c# - How to reset a WPF control's default opacity toggling via IsEnabled after setting opacity explictly? -

-

when disable control (button), dark hard read text.

so using extension method set opacity 1.0 (100%) can read easily, when disabled:

public static void isenabledspecial(this system.windows.uielement control, bool isenabled) {     control.isenabled = isenabled;     control.opacity = 1.0;          // makes disabled control more readable }

normally, when opacity not explicitly set wpf control, appears toggle between 1.0 (100%) when control enabled , 0.35 (35%) when control disabled.

once explicitly set opacity using extension method, control thereafter ceases toggle between 1.0 , 0.35 when set isenabled without extension method. gets "stuck" @ 1.0 (100%), when isenabled set false;

after set opacity, how can later reset control normal opacity toggling between 1.0 , 0.35?

the changing of opacity being done through triggers. setting value directly, overriding value may produced style or triggers. not way go doing sort of thing. should using styles , triggers of own.

however, may able achieve want clearing value assigned opacity:

control.clearvalue(uielement.opacityproperty);
