I used Custom Control class to create a panel that can hold many layers of controls separately, but I needed to add an in-editor usable button like "Add Layer" or "Remove Layer". I looked over default controls and found that TabControl has like two link labels ("Add Tab", "Remove Tab") that actually adds and deletes tabs in real time.
The problem I got is that I can't find no references to that funcionality of controls, and therefore, can't implement it in my custom control.
I couldn't find my problem in other posted questions and not also in internet. I tried searching in source code of referred controls, but I didn't find a reference.
Thanks in advance and sorry if there are mistakes in my english.
