Usually, the easiest way for templates customizations is to use Expression Blend to generate the needed templates and resources and then make your own customizations upon them. In Expression Blend open your Silverlight project, select RadComboBox
in Objects and Timeline, right-click it and choose from the menu Edit Template-> Edit A Copy
. Then Blend will generate all the necessary templates and resources and you can easily modify them. More information about customizing RadComboBox
you could find in our online documentation
. Keep in mind the visual state brushes come from the ButtonChrome control placed in a certain control template. And in most cases in order to customize how a control looks in a normal, mouse over or other state, the ButtonChrome should be styled.
If you do not want to use Blend you can get the same Styles from RadControls
installation folder on your machine. There you will find a Themes folder. Drill down to the xaml file that corresponds to the control and its theme and you will have all needed resources for customizing the control manually.
Hope this is helpful.
