One option is to use a RadioButtonTool for the purpose of a ToggleButton.

Hope this helps,
Thanks Duane, I know it's possible to put a custom control on the ribbon, the thing I concern is if I just put a SL togglebutton on there, it won't look the same as other buttons, is there anyway I can make them as consistent as possible?
Hello Daniel,
As far as a built in ToggleButton for the xamRibbon is currently only in WPF platform for NetAdvantage. For flexibility you may be able to create a custom tool by inheriting RibbonTool and implementing RibbonToolBaseControl. A sample is available in this forum thread post here: http://forums.infragistics.com/forums/p/48137/256144.aspx.
Let me know if you have any questions with this matter. Thank you.
