Disable checkbox on button click

[assop]

Hello,

I have 4 checkboxes and 1 button, it's a screen with test, so i don't want user to change his marks in any checkbox more than once. 

So how can I disable checkboxes after pressing a button?

I tried to write in a checkbox1 displaymode this: 

If(Button3_19.Pressed,DisplayMode.Disabled, DisplayMode.Edit)

But it disables checkbox only while I keep the button pressed. 😥

OnCheck of the Checkbox, create a variable;
UpdateContext (DisabledCheck,true)

Or use a set variable;
Set(DisabledCheck,true)

Then in the Displaymode;
If(DisabledCheck,DisplayMode.Disabled, DisplayMode.Edit)
