I am using Microsoft Visual Studio Professional 2022. I'm creating forms programmatically adding content based on a JSON configuration, I need to set the size of the controls according to the configuration and this isn't working. In the debugger I can see the Height of a ListBox is 20, if I try to set the Height to 200 no error or exception occurs but the new value is not assigned.

I have added OnSizeChanged and added it to each control, I'm not sure what this is supposed to show me.

Can anyone help?

    You should really post the code you're using for this task, also making clear in what context that code is run -- You don't add OnSizeChanged to a standard Control, you override that method in a Custom Control. Irrelevant here -- Are you sure you're not referring to, e.g., a TextBox instead? Commented yesterday

    When height is reverted, OnSizeChanged will be invoked, so you can know who changes the height from the callstack. Commented yesterday
