title: ASP.NET textbox cssClass gets overrwritten in GridView ItemTemplate after rendering
body: <p>I have a textbox inside a TemplateField column for a gridview. When I set the cssClass property for the textbox, it gets overwritten by a "textBox" class in the rendered web page. Is this normal behavior?

  <p>As a workaround I added a 'style' attribute.</p>
