I'm curious if there is a "check all" kind of thing for a tablelayoutpanel?

To explain, say I have TableLayoutPanel1 with 6 radio buttons and I'm doing an error check to make sure that at least one radio button has been selected during a click event. Do I have to do If / and with all 6 radio buttons? Or is there something like "If TableLayoutPanel1.checked(obviously not this) = false then"

Any help is greatly appreciated!
