Jquery datepicker not viewable

I an using JQuery datepicker on my asp.net page and I can't see "Prev" or "Next" buttons but I can click on them. Where can I change the color of these buttons or make them viewable? I tried with ot开发者_JAVA技巧her themes, but still same result.

Thanks.

If you are using the downloaded theme, make sure that the images in the theme are in the right location. Otherwise maybe they're being hidden by one of the css classes you have. Here's the html that the plugin generates:

<span class="ui-icon ui-icon-circle-triangle-w">Prev</span>
<span class="ui-icon ui-icon-circle-triangle-e">Next</span>
