How to change background colour across multiple forms? - Thoma$ - Aug 10, 2016
So i'm trying to create a series of radio buttons on one form which will then change the background colour of all forms in the program to the corresponding selection. this.backcolor only applies the colour to the form it's located on so that's not what im looking for. Any help would be appreciated.

Can you provide some source code to check what are you doing?

Form1.Backcolor , Form2.Backcolor will work.

The above would work and its an EZ solution however i think there is another way as well ,
As i did not tested following but it would seem logical and more elegant way of doing this , is to make a BaseForm , let all the other forms you want to change color of inherit from that BaseForm , when you change the color of the BaseForm => all derrived forms will change as well.
You can also work with an event that is triggered on the change of the color , pass the color (code or whatever it is your using) as parameter and that should work as well.

I'm guessing your trying to change back color of all forms that are open and visible to the user, here's an easy foreach loop to change the background of all open forms...
PHP Code
<?php
foreach (Form f in Application.OpenForms)
{
f.BackColor = System.Drawing.Color.Grey
return;
}

It's this stuff that makes me wonder why people still use WinForms. In WPF this could be easily accomplished without needing any code-behind directly manipulating the user controls.

If it's an option that you just set one time, then instead of setting them at some later point in runtime, why not just create your own container/form?.

Who cares? You still need XAML.

No it won't actually, that only works in vb. That shouldn't even be a thing because it confuses developers who are used to OOP programming.

You don't need the unnecessary smell. You can have static resources for setting control properties. I just don't see the point in using something out-dated by 20 years when objectively better things are available. Especially if you are going to be manipulating the view like OP is.

All he's doing is changing the color of the background lol... Honestly for something this minimal in terms of graphic manipulation, what benefit will WPF have over WinForms? There's absolutely none. It's not like there's massive amount of graphics processing to be done here. WPF does better with more intricate GUI's, but there's hardly any difference with something this insignificant.
Btw, WinForms is not outdated and probably never will be unless Microsoft makes considerable change to the core of their operating system because they would break a lot of backwards compatible features and existing ones for the desktop if they were to remove the components that WinForms rely on. We can all take this "out-dated" vocabulary as a matter of of your misinformed opinion in this case; you can't consider something out-dated just because it's been around for a long time and it still works, and especially when the internals of .NET 4.0 have written components for GDI showing that Microsoft is still in no way ready to give up support for it.

He's changing the background color across multiple forms which leads me to believe he is also doing other things involving the view. It's not just the simple task, it's that based on even wanting to do this I am assuming much more is also being done or will be done. WinForms is good for fast development. WPF is good for a more interactive(For lack of a better word) interface. Based on the OP, I believe it is reasonable to assume he is most likely aiming for something that is, or is going to be, quiet involved with the UI - Which WPF is great for.

Thought i'd give you guys some context. I'm making a simple game for my school project and theres a customization menu which contains all the radio buttons which will change the form's colours. Gonna try some of the solutions mentioned now.

Why make it return after the first iteration?
