HMI and Files

Hello,

My question is that I have some "text inputs" on my hmi and I want the user to be able to store what is inside of them in a file, but also be able to read the file and fill them. I would also like to be able to check if the values inside the text inputs are between a valid range and maybe display error messages which depend on the values of the other text inputs. Can I do all of these checks/saves/reads using C#?

Which then translates the question as: how can I connect hmi button clicks to events in my C# which can also read the available values of my text boxes?

You can also check the attached screenshot.

Thank you for your time once again.
