What button called this form?

I have 2 problems:

  • "Which button is called this form?" (short version)

  • I can not press a button or a button

Why do I need it?

I have many forms and I need to know how the user got there. If I could get a form (not a button), it could also solve the problem.

Long version: I need to copy some properties of the original form / button to a new one without doing it manually, and I intend to use it later in the exception report to find out more information

At first I tried to do "newForm.Caller = this;" on each button, but there are 200+ forms and many buttons on each.

All forms and buttons are user controls, so I can do something there.

Tried things

  • I tried to do things with StackFrames and reflect on the constructor of the form, but it doesn't work ( 889310 )

  • I found this 10401190 for JAVA but it cannot help

  • I thought I could use the OnClick override to store the last instance of the button in a static place in the button / form class, and then get it in the form constructor, but this seems to be the worst solution. (Many open forms, and the culprit will be the last button pressed)

  • The problem gets worse when other things open Forms and I lost the link (DataGridVewButton, timers, associated label, ...)

EDIT1: (oɔɯǝɹ) Another detail, forms can be called from external plugins. Thus, I again do not have access to the code to change it.

EDIT2: (Graham Bass, ShreyasKapur) FormA ButtonA, FormB FormA FormBase ButtonBase FormB FormBase

FormA ButtonA, FormBase ButtonBase
