Hello everyone,
I am wondering if it is possible to access the private properties of the UI component in the external function. In my example, I have an EV_lite component and inside of it I use a “DropDownValueChanged” callback which executes a function outside the component:

However, this function gives us an error, because it requires a private property “CategoryEVDropDown”:

I have dozens of such properties. Could you advise how to declare these private properties as public or access them directly outside of the component?
Or the only option is to put all the code inside of the component?
Thank you in advance!

Hello Aleksandr,
I understand that you are trying to create a private property of the UI component, but you cannot access that function outside the component.
In MATLAB App Designer, you can create public UI components in the following ways
properties (Access = public)
CategoryEVDropDown
end
You can refer to the below documentation to learn more about MATLAB App Designer properties.

Also from you function, It seems like you need the "DropDown" value instead of whole component
So it is recommended to pass "DropDown" value from the component to the function, instead of whole Component.
