I have some RadToggleButtonElements in a RadRibbonBar, and I'm trying to apply a theme to them. I already have a theme manager assigned to the ribbon bar, and it appears to be working correctly for the other control types on the ribbon bar. The RadToggleButton theme is loaded into the theme manager but it isn't being applied to the toggle buttons. I've checked the IsThemeApplied property on the buttons at runtime just to be sure, and it's always false. I found a previous post (http://www.telerik.com/forums/toggle-button-style) about how to add a RadStylesheetRelation to the RadToggleButton theme's xml file, and I tried that, but it's still not working. Is there something else I'm missing?
Note: This same RadToggleButton theme is used on another form as well, and it's working there, so I don't believe there's anything wrong with the theme itself. The only difference that I can see is that the toggle buttons on the other form are not being used in a ribbon bar.
