Hello,
There's an RibbonTabItemSelected event on the RibbonTabItem class that is fired when a new tab has been selected, but is there an event that is fired before selecting the new tab (with the possibility to cancel the selection) ?
Thanks
No. The xamRibbon contains a derived TabControl (which is itself just a derived Selector). Neither TabControl nor Selector provide any means to prevent selection changes. Also, according to the UI guidelines clicking on a tab in the ribbon must select the tab and display its contents.
