Hi,

I just came across a very interesting issue. If I use ViewData to pass a DateTime value to the view and then display it inside a textbox, even though I'm using String.Format in the exact same manner, I get different formatting results when using the Html.TextBox helper.

<%= Html.TextBox("datefilter", String.Format("{0:d}", ViewData["datefilter"]))%>
<input id="test" name="test" type="text" value="<%: String.Format("{0:d}", ViewData["datefilter"]) %>" />

The above code renders the following html:

<input id="datefilter" name="datefilter" type="text" value="2010-06-18" />
<input id="test" name="test" type="text" value="18/06/2010" />

Notice how the fist line that uses the Html helper produces the date format in one way while the second one produces a very different output. Any ideas why?

Note: I'm currently in Brazil, so the standard short date format here is dd/MM/yyyy.
