I have a layout with PopUpMenuA and TextboxB.
I would like to be able to either enable or disable TextboxB depending on the value selected in PopUpMenuA.
If the user selects Yes in PopUpMenuA, I would like the user to be able to enter a value in Textbox B.
If the user selects No in PopUpMenuA, I would like the user to not be able to enter a value in TextboxB.
Is there a recommended way to accomplish this?
