How do I get the collection of errors in a view?

I don't want to use the Html Helper Validation Summary or Validation Message. Instead I want to check for errors and if any display them in specific format. Also on the input controls I want to check for a specific property error and add a class to the input.

P.S. I'm using the Spark View Engine but the idea should be the same.

So I figured I could do something like...

<if condition="${ModelState.Errors.Count > 0}">
  DispalyErrorSummary()
</if>

....and also...

<input type="text" value="${Model.Name}" class="?{ModelState.Errors["Name"] != string.empty} error" />

....

Or something like that.

UPDATE

My final solution looked like this:

<input type="text" value="${ViewData.Model.Name}" class="text error?{!ViewData.ModelState.IsValid && ViewData.ModelState["Name"].Errors.Count() > 0}" id="Name" name="Name" />

This only adds the error css class if this property has an error.
