckeditor脚本。同时设置ckeditor配置可能很好，但这满足了我当前的需求。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1135570|++++public+static+MvcHtmlString+CkEditor(this+HtmlHelper+htmlHelper,+string+name,+string+value,+object+htmlAttributes)

I just tried out the following to create a strongly typed CKEditor helper and it seems to be working flawlessly. This assumes that you already have included jquery and the necessary ckeditor scripts in your project. It might be nice to look at also setting the ckeditor config too, but this satisfied my current needs.

<pre><code> public static MvcHtmlString CkEditor(this HtmlHelper htmlHelper, string name, string value, object htmlAttributes)
 {
 var output = htmlHelper.TextArea(name, value, htmlAttributes).ToString();
 output += string.Format("&lt;script type=\"text/javascript\"&gt;$(document).ready(function(){{ $('#{0}').ckeditor(); }});&lt;/script&gt;", name);

 return MvcHtmlString.Create(output);
 }

 public static MvcHtmlString CkEditor(this HtmlHelper htmlHelper, string name, string value)
 {
 return htmlHelper.CkEditor(name, value, null);
 }

 public static MvcHtmlString CkEditorFor&lt;TModel, TProperty&gt;(this HtmlHelper&lt;TModel&gt; htmlHelper, Expression&lt;Func&lt;TModel, TProperty&gt;&gt; expression, object htmlAttributes) where TModel : class
 {
 ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
 return htmlHelper.CkEditor(metadata.PropertyName, metadata.Model as string, htmlAttributes);
 }

 public static MvcHtmlString CkEditorFor&lt;TModel, TProperty&gt;(this HtmlHelper&lt;TModel&gt; htmlHelper, Expression&lt;Func&lt;TModel, TProperty&gt;&gt; expression) where TModel : class
 {
 return htmlHelper.CkEditorFor(expression, null);
 }
</code></pre>

I was wondering if it is possible to create a custom strongly typed HTML Helper in ASP.NET MVC 2? Creating a regular (read not-strongly-typed) helper is straightforward but i am having difficulty creating strongly typed versions. For example, I would like to create a DatePickerFor html helper...

Any guidance or snippets would be greatly appreciated,
Thank you in advance!

Is it possible to create a custom ASP.NET MVC strongly typed HTML Helper?

我想知道是否有可能在ASP.NET MVC2中创建一个自定义的强类型HTML Helper？创建一个常规的(读不是强类型的)帮助器很简单，但是我在创建强类型版本时遇到了困难。例如，我想创建一个DatePickerFor html助手...任何指导或片段都将不胜感激，提前谢谢！JP
