In my SfRadialMenu I have a few SfRadialSlider controls behind SfRadialMenuItems. For my use, I want to manually set the value property of the SfRadialSlider control when it's being opened, and then use the existing ValueChanged event to push changes. I don't see any kind of 'Opening' type of event on the SfRadialMenuItem, and I was hoping there was some other way I could hook to the menu items opening. Anyone know how I might be able to accomplish this?
