Please follow the steps as outlined by the arrows in the attached picture. Basically, what you should do is

1) Select the Design View AppDesigner

2) Select the Component Whose Id You Want To Know

3) The highlighted text under the app.UIFIGUREin the Component Browser pane is the full ID of the selected component.

So if you selected a button whose text is "Select File" then in the Component Browser under app.UIFIGURE, the text app.SelectFile will be full id of the selected component.

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';

You can call the button pushed callback function programmatically, so if your callback looks like this,

 % Button pushed function: Button
 function ButtonPushed(app, event)
     % Do something       
 end

you can call it by the following.

ButtonPushed(app, matlab.ui.eventdata.ButtonPushedData)
