[Feature Request]: KryptonForm Enhancement - A option to disable/enable the close button

[PWagner1]

There are already options to do this with the maximise & minimise, but why not the close button?

@Wagnerp Do you mean the equivalent of these ?

i.e. to make them visible or not,
Or, is this a runtime setting you have found ?

@Smurf-IV Yes, currently the only similar way to do it is to 'hide' the control box. But that then hides the other two controls.

Ok, I have found the code:

And in the Max / min button classes this sort of thing:

So to make it "Work" it will need to be both a designer AND a programmatic thing?
i.e.

1. Make is Visible / invisible like the max . min designer
2. AND make it programmatic based on a "User" condition value as well ?

Something similar to this https://www.codeproject.com/Articles/93959/WinForm-Extended

CloseButton:

I added a new property called CloseButton. By setting this property to false, the window close button will be grayed out and > the user will no longer be able to close the form. The form is still closable if: The parent form gets closed, the task manager > closes the application, windows shuts down or there is a call to Application.Exit()

Colour changes may need to be done in the 2010/13/365 themes as well. I think I've added a '// Note:' prompt in them

There is something in the "Ribbon Control" that ignores the settings !!
Anyway, Does this need to disable "Alt+F4" if the Close is Disabled / inivisible ?

No, though it could be added sometime in the future...

Design time visibility (Similar to the Max / Min):

Programmatic Enabled (Disable) of the button:

Caveat with the Disabling of the button, is that the Code needs to handle the "Alt+F4" action themselves.
