I have a radio button and I want to set its 'Enable' property as 'off' in a specified situation, but Matlab report error as:
No appropriate method, property, or field 'Enable' for class 'matlab.ui.container.ButtonGroup'.
this feature should be available in others such as drop down list, etc.
is there any mistake with my operation?
Bests,
Yu

As of R2020b ButtonGroup and Panel both support Enable when the button group or panel is parented to a uifigure.

Enabled property is not valid for Button Group but valid for Button. So, app.Button.Enable = 'off' will work.
%% Create UIFigure
app.UIFigure = uifigure;
app.UIFigure.Position = [100 100 640 480];
app.UIFigure.Name = 'UI Figure';
% Create ButtonGroup
app.ButtonGroup = uibuttongroup(app.UIFigure);
app.ButtonGroup.Title = 'Button Group';
app.ButtonGroup.Position = [282 115 123 106];
% Create Button
app.Button = uiradiobutton(app.ButtonGroup);
app.Button.Enable = 'off';
app.Button.Text = 'Button';
app.Button.Position = [11 60 58 22];
app.Button.Value = true;
% Create Button2
app.Button2 = uiradiobutton(app.ButtonGroup);
app.Button2.Enable = 'off';
app.Button2.Text = 'Button2';
app.Button2.Position = [11 38 65 22];
% Create Button3
app.Button3 = uiradiobutton(app.ButtonGroup);
app.Button3.Text = 'Button3';
app.Button3.Position = [11 16 65 22];
%% Disable all buttons
app.Button.Enable = 'off';
app.Button2.Enable = 'off';
app.Button3.Enable = 'off';
Also, Button Group has Visible property, so you can hide button group by the following.
app.ButtonGroup.Visible = 'off';
