assuming Form1 knows about Form2 that's easy just set a property on the instance of Form2 from Form1 or pass it in via a method

it's like i have one main form like main menu then 3 forms which have reference of Mainmenu and i want the data from form1 to form2 not from main menu D:

Keep the data unaware of the forms, that way you have more control over it.

meaning, don't store the data within the forms

I don't see how this changes anything I just said you can just pass it along like I assume there's some relationship here that'll allow you to pass the information around so fundamentally its just a case of adding APIs that let you do that

so you have the child form you already change stuff on it when the button is clicked from what you're showing me here just give it the image as well? like this looks to only take the base type so obv you're gonna need to do it at a point where you know what form it is you're working with but the gist is the same literally you can just be like

ItemUpgradeMenu menu = new();
menu.PictureOfItem = MyPictureBox.Whatever;

ItemUpgradeMenu menu = new();
menu.PictureOfItem = MyPictureBox.Whatever;

and you done you just need to expose something on your item upgrade menu for taking the picture and then pass it along
