I have created a dynamic mask, which change if the block parameter "Command" is equal to Reset. The Command is set when I click apply, then it hides the Channel and Channel Electrical Parameters inputs, see below

I would like to improve my mask and make it more dynamic, without the need to click on Apply.

I put the piece of code that is in my Mask Editor belwo. Can anyone advise on how to get access directly to the selected Command?

disp('AD5665r')
mask = Simulink.Mask.get(gcb);
switch get_param(gcb,'Command') % I suppose this is where I need to change the code
    case {'Write_To_Input_Register_n' ,'Write_To_Input_Register_n_And_Update_all' ,'Write_To_And_Update_DAC_Channel_n'}
        [control,handle]=mask.getDialogControl("ChannelA_param_container");
        control.Visible='on';
        mask.getParameter("Channel").Visible = 'on';
        
        port_label('input', 1, 'VoltageSetpoint')
    case 'Reset'
        [control,handle]=mask.getDialogControl("ChannelA_param_container");
        control.Visible='off';
        mask.getParameter("Channel").Visible = 'off';
        
        port_label('input', 1, 'ResetTrigger')
end
port_label('output', 1, 'i2c status')

I am assuming the code you provided is from the "Initialization" tab? You could try putting the same code in the "callback" for the Command parameter on the Mask Editor -> Parameter and Dialog pane.

No, it is from the Icon and Ports. the initialization tab contains the following code, which modify blocks under the mask. Though using the same piece of code (minus the function port_label() ) works very well.

Many thanks

Sylvain
