Complete the following steps:

1. Click the C1Dialog smart tag to open the C1Dialog Tasks menu.
2. In the Theme drop-down box, enter a URL to specify the theme; URLs can be found at
   http://blog.jqueryui.com/2011/06/jquery-ui-1-8-14/. In this example, we'll use the swanky-purse theme: http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.14/themes/swanky-purse/jquery-ui.css

   

   This theme setting is stored in the <appSettings> of the Web.config file. In the Solution Explorer, double-click the Web.config file. Notice the <appSettings> tag contains a WijmoTheme key and value; this is where the CDN URL you added is specified.

3. Run the project and notice that the theme has been applied to C1Dialog.
